Question: 1 / 650

Which mineral deficiency can lead to poor glycemic control?

Copper

Selenium

Chromium

A deficiency in chromium is directly linked to poor glycemic control. Chromium plays a crucial role in carbohydrate metabolism and insulin sensitivity. It enhances the action of insulin, the hormone responsible for regulating blood glucose levels. When chromium levels are inadequate, the body's ability to utilize glucose efficiently is impaired, leading to fluctuations in blood sugar levels and contributing to conditions such as insulin resistance and type 2 diabetes.

In contrast, while other minerals like zinc, selenium, and copper have important roles in various metabolic processes, their direct implications on glycemic control are not as pronounced as that of chromium. Zinc, for instance, is important for insulin storage and release, but its deficiency does not have the same clear connection to glycemic control as chromium does.
