Monks usually eat more beans instead of meat to supplement protein, but plant protein can't completely replace animal protein.

Protein in animal foods, such as lean meat, milk, eggs, fish, etc., contains 8 kinds of essential amino acids, and the amount is relatively large. All kinds of amino acids have proper proportions, and their biological characteristics are close to that of human body, that is, they are very similar to the protein structure of human body and are easily digested and absorbed by human body.

Among plant foods, protein in soybeans and oats belongs to high-quality protein, while protein in other plants such as rice, flour, fruits, beans and vegetables belongs to non-high-quality protein, and its amino acid composition is not comprehensive enough. Even the high-quality protein in soybeans and oats still lags behind the protein in eggs, milk, fish and meat.

What are the adverse consequences of the lack of protein in human body? 1. Growth retardation, anorexia, picky eaters, indigestion and emaciation; 2. Memory loss, inattention and poor efficiency in study and work; 3. Low immunity, insomnia and dreaminess, low mood and easy fatigue; 4. Trauma is not easy to heal, postpartum body recovery is slow, and recovery after illness is slow.

The harm of vegetarianism

Vegetarian diet is more likely to lead to high blood sugar.

Under the premise of the same calorie intake (for example, 2000 kcal), the proportion and total content of carbohydrates in vegetarian diet are more than those in vegetarian diet, and carbohydrates are the most important reason for the increase of blood sugar. From this perspective, vegetarians are at greater risk of developing hyperglycemia.

Because they can't get energy from protein and fat in meat, vegetarians can only supplement it from rice, pasta and other foods, which often leads to excessive carbohydrate intake, thus leading to the risk of hyperglycemia.

Vegetarianism all the year round leads to micronutrient deficiency.

Micronutrients, that is, minerals and vitamins, are nutrients that the human body needs less, but they are necessary for survival, growth and development, physical activity and health.

Take iron, the most abundant essential trace element in human body, as an example: compared with western countries, China is a region with high incidence of iron deficiency anemia. It is believed that the reason is that China residents mainly eat plant food, and more than 85% of iron intake comes from plant food.

Iron in plant food is non-heme iron, and its actual absorption rate is very low, usually less than 5%. There are also zinc, selenium and B vitamins ... If you don't eat meat, these trace elements can't be taken from other foods.

Vegetarianism all the year round will increase the burden on the stomach.

Vegetarian food contains less calories than animal food. In order to achieve satiety and maintain human activity, you will unconsciously eat more food to make your stomach squirm. When the gastrointestinal tract is overwhelmed, the risk of illness will increase.
