Health Effects of High Glycemic Value Carbs

Research into the health problems of high glycemic value carbs is ongoing and we can expect new insights into the relationship between carbohydrates, blood glucose, insulin and obesity, in the future. Meantime, here is a brief outline of the health effects of high glycemic value carbs, to date.

High GI Foods and Health

  • High-glycemic-index foods trigger strong insulin responses, thereby exposing the body to all the negative effects of insulin. By comparison, low-glycemic value foods do not provoke this insulin response.

  • Diets containing high-glycemic-index meals, which cause rapid and strong increases in blood-sugar levels, have been linked to an increased risk for diabetes.

  • High-glycemic-index diets have also been linked to an increased risk for heart disease.

  • Lower glycemic index diets have been shown to help control type 2 diabetes and reduce symptoms of insulin resistance.

  • Over-consumption of high-glycemic-index foods has been linked to food cravings and disordered eating patterns, as a result of repeated surges and falls in blood-glucose ("sugar spikes").

  • Over-consumption of high-glycemic-index carbohydrates may aggravate insulin resistance in patients predisposed to the condition. Insulin resistance (called Metabolic Syndrome X, or more properly, Insulin Resistance Syndrome) is believed to be a precursor of type 2 diabetes.

  • Insulin resistance is believed to be a genetic condition, aggravated by obesity. However, some experts consider that it may be the result of a separate inherited sensitivity to high-glycemic-index carbohydrates.

  • Despite the apparent associations between high-glycemic-index carbs and insulin resistance, and the fact that the latter can be reduced by a lower glycemic index diet plan, there is no scientific evidence that insulin resistance is caused by eating carbs with a high-glycemic-index rating. Insulin resistance is largely the result of genetics, strongly influenced by body fitness and body weight.
