FUNCTION OF CARBOHYDRATES

Carbohydrates provide the body with a source of fuel and energy that is required to carry out daily activities and exercise. Any extra energy is stored in the body until it is needed.

Our bodies need a constant supply of energy to function properly and a lack of carbohydrates in the diet can cause tiredness or fatigue, poor mental function and lack of endurance and stamina.

Carbohydrates are also important for the correct working of our brain, heart and nervous, digestive and immune systems.

Fibre, which is also a form of carbohydrate, is essential for the elimination of waste materials and toxins from the body and helps to keep the intestines disease-free and clean.                                                        
     
 Carbohydrates are an essential part of a healthy diet and should make up 50% of our daily calorie intake. The majority should come from complex carbohydrates, preferably the wholemeal varieties, as well as a large intake of fruit and vegetables.

Simple carbohydrates of the refined kind, including refined sugar (sucrose) should be limited. They have no nutritional value and are generally high in sugars and fats.

To make it really simple:

"Good" carbohydrates are:

Bran, wheat germ, wholemeal bread, brown rice, potatoes, all forms of pasta but especially wholemeal pasta, barley, oats, lentils, chickpeas, beans, peas, corn, sweet potatoes, wholegrain cereals such as Weetabix, muesli, All bran, brown breads, root vegetables such as carrots, turnips, leeks and radishes.

"Bad" carbohydrates are:

Sweets, sugary breakfast cereals, cakes, pastries, syrup, table sugar (sucrose), fizzy drinks, biscuits, chocolate. 

WHAT IS CARBOHYDRATES??

A carbohydrate is an organic compound that consists only of carbon, hydrogen, and oxygen, usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cn(H2O)n (where m could be different from n). Carbohydrates are technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones.
