In particular, omega-3 fatty acids help to reduce cholesterol and increase circulation to the retina.  Omega-6 fatty acids are important as they protect cells from degenerative changes and reduce inflammation throughout the body.

A word of caution about your fish intake the effect of mercury which contaminates the larger ocean predator fish (tuna, swordfish, marlin, sharks, etc): too much mercury in the body can raise your blood pressure.


Small fish like sardines are a safe choice, but there are non-swimming sources of essential fatty acids out there too.  Find omega-3s in flax seed oil, black current oil, walnuts and walnut oils, dark leafy vegetables, eggs (preferably from free range chickens), spices (including mustard, fennel, cumin, and fenugreek).  Get your omega-6s from evening primrose, borage and black currant oils.
