With 2,664 mg in every tablespoon, it is two and a half times more than the required dose of up to 1,000 mg of DHA. It is so named because it is derived from the liver of codfish. This fish oil also contributes in balancing cholesterol levels and blood pressure.

One-fourth cup of these nuts contains the same amount of DHA as cod liver oil, at 2,664 mg. Walnuts help enhance metabolism, bone health as well as controls diabetes. For those who want to lose weight, walnuts are a great help in managing weight. ALA or alpha-linoleic acid is also found in walnuts.
