The Gruppo Italiano per lo Studio della Soprawivenza nell'Infarto Miocardico (GISSI) Prevenzione Trial assessed 11,324 Italians after a heart attack and randomly assigned them to take polyunsaturated fatty acids, vitamin E, both, or neither.15 The polyunsaturated fatty acids led to a reduction in heart attacks and related events, but vitamin E had no effect. The ATBC study showed an increase in strokes with vitamin E.

These are not as bad for you as saturated fats, and they contain healthy essential fatty acids (discussed later), but they aren't healthy in large quantities. polyunsaturated fatty acids contain more than one double bond along the fatty acid chain. Replacing saturated fatty acids in the diet with polyunsaturated fatty acids (PUFAs) from vegetable oils will lower both total cholesterol and LDL levels and decrease blood pressure.52 However, it may also lower HDL. The third general type of fat is monounsatu-rated fat. These fats contain one double bond.

One study comparing 575 diabetics with 319 normals showed there was a problem incorporating polyunsaturated fatty acids into the cell membrane.55 All the diabetic red blood cell membranes were lower in polyunsaturated fatty acids. Plasma phospholipids, triglycerides, and cholesterol esters were also impaired, suggesting there is an impairment of polyunsaturated fatty acid metabolism in diabetes. This suggests that in non-insulin-dependent diabetes impaired insulin activity may be both a cause and an effect of membrane polyunsaturated fatty acid composition.

AMD was more strongly related to high intake of saturated fats in some studies [193-195, 197, 198] and to high intake of polyunsaturated fatty acids or monounsaturated fatty acids in other studies [185, 197, 198]. The intake of trans-fatty acids, provided in diets by margarines and other processed foods, was related to higher risk for AMD in two studies [185, 197]. Because fat intake often changes, particularly in relation to the common diagnosis for cardiovascular diseases, which can be related to AMD, these relationships are difficult to interpret.

The polyunsaturated fatty acids led to a reduction in heart attacks and related events, but vitamin E had no effect. The ATBC study showed an increase in strokes with vitamin E. Three other studies, involving observations of tens of thousands of people, the Cambridge Heart Association Antioxidant Study (CHAOS),16 the Heart Outcomes Prevention Evaluation (HOPE) study,17 and the Women's Health Study,18 also failed to find a protective effect for vitamin E on heart disease.

The major benefit of these polyunsaturated fatty acids called omega-3s, in particular DHA (docosahex-anenoic acid) and EPA (eicosapentaenoic acid), is that they make blood platelets less "sticky" thus protecting circulatory health, they may promote cognitive functioning, and there's also a growing body of evidence that they may reduce the inflammatory process in the entire body. It's this latter benefit—reducing inflammation—that seems to most benefit those trying to lose weight.

The oil from the seeds is a popular cooking oil; it is mild in flavor and rich in polyunsaturated fatty acids. The flowers can be used as a food coloring and are sometimes used as a cheaper substitute or adulterant for saffron. The Hopi Indians, for example, use it to color bread. Other Uses Safflower can be used as a dye; it has been used to redden cosmetics such as rouge and to make a yellow and red dye for fabric. Egyptians often colored linens used to wrap mummies with safflower. The dried flowers are sometimes included in potpourri.

When nutrition researchers talk about polyunsaturated fatty acids, they are often referring primarily to linoleic acid—a fatty acid found in nuts and seeds and most vegetable oils. In animal research, the consumption of polyunsaturated fatty acids increases the risk of some cancers.61 However, in humans, most,62'63,64 though not all,65 reports do not find an association between polyunsaturates and cancer risks. Sugar A preliminary study has reported an association between an increasing intake of sugar or sugar-containing foods and an increased risk of gallbladder cancer.

In another study, extracts of n-3 polyunsaturated fatty acids also led to a significant reduction in heart attacks in men with heart disease.51 Contrary to public opinion and to what you read in the papers, however, omega-3 fatty acids will not prevent heart disease. A recent analysis of 41 studies of omega-3 fatty acids with a total of 36,913 participants52 showed no reduction in cardiovascular events or total mortality with omega-3 supplementation using fish oils and other supplements. There was a 7% increase in cancer, which was not statistically significant.

In many of the aquatic animals in which it is found, astaxanthin has a number of essential biological functions, including protection against oxidation of essential polyunsaturated fatty acids, protection against UV light effects, pro-vitamin A activity, immune response, pigmentation, communication, and improved reproduction. In species such as salmon and shrimp, astaxanthin is considered essential to normal growth and survival and has been attributed vitaminlike properties.

The purpose of this review is to provide some additional "Pollyannas" in the form of polyphenols contained in berries, Concord grape juice, curcumin, and other natural products such as tea catechins, and the polyunsaturated fatty acids contained in such commodities as fish oils and nuts that may act as harbingers of good news for healthy aging. Note, however, that since there have already been multiple reviews of vitamins E and C (e.g., [1, 2]) and such supplements as ginkgo biloba (e.g., [3]), these topics will not be covered here.

Vitamin E also protects polyunsaturated fatty acids and vitamin A from free radical damage. Vitamin E neutralizes free radicals by donating a hydrogen atom from the hydroxyl group (HO) on the hexagonal head of vitamin E, as seen in Figure 5-4. Donation of hydrogen to a free radical is easiest for the alpha-tocopherol and gamma-tocopherol forms and slightly harder for the beta-tocopherol and delta-tocopherol forms. In cell membranes, the hexagonal head of vitamin E stays near the surface of the membrane. The tail of vitamin E is deeply implanted into the cell membrane.

Monounsaturated fatty acids have only one double bond, while polyunsaturated fatty acids have two or more double bonds. Monounsaturated fatty acids are further distinguished by the position of the double bond - omega-3 (on the third carbon), omega-6 on the sixth carbon, and so on. Oleic acid, the main fatty acid in olive oil, is a monounsaturated fatty acid as it has a single double bond. Common polyunsaturated fatty acids found in plant foods are linoleic and linolenic acids. Because of the double bonds, plant fats usually occur as oils, while animal fats tend to be solid.

Replacing saturated fatty acids in the diet with polyunsaturated fatty acids (PUFAs) from vegetable oils will lower both total cholesterol and LDL levels and decrease blood pressure.52 However, it may also lower HDL. The third general type of fat is monounsatu-rated fat. These fats contain one double bond. Monounsaturated fatty acids, as found in olive oil, show either no effect on HDL or an increase in HDL, thereby promoting a better effect than either PUFAs or saturated fats. Of all the types of fat, monounsaturated is the healthiest for your heart.

Although oatmeal's fiber content (7 percent) is less than that of oat bran (15 to 26 percent), it has been determined that the polyunsaturated fatty acids contribute as much to the cholesterol-lowering effects of oats as does the fiber content. Although oat bran has a higher fiber content, oatmeal is higher in polyunsaturated fatty acids. This makes oat bran and oatmeal quite similar in effectiveness.

They ate basically a plant-source diet (a chimpanzee diet) and their fat intake was less than 30 percent. The polyunsaturated fatty acids also require a certain balance. The significance we have hypothesized about the kinds of fats, between cis being transferred to trans, appears in some research49'50,51 that shows there are abnormal membrane phospholipid profiles in cooked fat, which is of major significance in both Type-1 and Type-2 diabetes. Insulin stimulates and glucagon inhibits a particular enzyme, which influences the availability of polyunsaturated fats for membrane incorporation.

Research does show that when you increase the ratio of polyunsaturated fatty acids to saturated fatty acids, there is an improved insulin binding.60 Rats fed high-fat diets became insulin resistant. Saturated fatty acids caused the most deterioration. Linolenic acid (LA) caused the least problem. The use of omega-3 from flaxseed oil normalized insulin function in the saturated fatty acid group. Research has also shown that the higher the amount of saturated fatty acids in the cell membrane, the more insulin resistance there is.

All the diabetic red blood cell membranes were lower in polyunsaturated fatty acids. Plasma phospholipids, triglycerides, and cholesterol esters were also impaired, suggesting there is an impairment of polyunsaturated fatty acid metabolism in diabetes. This suggests that in non-insulin-dependent diabetes impaired insulin activity may be both a cause and an effect of membrane polyunsaturated fatty acid composition. It is complicated, but the point is to show that Type-2 diabetes is associated with dysfunctional fat metabolism.
