Beginning in the 1980s, consumer awareness of the importance of glycemic index and how it affects consumer's lives has increased substantially.
In fact, many celebrities have openly discussed their diabetic conditions on television talk shows and have revealed how a change in their eating habits specifically with low glycemic foods has been beneficial for their overall health. Because of this increasing public awareness there has been an increased buying trend for low glycemic foods.
This consumer awareness has reached out of the United States as the European and Australian governments have been actively involved in the promotion of glycemic index foods.
There are multiple ongoing medical studies regarding the impact of glycemic index with diseases such as diabetes, rheumatoid arthritis, multiple sclerosis, Crohn's disease, cancer, etc.
Studies from the Harvard School of Public Health have already shown the correlation between the risk of type II diabetes and coronary heart disease with the glycemic index of the consumer's diet.
These studies have shown that simple carbohydrates are easily and quickly utilized by the body because of their simple chemical structure. This leads to a faster rise in the blood sugar and insulin secretion from the pancreas which can have negative health effects.
The consumption of high glycemic index foods which causes elevated spikes in blood sugar can lead to increased risk for type II diabetes, heart disease, and obesity.
The preliminary data from these ongoing studies have shown an increased risk of age-related macular degeneration, infertility and colorectal cancer from a high glycemic diet. A recent 2014 study showed the importance that a low glycemic diet has as an anti-inflammatory benefit.
In 1999, the World Health Organization and the Food And Agriculture Organization recommended that people in industrialized countries base their diets on low Glycemic Index foods in order to prevent coronary heart disease, diabetes and obesity.
The European Association for the Study of Diabetes has recommended that people with diabetes choose food with a low glycemic index.
