I added flaxseed oil to my regimen a few days ago when I realized that since I am not eating fish lately, and not eating other foods high in omega 3 fats, I am probably very deficient in omega 3. Here is a link to a nice website that shows you the nutritional composition of foods, and can show you which foods are highest in a certain nutrient for a 200 calorie serving. Very useful!
