If you get the right energy and nutrient balance and make sure your diet contains plenty of fruit and vegetables, together with wholegrain carbohydrates and a modest amount of protein and fat, there's room for you to enjoy a variety of foods, including treats. But it's important to remember that treats should remain treats and should not replace main meals.
