Prostate cancer and nutrition

Can certain foods help?

Much has been written about prostate cancer and nutrition, but researchers really don’t completely understand what role a man’s diet plays in the development or progression of prostate cancer.

The risk of prostate cancer appears to be slightly higher in men who:

  • Eat a lot of red meat
  • Maintain a diet that includes a lot of high-fat dairy foods
  • Eat few fruits and vegetables

The American Cancer Society recommends eating at least two and half cups of fruits and vegetables each day.

Men are also encouraged to choose the following foods:

  • Whole grain breads
  • Rices
  • Pastas
  • Cereals

Weight and activity

Men should also be physically active and maintain a weight that is healthy for them.  Ask the doctor what that means for your loved one. 

It's also good for men to maintain a healthy body mass index (BMI), which is a measure of body fat based on height and weight.

After prostate cancer diagnosis

How does nutrition affect men who have already been diagnosed with prostate cancer?

Are there certain foods or supplements they can take to help prevent progression of their cancer?  Or can they prevent a recurrence once they’ve had conventional treatment?  Our current articles include:

As you read these articles, remember that vitamins, supplements, and even some "natural" foods may have an effect on a man's body or may interact with other medications.

Many "natural" products that you purchase in stores are not regulated by the FDA.

That's why it's always prudent to check with a qualified medical professional before adding anything new to your loved one's dietary regimen.

Clinical studies about nutrition

While they are not perfect, clinical studies often (but not always) evaluate a larger number of men.

This helps us to know if the results are really significant or not.

In randomized clinical trials, the methodology (how the study is conducted) tends to be more stringent than industry studies.
