Good dietary practices used to prevent prostate cancer

Many good dietary practices used to prevent prostate cancer should also form part of the lifestyle of men who already have the condition. Many of these foods have been shown to lower prostate specific antigen (PSA), a marker of prostate cancer progression. This is an imperfect marker, however, and cannot always be conclusive evidence for prostate cancer survival. Some studies suggest that a diet rich in lycopene supplement of 15 mg (one cup tomato juice has 22 mg) can slow progression or recurrence of prostate cancer and improve survival, others have not found that association.

A few studies have also shown that whole soy products such as tofu and soy bean can lower PSA while others have shown conflicting results.

Soy and flaxseed
Ground flaxseed was shown to slow the progression of prostate cancer in a group of men awaiting surgery (Demark-Wahenfried et al, 2008). The same concern that exists for women with hormone-related cancers and plant-type oestrogen-like factors in soy and other foods such as flax, does not appear to have a similar effect on prostate cancer.

In addition, to the recommendation of continuing to consume a healthful diet from all food groups, with emphasis on plant-based and whole foods, many men will experience side effects of treatment which can affect intake. Treatment can also cause weight gain, muscle loss and even bone loss. It is recommended that a nutrition professional such as a registered dietitian or nutritionist be an integral part of the management team to assist the patient in managing these side effects.
Take 1500mg of calcium

Men on long-term hormone therapy can experience bone loss leading to osteoporosis. Their diet should be rich in vitamin D and calcium. Men over 50 years old should have a daily intake of 1,500mg calcium from all sources including food and supplement and should not exceed 2,500mg. A daily supplement of 1000 IU vitamin D is recommended and should not exceed 2,000 IU per day or 50 micrograms.

Adequate good quality protein is essential to prevent muscle loss and excess increase in fat. Physical activity is also important. A team effort with family and medical management team is important to help the patient deal with treatment side effects. Many will include gastrointestinal, such as diarrhoea, nausea, reduced appetite and even hot flashes, as a result of therapy. A healthy, nutritious diet is an effective weapon for successful management.
