Single food, lack of nutrients
Each food has its own characteristics, such as high carbohydrate content in cereals, high protein content in eggs, high fat content in meat, and high vitamin content in vegetables and fruits. No food in the world contains all the nutrients needed by the human body. Three meals a day for a long time will cause nutrient deficiency and affect human health. The dietary guidelines for China residents issued by the Nutrition Society of China pointed out that foods should be diversified, and diversified diets can obtain more nutrients to maintain human health.
The food is single, and it is difficult to satisfy the desire for food.
Eating is the biggest thing in life, and we need to eat a lot of food in our life. Different foods have different methods, and these foods have different tastes. Perhaps you have seen a person drive dozens of kilometers to buy a certain food, which is to satisfy his desire for this food. And a single diet makes it difficult to satisfy the desire for food and reduces the fun of life. The reason why there are so many gourmets, and the public is willing to spend money to buy some food courses, lies in their love for food. Not only can you taste the delicious food, but you also enjoy the happiness in the production process.
Single food leads to health problems.
Nowadays, all kinds of chronic diseases are commonplace, and diabetes is not surprising. For diabetics, a large part of the reason lies in a single diet. The staple food is the main source of body energy. Most people eat white-flour steamed bread made of refined white flour, and the refined flour loses more dietary fiber and B vitamins in the production process. If diabetics change their staple food into steamed bread made of coarse grains or rice made of coarse grains, their blood sugar will be more stable after meals.
