The Glycemic Index tells the difference between Bad Sugar and a Good Sugar
Carbohydrates are one of the best sources of energy for our body. The simplest sugar is a glucose, which is:
- the universal fuel for most of the organs and tissues in the body
- the only source of fuel for the brain and red blood cells
- the main source of energy for our muscles during intense exercise.
However, products containing easily digestible sugar, reach the bloodstream in short time and raise the level of glucose rapidly.
Here comes the Glycemic Index, the best dietary tool that allows you to differentiate between good and bad carbs.
Carbohydrates with low glycemic index (55 and below) cause a controlled increase in blood glucose levels, providing the body with energy for longer. Where are those carbohydrates? In most vegetables, fruits, legumes and whole grain products. These products also are rich in carbohydrates, but complex carbohydrates are being absorbed slowly into the bloodstream during digestion.
Carbohydrates with high glycemic index (70 and above) cause a rapid increase in blood glucose levels, which results in the release of large amounts of insulin, the hormone responsible for the absorption of glucose from the bloodstream into the cells. Following, rapid decrease in blood glucose causes hunger. This group includes highly processed food products that contain fast absorbing sugar for example white bread, white pasta and rice, cakes, ice cream, chocolate bars, candy, popcorn, beer, sugary sodas.
