Dietary fats also known as lipids are one of the three classes of primary nutrients. The other two are proteins and carbohydrates which we are not going to discuss at this time. The major function of fat is to provide quick energy for the body. Pound per pound, fat contains more energy (in the form of calories) than protein and carbohydrates. There are three types of fat found in the body; triglycerides, cholesterol, and phospholipids.
A quick description of Omega-3, fatty acids consist of chains of carbon atoms linked together by chemical bonds. On one end of a carbon chain is a methyl group (a cluster of carbon and hydrogen atoms). On the other end is a carboxyl group (a cluster of carbon, oxygen and hydrogen atoms). The chemical bonds between carbon atoms can be either single or double bonds (single bond is weaker than a double bond).
Single bonds have more hydrogen molecules around them than double bonds. These chemical bonds determine whether a fatty acid is saturated or unsaturated (the more hydrogen the more saturated a fatty acid is). Fatty acids also come in different lengths: short chain fatty acids have fewer than 6 carbons, while long chain fatty acids have 12 or more carbons. Each have a different function in the body.
Omega-3 fatty acids a well known fatty acid and is a type of polyunsaturated fat (less hydrogenated) which must come from the diet. The best known sources are fish, shellfish, fish oils and organ meats. The nutrients naturally occurring in leafy greens, nuts and flaxseed also provide the fatty acids we need.
Omega-3 is an essential nutrient for health. We need omega-3 fatty acids for numerous normal body functions, such as controlling blood clotting and building cell membranes in the brain, and since our bodies cannot make omega-3 fats, we must get them through food. Omega-3 fatty acids are also associated with many health benefits, including protection against heart disease and possibly stroke. In addition to these established benefits for cardiovascular disease, omega-3 fatty acids in high doses (6 grams per day) are used to treat depression. New studies are identifying potential benefits for a wide range of conditions including cancer, inflammatory bowel disease, and other autoimmune diseases such as lupus and rheumatoid arthritis.
Omega-3 is good for high blood pressure, high lipid (fat) levels in the blood (hyperlipidemia), certain skin/scalp conditions (such as atopic dermatitis, psoriasis), ulcerative colitis, or certain blood circulation problems (such as Raynaud’s syndrome).
Omega-3 fatty acids are available in capsule, tablet, and liquid forms at your local or internet health food store. When purchasing omega-3 fatty acids, look for name brands like Kal, Source Naturals, Natures Plus, and Twinlab to ensure quality and purity of the product you purchase.
