Several studies indicate a potential link between choline and the reduction of breast cancer risk. A recent study from the University of North Carolina which looked at more than 3, 000 adult women, found that those with the highest intakes of choline (around 450 mg/day which is considered an adequate intake) had a 24% lower risk for developing breast cancer. Most of the choline in the diet is coming from eggs and milk in this study. An egg contains about 125 mg of choline or around 25% of your daily needs. Choline's role is normal functioning of cells whatever your age.
