Proteins are necessary for tissue repair and for the construction of new tissue. Every cell needs protein to maintain its life. Protein is also the primary substance used to replace worn out or dead cells. Your muscles, hair, nails, skin, and eyes are made of protein.

Thus, as my old clinical nutrition professor pointed out, apparently a chromium deficiency can actually lead to type II diabetes.
Vinegar, green tea, nuts, and spices are among the foods that increase insulin sensitivity, improving the bodyâs ability to store the carbs you eat as muscle glycogen instead of as fat. For example, vinegar improves pancreatic function so that your body releases less insulin in response to the carbs you eat.
