There is a group of metabolic diseases, according to Diabetes Mellitus, where an individual has high blood glucose, either because the cells don’t respond properly to insulin or the production of insulin is inadequate, or in some cases both.
The diabetes can cause serious health problems like lower-extremity amputations, kidney failure, blindness and heart disease.

We should all worry about the levels of blood sugar as if it is high for longer period it can lead to serious health disease or diabetes. Physical inactivity, stress, genetic predispositions, smoking, drinking soda and consuming a lot of sugar are the main reasons for high blood sugar. The most common symptoms of type 2 diabetes are weight gain, impotence, yeast infections, wounds that do not heal, feeling worn out, numbness or tingling in the feet or hands, being irritable, blurry vision, peeing a lot, dry mouth and being very thirsty.

The glycemic index (GI) measures how the foods that contain carbs raise the blood sugar. It uses a 0-100 scale. The higher the ingredient’s value is, there is more rapid rise in blood glucose.
