Low Fat – Not No Fat
Tuesday, December 30th, 2008Low fat foods such as potatoes, rice, pasta, vegetables, fruit, breads, cereals and beans are the basis of sound weight loss programmes for this reason. They are filling, nutritious foods that won’t add weight. However, take care if you add extra fats such as butter or margarine, sour cream, or cook by deep frying etc.
Years ago, people often avoided starchy foods, such as bread and potatoes, in the belief that they were fattening. But metabolic studies over the past 15 years have shown that carbohydrates are not readily converted to body fat, but are burnt off. On the other hand, fats are not oxidised but are efficiently stored as body fat. It is chemically easier for the body to turn food fat into body fat than to break down carbohydrate and re-form it as fat.
Fat also appears to give less satisfaction than carbohydrate. Because we need carbohydrate as a fuel for the brain, liver and muscles to function, eating enough carbohydrate at each meal to meet the needs of these vital organs helps to satisfy our hunger, yet not put on weight. So a low fat, high carbohydrate diet, the opposite of the western way of eating is now considered the secret of better weight control.
High intakes of saturated fat have been linked to illnesses, such as coronary heart disease, mature age diabetes and certain types of cancer, notably cancer of the bowel and the breast. Cutting back on saturated fat and substituting small quantities of unsaturated fats and oils is part of the dietary strategy to ward off these problems
A small amount of fat is essential for good health, vitality and a clear skin. Children, especially, need some fat in their meals to grow and develop correctly. A low fat diet is not recommended for your children under the age of 5 years.
Fat acts as a carrier for the fat soluble vitamins (vitamins A, D, E and K) and also supplies two essential fatty acids. Known as linoleic acid and alpha linolenic acid, these fatty acids cannot be made in the body and so must come from food.
A minimum of 1 or 2 tablespoons of good quality oil a day is generally sufficient to supply these vitamins and essential fatty acids. It can also come from other fat containing foods such as margarines, mayonnaise, salad dressing, nuts, seeds, avocados, wheat germ and whole grains. While these foods are high in fat, the type of fat they offer is usually the desirable monounsaturated or polyunsaturated types.
So, clearly, a low fat/healthy fat way of eating is the way to go.
