An apple a day keeps the doctor away, or so the saying goes. A fresh apple is a suitable snack for people suffering from diabetesas it contains carbs and fibre, and is a good source of vitamin C. An apple as a snack helps to curb hunger between meals while adding nutritional value to the body. In fact, the skin of an apple is full of antioxidants which are essential to the human body. Apples also contain phytonutrients which help regulate blood sugar levels. Diabetics are therefore advised to carry an apple and snack on it in-between meals.
