Junkfood

Junk food is an informal term for food that is of little nutritional value and often high in fat,sugar, and calories.[1][2][3]
It is widely believed that the term was coined by Michael Jacobson,director of the Center for Science in the Public Interest, in 1972.[4]
Junk foods typically contain high levels of calories from sugar or fat with little protein,vitamins or minerals. Common junk foodsinclude salted snack foods, gum, candy, sweetdesserts, fried fast food, and carbonated beverages.A study by Paul Johnson and Paul Kenny at the Scripps Research Institute (2008) suggested that junkfood consumption alters brain activity in a manner similar to addictive drugs like cocaine or heroin.[6] After many weeks with unlimited access to junk food, the pleasure centers of rat brains becamedesensitized, requiring more food for pleasure. After the junk food was taken away and replaced with a healthy diet, the rats starved for two weeks instead of eating nutritious fare.[7] A 2007 BritishJournal of Nutrition study found that female rats who eat junk food during pregnancy increased the likelihood of unhealthy eating habits in their offspring.
too much fat! Junk foods such ashamburgers, 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 arisk to the health of the heart and can cause other diseases.Too much salt! Junk foods often have too much salt. There's a lot of salt already in foods such as bread, breakfast cereals and biscuits andcakes. So people are getting more salt than they need when they eat junk food. Too much salt is unhealthy for the heart. Too much sugar! Soft drinks, cordials, biscuits, cakes and lollies all haveloads of sugar. That's what makes them taste so good! But too much sugar makes people fat, rots the teeth, is bad for the blood and may cause other diseases.Should people eat junk food?
