The Glycemic Index looks at the effects of carbohydrate-containing foods on sugar levels in your bloodstream. Whenever you eat and digest carbohydrate-rich foods - foods like fruits, vegetables, grains and sweets - the end result is a rise in your blood sugar (your blood glucose). This sugar in your blood is important - it's the primary fuel for your brain and muscles and is, in large part, what keeps you going mentally and physically throughout your day.
But not all carbohydrate-containing foods cause your blood sugar to rise to the same degree - and this is where the Glycemic Index (or GI) comes in. The GI ranks foods according to how much - and how rapidly - they cause the blood sugar to rise after they're eaten.
Foods with the highest Glycemic Index
(low in fiber, but starchy or sugary)
|
Foods with Low Glycemic Index
(carbohydrate-rich foods that are whole and unprocessed)
|
White bread
|
Most 100% whole grain foods: rolled oats, barley, quinoa, 100% whole grain bread
|
Sweet breakfast cereals
|
Vegetables
|
Noodles
|
Beans
|
Fruit Juices
|
Whole Fruits
|
White rice
|
Brown rice
|
|
|
* Since they are digested and absorbed relatively quickly, these high Glycemic Index foods tend to cause fairly large and rapid rises in blood sugar.
|
*High in fiber - which means they take longer to digest - and so your blood sugar rises more gently after you eat them

Note: Formula 1 Nutritional Shake Mix is low GI tested.
Adjusting the Glycemic Index of your diet
To cut back on your high GI foods and reduce the carbohydrate load of your diet overall, here are some switches you can easily make.
Instead of this:
|
Have this:
|
White Rice and Potatoes
|
Brown Rice and other whole grains like cracked wheat, barley, millet or quinoa or substitute beans, lentils or sweet potatoes
|
Fruit juices
|
whole fresh fruits - have berries on cereal, or a whole piece of fruit for a snack or dessert
|
Refined white breads, crackers and snack foods
|
|
Whole and lightly processed low GI foods are more bulky and filling than their refined cousins, which means they retain their natural vitamins, minerals and healthy antioxidant phytonutrients, too. And that means that you get more nutrition for your calories. By swapping out the high Glycemic Index foods and replacing with more low GI items, you can greatly reduce the overall carbohydrate load of your diet - which can help you with calorie control while providing a healthy nutrient boost, too.
