Coffee can have various effects on the body including thins like the jitters when you drink too much coffee, and headaches and fatigue when you drink too little. Usually these problems are not very serious, but coffee may very well have some other, more serious effects on the body.
Caffeine and Insulin Resistance
The main culprit in coffee seems to be caffeine, since it can have a huge affect on the body and its functions. Studies suggest that the caffeine in coffee may make the body less sensitive to insulin, which means that the insulin cannot function as it should. It appears to be the caffeine in the coffee, since decaffeinated coffee did not have the same effect.
Whilst coffee alone may not cause insulin resistance, it may have a contributing effect and the best advice would be to cut back on the java. Whether you have insulin resistance or not, taking the Manna Blood Sugar Support supplement with each meal can help to control blood sugar levels and also help your body to be more insulin sensitive.
