Omega 3s This is a polyunsaturated fatty acid
found in high amounts in
flax seeds (picture at right),
English walnuts and in seafood, especially higher fat, cold-water
varieties like tuna, salmon, sardines and mackerel. They may
prevent blood platelets from sticking to artery walls, which
lowers the risk for blocked blood vessels and heart attacks.
How fish oils work isn't certain but the leading theory is:
When the heart muscle is stressed, the fish fat stabilizes the
heart cells which allows the heart to beat regularly. When there
is trouble, EPA (eicosapentaenoic acid) is released from the cell
membrane and it suppresses the extra beats. The omega 3 fatty
acids restores a balance disrupted by excessive consumption of
omega-6 fatty acids and saturated fats. Omega 3s can also help to
lower blood triglycerides.
