Task 2: READING COMPREHENSION
Read the passage and choose the best answer for each question below.
Most human diets contain between 10 and 15 percent of their total calories as protein. The rest
of the dietary energy conies from carbohydrates, fats, and in some people, alcohol.The proportion of
calories from fats varies from 10 percent in poor communities to 40 percent or more in rich
communities.
In addition to providing energy, fats have several other functions in the body. The fat-soluble
vitamins, A, D, E, and K, are dissolved in fats, as their name implies. Good sources of these
vitamins have high oil or fat content, and the vitamins are stored in the body’s fatty tissues. In the
diet, fats cause food to remain longer in the stomach, thus increasing the feeling of fullness for some
time after a meal is eaten. Fats add variety, taste, and texture to foods, which accounts for the
popularity of fried foods. Fatty deposits in the body have an insulating and protective value. The
curves of the human female body are due mostly to strategically located fat deposits.
Whether a certain amount of fat in the diet is essential to human health is not definitely
known. When rats are fed a fat-free diet, their growth eventually ceases, their skin becomes
inflamed and scaly, and their reproductive systems are damaged.Two fatty acids,linoleic and
arachidonic acids, prevent these abnormalities and hence are called eseential fatty acids.They also
are required by a number of other animals, but their roles in human beings are debatable. Most
nutritionists consider linoleic fatty acid an essential nutrient for humans.
