The CaPSURE study found that men who reported eating the most eggs (approximately six per week) were twice as likely to have their prostate cancers progress than men who ate the fewest (less than half an egg per week). This unexpected finding led the authors to turn to choline, a nutrient in egg yolks that is highly concentrated in prostate cancer cells.
The Health Professionals Follow-up Study looked at about 27600 men who had no prostate cancer when they entered the study. in 1994. Those who reported eating at least 2.5 eggs a week had an 81 percent higher risk of dying of prostate cancer, compared to those who ate less than half an egg each week.
My Take: It is not yet clear if it is the eggs, or more specifically choline that matter. Could it be something else that egg consumers do to increase risk? Still, everything in moderation, and I would suggest consuming only a moderate amount of eggs. I’m Dr. Michael Hunter.
