When it comes to managing diabetes, both coffee and tea have their own benefits and potential drawbacks. Coffee contains antioxidants and has been shown to improve insulin sensitivity, which can help in managing blood sugar levels. However, it can also cause spikes in blood sugar for some people due to its caffeine content. On the other hand, tea, especially green tea, is rich in antioxidants called catechins, which have been shown to improve insulin sensitivity and reduce blood sugar levels. Additionally, tea generally has less caffeine than coffee, which might make it a better option for those sensitive to caffeine. It's important to note that adding sugar, cream, or other sweeteners to either coffee or tea can negate their benefits and lead to increased blood sugar levels. Therefore, it's best to consume these beverages in their purest forms. Always consult with a healthcare provider to determine what works best for your individual health needs.
