For millions of adults and children, junk food and increased inactivity have led to obesity. 
Why Junk Food Is Bad For You?
For some people junk food has become a way of life, they are addicted to it and if everyone in your family, for example, eats junk food then it is very hard to eat healthily. But it is not impossible at all. So why junk food is bad for you?
There is so much talk about junk food. People know that it is unhealthy and makes people fat but what is the exact definition of junk food.
Well, Junk food is an informal term applied to some foods with little or no nutritional value, or to products with nutritional value but which also have ingredients considered unhealthy when regularly eaten, or to those considered unhealthy to consume at all. The term was coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.
Factors contributing to labeling as junk food are high levels of refined sugar, white flour, trans fat, and saturated fat, salt, and additives such as preservatives and coloring agents. Others include a lack of proteins, vitamins, fiber, and other nutrients for a healthy diet. Junk food is associated with health problems including obesity, heart disease, Type 2 diabetes, and dental cavities. Problems with fast food may not be apparent to children, hence advertising aimed at children has come under criticism.
Whole foods are the best nourishment for you. Make sure before you buy any foods, that you check the labels and ingredients. Even though the food label may say that it is low fat or reduced sugar, it still may not be healthier for you as some food companies add unhealthy ingredients to these foods to compensate for the low fat or sugar reduction in them.
When you buy bread, make sure that the label says �whole wheat flour� and not just �wheat flour� as it is not whole grain. Also, when you do eat out at a restaurant, you should ask what the fat and calorie content of the meals are and that way, you will not be consuming extra calories and fat needlessly.

Good eating habits also emphasize proper mealtimes instead of haphazard eating patterns. Snacking between meals on junk food like potato chips is one habit that can have a bad effect on teeth health. Many people including teens are addicted to consuming junk snacks and guzzling sugared soft drinks that are basically empty calories.
This has disastrous consequences for teeth health. It is estimated that the high sugar content of many junk food washes away protective teeth enamel, thus rendering them vulnerable to corrosive cavities. It is imperative, therefore, to completely shun fast food that corrodes teeth health and ushers in tooth decay.
