can blood donation lower cholesterol levels

Changes in your diet and lifestyle prove the most effective method of lowering cholesterol. But some evidence exists that donating blood could also reduce your numbers. Science does not support donating blood as a primary means of reducing cholesterol, but healthy adults help others by giving blood.

The “iron hypothesis,” proposed by a cardiology professor at the University of Kansas, postulated that iron lost by women during menstruation helped protect them against cholesterol buildup. David G. Meyers wanted to find out if men who donated blood could obtain similar benefits. He found that men who donated blood frequently reduced their risk of heart disease by 30 percent compared to infrequent donors, according to a report published in “Transfusion” in June 2002. Meyers’ study examined the health of 3,000 men and post-menopausal women.
