In terms of meat consumption, the northern part of China is much higher than Europe and America, and there are many people. Secondly, meat food in Europe and America is more expensive. Ordinary families generally choose vegetarian food and eat meat on weekends or festivals. The food eaten in southern China is different. But it should not be less in Europe and America.

The staple food is rice and flour in China, and bread, milk and potatoes in Europe and America.

In terms of average food intake, Europeans and Americans must be much bigger than China. First, there is a gap in size. Second, in terms of eating habits, they are a set meal system, with one dish for each dish, while China eats them all together after serving.

The nutrition level of Europeans and Americans is much higher than that of China, because many cooking techniques in China destroy the nutrition of food raw materials, and many recipes in Europe and America are calculated on the basis of nutrition. Coupled with various factors of climate and soil, the quality of vegetables and fruits in Europe and America can't be compared with that of livestock in China, so their height and weight will be higher than that in China.
