Glycemic Index - You NEED to know...

The glycemic index, glycaemic index, or GI is a measure of the effects of carbohydrates on blood sugar levels. Carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream have a high GI; carbohydrates that break down more slowly, releasing glucose more gradually into the bloodstream, have a low GI. The concept was developed by Dr. David J. Jenkins and colleagues[1] in 1980–1981 at the University of Toronto in their research to find out which foods were best for people with diabetes.
A lower glycemic response usually equates to a lower insulin demand but not always, and may improve long-term blood glucose control and blood lipids. A low-GI food will release glucose more slowly and steadily. A high-GI food causes a more rapid rise in blood glucose levels and is suitable for energy recovery after endurance exercise or for a person experiencing hypoglycemia.

Benefits of Low Glycemic Include:

◦Low GI diets help people lose and manage weight
◦Low GI diets increase the body's sensitivity to insulin
◦Low GI carbs improve diabetes management
◦Low GI carbs reduce the risk of heart disease
◦Low GI carbs improve blood cholesterol levels
◦Low GI carbs can help you manage the symptoms of PCOS
◦Low GI carbs reduce hunger and keep you fuller for longer
◦Low GI carbs prolong physical endurance
◦High GI carbs help re-fuel carbohydrate stores after exercise

A few tips to try Low Glycemic eating:
Pumpernickel Bread
Basmati, Brown or Long Grain Rice
Al Dente Pasta
Most Fruits and Vegetables
Oats, Barley and Bran
...Just to name a few to start!
