Carbohydrate is found in a lot of the food that we eat. It provides energy for our body, and can be broken down into three groups according to the number of saccharide (sugar) units they contain.
Carbohydrate is broken down by the body into simple sugars, which are absorbed into the bloodstream. As the amount of sugar in your bloodstream rises, the pancreas produces insulin which moves the sugar from your bloodstream and into cells where it is used for energy. Simple carbohydrates are broken down very quickly in the body, and are a provider of quick energy.
Complex carbohydrate contain up to thousands of glucose units. Some of the most common polysaccharides are starch, fibre and glycogen. Complex Carbohydrate is what you eat from grains, nuts, legumes, vegetables (starch) and other foods such as breads, cereals, pasta and fruits. These complex carbohydrates break down slower in the body, and are important to support exercise. Ideally, if you are exercising, you should make sure to eat both simple and complex carbohydrates in your everyday food.
