Studies have found that consumption of linoleic acids (an essential fatty acid) and vitamin C decrease drying and wrinkling of the skin. Linoleic acid plays a key role here because once ingested, linoleic acid turns into gamma linolenic acid also known as GLA. Through a series of steps, GLA is eventually converted to prostaglandin 1, which has an anti-inflammatory effect on the skin and is also effective in regulating water loss and protecting the skin from damage. You can also supplement with evening primrose oil or borage oil, both contain high amounts of GLA. Watch my video with the wonderful Kristen Ma to learn more about evening primrose oil here: http://www.youtube.com/watch?v=O-ClA89C-K0.
Walnuts contain both linoleic acid and omega 3 fatty acids. This is excellent because in our western diets we tend to have a higher amount of omega 6 fatty acids compared to omega 3 and this can cause an imbalance. Additionally, some of the major sources of omega 6 fatty acids in the western diet come from corn, wheat and soy bean oil. These have been heavily modified and now cause digestive and health problems for many individuals.
A handful of walnuts make a great snack, or can be added on top of a salad or are great additions when baking healthy treats.
