In general, junk food is in a box or bag. It has preservatives so that it can sit on a shelf for months or even years. It contains many unpronounceable chemicals and lots of artificial colors and flavors. You won't find junk food growing in the ground, on a tree or displayed in the produce department at the grocery store. It is a manufactured substance which is cheap to buy and destroying the health of people....by the millions. The producers of such products are becoming very rich...."in the process"...no pun intended! Even knowing all of this and having health issues, most continue to buy it and eat it.

Junk foods typically contain high levels of calories from sugar or fat with little protein, vitamins or minerals. Foods commonly considered junk foods include salted snack foods, gum, candy, sweet desserts, fried fast food, and sugary carbonated beverages. ^[5] Many foods such as hamburgers, pizza, and tacoscan be considered either healthy or junk food depending on their ingredients and preparation methods.^{[citation needed]} The more highly processed items usually fall under the junk food category. ^[6] What is and is not junk food can also depend on the person's class and social status, with wealthier people tending to have a broader definition while lower-income consumers may see fewer foods as junk food, especially certain ethnic foods.
