junk food
Junk food is a pejorative term for food containing high levels of calories from sugar or fat with little protein, vitamins or minerals. Use of the term implies that a particular food has little "nutritional value" and contains excessive fat, sugar, salt, and calories.〔(【引用サイトリンク】 title=junk food )〕〔(【引用サイトリンク】 title=junk food )〕 Junk food can also refer to high protein food like meat prepared with saturated fat -which some believe may be unhealthy; many hamburger outlets, fried chicken outlets and the like supply food is considered as junk food.〔(Fast Food Facts )〕
Despite being labeled as "junk," such foods usually do not pose any immediate health concerns and are generally safe when integrated into a well balanced diet. However, concerns about the negative health effects resulting from the consumption of a "junk food"-heavy diet have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries.
== Effects of Fast Food ==
A third of the United States eat fast foods daily. The alarming figures are not alarming given the extent of advertising and the billions spent for the commercials on fast foods. Findings indicate that since 1970, the consumption of fast foods has increased five-fold. The lovers of fast foods consume more sugars, fats and carbohydrates, leaving out fruits and the non- starchy vegetables from their meals. These people also consume more calories that it is required. Unhealthy fast foods are negatively affecting the population, specifically making children obese and other people fat. For instance, a study by Jaworowska et al (315) concluded that, “some of these frequently consumed foods may contribute to a variety of negative health outcomes, including cardiovas- cular disease, insulin resistance, type 2 diabetes, and obesity."
