About the Glycemic Index

The Glycemic Index (GI) relates to the way your body?s sugar levels respond to certain foods. Foods are given a rating from 0 ?100 on the glycemic index with glucose in the highest position. High Glycemic Index foods (such as simple carbohydrates) will increase the body?s sugar levels rapidly whereas low glycemic index foods will increase the body?s sugar levels slowly. A good understanding of the glycemic index can assist in weight loss and help control diabetes.

How Does the Glycemic Index work?

The glycemic index is complicated and cannot be generalised to all people. Different people will have different reactions to food. The body?s response to food will relate to several factors including; age, activity level, insulin levels, time of day, amount of fibre and fat in the food, how refined (processed) the food is, and what was eaten with the food. In addition to this, other factors such as the ratio of carbohydrates to fat and protein as well as how the food was cooked (eg. Boiled compared to fried or baked) and metabolism will determine the way your body?s sugar level responds after eating. Foods that have a low glycemic index will have little effect on the body?s sugar levels. Comparatively, foods that have a high glycemic index will have an instant affect on blood sugar levels. Ratings on the glycemic index have resulted from numerous studies; however, individuals should test their own reactions to food in relation to the glycemic index.

The Glycemic Index and Food

Foods low on the glycemic index will release glucose gradually into the blood stream whereas foods high on the glycemic index will provoke an immediate response in the blood sugar levels. Foods that contain carbohydrates are usually high on the glycemic index and have the greatest effect on blood sugars. Pasta dishes, bread and potatoes are usually high on the glycemic index. The composition in the carbohydrate will also affect how the body?s sugar levels react. For example, white bread will rate high on the glycemic index whereas wholegrain or rye bread will be rate lower on the glycemic index as it contains more grains and contains complex carbohydrates. Examples of low glycemic foods are breakfast cereals (which are based on wheat bran, barley and oats), wholegrain break, fruit, lentils, soybeans, baked beans etc. Examples of high glycemic foods are white bread, soft drinks, full fat ice-cream, chocolate bars etc.

The Glycemic Index and Dieting

Health experts and dieticians contest that the glycemic index is difficult to use because it is complicated and will vary from person to person. They do concede however, that the glycemic index is a useful meal-planning tool especially when individuals monitor their own individual responses to foods. Low glycemic food is especially helpful in assisting those who want to lose weight. Low glycemic index foods will increase the sugar levels in the body to sustain energy levels for longer periods of time. This means an individual will feel less inclined to eat because energy is being slowly released into their bloodstream. A good understanding of the glycemic index will also assist with exercise. If you exercise then eating high glycemic foods will help you recover from your workout. Specifically, faster carbohydrates that are high on the glycemic index are great for raising low blood sugars after intense exercising whereas low glycemic index foods are helpful in maintaining blood sugar levels for long periods of exercise. Health experts encourage using the glycemic index in conjunction with other meal programs to assist in managing diabetes and/or controlling weight.
