Americans generally want to avoid fat (fat phobic). Dr. Dyerberg says you should preferably replace other fats with fatty fish. With regard to supplementation, if you do not like fatty fish, supplements are ok, but you have to cut down on another fat, and you are talking about 1 or 2 grams, which would be just 2 less cookies. And the supplements help the body work better. One gram of supplement is probably sufficient.
