Nutrition for a Healthy Prostate

by | Last updated Oct 2, 2023 | Cancer

Good, wholesome nutrition affords serious protection from prostate cancer. Prostate cancer is the most common non-skin cancer of men. The number of younger men diagnosed with prostate cancer has increased nearly 6-fold in the last 20 years and the disease is more likely to be aggressive in these younger men.1 A boy being born today has an almost 1 in 7 chance of developing prostate cancer at some point in his life.2 Prostate cancer is the second leading cause of death in elderly men. How can you or the man in your life reduce his risk? Women often do have a part to play as they cook for the men in their lives.

Dietary Risk Factors


Harvard University research showed that even one glass of cow’s milk per meal can increase the risk for metastatic cancer of the prostate by 40%.3 One serving of meat per meal increased the risk by 60% and both together synergized to raise the risk up to 200%. This basic finding has been confirmed from France, Australia, and Spain.4,5

Other negative nutritional factors like obesity, meat-fat intake, and lack of vitamins and trace elements may also be involved in initiation, growth, and spread of this cancer. One study found that men who had the highest body mass index and blood pressure had a 36% and 62% risk of dying from prostate cancer compared to those who had blood pressure within normal range.6

High Fat Diet

By activating a protein complex (NF- kappa B, that triggers inflammation), a high fat diet can cause cells in the prostate to proliferate and encourage inflammation there. A high fat diet also increases free radical damage. All three of these conditions can lead to an enlarged prostate, inflammation, and cancer of the prostate. 7


Obesity increases the risk for aggressive prostate disease. The fat surrounding the prostate of overweight or obese men with prostate cancer provides a favorable environment that encourages cancer growth. 8

Low Vitamin D Levels

Vitamin D deficiency is common in individuals with various cancers.9 Prostate cancer has been linked to vitamin D deficiency.10  Taking vitamin D supplements could slow or even reverse the progression of less aggressive, or low-grade, prostate cancer.11

Nutrition Is Vital After Diagnosis

Men, with the diagnosis of prostate cancer, who persisted in eating mostly a Western diet (high in red and processed meats, dairy fats, refined grains, and desserts) had two and half times the risk of dying from prostate-cancer related problems than those who ate a prudent diet consisting of more vegetables, fruits, whole grains, healthy fats, and fish.12

That is not all. The same study showed that the men who partook of the Western diet increased their risk of dying from any cause by 67% while those who ate the more prudent diet reduced their all-cause mortality risk by 36%.13

Delicious Defenses

Ditch Dairy Milk

The good news is that Loma Linda research showed that one glass of soy milk reduces cancer of the prostate by 200% even after adjusting for statistical cofounders.14

Enjoy Lycopene-Rich Foods

Tomatoes, strawberries, and watermelon all contain the cancer-protective phytochemical lycopene. Men who eat 10 servings of tomatoes per week seem to reduce their risk for developing prostate cancer by 18%. 15 Eating soy with tomato seems to provide even greater protection.16

Walnuts and Fleaxseeds

Early evidence indicates that regular consumption of walnuts may protect against prostate cancer.17 Omega 3-fats may inhibit the growth and spread of prostate cancer.18 Animal studies suggest that incorporating groundflaxseed inhibit the growth and progression of prostate cancer.19 Please note flax oil does not help.

Cruciferous Vegetables

Three or more servings per week, compared to less than one serving of cruciferous vegetables per week resulted in a statistically significant 41% decrease in prostate cancer risk.20

Beans and Peas

Rodent studies show that inositol hexaphosphate (also known as IP6 or phytic acid) may help to control the progression of prostate cancer in its early development. These phytochemicals prevented prostate tumors from making new blood vessels needed to feed the tumor. It also slowed the rate at which the tumors metabolized glucose.21 Wheat bran, whole grains, peanuts, black beans, chick peas, and mung beans are good sources of this phytochemical.

More Suggestions

Prostate cancer has an almost 100% survival rate if caught early enough. So, men, keep up with your annual physical. If you are a smoker, give it up. There is a direct effect of smoking on the progression of prostate cancer.22
