Digested quickly and provide quick energy that does not last
Should be limited to small quantities
Provide calories, but few vitamins and minerals
Sources: table sugar, products with white flour, honey, milk, yogurt, candy, chocolate, fruit, fruit juice, cake, jam, biscuits, molasses, soda and packaged cereals
