What You Need To Understand About The Glycemic Index

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 value of the index is expressed as an absolute number. Foods that have a high value have a higher potential to increase the level of blood glucose. Those that have a lower value, on the other hand, increase the levels of marginally. The general advice is that persons that are at risk of suffering from diabetes or have already been diagnosed with the condition should have foods that have a low value.

Food is said to have a low index if its allocated value is 55 or lower. Foods in this category are regarded as being healthy for diabetic patients. Those that have values of 56 to 69 fall in the medium category and those that have a value of 70 or more are considered as having a high value. These typically cause spikes in sugar levels as soon as they have been eaten. They should, therefore, be avoided as much as possible.

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 should not be the only thing to consider when choosing what to eat. The nutritional value of the food should also be thought of as the decision is being made. Although some foods have relatively high values, their inclusion in the diet is important due to a higher value of minerals and vitamins. The portion size of food consumed matters as well. Larger portions increase the sugar levels more than smaller portions.

Nuts, grains, fruits and vegetables are among the foods that have been shown to have the lowest values of the index. High values will be seen with most starch-based foods such as cakes, cookies and candy. Even higher values result after the intake of highly processed and sugary foods such as cookies, cakes and candy. This group increases the levels of glucose sharply after they have been consumed.

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.

Even as you strive to have a proper diet be careful not to starve yourself. The changes in blood sugar levels among diabetic patients can swing in either direction and lead to potentially life threatening complications. Denying yourself much needed calories can lead to episodes of low blood sugar (or hypoglycemia). Severe hypoglycemia can cause loss of consciousness and even a coma if not addressed in time.
