Over the next several blogs, we’ll look at some dietary elements that might affect your risk of getting prostate cancer. Up today? Coffee. We now have some data suggesting that there might be an association between coffee consumption and lower risk. Examples include:
- Among 48,000 professionals, those who drank more than 6 cups of coffee daily had a 60 percent lower risk of lethal prostate cancers (as compared to those who drank no coffee). Coffee, not caffeine, seemed to matter. This study asked about code use every 4 years over a 28-year period.
- The National Institutes of Health (NIH)-American Association of Retired Persons (NIH-AARP) study found no link, but it asked participants about coffee only once over an 11 year period.
The bottom line: While we lack high level evidence linking coffee consumption to a decrease in the risk of the lethal form of prostate cancer, the Health Professionals Study is suggestive of an association. The NIH-AARP study, albeit suboptimal, did not find such a link. I typically recommend that patients who enjoy coffee do so in moderation, limiting their daily intake to no more than 3 to 4 cups daily.
Certainly, those who wish to lower their personal risk of lethal prostate cancer might:
- Lose (or don’t gain) excess weight
- Quit (or don’t start) smoking
- Avoid calcium supplements, unless your diet is deficient in calcium
- Eat a heart healthy diet, with lots of fruits and vegetables, low-fat (not high-fat) dairy, whole grains (instead of refined grains), fish and poultry (instead of red meat), egg whites (instead of whole eggs), and oils (in lieu of shortening or butter).
