The glycemic index is a scale which indicates how quickly a food is converted into glucose in the blood stream. Foods are assigned a number with glucose being 100. The higher the number, the faster a food will be converted to glucose. This is dependent upon the level of training. Excessive dietary protein can be taxing on the kidneys.
Protein metabolism produces nitrogen which is processed by the kidneys.
Overloading the kidneys with nitrogen waste may lead to kidney disease. High-protein diets can also cause dehydration. To calculate protein requirements multiply your weight in kilograms by 1.6 to 2.4. Dairy products are also good sources with an average content of eight-nine grams per cup. Beans and legumes are good sources containing approximately six-eight grams per half cup.
