Diabetics have to think twice before they indulge in their favourite fruit treats. Nutritious yet high glycaemic fruits like bananas pineapples and watermelons do have a dubious reputation of causing a spike in blood sugar levels. But a good dose of fruit is important for diabetics from an overall health perspective. Fruits provides essential micronutrients and fibre which keeps the body healthy. Instead of omitting them completely out of your diet diabetics should try to include low and medium glycaemic fruits like apples strawberries and oranges in their diet. One of the best fruits for diabetics is the dragon fruit.
