Why is an apple a healthier snack than a chocolate bar?
An apple is a healthier snack because it has more nutritional value than chocolate — and a fraction of the calories.
Apples contain vitamins and minerals that are essential to healthy growth and development, as well as brain functioning, heart health, and our bodies' other daily needs. Apples are also high in fiber, which can help you feel full and discourage overeating. Combine an apple with protein, such as a stick of low-fat string cheese or a tablespoon of peanut butter, and you have a perfect snack for long-lasting energy and good health.
Chocolate, on the other hand, has relatively little nutritional value but a lot more calories (thanks to all the sugar and fat). So it's best to make chocolate an occasional treat, instead of a regular snack.
