Nutrition and Prostate Cancer in Men

Nutrition and Prostate Cancer in Men

Prostate cancer is the most common cancer occurring in men. Although researchers are not absolutely sure what causes prostate cancer, diet is considered a possible risk factor in its development.

A diet containing three ounces or three servings per day of whole walnuts may slow down the growth of prostate tumors, according to a study published in the British Journal of Nutrition. The rate of prostate tumor growth was 28 percent lower in walnut-fed experimental animals compared to the other groups fed on soybean oil and low fat diet, respectively.


Lycopene, vitamin E and selenium are also thought to reduce the disease risk, however, the Academy of Nutrition and Dietetics suggests getting them from foods rather than supplements. "While these minerals may not eliminate the risk of prostate cancer, their consumption contributes to overall health and that may be the best defense against any and all cancers," says Jim White, the spokesperson of this organization.

Researchers also believe that diets high in calcium, that is, above 1500mg per day may increase prostate cancer risk. According to the American Institute for Cancer Research, 'avoiding excessive amounts of milk and high doses of calcium is suggested, but moderate amounts of dairy and total calcium no more than 1500mg daily are considered safe'.

Aim to eat two and a half cups of vegetables and two cups of fruit per day (one serving less for men over 50). Dark-colored fruits and vegetables like spinach, berries, and orange bell peppers, have higher levels of many carotenoids. Although these nutrients may not prevent prostate cancer individually when obtained from foods, they work with one another to promote health.

Obesity increases risk of prostate cancer. So cut down on processed foods, energy dense foods, sugary drinks, and alcohol. Choose olive oil, canola oil, avocados, fish, and other healthy fats over saturated and trans fats.

Ultimately, the best way to maintain a healthy weight or prevent diseases is to eat smart and exercise more. Consult a registered dietician for a personalized diet plan.
