Zinc Promotes Healthy Blood Sugar Levels

A recent Harvard study suggests that higher zinc intake may reduce the risk of developing type 2 diabetes by up to 28%. Zinc is one of the body’s most important trace minerals, playing a role in numerous physiological functions. While it’s well known for supporting a healthy immune system, emerging research indicates that zinc may also influence memory, muscle strength, and endurance in adults.

The Harvard research followed 82,297 women aged 33 to 60 as part of the Nurses’ Health Study over a span of 24 years. After adjusting for other potential risk factors, the researchers found a clear association: women with higher zinc intake had a significantly lower risk of developing type 2 diabetes.

In the United States, more than 20 million people are affected by diabetes—about seven percent of the population. According to the American Diabetes Association (2002), the total economic burden is estimated at $132 billion, with $92 billion attributed to direct medical costs.
