Junk Food or ' Junk Eating'?

摘要

Despite the widespread epidemic of overweight and obesity, little attention has been given until recently to the potential of 'junk foods' in its causation. This essay discusses the role of 'junk food' in nutrition-related disorders and some associated factors that affect this problem. It also considers whether 'junk foods' are intrinsically unhealthy, whether their pattern of consumption is contributory, and whether the term 'junk eating' is useful.Junk food or junk eating and lowered exercise patterns have been linked to the steep rise in overweight and obesity, which has become 'a public health crisis', particularly in industrialized and industrializing countries, over recent decades [1, 2]. However, there is limited objective evidence of the potential contribution of 'junk foods' or 'fast foods' and/or mechanisms by which they may promote excessive weight gain.
