There are 3 macronutrients in food, Fat, protein, carbohydrates and 3 types of micronutrients vitamins, minerals and phytonutrients. Carbohydrates are having maximum impact on blood sugar levels. Higher the amount of total carbohydrate in a food more blood sugar it will increase.
Carbohydrates are of 3 types, sugars, starches and fibers. Sugars will increase blood sugar faster than starches but fibers will not increase blood sugar. Depending upon the types of carbohydrates in a food it can be predicted that how much and how quickly blood sugar will increase. If 2 different types of food having same amount of total carbohydrate but one is having more fiber than other, then food with more fiber will have less impact on blood sugar because fibers are carbohydrates but they don’t get absorbed in blood hence they will not increase blood sugar. To know the impact of a food on blood sugar we calculate net carbohydrates.
Total carbohydrates minus total fibers is equal to net carbohydrates.
To understand the speed of blood sugar rise after eating a food we calculate glycemic index. The glycemic index (GI) is a ranking of carbohydrates on a scale from 0 to 100, based upon speed with which they raise blood sugar after eating. Foods with a high GI are those which are rapidly digested, absorbed and metabolized and result in high blood sugar levels. We consider glucose as standard and give him standard value of 100. Wheat flour is having glycemic index of 70. White sugar is having glycemic index of 65.
Low glycemic index food are good for diabetes because their blood sugar rise is less.
Glycemic load gives exact unit of blood sugar rise after eating a food. It is calculated on the basis of total amount of carbohydrates available in that portion of food multiplied by its glycemic index and then divided by 100.
1 glycemic load is equal to 1g glucose. 1g glucose is equal to 1 unit blood sugar rise.
The glycemic load of 100g wheat atta is 50. This means if a person eats 100g wheat atta (4 roti) then his blood sugar will rise by 50 points.
The glycemic load of diabexy diabetic atta nut and seed is 2.4, this means if a person eats 100g (4 roti) of diabexy atta his blood sugar will not rise much just 2.4 units. This is how all diabexy products are designed to not increase blood sugar much.
Daily glycemic load limit is the maximum amount of glycemic load allowed in your diet, this limit is prescribed by your doctor by looking at your situation. You must follow the daily limit set by doctor. You can easily calculate total glycemic load with the help of diabexy estimated glycemic load chart. Estimated glycemic load is mathematical calculation of glycemic load, this is not laboratory value.
Suppose you have eaten 100g cucumber and 100g curd then glycemic load count will be (EGL of 100g cucumber 0.37, EGL of 100 curd is 1.80) 0.37+1.80 = 2.17, this means your blood sugar increase is just 2 points.
NO, you should always consult your doctor before following restricted glycemic load diet because this diet will not increase your blood sugar. If you take diabetes medicine without much glycemic load then there is possibility of very low blood sugar caused by diabetes medicine which is called as HYPOGLYCEMIA. As you start on restricted glycemic load diet you will need very little medication or no medication depending on your situation hence you MUST consult your doctor before starting.
