How do I calculate the glycemic index?
The calculation of the glycemic index (GI) is generally considered to be a difficult task, and therefore scientists and nutritionists have compiled a glycemic index of many common foods. Mathematical equations allow a person to calculate glycemic food index in food if carbohydrates are known in every meal and glycemic index for every meal. Numerous websites offer a list of total glycemic food index numbers that help calculate the glycemic index; There are also websites that offer common fast food numbers. When using this website, it may be typical to find not only a glycemic index, but also the size of a portion in grams, carbohydrates on portion and glycemic load (GL).
Although similar, glycemic loads and glycemic index are two completely different measurements. A glycemic index is a rating system that measures how fast a specific carbohydrate breaks into sugar in the human body. On the other hand, glycemic loads not only measures but also measure how many carbohydratesHe's in food. For example, melon has a high GI, but low GL. The reason is that the watermelon turns into sugar quickly in the digestive process, but there are not many carbohydrates in the real fruit.
When GL is known, the person can calculate the glycemic index by multiplying a glucose load of 100. This number is then divided by available carbohydrates measured in grams. Available carbohydrates are defined as the total carbohydrate content of minus fiber content. The result is a glycemic food index.
For calculating a glycemic food index, add total carbohydrates throughout the meal and then look for GI for each carbohydrate. Once you find out how many carbohydrates have been consumed in each portion, take the number of carbohydrates in the serving and divide it with the total number of carbohydrates in the group. The result will be the percentage of carbohydrates that the group contributed. This number can then be multiplied by glycemic index for a group of carbohydrates. Finally, you can add all these numbers together and the result will be a glycemic index for food.
The calculation of the glycemic index for a particular meal is almost impossible for a person without the help of glycemic burden. The best way to find these numbers is to find a list created by scientists and nutritionists. These lists can help people calculate glycemic food index. Foods with low glycemic index help reduce the risks of heart disease and diabetes and can help control existing diabetes.
