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.

What is BMI?
BMI stands for Body Mass Index. It is worked out from your height and weight, and doesn’t take into account age or sex. From your BMI you can work out if you are Underweight, Normal Weight, Overweight or Obese. BMI is a good general guide, however it should not be taken as law. It works on height and weight, and assumes that weight correlates to body fat. On a person that has more muscle than fat (for example, a body builder) then the BMI would not be accurate.
