Essential Fatty Acids
What are Essential Fatty Acids?
Essential fatty acids (EFAs) are fatty acids (from polyunsaturated fats) necessary for body functions and processes but not made in sufficient quantities by the body to meet those needs. Therefore, EFAs must be consumed in food or supplement form.
Two important EFAs are linoleic acid (an omega-6 fatty acid) and linolenic acid (an omega-3 fatty acid). EPA (eicosapentaenoic acid) and DHA (docosahexanoic acid) are omega-3 fatty acids found in the tissues of coldwater fish.
The body needs EFAs to help synthesize certain hormones and hormone-like substances, provide structure for cell membranes, keep the brain and nerves healthy, and support natural growth.
Health Benefits
A lack of EFAs in the diet can lead to deficiency side effects such as reproductive shut-down, poor skin health, and liver or kidney disorders. Additionally, malnutrition may develop as EFAs are necessary for the proper break down of the fat-soluble vitamins A, D, E and K. Omega-3 fatty acids in particular are absolutely vital for proper brain, eye and heart health.
Aside from maintaining good health, omega-3 fatty acids in particular offer other health benefits. Omega-3’s have been found to have an anti-inflammatory effect, and may help those suffering from inflammatory diseases, rheumatoid arthritis, lupus and other autoimmune disorders. Additionally, these fatty acids may help ward off mental disorders such as depression by supporting the brain, which is largely composed of fatty tissue. Studies are underway to investigate possible cancer fighting properties of omega-3 fatty acids.
Usage Indications
Typical American diets are usually lacking in omega-3 fatty acids and over abundant in omega-6 fatty acids (often found in packaged and processed foods). The optimal ratio of these nutrients is 1 to 5, respectively.
Good sources of omega-6’s: vegetable oils such as corn, sesame, soybean and sunflower, seeds, nuts, grains and leafy green vegetables.
Good sources of omega-3’s: oils such as flaxseed, soybean, walnut, or canola, and liquid or soft margarine made from these oils, and coldwater fish (mackerel, salmon, tuna, etc.).
