Trang 1 BÀI TẬP – VẬN DỤNG VỚI LỜI GIẢI CHI TIẾT READING COMPREHENSION 1: Read the following passage and mark the letter A, B, C to indicate the correct answer to each of the questions. While fats have lately acquired a bad image, one should not forget how essential they are. Fats provide the body's best means of storing energy, far more effiient energy sources than either carbohydrates or protein. They act as insulation against cold as cushioning for the internal organs, and as lubricants. Without fats, energy would be no way to utilize fat soluble vitamins. Furthermore, some fats contain fatty acids that contain necessary growth factors and help with the digestion of other foods. An important consideration of fat intake is the ratio of saturated fats to unsaturated fats. Saturated fats, which are derived from dairy products, animal fats, and tropical oils, increase the amount of cholesterol in the blood. Cholesterol may lead to coronary heart disease by building up in the arteries of the heart. However, unsaturated fats, derived from vegetable oils, tend to lower serum cholesterol if taken in proportion twice that of saturated fats. The consumption of a variety of fats is necessary, but the intake of too much fat may lead to a variety of health problems. Excessive intake of fats, like all nutritional excesses, is to be avoided.
