A correct diet is very important to keep the prostate healthy and prevent many diseases affecting this organ.

Caldo e prostata: perché in estate i sintomi possono peggiorare

, , ,

Con l’arrivo dell’estate, alcuni uomini riferiscono un peggioramento dei disturbi urinari: maggiore frequenza, urgenza, risvegli notturni per urinare o sensazione di svuotamento incompleto.

È naturale chiedersi se il caldo possa “fare male alla prostata”. La risposta più corretta, dal punto di vista scientifico, è questa: il caldo non è una causa diretta dimostrata di patologie prostatiche, ma può creare condizioni che rendono più evidenti o più fastidiosi i sintomi urinari, soprattutto negli uomini che hanno già benign prostatic hyperplasia (BPH), prostatitis or Lower Urinary Tract Symptoms (LUTS).

I LUTS maschili, infatti, non dipendono solo dalla dimensione della prostata. Possono essere legati all’ostruzione causata dall’ipertrofia prostatica benigna, ma anche alla funzione della vescica, alla frequenza minzionale, all’assunzione di liquidi, alle abitudini alimentari e ad altri fattori comportamentali. Per questo, durante l’estate, cambiamenti apparentemente semplici, bere meno, sudare di più, assumere più alcol o caffeina, modificare la dieta o trattenere più a lungo l’urina, possono avere un impatto concreto sulla percezione dei sintomi. [urologyclinics.com], [nature.com]

Il ruolo chiave dell’idratazione

Uno dei fattori più importanti è l’idratazione. Con temperature elevate, l’organismo perde più liquidi attraverso la sudorazione. Se questi liquidi non vengono reintegrati in modo adeguato, il volume urinario può ridursi e le urine possono diventare più concentrate. Dal punto di vista fisiologico, un buon flusso urinario contribuisce alla normale “pulizia” delle vie urinarie, mentre una riduzione della diuresi può favorire ristagno e maggiore concentrazione di sostanze potenzialmente irritanti. [europeanurology.com], [jamanetwork.com]

Questo non significa che la disidratazione causi direttamente problemi alla prostata. Più correttamente, può contribuire a un peggioramento dei sintomi urinari in chi è già predisposto. Una revisione sistematica ha mostrato che un aumento dell’assunzione di liquidi può ridurre il rischio di infezioni urinarie ricorrenti in soggetti predisposti, confermando l’importanza dell’idratazione per la salute del tratto urinario. [jamanetwork.com]

È però importante evitare un messaggio troppo semplicistico. Bere di più non significa necessariamente bere “molto e tutto insieme”. Studi sui LUTS maschili indicano che la quantità e la distribuzione dei liquidi possono influenzare in modo diverso i sintomi: una maggiore assunzione di acqua può associarsi a migliori sintomi di svuotamento, ma anche a maggiore frequenza o urgenza in alcuni soggetti. Per questo le linee guida raccomandano un approccio personalizzato, ad esempio riducendo l’assunzione di liquidi nelle ore serali se il problema principale è la nicturia. [guidelinecentral.com] [nature.com], [wjmh.org]

Caldo e infezioni urinarie

Un altro aspetto riguarda le infezioni delle vie urinarie. Studi epidemiologici hanno evidenziato che le temperature più alte sono associate a un aumento dell’incidenza di infezioni urinarie, con un incremento osservato soprattutto nei mesi più caldi. In uno studio pubblicato sul Journal of Urology, temperature medie settimanali tra 25°C e 30°C sono state associate a un aumento del 20–30% del rischio di infezioni urinarie rispetto a periodi più freddi. [guidelinecentral.com]

Questa evidenza riguarda principalmente le infezioni urinarie in generale, e in particolare popolazioni femminili, quindi non va interpretata come prova diretta che il caldo provochi prostatite negli uomini. Tuttavia, negli uomini alcune infezioni urinarie possono coinvolgere anche la prostata e manifestarsi come prostatite batterica, soprattutto quando sono presenti fattori favorenti come ristagno urinario, ostruzione o svuotamento incompleto. [link.springer.com], [jamda.com]

In altre parole, è più corretto dire che il caldo può aumentare il rischio di condizioni che favoriscono disturbi urinari o infezioni, e che in alcuni uomini queste infezioni possono interessare anche la prostata. Non è invece corretto affermare in modo diretto che “il caldo causa prostatite”.

L’impatto sui sintomi urinari (LUTS)

Quando si parla di sintomi come getto debole, urgenza, nicturia o sensazione di svuotamento incompleto, spesso si pensa immediatamente alla prostata. In realtà, i LUTS sono il risultato di un’interazione complessa tra prostata, vescica e sistema urinario. Possono derivare da un’ostruzione al deflusso urinario dovuta all’ipertrofia prostatica benigna, ma anche da una vescica iperattiva o da alterazioni funzionali non direttamente legate alla dimensione prostatica. [urologyclinics.com], [nature.com]

È proprio questa complessità a spiegare perché l’estate possa rappresentare un periodo critico per alcuni uomini. Non perché la prostata “si infiammi con il caldo” in modo automatico, ma perché cambiano le condizioni intorno al sistema urinario: idratazione, concentrazione delle urine, abitudini alimentari, consumo di bevande irritanti, attività fisica, viaggi e routine quotidiana.

Caldo, infiammazione e prostatite

La prostata è un organo sensibile ai processi infiammatori e infettivi.

La prostatite, che può essere batterica o non batterica, è spesso associata a sintomi urinari e dolore pelvico, e in molti casi deriva da infezioni ascendenti delle vie urinarie. [jamanetwork.com]

Fattori che favoriscono infezioni e ristagno urinario, come:

  • disidratazione
  • ridotta frequenza minzionale
  • ostruzione urinaria (tipica dell’IPB)

sono riconosciuti come elementi che aumentano il rischio di infiammazione prostatica. [nature.com]

In un contesto estivo, questi fattori tendono a combinarsi, creando condizioni favorevoli a una riacutizzazione dei sintomi.

Non solo temperatura: lo stile di vita estivo

Durante l’estate può aumentare il consumo di bevande alcoliche, caffè freddo, tè, bibite zuccherate o gassate. Alcol e caffeina possono avere effetto diuretico e irritante sulla vescica, contribuendo ad aumentare frequenza, urgenza e nicturia in alcuni soggetti. Le linee guida europee sui LUTS maschili includono infatti tra le modifiche comportamentali la moderazione di caffeina e alcol, soprattutto nei pazienti che riferiscono sintomi di riempimento o disturbi notturni. [nature.com], [wjmh.org]

Anche il momento in cui si beve conta. Bere grandi quantità di liquidi la sera, magari dopo una giornata calda, può aumentare la probabilità di doversi alzare durante la notte per urinare. Per questo le strategie consigliate non puntano a ridurre indiscriminatamente l’acqua, ma a distribuirla meglio durante la giornata, evitando eccessi nelle ore serali nei pazienti con nicturia. [nature.com], [wjmh.org]

Cosa fare in pratica

Per chi soffre di sintomi urinari o problemi prostatici, alcuni accorgimenti possono aiutare a ridurre il rischio di peggioramento:

  • mantenere un’idratazione regolare durante la giornata, evitando sia la disidratazione sia grandi quantità di liquidi concentrate in poche ore; [jamanetwork.com], [nature.com]
  • limitare alcol e caffeina se si nota un aumento di urgenza, frequenza o nicturia; [nature.com], [wjmh.org]
  • non trattenere troppo a lungo l’urina, perché il regolare svuotamento vescicale contribuisce alla fisiologica difesa delle vie urinarie; [europeanurology.com], [jamda.com]
  • prestare attenzione a sintomi nuovi o persistenti, come bruciore, febbre, dolore pelvico importante, sangue nelle urine o difficoltà marcata a urinare, che richiedono valutazione medica. [link.springer.com], [urologyclinics.com]

Questi suggerimenti non sostituiscono il parere del medico, ma possono aiutare a gestire meglio i disturbi urinari nei mesi caldi.

Il caldo non deve essere considerato una causa diretta di malattie della prostata. Tuttavia, può contribuire al peggioramento dei sintomi urinari attraverso meccanismi indiretti: maggiore perdita di liquidi, urine più concentrate, variazioni nell’assunzione di acqua, aumento del consumo di alcol o caffeina e possibile incremento del rischio di infezioni urinarie. [guidelinecentral.com], [jamanetwork.com], [nature.com]

Il messaggio chiave è quindi semplice: in estate la prostata non diventa necessariamente “più malata”, ma il sistema urinario può diventare più vulnerabile agli effetti di disidratazione, abitudini scorrette e infezioni. Per chi ha già LUTS, ipertrofia prostatica benigna o una storia di prostatite, prestare attenzione a questi fattori può fare la differenza nella qualità della vita quotidiana.

Estratti di tè verde e salute della prostata

,

Le catechine del tè verde sono tra le molecole naturali più studiate per il loro potenziale nella salute della prostate: dal ruolo antiossidante e antinfiammatorio, alla capacità di modulare vie ormono‑dipendenti e processi cellulari chiave.

Che cosa contengono davvero gli estratti di tè verde

Il tè verde (Camellia sinensis) è ricco di catechine, una famiglia di flavan‑3‑oli a cui appartengono soprattutto EGCG (epigallocatechina‑3‑gallato), EGC, ECG ed EC; tra queste, l’EGCG è la più abbondante e la più studiata per attività biologica e rilevanza farmacologica.

Oltre alle catechine, le foglie contengono metilxantine (caffeina, teofillina, teobromina) e altri polifenoli minori. La bassa fermentazione del tè verde preserva meglio le catechine rispetto a tè nero o oolong (source).

Dal punto di vista dell’assunzione dietetica, le stime europee indicano che l’apporto quotidiano di EGCG attraverso infusioni tradizionali varia in genere tra 90 e 300 mg/die (con valori più alti nei forti consumatori), mentre gli integratori possono fornire 5–1.000 mg/die a seconda dei prodotti (source).

Come funzionano

Le catechine agiscono su più fronti biologici rilevanti per la prostata. In laboratorio e in modelli animali, EGCG ha mostrato proprietà antiossidanti e antinfiammatorie, modulazione del recettore degli androgeni, interferenza con vie di segnalazione pro‑proliferative, induzione di apoptosi delle cellule tumorali e, in alcuni contesti, inibizione di enzimi come 5α‑reduttasi.

A livello clinico, questi meccanismi si traducono in potenziali effetti chemiopreventivi più che terapeutici in malattia avanzata. Va sottolineato che l’effetto finale dipende da biodisponibilità, dose, formulazione e durata della somministrazione (source1, source2).

Dove si trovano e come si introducono nella dieta

Si può ricorrere a bevande (tè verde in foglia o matcha) o a estratti standardizzati (es. decaffeinati e titolati in EGCG o “green tea catechins”, come Polyphenon E o Sunphenon® nelle sperimentazioni cliniche).

Le bevande forniscono catechine distribuite nell’arco della giornata insieme al cibo; gli integratori concentrano la dose in poche assunzioni. Le linee informative dell’NCI (PDQ) includono il tè verde tra le strategie dietetiche studiate per la prevenzione primaria/secondaria del prostate cancer (source).

Che cosa dicono gli studi sulla prostate

Lesioni precancerose e prevenzione

È il campo con le evidenze più interessanti. In un clinical trial italiano su uomini con HGPIN or ASAP, una combinazione di catechine pari a 600 mg/die (≈ EGCG ~300 mg/die) per 12 mesi ha ridotto l’incidenza di cancro alla prostata dal 30% (placebo) a ~3% (trattati).

Nello stesso studio, nei soggetti con iperplasia benigna (BPH) concomitante è migliorato anche l’IPSS (sintomi urinari) (source).

Un trial statunitense più recente ha usato un estratto decaffeinato standardizzato (Polyphenon E, EGCG 400 mg/die per 12 mesi). Non ha ridotto il tasso di tumore primario rispetto al placebo, ma ha abbassato il PSA e ridotto lo sviluppo di tumore (source).

The Prostate Cancer, Nutrition, and Dietary Supplements del National Cancer Institute (aggiornato 20 dicembre 2024) riporta che per la active surveillance ci sono evidenze precliniche solide ed evidenze cliniche promettenti, ma non conclusive.

Malattia a basso rischio in active surveillance

Sono in corso studi clinici di fase II con catechine per 6–24 mesi (es. NCT04597359; NCT04300855) per valutare biomarcatori (Ki‑67, apoptosi) e progressione clinica. I risultati finali non sono ancora pubblicati, ma disegni e dosi (≈ 405 mg di GTC/die) indicano buona fattibilità e sicurezza come intervento complementare. (fonte 1, 2, 3).

“Finestra d’opportunità” pre‑prostatectomia

In pazienti candidati a chirurgia, somministrare EGCG 800 mg/die per 3–6 settimane ha mostrato modesti cambi (non significativi) in biomarcatori proliferativi e di angiogenesi: segnale che l’azione potrebbe essere indiretta o richiedere tempi/dosi/formulazioni diversi (source).

BPH/LUTS

Le prove cliniche dedicate sono scarse. Nello studio HGPIN del 2006 si è osservato come secondario un miglioramento dell’IPSS in uomini con BPH concomitante; mancano però studi clinici ampi e specifici su sintomi LUTS con estratti di catechine.

La letteratura più robusta sugli integratori per BPH riguarda altri fitocomposti (es. serenoa, zucca, fitosteroli), non il tè verde. In sintesi: potenziale beneficio sintomatologico suggerito, evidenza limitata (source).

Quanta EGCG serve?

  • Bevande: 3–5 tazze/die di tè verde ben preparato possono fornire ~150–500 mg/die di EGCG (dipende da cultivar, grammi di foglia, tempo e temperatura di infusione). Nei consumatori europei l’intervallo tipico è 90–300 mg/die. Se sensibili alla caffeina, preferire versioni decaffeinate o distribuire nell’arco della giornata.
  • Supplements: negli studi di prevenzione secondaria sono state impiegate due strategie:
    • EGCG 200 mg due volte al dì con il cibo (totale 400 mg/die) per 12 mesi, con buon profilo di sicurezza; [oncotarget.com]
    • Catechine totali 600 mg/die (miscela con ≈ 50% EGCG) per 12 mesi. [direct-ms.org]

Sicurezza regolatoria: l’EFSA segnala rischio epatico con ≥ 800 mg/die di EGCG dagli integratori; l’UE richiede etichette con avvertenze e porzioni < 800 mg EGCG. Per infusioni tradizionali non emergono problemi di sicurezza nella popolazione generale. Consiglio pratico: restare ≤ 400 mg EGCG/die, assunti con i pasti e in dosi frazionate. [air.unimi.it], [efsa.europa.eu], [cot.food.gov.uk]

Biodisponibilità: come migliorarla (senza complicarsi la vita)

L’EGCG ha biodisponibilità orale modesta e variabile. Tre accorgimenti hanno un razionale pratico: assumere con il cibo e in dosi divise (migliora tollerabilità epatica), acidificare la bevanda (es. aggiungendo agrumi) o co‑assumere vitamina C, che stabilizza le catechine lungo l’intestino, e considerare formulazioni a maggiore assorbimento (complessi fosfolipidici “phytosome”, nano‑delivery)—queste ultime supportate soprattutto da dati preclinici.

Cosa aspettarsi sui biomarcatori (PSA) e sui tessuti

Una meta‑analisi (2021) ha esaminato l’effetto del tè verde/estratti sul PSA: alcuni studi riportano riduzioni modeste (coerenti con quanto osservato nell’RCT Polyphenon E), ma l’eterogeneità è alta e l’interpretazione clinica rimane cauta. Studi pre‑chirurgici mostrano bassa penetrazione tissutale con cicli brevi, suggerendo la necessità di strategie che aumentino esposizione e durata.

Red meat and the prostate: how to regulate at the table

,

The relationship between red meat consumption and the health of the prostate is the subject of numerous scientific studies, with sometimes conflicting results.

What science says

A meta-analysis published in Frontiers in Nutrition (2022) included 25 prospective studies of almost 2 million men, showing that a high intake of processed meat (e.g. cured meats) is associated with a 6% increase in the risk of prostate cancer compared to those who consume less. However, the association with advanced prostate disease remains insignificant (source).

A previous meta-analysis (2015) on unprocessed red meat found associations with total and advanced prostate cancer that were not statistically significant (RR around 1.00 and 1.01 respectively). Instead, a slight association with processed meat emerged, but probably influenced by bias (source).

Finally, more than 20 cohorts of studies combined in 2015 IARC reports indicated only a weak and uneven association between red meat and total prostate risk, but showed a significant increased risk of advanced forms in specific North American populations, linking in particular high-temperature cooking (grilling, barbecuing) to the formation of compounds such as heterocyclic amines and polycyclic aromatic hydrocarbons (source) (source).

IARC and WCRF: Carcinogenesis and recommendations

The International Agency for Research on Cancer (IARC) classifies red meat as «probably carcinogenic» (Group 2A) and processed meat as «definitely carcinogenic» (Group 1). The World Cancer Research Fund and the American Institute for Cancer Research recommend limiting red meat to 350-500 g per week (cooked weight) and avoiding processed meats. [airc.co.uk], [wcrf.org] [ristorantelabrace.it]., [cancer.org]

In case of prostate disease or prevention

For those who already have benign prostatic hyperplasia (BPH), prostatitis or prostate cancer, it is prudent to further reduce the consumption of red meat, especially if it is often cooked at high temperatures.

Several articles on male health urge limiting intake precisely in the presence of prostate disorders (source), (source).

The guidelines of AIRC emphasise that while red meat can be part of a balanced diet, it should be consumed in moderation, and people at risk should discuss it with their doctor.

Recommended consumption and cooking methods

A limit of 350-500 g of red meat per week is considered compatible with an acceptable practical risk according to global guidelines (source), (source).

It is crucial:

  • Avoid processed meats (cold cuts, hot dogs...) or consume them very little.
  • Prefer lean cuts (fillet, sirloin).
  • Limit high-temperature cooking in favour of gentler methods (baking, steaming, stewing).
  • Marinating meat - can reduce the formation of harmful compounds.

What does it mean to you?

If you look at prostate health (both in prevention and in the presence of disease), the “less is more” rule applies to red meat, especially processed meat.

Following suggestions such as the Mediterranean diet, focusing on alternative protein sources (fish, chicken, pulses) and adopting healthier cooking methods helps maintain a nutritional balance without sacrificing taste.

The data do not indicate a strong and definitive relationship between unprocessed red meat and prostate cancer, but suggest a modest connection with processed meats and a possible higher incidence of advanced forms when cooked at high temperatures.

A measured consumption, combined with healthy eating habits and careful cooking styles, is the most sensible strategy for those who want to protect their prostate.

10 tips for prostate health

,

“Doctor, what can I do to prevent the prostate cancer?”.
This is one of the most common questions that doctors hear from men concerned about the health of the prostate.

Unfortunately, there is nothing that can guarantee that one will not develop a disease with certainty. There is always a probability of risk, but it can be reduced with a few simple lifestyle measures.

Adopt a healthy eating pattern

Instead of focusing on specific foods, dieticians, doctors and researchers advertise a general pattern of healthy eating, and healthy eating is easier than you might think.

In a nutshell, here is what the experts recommend:

  1. Eat at least five portions of fruit and vegetables every day. Choose those with bright, intense colours.
  2. Choose wholemeal bread instead of white bread and choose wholemeal pasta and cereals.
  3. Limit consumption of red meat, including beef, pork, lamb and goat, and processed meats, such as bologna and frankfurters. Fish, poultry, beans and eggs are healthier sources of protein.
  4. Choose healthy fats, such as olive oil, dried fruits (almonds, walnuts) and avocados. Limit saturated fats from dairy products and other animal products. Avoid partially hydrogenated fats (trans fats), which are found in many fast food and packaged foods.
  5. Limit sugary drinks, such as soft drinks and many fruit juices.
  6. Reduce salt. Choose low-sodium foods by reading and comparing food labels. Limit the use of canned, processed and frozen foods.
  7. Watch portion sizes. Eat slowly and stop eating when you are full.

Stay active and keep your prostate healthy

Besides eating a healthy diet, you should stay active. Regular exercise reduces the risk of developing some serious problems, including heart disease, stroke, and some cancers. And although relatively few studies have directly evaluated the impact of exercise on prostate health, those that have been done have concluded that exercise is beneficial. For example:

  • Based on the study questionnaires Health Professionals Follow-up Study, sponsored by Harvard University, compiled from over 30,000 men showed an inverse relationship between physical activity and symptoms of benign prostatic hyperplasia (BPH). Simply put, men who were more physically active were less likely to suffer from BPH. Physical activity of low to moderate intensity, such as walking regularly at a moderate pace, also produced benefits.
  • From the same study, a correlation was observed between erectile dysfunction and exercise. They found that men who ran for at least an hour and a half or did three hours of outdoor sports per week were 20% less likely to have erection problems than those who did not exercise at all. And the greater the amount of physical activity, the lower the risk. Interestingly, regardless of the level of exercise, men who were overweight or obese had a higher risk of erectile dysfunction than men with an ideal body mass index.
  • An Italian study recruited 231 sedentary men with prostatitis chronic and divided them into two exercise programmes for 18 weeks: aerobic exercise, which included fast walking, or non-aerobic exercise, which included leg lifts, abdominal exercises and stretching. Each group exercised three times a week. At the end of the study, men in both groups felt better, but those in the aerobic exercise group experienced significantly less discomfort, anxiety and depression and a better quality of life.

From this evidence we can therefore say that if you want to keep your prostate healthy:

  1. Do physical activity, starting with a low intensity, such as walking regularly at a moderate pace
  2. Try to gradually increase the intensity of your physical activity. But without overdoing it. listen to your body!
  3. Prefer aerobic activities, such as brisk walking or running, to non-aerobic activities, such as leg lifts or sit-ups.

Quercetin: a natural ally for the prostate

, , ,

The health of the prostate is a central issue in preventive medicine and quality of life for men, especially as they get older.

Among the many natural substances studied for their therapeutic potential, the quercetin has attracted the attention of the scientific community for its anti-inflammatory and antioxidant properties.

This flavonoid, found in many plant-based foods, has been shown to be particularly effective in counteracting the symptoms of chronic prostatitis and modulating the cellular processes involved in the development of prostate cancer.

Interest in quercetin stems not only from its efficacy, but also from its natural origin and the possibility of easily incorporating it into the daily diet or through targeted supplements.

What is Quercetin

Quercetin is a natural compound belonging to the flavonoid family, plant pigments responsible for the colour of many fruits and vegetables.

It is one of the most abundant flavonoids in the human diet and is found in many common foods.

Its chemical structure gives it antioxidant and anti-inflammatory properties, making it the subject of growing scientific interest for the treatment and prevention of various diseases, including those affecting the prostate.

Mechanisms of action

Quercetin acts on several fronts. Firstly, it is a powerful antioxidant: it neutralises free radicals, unstable molecules that damage cells and promote chronic inflammation. In addition, it has a direct anti-inflammatory effect as it inhibits enzymes and chemical mediators involved in inflammatory processes.

This is particularly relevant for the prostate, an organ prone to persistent inflammation, especially with advancing age.

Quercetin has also been shown in preclinical studies to have anti-cancer properties. It can induce apoptosis (programmed cell death) in cancer cells and inhibit their proliferation. Although these effects are still being studied, they represent an interesting prospect for the prevention of prostate cancer.

Food sources

Quercetin is present in many everyday foods.

Red onions, particularly in the outer layers, are an excellent source. Also capers, apples, grapes, berries, celery, cabbage, tomatoes and green tea contain significant amounts of it.

Interestingly, the red wine, due to the fermentation process, concentrates quercetin more than white wine.

Consumption of these foods, especially when combined with fats or carbohydrates, can improve intestinal absorption, which is otherwise rather limited.

Capers181 mgMore concentrated source; often consumed in small quantities
Red onions33-56 mgHigher concentration in the outer layers and if organically grown
Apples (with peel)4-44 mgFuji variety: approx. 2.3 mg; other varieties up to 4.0 mg
Red grapes3-15 mgThe peel contains most of the quercetin
Berries3-15 mgBlueberries, blackberries, raspberries; varies according to species
Celery3-5 mgModerate quantity; useful in combination with other foods
Cabbage7-10 mgBroccoli and green cabbage are good sources
Tomatoes1.6-3.3 mgOrganic tomatoes contain up to 79% more than conventional ones
Green tea2-10 mgVaries according to quality and preparation
Red wine3-5 mgHigher concentration than white wine

Integration and bioavailability

Despite its abundance in food, quercetin has a relatively low oral bioavailability. For this reason, specific supplements, often combined with bromelain, vitamin C or liposomal formulations, are available to improve its absorption.

Doses used in clinical trials vary from 250 to 1000 mg per day, generally for cycles of several weeks. It is important to follow the instructions of a health professional, especially in the presence of other drug therapies.

Quercetin and prostate health

Quercetin is particularly useful in the treatment of chronic non-bacterial prostatitis, an inflammatory condition that can cause pelvic pain, difficulty urinating and sexual discomfort. Several studies have shown a significant reduction in symptoms in patients treated with quercetin, due to its anti-inflammatory and antioxidant action.

In the field of oncology, quercetin is studied for its potential role in the prevention of prostate cancer, although it is not yet recommended as a specific treatment. However, its use as an adjunct in integrative protocols is promising.

Side effects and contraindications

Quercetin is generally well tolerated, but at high doses it can cause side effects such as nausea, headache or, rarely, kidney damage. It is not recommended when taking anticoagulant drugs, such as aspirin, or quinolone antibiotics, with which it may interact negatively.

It is always advisable to avoid prolonged use without a break and to consult a doctor before starting supplementation, especially in the presence of chronic diseases or drug therapies.

Quercetin is a valuable natural ally for prostate health, especially in cases of chronic inflammation. Its antioxidant and anti-inflammatory action is well documented, and dietary sources are readily available. However, supplementation must be carefully evaluated, taking into account bioavailability and possible drug interactions.

In the context of integrative and personalised medicine, quercetin may offer significant benefits, but it should not be considered a panacea. Research continues to explore its potential, and its role in cancer prevention may become increasingly relevant.

Champignon mushrooms and the prostate: a natural ally in prevention

,

Champignon mushrooms, also known as white mushrooms and scientifically called Agaricus bisporus, are among the most widespread and cultivated edible mushrooms in the world.

Appreciated for their delicate flavour and versatility in cooking, these mushrooms are attracting the attention of the scientific community for their potential role in preventing and slowing down the prostate cancer.

In recent years, several studies conducted by leading cancer research centres, such as the City of Hope in California, have shown that mushrooms contain bioactive compounds capable of positively influencing the immune system.

In particular, it has been observed that the regular consumption of these mushrooms is associated with a potentially lower risk of developing prostate cancer.

The mechanism behind this protective effect is related to the modulation of the immune response.

Certain compounds found in mushrooms, including β-glucans, appear to be able to reduce the number of a type of cell called myeloid suppressor cells (MDSCs), which normally promote tumour growth, and to activate T-cells and natural killer cells, which are essential for fighting cancer cells.

Promising data from research

The results are encouraging both in animal models and in preliminary clinical studies. In mice with prostate, champignon extract slowed tumour growth and improved survival.

In human patients, a phase 2 clinical trial showed that taking a mushroom-based supplement led to a reduction in MDSCs and an increase in anti-tumor immune cells, suggesting a potential biological effect whose clinical relevance is still under investigation (source).

Other nutritional benefits

Besides their potential role in cancer prevention, mushrooms are rich in fibre, protein, B vitamins (especially B2 and B3), potassium and selenium.

They are low in calories and fat, which makes them an ideal food even for those on a balanced diet or trying to lose weight.

In addition, they contain vitamin D, beneficial for bone and immune health, especially when exposed to UV light during cultivation.

Possible contraindications and precautions

Despite its many benefits, it is important to consume mushrooms with some precautions.

When raw, these mushrooms contain a substance called agaritin, a compound studied for possible toxicological effects in animal models, but without evidence of risk in humans; cooking significantly reduces its levels.

In addition, those who suffer from allergies or have a compromised immune system should consult their doctor before taking mushroom supplements, especially if involved in cancer treatment.

Champignon mushrooms, like other types of mushrooms, are an example of how a simple and common food can hide interesting therapeutic potential.

Although the research is still ongoing and further clinical confirmation is needed, the data collected so far indicate that integrating mushrooms into the diet could be a healthy choice, especially for men interested in prostate cancer prevention.

As always, it is good to remember that no food alone can replace an early diagnosis, a healthy lifestyle and regular medical monitoring.

But knowing that what we put on our plate can also make a difference is a powerful and encouraging message.

Bearberry and Prostate Health

, ,

Bearberry is a wild plant from mountainous and cold regions that has been known for centuries for its medicinal properties. Its botanical name is Arctostaphylos uva-ursi, and is mainly used in phytotherapy for the leaves, not the fruit.

These leaves, once dried, are used in herbal preparations to treat urinary tract disorders. Folk tradition and natural medicine have made it a valuable remedy, especially for urinary infections and, more recently, for certain problems related to the prostate.

Bearberry is traditionally used to treat urinary infections, but in recent years it has also attracted interest for its potential role in prostate health, particularly in the management of prostatitis bacteria.

Active Ingredients and Cellular Mechanisms

The therapeutic power of bearberry lies in its active ingredients, which act synergistically at the cellular level. The best known compound is arbutin, a glycoside that, when metabolised, releases hydroquinone, a substance with strong antibacterial activity. This mechanism is particularly useful against bacteria colonising the urinary tract and prostate.

In addition to arbutin, the plant contains tannins, flavonoids and phenolic acids, which help reduce inflammation, protect cells from oxidative stress and limit microbial proliferation. These effects translate into a beneficial action on irritated or infected tissues, helping to restore cell balance.

The active ingredients contained in the leaves, such as arbutin, are metabolised into hydroquinone, a substance with strong antibacterial activity. This compound is able to fight bacteria such as Escherichia coli, Staphylococcus aureus and Enterococcus faecalis, which are often involved in infections affecting the prostate.

A multi-centre clinical study known as BRUMI evaluated the efficacy of bearberry in acute uncomplicated cystitis, showing that the titrated dry extract may be non-inferior to fosfomycin in controlling urinary symptoms, with a good safety profile when used for short courses. Although the study focuses on cystitis, the mechanisms of action involved are also relevant for bacterial prostatitis, which often originates from ascending urinary infections.

With regard to benign prostatic hyperplasia (BPH), there are no direct clinical studies confirming the efficacy of bearberry in reducing prostate volume. However, it has been observed that chronic inflammation plays an important role in the progression of BPH, and bearberry, due to its tannins and flavonoids, may help modulate the inflammatory response. This anti-inflammatory effect may offer an indirect benefit in patients with irritative symptoms associated with BPH.

Bearberry and Treatable Prostate Diseases

Bearberry is particularly useful in the acute and chronic bacterial prostatitis, where the infection is sustained by hydroquinone-sensitive bacteria. In these cases, the antiseptic action of bearberry may help reduce the bacterial load and improve urinary symptoms. Preclinical evidence shows that hydroalcoholic extracts of the plant effectively inhibit the growth of uropathogenic bacteria, with minimum inhibitory concentrations ranging from 0.3 to 1.2 mg/mL.

A multi-centre clinical study known as BRUMI evaluated the efficacy of bearberry in acute uncomplicated cystitis, showing that the titrated dry extract may be non-inferior to fosfomycin in controlling urinary symptoms, with a good safety profile when used for short courses. Although the study focuses on cystitis, the mechanisms of action involved are also relevant for bacterial prostatitis, which often originates from ascending urinary infections.

For benign prostatic hyperplasia (BPH), bearberry is not considered a primary treatment, but can be used as adjuvant in the presence of inflammatory symptoms or recurrent urinary infections. Some phytotherapeutics, such as serenoa repens and pygeum africanum, are better studied for BPH, but bearberry can be integrated into combination phytotherapy protocols, especially in cases where prostate inflammation is associated with infections.

There are no direct clinical studies on BPH confirming the efficacy of bearberry in reducing prostate volume.

However, it has been observed that chronic inflammation plays an important role in the progression of BPH, and bearberry, due to its tannins and flavonoids, may help modulate the inflammatory response. This anti-inflammatory effect may offer an indirect benefit in patients with irritative symptoms associated with BPH.

Is it better a supplement or the whole plant?

The choice between supplements and whole plants depends on several factors, including convenience, dosage precision and the patient's personal philosophy.

Supplements offer a standardised form, with known concentrations of active ingredients, and are easier to take. The whole plant, in the form of dried leaves for infusions or decoctions, preserves the entire phytocomplex, but requires more care in preparation and dosage.

In general, for those seeking a controlled and safe approach, supplements are preferable. However, those who prefer traditional natural remedies may opt for the whole plant, as long as they follow the instructions of an expert.

Precautions and Contraindications

Despite its benefits, bearberry should be used with caution. Prolonged intake or high doses may cause side effects, such as gastrointestinal disturbances or impaired liver function. It is contraindicated in pregnancy, lactation, in children and in people with kidney or liver disease.

Treatment should be limited to short periods, generally not exceeding one week, unless otherwise medically indicated. As with any natural remedy, it is essential to avoid self-medication and to consult a professional before use.

Turmeric and Prostate: A Natural Treasure for Men's Health

, , , ,

Turmeric (Curcuma longa) is a spice used in Ayurvedic and Chinese medicine to treat numerous inflammatory conditions. Today, modern science confirms its therapeutic potential, particularly for the health of the prostate.

The Active Ingredient: Curcumin and Curcuminoids

The main bioactive compound in turmeric is the curcumin, a polyphenol with anti-inflammatory, antioxidant and immunomodulatory properties. It accounts for approximately 77% of the curcuminoids present in the rhizome of the plant. However, curcumin has a very low bioavailability, due to rapid hepatic and intestinal metabolism. To overcome this limitation, advanced formulations (with piperine, nanoemulsions, aerogels) have been developed that increase absorption up to 100 times.

Mechanisms of Action on the Prostate

Curcumin acts on several biological mechanisms. It inhibits the production of pro-inflammatory cytokines (TNF-α, IL-6), reduces oxidative stress and modulates cell signalling pathways such as NF-κB, Akt/mTOR and Ras/MAPK. These effects help slow the proliferation of cancer cells and promote apoptosis, i.e. the programmed death of diseased cells (source).

Prostatic Pathologies Involved

Benign prostatic hyperplasia (BPH)

Curcumin has been shown to improve urinary symptoms in patients with BPH. In a randomised clinical trial, 160 mg per day of curcumin for three months significantly reduced the’IPSS (International Prostate Symptom Score) and C-reactive protein levels.

Chronic Prostatitis

Although evidence is still limited, some studies suggest that curcumin may alleviate inflammation and the pelvic pain associated with the prostatitis chronic. However, European guidelines do not include it among the phytopharmaceuticals officially recommended for this condition (source).

Prostate Cancer

Numerous in vitro and in vivo studies have shown the effectiveness of curcumin in reducing the viability, proliferation and migration of prostate cancer. A meta-analysis in animal models confirmed the significant reduction in tumour volume and weight. Moreover, curcumin acts on both androgen-sensitive and androgen-insensitive tumours. (source).

Turmeric Supplements: Modes of Use and Safety

Curcumin supplements are available in capsules, tablets and powders. The most effective formulations include piperine or encapsulation technology to improve absorption. The recommended dosage varies between 500 mg and 2000 mg per day, divided into several doses.

Contraindications

Curcumin can interact with several drugs, including:

  • Anticoagulants (Warfarin, Aspirin): may increase the risk of bleeding.
  • Antidiabeticsmay potentiate the hypoglycaemic effect.
  • Antacidscan alter the production of gastric acid.

It is not recommended in cases of gallstones, active gastric ulcers and during pregnancy or lactation without medical supervision.

Turmeric, thanks to curcumin, offers promising natural support for prostate health. Its anti-inflammatory, antioxidant and anti-cancer effects are well documented, but do not replace medical therapies. Supplementation may be useful in a preventive or complementary context, always under medical supervision.

Pomegranate: a valuable fruit for the prostate

The pomegranate, with its bright red berries, has been a symbol of fertility, abundance and health for centuries. But in addition to its symbolic value and pleasantly tart taste, this fruit has also earned a place of honour in modern scientific research, thanks to its many beneficial properties for the body. In particular, the pomegranate is proving to be an important ally for the health of the prostate.

What pomegranate contains

The pomegranate is a fruit that is extraordinarily rich in beneficial substances. Besides its pleasant flavour, it contains a combination of nutrients and bioactive compounds that make it a true “superfruit”. In particular, it is known for its high content of antioxidants, especially polyphenols such as punicalagin and ellagic acid, which play a key role in protecting cells, including prostate cells.

Here are the main nutritional values per 100 grams of pomegranate arils:

ComponentQuantity per 100 g
Energy68 kcal
Total carbohydrates17,2 g
Sugars16,6 g
Protein0,95 g
Total fats0,3 g
Fibres0,6 g
Potassium259 mg
Vitamin C10.2 mg
Vitamin K16.4 µg
Folic acid (B9)38 µg
Total polyphenols*200-300 mg

*The amount of polyphenols may vary depending on the variety and ripeness of the fruit, but on average it is between 200 and 300 mg per 100 g of fresh arils

This combination of nutrients makes pomegranate particularly useful in fighting inflammation and oxidative stress, two key factors in prostate health.

How it acts on the prostate

The prostate is a gland that is very sensitive to the’inflammation and oxidative stress, two conditions that increase with age and can lead to disorders such as the’benign prostatic hyperplasia or, in more serious cases, to the tumor. Pomegranate polyphenols help reduce these risk factors by protecting prostate cells from damage and modulating the inflammatory response.

Studies have shown that regular consumption of pomegranate juice can slow down the increase of PSA, un marcatore importante per la salute prostatica, e persino inibire la crescita delle cellule tumorali. In particolare, si è osservato che il melograno può favorire l’apoptosi, ovvero la morte programmata delle cellule anomale.

Effects on hyperplasia and LUTS

A triple-blind clinical trial on 40 individuals evaluated pomegranate peel extract capsules in addition to tamsulosin for 4 months: at the end of the study, the pomegranate group showed an improvement in IPSS compared to placebo, with no significant changes in prostate volume or PSA (source); the study is small and requires independent, longer-term confirmation.

Effects on prostate cancer

In a 12-month placebo-controlled clinical study in 30 men under active surveillance, 1,000 mg/day of pomegranate extract did not alter PSA growth rate or biopsy results. However, a decrease in signs of oxidative damage and androgen receptor activity was observed in prostate tissue. Essentially, there are biological effects, but no measurable clinical benefit over one year (source).

In another study of 199 men, a combination supplement (Pomi-T: pomegranate + green tea + broccoli + turmeric) led to a smaller increase in PSA after 6 months compared to a placebo. However, since it is a mix of ingredients, we cannot attribute the effect to pomegranate alone, and PSA remains an indirect indicator, not a final clinical outcome (source).

How much pomegranate to take

To obtain real benefits, it is advisable to consume the fruit or its juice regularly. One glass of fresh juice per day (approx. 200-250 ml) is an amount generally considered effective and safe. Alternatively, dry extract supplements can be taken, provided they are standardised in polyphenols and under medical advice.

Are there any contraindications?

Pomegranate is well tolerated by most people, but it is not without contraindications. It may interact with some medications, particularly those for blood pressure or blood thinning. In addition, excessive consumption can cause gastrointestinal disturbances in sensitive individuals. For this reason, it is always advisable to discuss it with your doctor, especially if you are following drug therapies.

Incorporating pomegranate into your diet is a simple but powerful gesture. It is not a miracle cure, but a natural support that, if taken regularly and consciously, can contribute significantly to prostate health and general well-being. A small fruit, in short, with great potential.

Watermelon and the prostate: a summer fruit that is good for men

When we think of summer, watermelon is one of the first fruits that comes to mind: sweet, refreshing, and perfect for beating the heat. But few people know that this fruit may also offer benefits for prostate health, supported by scientific studies. prostate, supported by scientific studies.

Watermelon is more than 90% water, but it is not only a thirst-quenching fruit. Within it we find:

  • Lycopenea powerful antioxidant that gives the pulp its red colour. It is the same as that present in tomatoes, but in some varieties of watermelon it is even more concentrated.
  • Citrullinean amino acid that promotes blood circulation.
  • Vitamin Cuseful for the immune system and to fight inflammation.
  • Polyphenols and carotenoids: natural substances with antioxidant effects.
NutrientQuantity per 100 gMain benefits
Lycopene4-5 mgAntioxidant, protects prostate cells, reduces risk of prostate cancer
Citrulline40–160 mgImproves blood circulation, useful for urinary and sexual function
Vitamin C8.1 mgAnti-inflammatory, supports the immune system
Polyphenols1 mg GAEAntioxidants, counteracting oxidative stress
Total carotenoids5-7 mgAntioxidants, counteracting oxidative stress

Why is it good for the prostate?

Lycopene is the key player. It is an antioxidant carotenoid that has been studied for its possible role in prostate health. Some observational studies suggest an association between higher lycopene intake and a lower risk of prostate cancer, but direct clinical evidence remains inconclusive (source).

Lycopene has antioxidant properties, and in experimental models and intervention studies it has been associated with effects on oxidative stress, inflammation, and proliferative signaling.

The citrulline found in watermelon is involved in nitric oxide metabolism and may support general vascular function; however, there is not enough evidence to claim that watermelon directly improves urinary symptoms or sexual function related to the prostate (source).

Watermelon, thanks to vitamin C and other antioxidants, can help reduce chronic inflammation, which is often present in cases of benign prostatic hyperplasia (BPH), a very common condition in men over 50.

Are there any contraindications?

In general, watermelon is safe and well tolerated. However, care should be taken in some cases:

  • Those with high blood sugar or diabetes problems should consume it in moderation, as it contains natural sugars.
  • In people with advanced kidney disease or those on a potassium-restricted diet, portion sizes should be discussed with a nephrologist or dietitian.
  • Some people may have mild allergic reactions, especially if they are already sensitive to other fruits.

Watermelon is not only good: it is also a functional fruit that can help protect the prostate and improve male health naturally. Including it in your summer diet is a tasty and smart choice, especially when accompanied by a healthy lifestyle.

However, precisely because of its very high water content, it is important to be careful when consuming it, especially for those who suffer from nocturnal urinary disorders.

Eating plenty of watermelon in the evening can increase the frequency of urination at night, disturbing sleep and worsening quality of life. In such cases, it is advisable to eat it preferably during the day, when the body is more active and can better manage water intake.
