Ask the Expert: Omega-3 Fatty Acids - Dr. Frank Sacks, Professor of Cardiovascular Disease Prevention, Department of Nutrition, Harvard School of Public Health
"We need omega-3 fatty acids for numerous normal body functions, such as controlling blood clotting and building cell membranes in the brain, and since our bodies cannot make omega-3 fats, we must get them through food. Omega-3 fatty acids are also associated with many health benefits, including protection against heart disease and possibly stroke. New studies are identifying potential benefits for a wide range of conditions including cancer, inflammatory bowel disease, and other autoimmune diseases such as lupus and rheumatoid arthritis."
