The list of benefits provided by omega-3 is lengthy. Some of these include lowering cholesterol, and the prevention of diabetes and depression. It has also been shown that the nutrient promotes child development during pregnancy. The bad news is that the human body cannot synthesize omega-3; therefore, it has to be present in the diet. You can incorporate dietary supplements to your diet that include omega-3 such as flax or chia oils and grains. They can be bought at natural health stores.
