From a historical point of view, people's living conditions in ancient times or in the last century were relatively difficult, and even the most basic problem of food and clothing was difficult to solve. Even starvation and frozen bones happen from time to time on the road. So for people in the past, it was a very happy thing to eat. "Being able to eat" here means being able to solve the problem of food and clothing. Now most people can pay attention to the collocation of food on the basis of solving the problem of food and clothing, so the saying that eating is a blessing is rarely mentioned now.
Furthermore, modern people may consume more calories than normal every day. Unable to hold their mouths and open their legs, many people and young people are obese and unhealthy. Therefore, what the mainstream advocates is to keep your mouth shut and take your legs. However, this has different views for different people. For example, people who have been thin can hear that eating more now is a blessing, not that you should eat less.
Eating is a blessing or eating less is a slogan that people pursue health. Fat people advocate eating less, while thin people advocate eating is bliss. The influence of diet on human health is very great, and the types of diet suitable for people of different ages are also different. Therefore, arranging our diet reasonably is one of the most important things in our life.
