Health officials’ recommendations for the prostate are to eat food included a lots of fresh vegetables and fruits, legumes (peas, beans, and lentils) and fresh fish.
Fish contains essential fatty acids the body uses to produce prostaglandins, which keep the immune system strong.

Eat whole grain in moderation, rather than refined, and choose organically grown foods whenever it’s possible. 
It was found that gamma-tocopherol contained in walnuts, sesame seeds and corn holds back the proliferation of lab-cultured human prostate and lung cancer cells.
In medical studies there are suggestions that higher consumption of vitamin E and selenium lower prostate cancer risk. Vitamin E is found in basic plant foods, including nuts, vegetables, vegetable oils, as well as egg yolks.
Vitamin E is also in most breakfast cereals because it is added when manufacturers fortify it. The metallic trace element selenium comes into plants from the soil, so it’s in grains such as wheat, barley, hops, and rice.

There is also some selenium from animal foods products, because the food animals also consume this grain.

Of course any dietary change must be discussed with your doctor to find the most suitable diet that fit your body best – Online Medical Advice

There is also growing evidence that both tomato and broccoli consumption helps considerably reduce risk of prostate cancer. In the tomato products, attention has focused on nutrients called carotenoids, particularly lycopene. Lycopene is the major red carotenoid pigment found in tomatoes. In broccoli, a number of sulfur compounds are thought to detoxify carcinogens.

Both of these are thought to benefit prostate health. Carotenoids are very poorly absorbed from raw foods, so some heating really helps bring out the benefits. Consumption with a little healthy fat helps, too. For example take beta-carotene from carrots.     Eating carrot raw leads to 1 or 2 percent beta-carotene absorption.
Steaming those carrots a little bit and add a little bit of oil in there, you’ll get much more absorption of the beneficial carotenoids.

The same is true for tomatoes. By overcooking tomatoes, for example, by simmering a tomato sauce for hours, you’ll begin to break down the lycopene.
Nutrients in foods can lower risk of prostate cancer. In observational studies and clinical trials there are suggestions that higher consumption of vitamin E and selenium lower prostate cancer risk. Vitamin E is found in basic plant foods, including nuts, vegetables, vegetable oils, as well as egg yolks.
Vitamin E is also in most breakfast cereals because it is added when manufacturers fortify it.
