The glycemic index (GI) is a scale from 1-100 that ranks carbohydrate-rich foods by how much they raise blood glucose levels.
Some carbohydrate foods are digested quickly, and others more slowly.
The ranking is based on how the carbohydrate food when digested compares to the standard food, which is either white bread or pure glucose.
White bread and glucose have been given the highest possible rating of 100 on the glycemic index because they raise blood glucose levels higher and quicker than most other foods. A food that has a high glycemic index ( 70 or more ) will increase your levels of blood sugar more quickly than one that has a medium or low GI ( 55 or less)
BLOOD GLUCOSE LEVEL AND GLYCEMIC INDEX:
HIGH GLYCEMIC INDEX DIET AND INFLAMMATION
Today, 85-90% of the carbohydrates adults and children are consuming in the US and Canada are highly processed and high-glycemic.
Foods like bread, cereal, and potatoes actually spike your blood sugar faster than eating pure table sugar!
A high glycemic food increases blood sugar concentrations quickly! The body has energy only for a short period of time. Insulin is release in response to this rise to blood sugar, which in turn, brings the glycemia down rapidly.
