Doctor Answers: Prostatitis Diet: What Foods To Eat and Avoid?

If you’re looking into the link between diet and prostatitis, you’re not alone. Prostatitis is the general term for inflammation of the prostate and can affect men of all ages, though it’s especially common in men aged 30 to 50. We spoke with Dr. Letsa, who has provided a comprehensive collection of research and evidence for this article, to discuss how certain foods might help or aggravate prostatitis.

During our interview, Dr. Letsa offered valuable insights on the role of prostatitis diet, lifestyle factors, and potential treatment strategies. Additionally, all content has been thoroughly reviewed by a medical doctor to ensure accuracy and reliability.

Q: What Is Prostatitis?

Dr. Letsa answers: Prostatitis is a clinical condition comprising a spectrum of inflammatory diseases of the prostate gland. Acute bacterial, persistent bacterial, chronic pelvic pain syndrome (CP/CPPS), and silent inflammatory prostatitis are four forms it falls into.

Though their genesis, clinical presentation, and treatment vary, these kinds can all cause pelvic pain, lower urinary tract symptoms (LUTS), or ejaculatory discomfort. Appropriate diagnosis and treatment depend on an awareness of the particular subtype.

Q: What are the Types of Prostatitis?

Dr. Letsa answers: There are four main types of prostatitis:

• Acute prostatitis
• Chronic bacterial prostatitis
• Chronic pelvic pain syndrome (CP/CPPS)
• Asymptomatic prostatitis

Acute bacterial prostatitis presents with fever, chills, and perineal pain usually caused by gram-negative organisms like E. coli. Recurrent urinary tract infections marked by sporadic symptoms define chronic bacterial prostatitis.

Although it accounts for 90–95% of prostatitis diagnoses, CP/CPPS—which is not linked to infection—involves complex pathogenesis involving neurogenic inflammation, immunological dysregulation, and pelvic floor dysfunction. Usually found incidentally on biopsy or during fertility tests, asymptomatic inflammatory prostatitis does not call for therapy.

Determining which type of prostatitis you have is key to finding the cause and best treatment plan. For acute bacterial prostatitis caused by a bacterial infection, a doctor usually prescribes antibiotics. Bacterial infection also contributes to chronic bacterial prostatitis, commonly seen in men with frequent UTIs (urinary tract infections).

However, emerging research suggests that certain dietary adjustments may also offer benefits, especially for chronic forms.

Q: What are the Symptoms of Prostatitis?

Dr. Letsa answers: The severity of prostatitis symptoms can vary depending on the type. Common symptoms include:

• Difficulty urinating or frequent urination, sometimes accompanied by pain or a burning sensation
• Blood in the urine or cloudy urine
• Pain in the abdomen, groin, or lower back
• Pain in the area between the scrotum and rectum (the perineum)
• Discomfort or pain in the penis or testicles
• Pelvic pain
• Fever, chills, body aches, or flu-like symptoms
• Urethral discharge
• Burning after ejaculation or sexual dysfunction
• Pain during sexual intercourse

Acute urinary retention, sepsis (fever >38.5°C, hypotension), or hematuria with systemic signs calls for immediate urological evaluation and parenteral antibiotics.”

Chronic forms may show waxing and waning symptoms, including perineal pain, urine frequency, or painful ejaculation. Moreover, contributing to psychological discomfort is chronic pelvic pain, which calls for a multimodal treatment approach.

If you notice any of these symptoms, consult a urologist to determine the type of prostatitis and the most appropriate course of treatment.

Q: How Does Diet Affect Prostatitis?

Dr. Letsa answers: Diet is the cornerstone of overall health, and while there isn’t a one-size-fits-all diet specifically for prostatitis, research strongly suggests certain foods and drinks can trigger or worsen symptoms.

A study in Infectious Diseases in Clinical Practice reviewed 2,385 patients—1,710 men and 675 women—who all had prostatitis or urethral syndrome symptoms. These individuals followed a strict diet that excluded caffeine, alcohol, and spicy foods for 12 weeks. Remarkably, 87% of men and 89% of women reported substantial symptom relief after 12 weeks purely through dietary changes.

Similarly, a 2013 study in the Journal of Urology found that about half of the 95 CP/CPPS patients surveyed had worse symptoms when they consumed spicy foods, coffee, tea, or alcoholic beverages. Conversely, water, herbal teas, fiber, and stool softeners helped alleviate symptoms. It’s also widely recommended to drink plenty of fluids and consume a high-fiber diet—fruits, vegetables, and whole grains—to manage constipation and support prostate health.

​While no universally accepted diet has been established for managing chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), research indicates that certain dietary factors may influence symptom severity:​

• Dietary Irritants: Consumption of spicy foods, coffee, and alcoholic beverages has been reported to exacerbate pelvic discomfort in CP/CPPS patients. A study published in The Journal of Urology found that 47.4% of respondents identified specific foods and beverages that aggravated their symptoms, with spicy foods, coffee, hot peppers, alcoholic beverages, tea, and chili being the most common triggers.
• Constipation and Pelvic Pain: Addressing constipation is crucial, as it can worsen pelvic pain associated with CP/CPPS. Increasing dietary fiber intake has been shown to be an effective method for preventing and treating constipation. ​
• Dietary Patterns: Adopting dietary patterns with anti-inflammatory properties, such as the Mediterranean diet, may offer symptomatic relief for CP/CPPS patients. These diets are rich in fruits, vegetables, whole grains, and healthy fats, which can help reduce systemic inflammation.​

The mechanisms by which these dietary factors influence CP/CPPS symptoms may involve modulation of inflammatory cytokines and visceral hypersensitivity. However, individual responses can vary, and it is advisable for patients to monitor their own symptoms in relation to specific dietary habits.

Another, more recent study looked at both diet and lifestyle in 784 men with chronic prostatitis/pelvic pain syndrome. It identified several risk factors:

• Older age
• Night shift work
• Stress
• Smoking
• Alcohol consumption
• Low water intake
• An imbalanced diet
• Delaying ejaculation
• Holding urine

Additionally, the study linked a sedentary lifestyle, caffeinated drinks, and low water intake with greater severity of pain in patients with chronic prostatitis. This research highlights the potential impact of daily habits—including what you eat and drink—on your prostate health.

Q: Which Foods Should You Include in a Prostatitis Diet?

Dr. Letsa answers:  A well-rounded diet abundant in fruits, vegetables, and healthy fats can support prostate health. Some important additions to consider:

Fiber-rich foods, to help prevent constipation. Constipation can be particularly painful if you have an inflamed prostate., and low water intake link with severe pain in patients with chronic prostatitis.

Cruciferous vegetables (like broccoli and cauliflower). They contain beta-carotene and offer anti-inflammatory effects that could help with various prostate issues, including prostate cancer and benign prostatic hyperplasia (BPH).

Fruits, especially berries, for their high antioxidant content, vitamins, and minerals. However, if acidic citrus fruits worsen your symptoms, avoid or limit them.

1.5 to 2 liters of water per day to stay well-hydrated.

Herbal teas, especially green tea, which studies suggest may improve urine flow and reduce urological inflammation.

High-quality protein sources (e.g., lean meats, eggs, legumes).

Omega-3 fatty acids (from sources like fatty fish, flaxseed) and healthy fats (such as extra-virgin olive oil), commonly found in the Mediterranean diet. These can fight inflammation.

Tomatoes, which contain lycopene—an antioxidant that may protect prostate cells.

Encourage water intake (1.5–2.5 L/day) and high-fiber foods to mitigate constipation, which can worsen pelvic floor strain. Indole-3-carbinol and sulforaphane abound in cruciferous vegetables, including broccoli, kale, and Brussels sprouts, which may have possible anti-inflammatory and chemoprotective effects.

Zinc has been investigated for its function in prostatic tissue healing and immunomodulation; randomized controlled studies are conflicting. Assess serum zinc levels before prescribing supplements. Though its exact function in prostatitis especially remains theoretical, tomatoes are high in lycopene, a carotenoid with possible antioxidative effects for prostate health.

Q: Which Foods Should You Avoid in a Prostatitis Diet?

Dr. Letsa answers:  It’s essential to identify which foods irritate your own symptoms. While each person’s triggers can be different, the following are commonly problematic:

• Caffeine (coffee, tea, energy drinks)
• Alcohol (beer, wine, liquor)
• Spicy foods (they can contain capsaicin, which may heighten rectal sensitivity, especially in individuals with irritable bowel syndrome)
• High sodium intake, which can worsen urinary tract symptoms linked to prostate disease
• Gluten (if you have an intolerance or sensitivity, it can cause inflammation and potentially aggravate prostatitis)

Pay attention to how your body responds after consuming these foods. Eliminating or reducing them could help manage symptoms more effectively.

Avoid or restrict recognized urinary tract irritants, including coffee, alcohol, spicy foods (particularly those heavy in capsaicin), and high-sodium processed meals. Although some patients claim their symptoms get worse after eating gluten, this is only clinically valid in those with gluten sensitivity or celiac disease.

Emphasizing a personalized diet, keeping a thorough food-and-symptom record for two to three weeks will help one find particular triggers. It is imperative to teach patients to separate food reactions between correlation and causation.

Q: Can You Give a Sample Meal Plan for Prostatitis Management?

Dr. Letsa answers: There are many options for adopting a diet for prostatitis. You can be a meat eater, vegetarian, or follow other special diets and still include foods that are good for your prostate and overall health. The most important aspects of a prostatitis diet are avoiding your triggers (these can vary from person to person), including nutrient-rich and anti-inflammatory foods, and minimizing foods that promote inflammation, as discussed earlier.

Here is an example of a one-day sample meal plan for prostatitis (it’s assumed that you’re drinking adequate amounts of water to avoid dark, concentrated urine with a strong odor):

Breakfast:

• ½ cup dry oats, cooked with water
• 1 cup blueberries, fresh or frozen
• 1 ounce slivered almonds to top oatmeal
• Two scrambled eggs (can add sliced avocados or a handful of shredded cheese if desired)
• Optional: Brewed green tea 

Lunch:

• Shredded skinless chicken breast (around 4 ounces) sandwich on 2 slices of whole wheat bread
  • Add ½ sliced avocado, 2 Swiss cheese slices (lower sodium than cheddar), and/or 2 tbsp. Mayonnaise to enhance flavor)
• 1 cup baby carrots
• Sliced strawberries on 1 cup plain Greek yogurt; add a drizzle of honey if desired

Dinner:

• 4 oz. salmon fillet, baked with lemon juice drizzled on top
• 1 cup cooked brown rice, seasoned to taste with a pat of butter and salt
• Half a plate of roasted asparagus (tossed in olive oil and a pinch of salt before cooking in a skillet)

Snack ideas:

• Fresh fruit or vegetables
• Low-sugar Greek yogurt
• Hard-boiled eggs
• Mozzarella cheese sticks
• Nuts
• Dark chocolate (minimum 70% cacao)

Although the presented strategy follows anti-inflammatory guidelines, individual tolerances and comorbidities (such as diabetes, hypertension, and IBD) have to be taken into account. Long-term sustainability is indicated to be achieved by cooperation with a trained nutritionist. Whole foods, lean protein, unsaturated fats, and enough water should all take front stage in a well-balanced diet.

Q: What Are the Treatment Options for Prostatitis?

Dr. Letsa answers:  Prostate infections can indeed lead to unpleasant or even debilitating discomfort. Fortunately, several effective treatments exist—ranging from medical interventions to natural remedies and lifestyle changes.

Medication

For bacterial prostatitis, doctors typically prescribe antibiotics for at least three to four weeks. If you have non-bacterial chronic prostatitis, nonsteroidal anti-inflammatory drugs (NSAIDs), alpha-blockers, and alternative remedies can offer relief.

Natural Alternatives

Many men find that certain natural supplements and substances help reduce inflammation and pain, such as:

• Quercetin: One double-blind study showed this flavonoid could lessen pelvic floor pain.
• Bee pollen: Has nutritional and antimicrobial properties that may ease prostate inflammation.
• Saw palmetto: Known for its potent anti-inflammatory effects and may help treat prostatitis.
• Pollen extract: Some patients in clinical studies reported better symptom improvement with pollen extract for chronic non-bacterial prostatitis.

Exercise

Maintaining an active lifestyle can help you keep a healthy weight and support overall well-being. Specifically, aerobic prostatitis exercises have been shown to alleviate prostatitis symptoms.

In one study, 231 men with prostatitis were assigned to exercise three times weekly for 18 weeks. One group did aerobic exercises, while the other engaged in non-aerobic routines. Both sets of participants felt better over time, but those who did aerobic exercise experienced significantly more improvement in chronic pelvic pain syndrome (CPPS) pain levels, as well as reduced anxiety and depression.

Additionally, pelvic floor exercises can help men struggling with urinary symptoms by strengthening the muscles around the bladder and prostate.

For verified bacterial types, antibiotic therapy is indicated. Commonly utilized in CP/CPPS is multimodal treatment comprising alpha-blockers, NSAIDs, phytotherapy (e.g., quercetin, pollen extract), and stress reduction. Supported by many studies demonstrating a decrease in pelvic muscle tension and dyssynergia, pelvic floor physical therapy is a pillar intervention for CP/CPPS. Supplements should be administered under medical control and not substitute guideline-based treatment.

Key Patient Questions on Diet for Prostatitis

Q: Can fasting or intermittent fasting help with prostatitis?

Dr. Letsa answers: Intermittent fasting has become a popular eating pattern, especially in the last decade. There are many studies on the effects intermittent fasting may have on your health. One such study summarized some of the most significant benefits: a reduction in body weight, improvements in blood pressure levels, and an improvement in blood lipid levels.

There aren’t many direct studies looking at the relationship between intermittent fasting and the potential effects on the prostate, specifically prostatitis. However, one small study of 14 middle-aged healthy men found that eight days of fasting (only consuming water) improved lower urinary tract symptoms, which can be caused by prostatitis among other urinary conditions. 

Another study found that longer periods of nighttime fasting lowered the risk of prostate cancer. Since inflammation (such as prostatitis) increases prostate cancer risk, it’s reasonable to assume there may be some benefits of fasting to help with prostatitis.

There are several methods of intermittent fasting which vary in the time fasted per day, and even which days of the week you fast. In general, 12 hours is the minimum time needed to achieve a “fasting state”, which is when the potentially beneficial metabolic changes occur.

The bottom line: intermittent fasting may help with prostatitis. If you’re thinking of trying intermittent fasting, be sure to talk with your healthcare provider first, since some people aren’t good candidates (e.g. on insulin therapy, chronic low blood sugar, etc). Although intermittent fasting lowers systemic inflammation and enhances metabolic indicators, its direct effect on prostatitis is yet hypothetical. There aren’t any clinical studies assessing intermittent fasting in CP/CPPS populations.

Q: Can probiotics play a role in managing prostatitis symptoms?

Dr. Letsa answers: Probiotics are strains of bacteria that are considered good for your health, unlike harmful bacteria that cause illness and infections. Probiotics may help reduce your risk of infection by supporting your immune system. Particularly strains like Lactobacillus casei or L. rhamnosus, post-antibiotic probiotic treatment has demonstrated only minimal effect in immunological restoration and decrease of symptom recurrence. Defining length, strains, and results calls for larger RCTs. After antibiotic treatment, probiotics could help the urogenital bacteria to be rebalanced.

The term microbiota refers to the bacteria that primarily reside in the human digestive tract, but can also reside in your mouth and urinary tract. Unfortunately, many modern medical treatments and lifestyle habits can reduce your body’s microbiota, such as the use of antibiotic drugs (the kind used to treat bacterial prostatitis), a diet low in fiber (fiber feeds the good bacteria in your digestive tract), stress, activity level, and many other factors.

Probiotics are found naturally in fermented foods but are also isolated and utilized in probiotic supplements. Some examples of foods naturally rich in probiotics include:

• Yogurt
• Kefir (a more liquid version of yogurt that can be drank)
• Sauerkraut 
• Tempeh (fermented soybeans; often used as a protein source in vegetarian and vegan diets)
• Kimchi (a traditional Korean dish consisting of fermented vegetables such as cabbage)
• Miso (a paste made of fermented soybeans and kōji, a type of mold used for fermentation that is safe to consume)

A 2025 study looked at the effects probiotics had on men with chronic prostatitis. The study found that supplementation with a probiotic supplement containing Lactobacillus casei after test subjects were treated for chronic prostatitis (using an antibiotic) reduced the days of symptoms compared to the group that received a placebo after prostatitis treatment. The group receiving the probiotic also had lower levels of other types of bacteria that can cause bacterial prostatitis, such as Pseudomonas.

Q: How long should I try a specific diet plan before deciding it’s effective?

Dr. Letsa answers: Waiting for results after adopting a new diet or eating style can be frustrating. According to ABC News, a survey from the UK in 2013 found that 2 out of 5 people adopting a new diet stopped the diet within seven days, and only about 20% of dieters make it three months with their new eating habits.

The main reason people end up quitting so early is that their diets are unsustainable – they’re too strict, include eating foods you might not like, or cut out enjoyable foods, to name a few reasons. It’s also easy to get discouraged if you don’t see results immediately, or even after a week or so.

If you try a specific diet plan for prostatitis, the changes you plan to make must be realistic and sustainable. If your goal is to reduce your sodium intake, focus on reducing your current sodium intake instead of aiming to cut out salt altogether. 

In the study on probiotics for prostatitis (cited earlier), the duration of the use of probiotics was three months before researchers analyzed the results. If you suffer from chronic prostatitis, you should give yourself around three months to assess if a particular diet is working. If your symptoms are noticeably worsening after adopting a new diet, then you should discontinue the diet immediately and speak with your healthcare provider.

Three months isn’t a magic, one-size-fits-all time frame, but most people will start to notice differences, even subtle ones, within that period. You might even notice changes within weeks depending on how different your new diet is from your old eating habits!

Three months is a reasonable trial time to examine nutritional efficacy. Still, one could see some modest changes in weeks. Tracking can be improved by ongoing observation with validated symptom scores—e.g., NIH-CPSI.

Q: Is coffee bad for prostatitis?

Dr. Letsa answers: Caffeine increases urine urgency and frequency by functioning as a bladder stimulant and diuretic. In sensitive people, these consequences could aggravate LUTS. Perhaps better tolerated are decaffeinated choices. Experimentation led by patients with less caffeine use is advised.

Other than potentially worsening prostatitis symptoms due to caffeine, coffee isn’t considered bad for urinary health. In fact, studies show a correlation between coffee intake and reduced prostate cancer risk. Interestingly, drinking coffee was associated with a significant reduction in deadly types of prostate cancer, according to one study.

According to that same study, similar benefits were found among men who consumed decaffeinated coffee. This means that with or without caffeine, coffee may be good for your prostate. The reason may be due to the antioxidants found in decaffeinated coffee, notably chlorogenic acid.

If you have acute prostatitis, it’s best to lay off caffeinated beverages (including coffee) until your symptoms improve. If you’re dealing with chronic prostatitis, you might consider speaking with your healthcare provider about trying decaffeinated coffee in moderation if you struggle to avoid coffee.

Alternatively, if you don’t drink large amounts of coffee, you might be able to tolerate one cup a day without impacting urinary symptoms. It might be a bit of a trial-and-error process, but you’ll likely find your sweet spot for coffee intake, whether that means strictly avoiding it or opting for decaf. 

The bottom line: as long as you’re not drinking enough regular coffee to significantly increase urine output and worsen your symptoms, you might not need to avoid it altogether.

Q: Do men with prostatitis need to avoid all spicy foods or just certain types?

Dr. Letsa answers: Spicy foods get their spice from a compound called capsaicin, which is found in all types of chili peppers. It doesn’t matter what type of spicy food you eat – the spice is likely from peppers high in capsaicin (hot sauce, crushed red peppers, pickled jalapenos, etc). 

The higher the capsaicin content of the pepper, the spicier the food will be. That’s why there are varying levels of spice in things like hot sauce and salsa – the spiciest foods contain peppers like habaneros, while milder peppers include bell peppers, poblano peppers, and banana peppers.

Capsaicin activates TRPV1 receptors in the bladder and prostate, therefore perhaps increasing urgency or pelvic pain even if it has anti-inflammatory effects. Tolerance is quite different. Low-capsaicin meals should be gradually reintroduced to help ascertain appropriate consumption limits.

Spicy foods might irritate your bladder and worsen prostatitis in some people. According to a study, spicy foods were a notable trigger for around half the people with chronic prostatitis who completed a survey on food and beverage triggers (a total of 95 people completed the survey, which is considered small in terms of studies). 

Similar to coffee, several studies show that capsaicin in spicy foods is beneficial for reducing inflammation in the prostate, helping to reduce prostate cancer risk (remember that chronic prostatitis is a risk factor for prostate cancer).

For more of a long-term plan for chronic prostatitis, you might consider trying lower-spice pepper products (if desired) and assess your symptoms from there. If you eat spicier food and don’t notice any worsening of your symptoms, then you can likely include it in your diet in moderation – especially considering the long-term benefits capsaicin may have on prostate health. As always, follow the guidance from your healthcare provider above anything else, and listen to your body to find what works for you.

Conclusion

While prostatitis is not life-threatening, its symptoms can be intense and disruptive. If you notice any of the signs we discussed—such as painful urination, pelvic pain, or persistent discomfort—schedule a visit with your urologist. Determining the type of prostatitis you have is vital for figuring out the best treatment plan and prostatitis diet.

In many cases, a comprehensive strategy that includes antibiotic treatment (when bacterial infection is present), natural alternatives, and targeted lifestyle changes—particularly dietary modifications—can significantly relieve symptoms. Always consult a healthcare professional for personalized advice and management.
