Can High Glycemic Foods Derail Your Health?
On our journey for living to be 100, we must take into account the glycemic index (GI) of foods for us to choose foods wisely. The glycemic index refers to the rise of blood sugar after eating certain foods, particularily carbohydrates. Fats and proteins don’t cause a really significant rise in blood glucose levels. The glycemic index tells us how rapidly carbohydrates turn into glucose. Glucose has a GI value of 100, and the glucose in other foods is compared to it.
For example, a donut has a glycemic index of 76, whereas a serving of black-eyed peas has a value of 41. The Glycemic Index Guidelines are:
GI of 70 or more is considered high. Examples are pretzels and white bread.
GI of 56 to 69 is considered medium. Examples are brown rice and popcorn.
GI of less than 55 is considered low. Examples are orange juice and most fruit and vegetables.
Some researchers place even more emphasis on the glycemic load (GL) rather than the glycemic index. The glycemic load takes into account the amount of carbohydrates there are in a certain food while the glycemic index tells how quickly a carbohydrate turns into blood sugar. The higher the glycemic load value, the greater the blood sugar level and the resulting spike in insulin levels.
To arrive at the glycemic load, multiply the amount of carbohydrates in a serving of food by the glycemic index of that food and divide by 100. For example, an apple has a glycemic index of about 40 and has about 16 grams of carbohydrates. This gives a value of 640. Divide this by 100 and the glycemic load is 6. Below are glycemic load guidelines:
GL of 20 or more is considered high
GL of 11 to 19 is considered medium
GL of 10 or less is considered low
High blood glucose levels are associated with diseases such as diabetes, atherosclerosis and others. On our mission of living to be 100, we want to avoid foods that promote disease by causing insulin spikes from high glycemic-producing foods.
