Some Facts On Glycemic Index You Need To Know

By Betty Brown


Diabetes is a leading metabolic disorder related to both genetics and lifestyle. The main underlying problem is insufficient production of insulin hormone or inability of the body to make use of this hormone (also known as insulin resistance). Diet modification is one of the ways that can be used to reduce the risk of developing diabetes as well as minimize associated complications. You need to understand the glycemic index of foods in order to make good dietary decisions.

The index is expressed numerically. The higher the number, the higher the potential of a given type of food to increase the levels of blood sugars. The general advice is that people who are at risk of diabetes or those already suffering from the condition should have less of foods that will increase their blood glucose levels and more of those with a lower index.

Foods that have been allocated a value of 55 or lower are generally considered healthy. Those with values ranging between 56 and 69 are put in the medium category meaning that the increase that results is modest. High values are those that are 70 and above. Foods in this category should be avoided as much as possible. It is possible for foods with the same carbohydrate content to have different values.

Several factors have been found to affect the level of the index. Food preparation methods appear to have the greatest influence. If foods made of starch are cooked over a long period of time, their glycemic value increases. On the other hand, when fats, acids and fiber are added to foods, the value has been shown to reduce. Ripeness is another important factor; fruits that are riper have a greater influence on glucose levels.

The index has to be considered alongside other factors when making the choice for foods to be consumed. This is because in some situations its value may appear high making the foods undesirable yet the foods in question have a high nutritional value as a result of a high level of minerals and vitamins. The portions that are served also influence the degree to which blood glucose will be elevated.

Various foods have been shown to have fairly low indices. They include legumes, grains, nuts and vegetables among others. Since carbohydrates are a direct precursor of glucose, they have a high glycemic diet. Examples include white rice, white bread and potatoes. The highest values will be seen with sugary and processed foods such as cakes, candy and cookies.

Naturally occurring foods and those that are very close to their existence in nature tend to have lower values that those that have been through some form of processing. Even with this knowledge, one needs to always read the food labels and make sure whatever they are buying is healthy. In the event that you have any doubts then the wisest thing to do is to contact your nutrition counselor.

As you work towards achieving a healthier diet, be careful not to starve yourself. Diabetics not only have to worry about high blood sugar levels but the other extreme as well which is hypoglycemia. If the amount of calories is too low in the diet then the risk of slipping into hypoglycemia increases. This may lead to a reduction in the level of consciousness and even coma.
