This is the most common mistake that we all do on a regular basis. To control the blood sugar from rising rapidly, it is important that you combine carbs with some other nutrients like protein, fibre and fats. Eating just carbohydrates will just release sugar into your bloodstream and there will be no gain of nutrients. However, when it is combined with protein & fibre along with fats, it slows down the process of releasing sugar in the bloodstream as the body takes time to digest these nutrients.
