There are several studies around the impact of coffee on Diabetics. While, one study shows that drinking coffee once in a while can lead to insulin resistance, whereas the other research reflects that drinking coffee without added sugar and milk can help in managing the sugar levels naturally. However, more research is needed to establish the impact of drinking coffee on Diabetics.
In fact, as per some studies, it is believed that caffeine can improve insulin sensitivity and eventually reduce sugar levels. According to FDA guidelines people with Diabetes must go for moderate coffee intake to reap the benefits and manage sugar levels naturally.
