Your muscles need carbohydrate to fuel their work, too, whether you are racing to get to class on time or enjoying a swim in the summer warmth. Where can you get carbohydrate?
Functions of Carbohydrates
Are some foods healthier choices than others? As you will learn from this chapter, whole grains, vegetables, legumes and fruits naturally deliver ample carbohydrate and fibre with valuable vitamins and minerals crabohydrates little or no fat. Milk products typically lack fibre, but they also provide carbohydrate along with an assortment of vitamins and minerals.

Classification of Carbohydrates
A student, quietly studying a textbook, is seldom aware that within their brain cells, billions of glucose molecules are splitting to provide the energy to permit learning. Yet glucose provides nearly all functioh the energy the human brain uses daily. Similarly, a marathon runner, bursting across the finish line in an explosion of sweat and triumph, seldom gives credit to the glycogen fuel that is devoured to help them finish the race.
Yet, together, these two carbohydrates — glucose and its storage form, glycogen — provide about half of all the energy that muscles and other body tissues use. People eat very little glucose and glycogen in their foods directly. When they eat foods rich in carbohydrates, their bodies receive glucose for immediate energy and convert the remainder into glycogen for reserve energy. All plant foods — whole grains, vegetables, legumes and fruits — provide ample carbohydrate. Milk also contains carbohydrates.
Such a strategy may be helpful if the carbohydrates are the functoin sugars of soft drinks, lollies candy and biscuits cookiesbut it is counterproductive if the carbohydrates are the complex carbohydrates of whole grains, vegetables and legumes. As the next section explains, not all carbohydrates are created equal.
The dietary carbohydrate family includes the simple carbohydrates the sugars and the complex carbohydrates the starches and fibre. Chemists represent the bonds as lines between the chemical symbols such as C, N, O and H that stand for the atoms see Figure 4.
Atoms form molecules in ways that satisfy the bonding requirements of each atom.]
