.mmon phenomenon. It is only in the last hundred years that humanity has just solved the problem of food deprivation,this is the first time in the long history of evolution.
From then on, people who waste food will no longer suffer from food deprivation, however, the health of people who accumulate lot of fat will be affect because of excessive intake of food.
When humans no longer worry about eating, "taste" has become a major factor affecting food preferences. On the one hand, the "sweet" is the human favorite taste, there are statistics found that children's food preferences are about 50% depending on the sweetness. On the other hand, a lot of flavor substance is dissolved in the fat, so the fat to eat more meat stuffing.
