Maximize fruit and vegetables: Fruits and vegetables contain high levels of antioxidants, polyphenols, vitamins, minerals, and fiber, which can help fight infections, inflammation and contribute to overall health. Poor general health is a risk factor for prostatitis, and fruits and vegetables are an antidote. 

 
Consider a wheat-free diet: Although you won’t find any published studies on the topic of a wheat-free diet and prostatitis (at least not yet), there are anecdotal reports from men who have eliminated wheat products from their diet and who then experienced significant reduction or even elimination of prostatitis symptoms.
 
Choose plant protein over animal protein: Plant protein gives you all the nutrients and health benefits needed for prostatitis prevention. Diets rich in plant protein have been shown to reduce rates of prostate disease.
 
Consume green tea: Green tea contains substances called catechins that have potent antioxidant and anti-inflammatory properties. Research indicates that these catechins can be helpful in reducing infection and prostatitis prevention.
 
Try probiotics: Probiotics or beneficial bacteria, may be an effective addition to antibiotic therapy for men who have bacterial prostatitis and are looking for natural prostatititis prevention.
 
Eat healthy fats: A low-fat diet that includes healthy fats (omega-3s, monounsaturated) promotes prostate health, while a high-fat diet activates a protein complex that promotes inflammation.
 
Soy products: They can help prevent prostate enlargement and may slow tumour growth. This effect is attributed to isoflavones, plant chemicals that help lower dihydrotestosterone (DHT), a male hormone that stimulates the overgrowth of prostate tissue.
 
Selenium: selenium is another mineral that may offer protection. This antioxidant is found in nuts—especially Brazil nuts—seafood, some meats, fish, wheat bran, wheat germ, oats and brown rice.
 
Take the right supplements: Several supplements are helpful in prostatitis prevention if you have prostatitis, including Vitamin D, Zinc and Green tea extract. 
 
Avoid foods and additives that are harmful to prostate health: Some foods, supplements, additives and nutrients are especially harmful to the prostate, including but not limited to meat, calcium, chondroitin, and foods high in sugar. 
 
Warm tips: Prostatitis dietary therapy is only the adjuvant treatment for the patient. If patients want to cure prostatitis radically, they can take the herbal medicine diuretic and anti-inflammatory pill to get a cure.
