People may think that any food that is low in fat is inherently healthy. This is not the case! For example, soda and hard candy have no fat, but they also have no vitamins, minerals, fiber, or other health-promoting ingredients. What they do have is sugar, and lots of it. And a lot of sugar can add up to a lot of calories.

Eating foods high in sugar and calories can lead to weight gain, and being overweight is a risk factor heart attacks and heart disease.

In addition, sugary foods often take the place of healthier foods. For example, when was the last time you chose a soda over a glass of skim milk or snacked on gummi bears instead of an apple?
