The Function of Fats in Our Life
Fats along with proteins and carbohydrates, are one of the three nutrients used as energy sources by the body. The energy produced by fats is 9 calories per gram. Proteins and carbohydrates each provide 4 calories per gram. Total fat; the sum of saturated, monounsaturated and polyunsaturated fats. Intake of monounsaturated and polyunsaturated fats can help reduce blood cholesterol when substituted for saturated fats in the diet. A slang term for FAT or obese. In chemistry, a compound formed from chemicals called fatty acids. These fats are greasy, solid materials found in animal tissues and Fats are the major component of the material of a flabby body, commonly known as blubber.

We need some fat-it makes up part of our brains, it protects some of our joints and it provides reserves for when we're sick-but it slips down so effortlessly, it's easy to overindulge.
Fat provides needed energy. It is difficult to eat the large amounts of Food in a very low fat diet to get all the energy you need. Fat is needed so yourbody can absorb the fat soluble vitamins A, d, E, K, and prevent deficiencies of these vitamins. Provides back-up energy if blood sugar Supplies run out (after 4-6 hours without Food). Provides insulation under the skin from the cold and the heat. Protects organs and bones from shock and provides support for organs. Fat insulates nerve fibers and gemstone to help transmit nerve impulses. Fat is part of every cell membrane in the body. It helps transport nutrients across cell membranes and pyrimidines. Your body uses fat to make a variety of other building blocks needed for everything from hormones to immune function. What happens if we don't have enough fat?
Dry, scaly skin
HAir loss
Low body weight
Cold intolerance
Bruising
Poorgrowth
Lower resistance to infection
Poor wound healing
Loss of Menstruation
Food Sources of Fat
High intakes of fat contribute to becoming overweight; being overweight increases the chance of developing a number of diseases such as diabetes, heart disease and high blood pressure.
Not only do we need to restrict the amount of fat, but we also need to consider what type of fat is restricted, as different types of fat have different effects on blood cholesterol levels and heart health.
Food contains a mixture of three types of fat; polyunsaturated, monounsaturated and saturated fats. One type of fat usually dominates in food for example, butter is mainly saturated fat and olive oil is mainly monounsaturated. All fatscontain approximately the same amount of kilojoules or energy and if eaten in large amounts will lead weight gain.
Polyunsaturated Fats -lowers blood cholesterol and heart health-encourages Good food sources are; Vegetable oils such as safflower, soy bean, sunflower, corn, Wheat germ, cereals and breads, wholegrain wholemeal wholesome Polyunsaturated margarines, Fish oils, naturally present in Fish, Seeds and most nuts.
Omega-3 fats are a type of polyunsaturated fat, found mainly in oily fish (e.g. salmon, mackerel, sardines, herrings), canola oil, flaxseed oil (linseed oil) and walnut oil. These fats help to reduce blood clotting, blood pressure and blood fat levels.
Monounsaturated Fats do not raise blood-cholesterol andencourages heart health-Good food source are; Avocados, peanuts, peanut oil and peanut butter, Olive oil, olives and olive oil-based Canola oil and margarines, monounsaturated table spread, Almond and hazelnuts.
Saturated Fats raise blood cholesterol-and promote heart disease – These are the ones to reduce or avoid Major food sources are; DAiry fats such as butter, clarified butter, cultured butter, butter/margarine, mix or full cream Milk homogenised, Hard cheeses, cream cheese, sour cream, ice cream and cream, Meat fats such as lard, dripping, suet, beef tallow chefade, White and visible fat on beef, mutton, lamb, Pork, poultry, Processed meat, e.g. luncheon, salami, sausages, tinned copper drail wire most corned beef, mince pies and pates fattyTropical oils such as coconut,coconut cream, palm oil and kremelta.
Trans Fats are the other type of fat that can raise your cholesterol level just like saturated fats-Trans fats can be formed when vegetable fats are processed in certain ways. Some polyunsaturated fats are trans fats when converted to vegetable oils are chemically harden to make it spreadable such as margarines. This process is called hydrogenation. These fats may be found listed in the food ingredients on packaged foods as vegetable fat, margarine and vegetable shortening baking. Foods containing this fat includes pastries, biscuits, crackers, Granola bars, commercial cakes and muffins.
Daily Usage of Fats
We all need some fat in our diets. In fact, it's virtuallyimpossible to have a fat-free diet as most foods, even fruit and veg, provide small amounts of fat. As well As providing the body with a concentrated source of energy, certain components of fat are essential parts of our body cells and are needed to make hormones. Fat also helps to insulate our body and small amounts around the major organs have a protective effect. Several vitamins (vitamins A, D, E and K) are also fat-soluble and tend to be found in foods with a high fat content. Very low fat intakes mean that intakes of these vitamins, in turn, are often extremely low, too.
The DepartMent of Health recommends that no more than a third of calories come from this nutrient, while most weight loss plans rarely recommend less than 20% of calories come fromfat.
Nutritional Safety
Some people do not do well if their diet is too high in fat, regardless of what type. They will develop a slow metabolism, constipation, lethargy, and skewed cholesterol levels if they eat too much fat. These people do best with a diet rich in fruits, vegetables, and whole grain foods.
Very few fats are bad in and of themselves. Trans fat is an oil that has been chemically manipulated to be more solid. It has been found to be particularly harmful to the arteries and is not recommended at any level in the diet. The lower the better on this one!
Usually it is the proportion of fat that is the problem. Recently it has been found that a diet with too much omega-6 fat and not enough omega-3 fat leads to inflammation andsuppression of the immune system. So balancing these fats is very important.
Too much fat in your diet puts you at risk for Obesity, Coronary Artery Disease, High Cholesterol, Myocardial Infarction and Hypertension.
