The west is a rational and scientific concept of diet. They emphasize the nutritional value of diet, pay attention to the amount of protein, fat, calories and vitamins contained in food, and pay special attention to whether the nutritional content of food is appropriate, whether the calorie supply is just right, whether these nutrients can be fully absorbed by consumers and whether there are other side effects. They try their best to keep the original flavor and natural nutrition of food, instead of pursuing the perfection of color, fragrance, taste and shape of food. Even if the taste is the same, even the same as chewing wax, they will eat it. Westerners eat nutrition. They rarely or hardly associate diet with spiritual enjoyment. It reflects the strong practical and utilitarian purpose in diet. Westerners believe that diet is only a means of survival to satisfy hunger, but it adopts a more scientific, standardized and reasonable way. For example, their primary and secondary schools are equipped with nutritionists to ensure that teenagers get adequate and balanced nutrition. This scientific and reasonable diet concept is worth learning from Chinese food. But at the same time, this makes western food greatly limited in materials. For example, westerners don't eat animal offal. They think that everything has no nutritional value. At the same time, it is mechanical and inflexible in cooking skills. Steak is steak and chicken is chicken. Vegetables will never be mixed together, nor will they produce many patterns.

To sum up, it is a sentence: Westerners emphasize science and nutrition in their diet.
