Facts About FatsFats are important for the human body. Since March 1990 the US health authorities suggested that all Americans over the age of two should reduce their daily intake of saturated fats below the 10% of total calories and their total intake of fat below 30% of daily calories. These suggestions were first introduced in the 1960’s and were at that time a fair representation of the evidence that saturated fats and excessive total fats in the diet can be the cause of cardiovascular disease and certain cancers. Nutrition science made mighty advances since the recommendations made their laborious way through the heavy committies of the US health authorities. The advice of the 1960’s is now obsolete. Fat is your body’s major fuel and some people still think that you have to eat much of it in order to keep your energy level high. They got it wrong. A slim man of 85 kg who has only 10% body fat carries 7% In contrast to his fat store, his other major source of fuel,his 450 grams of glycogen, holds only 1800 calories, at 4 calories per gram. The limit on energy is always glycogen, because your muscles So even a very slim person never runs out of fat. You need to eat very little in order to maintain a sufficient fat store. This means between 10% and 15% of daily calories should be sufficient. Bodyfat is put on much easier by eating fat than by eating other food. The current government advice that it’s ok to eat 30% of daily calories in fat encourage you to eat a lot of it. The result is waddling Overwhelming evidence shows that even moderate overweight is a direct cause of many diseases and the risk of disability and death is on the increase in almost all diseases.

Besides the fat our body use for fuel, it requires many special fats They function as part of the cell membranes around every cell and as parts of your brain, inner ear, eyes, adrenal glands and sex organs. Our body can make these special fats only if it gets the right raw materials from our diet, which are two essential fats our body can’t make: linoleic acid and alpha-linolic acid. Both of which are Unfortunately, essential fats are scarce in the average diet. The best source of inoleic and alpha-linolenic acids is flax or linseed oil. Other sources are: pumpkin seeds, walnuts, soybeans and canola oil. Dark green leaves of leaf vegetables also contain small amounts. OMEGA-3s FIGHT CANCER. This evidence is vital to your health because studies show that omega-6 fats, although they are essential for some functions, also produce inflammatory prostaglandins that promote cancer growth. Omega-3 fats keep this cancer effect of omega-6 fats under control. Unfortunately, the American diet is very low in alpha-linolenic acid (omega-3), but high in linoleic acid (omega-6). Most vegetable oils have little or no omega-3 fats and a lot of omega-6 fats. The only common oil that contains a healthy balance is organic flaxseed. The benefits of omega-3 fats don’t stop with cancer. The evidence is impressive that a high intake of omega-3 fats (about a tablespoon of organic flaxseed oil per day) goes a long way to inhibit cardiovascular disease Article Tags: Health Authorities, Daily Calories, Omega-3 Fats Source: Free Articles from ArticlesFactory.com
