Abstract

Carbohydrates are the most abundant class of organic compounds found in living organism. They are originate as products of photosynthesis, an endothermic reductive condensation of carbon dioxide requiring light energy and the pigment chlorophyll. Carbohydrates are called saccharides or, if they are relatively small, sugars. There are basically three types of carbohydrates. Sugar or Simple Carbohydrates: Natural sugars are found in fruit and vegetables. Refined sugars are found in biscuits, cakes and pastries. Starch or complex carbohydrates. Complex carbohydrates, also referred to as starch, are made up of many sugar units. Fiber: Fiber comes from plant foods so there is no fiber in animal products such as milk and other dairy products, eggs, meat, poultry and fish. Physiological Effects Carbohydrates have a wide range of physiological effects which may be important to health Glycemic Index The glycemic index or GI describes this difference by ranking carbohydrates according to their effect on our blood glucose levels.
