The term “junk food” is used to describe food which is low in nutritional value, with a comparatively high caloric value. Many people try to avoid or limit junk food in their diets, out of concerns that such food is not healthy, despite the fact that numerous food manufacturers produce a range of products which could be considered junk food. Nutritionists, doctors, and other health advocates often work to educate people about junk food, encouraging them to eat well balanced diets which contain a high proportion of healthy foods.
Junk foods such as hamburgers, pizza, fried chicken and chips usually contain loads of saturated fats. Too much saturated fat in the diet will cause people to put on weight and get fat or obese (very fat). Being overweight is a risk to the health of the heart and can cause other diseases.
