用英语单词或句子描述”junk food"

Junk food is a derisive slang term for food that is of little nutritional value and often high in fat,sugar,salt,and calories.It is widely believed that the term was coined by Michael Jacobson,director of the Center for Science in the Public Interest,in 1972.
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.Many foods such as hamburgers,pizza,and tacos can 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.
