Paleo Foods: Walnuts

Compared to other nuts, walnuts contain a large amount of the omega-3 fat alpha-linoleic acid (ALA). However, it's important to remember that ALA (found in plants, nuts and seeds) can be converted to EPA and DHA (a form our body can use), but the process is inefficient. Seafood is a better choice to obtain Omega-3 fatty acids.

Walnuts are an excellent source of fat to keep us full and satiated. They're also a good source of vitamins and minerals including copper, manganese, magnesium and B vitamins.

A study showed walnuts increased blood levels of melatonin in rats. When fed walnuts, the blood level of melatonin increased to 3.5 nanograms of melatonin per gram. Typical melatonin supplements contain between 0.5 and 5 milligrams. Melatonin is a hormone that helps to regulate circadian rhythms.
