CARBOHYDRATES AND OUR DIET

The immediate source of energy for our cells that circulates in the blood is the simple sugar glucose. This fuel can be quickly produced from dietary carbohydrates and proteins or by the breakdown of glycogen stores. The principal energy storage in the body is in the form of fat, which is a long-term reserve made available to cells at a much slower rate.
Carbohydrates are vital to the primary energy cycle in the biological world. In a process called photosynthesis, plants combine carbon from the carbon dioxide in the air, water from the air and ground, and energy form the sun to produce stored carbohydrate energy as well as the waste product oxygen.
Carbohydrates have a powerful effect on the body. The proportion of your diet that is carbohydrate and, more important, the type of carbohydrate you consume, have vital effects on your health. Of the three sources of calories – carbohydrates, fats, and protein – carbohydrates are the only one not necessary for survival. Without certain essential fats and the right protein building blocks, you could not live. You don’t need carbohydrates to build the structure of your cells; you could get all the energy you need from fat and protein. The key to a well-balanced diet includes some carbohydrates, it does not revolve around carbohydrates.
