Healthy cooking at easy-home-cooking
By Dr. Chef
Dietary fats are chiefly true fats or simple lipids. These include the animal and vegetable fats and oils which consist chemically speaking, of fatty acids and glycerol. These are rendered more accessible to digestive and absorptive processes by the bile from the gallbladder. Generally speaking, vegetable sources contain more unsaturated fatty acids. Some vegetable oils reduce the cholesterol content of the blood when consumed in high polyunsaturated fatty diets and are, therefore, recommended for people with heart or liver disorders or as a preventive measure. Fats are potent carriers of energy in the body, and thus constitute valuable reserves for the body. Fats have the highest calories value of the nutrients supplying energy. Fats are also important in the process of body maintenance and regulation. Extra fat in the diet is partially stored away in fat deposits. During periods of under nutrition, the body lives mainly on these deposits of fat. Fat comes from animal and vegetable food: milk and milk products, animal fats in such foods as meat, poultry, fish, and egg yolk; and vegetable fats including margarine, seed and vegetable oils, fruits or vegetables (avocados, olives); and nuts. Any prepared foods such as salad dressings, cakes, pastries, gravies, and sauces contain fat. No precise levels for either the quantity or type of fat in the normal diet have been established.
Calories : The previously mentioned energy sources – protein, carbohydrates, and fat – create warmth during the process of metabolism. This warmth is measured in calories, 1 calorie representing the amount of warmth necessary to increase the temperature of 1 kg of water by 1oC. The more physical work a man does, the more nutrients are burned. Different foods produce varying amounts of energy and for this reason it is important to know their calorific values. Foods can be evaluated on the basis that 1 gm protein creates 4.1 calories, 1 gm carbohydrates creates 4.1 calories and 1 gm fat created 9.3 calories of warmth. Since there are slight variations in calorie values obtained for different foods within a given group, the figures are rounded off to:
1 gm protein yields 4 calories
1 gm carbohydrates yield 4 calories
1 gm fat yields 9 calories
