Drinking coffee or tea is a daily ritual for millions, but for people with diabetes, the choice can feel complicated. Research suggests both beverages have health benefits, but their impact depends largely on how they are prepared and consumed.
Coffee and Diabetes
Studies indicate that regular coffee consumption may slightly reduce the risk of type 2 diabetes. Coffee is rich in antioxidants and chlorogenic acid, which can improve insulin sensitivity.
- Benefits: Black coffee is almost calorie-free, making it unlikely to cause weight gain.
- Risks: However, adding sugar, cream, or sweetened milk to coffee significantly raises blood sugar levels, making it less suitable for diabetics. Overconsumption can also lead to an increased heart rate and disrupted sleep.
Tea and Diabetes
Green tea is known for its catechins, compounds that can improve insulin efficiency and support weight control. Black tea and herbal teas also provide antioxidants that boost heart health.
- Benefits: Tea generally contains less caffeine than coffee, making it a safer option for those with heart or blood pressure concerns.
- Risks: Just like coffee, milk tea with added sugar can be harmful for people managing diabetes. Some herbal teas may also interact with certain medications, such as blood pressure drugs or blood thinners, so it’s wise to be cautious.
The Bottom Line
Both coffee and tea can be beneficial for diabetics when consumed in moderation and without added sugar. While coffee supports insulin sensitivity, tea offers heart health benefits and lower caffeine levels. The decision ultimately depends on an individual’s health and how the beverages are prepared. For diabetics, simplicity and balance—like plain black coffee or unsweetened tea—remain the safest choices.
