I've been reading a lot about DHA and omega threes in the last week because DHA is good for your eyes and my little girl has eye trouble. Here is what I've learned the best places to get DHA is cod liver oil, wild alaskan salmon, and the seaweed that the salmon and cod eat. The other two omega threes I've heard about are ARA and ALA. Our bodies can convert ALA to DHA but its a slow inefficient process maybe? I'm not sure haven't read a lot about that. I'm one that feels strongly that you should when possible eat the nutrient in the whole food. I'm thinking my plan is to eat wild alaskan salmon 1-2 times a week and I'm still looking into giving my baby cod-liver oil. (I'm not sure about her getting too much vit D, or not getting a good brand of cod liver oil). Another source for DHA is egg yolks and you can get eggs from free range chickens that have been fed a fish meal diet and they have much much higher levels of DHA in them. If you learn more about getting DHA through seaweed please share your info here!
