@julianned The omega 3s have to do with the food chain. If you eat grass fed meat, they are higher in Omega 3 because it is in the grass. Corn fed meats have a lot more of the Omega 9s than Omega 3 which is from the corn. 9s are highest in corn and those are inflammatory. Fish oil is high in Omega 3 because of the algae in the ocean plankton that the fish eat. You can also use flax oil, it has a lot of Omega 3. It needs to be kept away from oxygen because it spoils. You can grind flax seed and use it right away, keep it in the fridge, or take it in a capsule. If you add a lot of vegetables to your diet, you'll add omega 3. Some of the brands for fish oil test for mercury levels and harvest fish from cleaner areas of the ocean, like Carlson's. I'm so glad you asked the question about your vision. Isn't it exciting to know that the choices you make now can change your future for the better? I knew about the supplements because my father in law had macular degeneration, but I didn't know why it worked and how it helped until I found the study. I don't eat much seafood because of the mercury. I have cut most sugars out of my diet and I use stevia to sweeten my coffee. Eating healthy like that will also reduce your risk for heart disease and cancer as well as eye sight issues.
