Alpha-linolenic acid (omega improves 3) and linoleic acid (omega 6) are the two essential fatty acids; they play a key role in the immune system, vision, and cell structure. Good food sources for these essential fatty acids include vegetables oils that can be found in mayonnaise or salad dressings. While uncommon in the US where fat is abundant, a deficiency in essential fatty acids can result in diarrhea, anemia and skin problems. Another omega 3 fatty acid, which is not one of the EFAs, is eicosapentaenoic acid. Eicosapentaenoic acid is abundant in fish such as salmon, halibut, and trout. Triglycerides are mainly responsible for energy storage and the insulation of the body and its organs. They also transport the fat-soluble vitamins and contribute to taste and feeling full after eating a meal (2). |

| On average, about 3 percent of total calorie intake in the United States can be attributed to trans-fats (3,4). skinfold caliper Studies have found that trans-fats raise LDL-cholesterol and total cholesterol, as do saturated fats; other skinfold caliper findings of studies suggest a correlation of cardiovascular disease and trans-fat intake (3,5). Since there is concern about the rising evidence of this correlation, the Food and Drug Administration (FDA) now requires information about trans-fat content of foods on nutrition food labels. These new labels are scheduled to go into effect on January 1, 2006. In order to avoid foods high in trans-fats there is a new food processing method called “low-trans hydrogenation” which is more expensive than regular hydrogenation but would yield a significantly lower percentage of trans-fatty acids in food products and therefore seems to represent a possible alternative to the conventional method (5). What functions do fats serve? Fat can be found in various forms in the diet and each form can serve a different purpose (2). |
