"Snacks" are any foods or drinks that you take between regular meals. Snacks like fresh fruit are healthy snacks. However, if you don't choose foods or drinks carefully, snacking can become a bad habit and even harmful to your health. Eating less healthy snacks too often can also lead to health problems such as dental caries or overweight.

"Snacks" don't equal "Junk food", because snacks like fruits can give you energy and essential nutrients. Junk food is mostly "empty calories" - too much energy from sugar and fat but with few other nutrients. They are at the top of the Healthy Diet Pyramid.

So, you must check first, and choose healthy foods and drinks if you eat snacks. Snack in small amounts and only once or twice per day, but not throughout the day. If you're not hungry, there's no need to have a snack.
