Diabetics have got to be more careful than other people when it comes to their food habits, and there are some certain super foods that are particularly good for them. One of the best ones is dark chocolate because it's rich in flavonoids which are capable of reducing insulin resistance, improving insulin sensitivity, dropping insulin levels and fasting blood glucose. But apart from all the benefits that dark chocolate has for diabetics, it can also lower the risk of suffering a stroke, it can calm blood pressure and, very importantly reduce your risk for a heart attack.
