|Most fish oils like cod liver oil contain large amounts of omega 3 fats. Many studies have shown that regular consumption of omega 3 fats from flax, fish oils and fatty fish (such as salmon, mackerel, anchovies, sardines and herring) are associated with many heart and cardiovascular benefits. Such omega 3 benefits reported in various studies include significantly lower rates of first and repeat heart attacks,|
significantly lower levels of blood triglycerides, improving heart beating in congestive heart failure patients, and reducing rates of heart irregularities and other heart rhythm problems.
A good review of the heart benefits of omega 3 oils by Roth and Harris is found in the January 2010 Currents in Atherosclerosis Reports. For maximum health, try to eat at least 2 3 ounce serving of fatty fish weekly and/or consume at least one teaspoon daily of fish or flax oil.
