Can caffeine affect your blood sugar levels? Here are some details diabetics should not miss.

Diabetes: Can caffeine affect blood sugar levels?

What you eat directly affects your blood sugar levels. Several studies suggest that drinking coffee can reduce the risk of developing diabetes. If you already have diabetes, the effect may vary from person to person. Some may have a positive effect while others can experience increased blood sugar levels. The effect also depends on the quantity of the caffeine consumed. If your blood sugar levels are already out of control, you should reduce caffeine intake, especially with added sugar and cream. Caffeine consumption in moderation can be healthy for diabetics.

Dietitian Upasana Sharma, Head Nutritionist at Max Hospital explains, "Coffee is a very common beverage. According to studies, if a healthy individual consumes coffee in moderation it can reduce the risk of developing diabetes. But if the person is already suffering from diabetes, coffee consumption can contribute to fluctuations in blood sugar levels. Ideally, diabetics should avoid coffee. They can opt for decaffeinated coffee without sugar."
