Reading Comprehension Home Exercise – 08, PASSAGE B



Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose   to complex sugars such as amylase and amyl pectin. Nutritionists estimate that carbohydrates should make up about one- fourth to one- fifth of a person’s diet. This translates to about 75-100 grams of carbohydrates per day.

A diet that is deficient in carbohydrates can have an adverse effect on a person’s health, when the body lacks a sufficient amount of carbohydrates it must then upset protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketoses in the body that causes fatigue, lethargy, and bad breath.
