fast foods and junk foods are very low in nutrient

Fast food and junk food are very low in nutrients; instead they are full with colorings, flavors and preservatives. You won't want to know how the unhealthy ingredients could lead to some severe mental disorders. Researches have shown that junk food might cause dyslexia, ADHD (attention deficit hyperactivity disorder) and worse is autism. An individual's mood and attention are highly influenced by the food taken, which means it will affect your concentration in school. For the parents out there, you won't want your children to be called as stupid in school, don't you?

Does that mean you can't have fast food and junk food at all? It is not necessary so. You just need to reduce the amount and frequency of having them in your diet. To begin with, you could bring your home-cooked food to your school or workplace. Of course, bacon, sausages and canned foods should not be your choices. Try some fresh foods and vegetables. You still can have your favorite fast food not too often; with the condition you drink a lot of water and exercise regularly.
