This is What Happens to Your Body if You Drink at Least 1 Coffee A Day

4. Reduces your risk of type 2 diabetes

Researchers at Harvard studied more than 100,000 people for nearly 20 years to find the correlation between coffee and the reduced risk of type 2 diabetes. What they found was that those who increased their coffee consumption by more than one cup per day had an 11 percent lower risk of developing the disease. They also found that those who reduced their coffee intake by one cup each day increased their risk of developing T2 diabetes by 17 percent.

While researchers don’t know the exact cause, they suspect it has nothing to do with caffeine, because the stimulant has actually been linked to a change in both glucose and insulin levels. And how your body reacts to the caffeine is really dependent on how your body metabolizes it. Either way, caffeine has found to be a negative factor on blood sugar, which leads experts to suggest that if you must drink coffee, make it decaf.
