Zinc, like magnesium, gets shipped out of a diabetic’s body through urine when blood sugar levels start to climb. This results in zinc levels dropping to dangerously low levels in people with diabetes.
This is a significant problem because zinc plays an important role in producing the specific hormone that regulates the amount of glucose in the blood. When zinc levels plummet, blood sugar levels can get out of control, increasing the chances that a diabetic will suffer serious complications. For this reason, doctors often recommend diabetics take zinc supplements or eat foods like beans, nuts, seeds and soy, which are high in zinc.
