Summary: Plant protein seems to be better for cardiovascular health and weight loss, while animal protein has an advantage in obtaining quantitative nutrition through a small amount of intake (food). For vegetarians, there is no need to worry about malnutrition caused by only supplementing plant protein (of course, the premise is to consume a variety of fruits and vegetables).

When it comes to protein supplementation, the most common way to think of is to drink milk, eat eggs, and eat meat. Supplementing protein through plants is obviously not what most people can think of.
So is plant protein better than animal protein?
“Protein and Amino Acids”
Popular science here-
After being absorbed by the human body, protein is converted into amino acid, which can re-produce protein for body cells and improve metabolism in the body. Its synthetic glutathione has high antioxidant function.
Essential amino acids (referring to the body cannot be synthesized or the synthesis speed cannot meet the needs), and need to rely on external supplements (food intake).
“Comparison of protein quality”
Through the following three points of comparison-
1. Protein content in food
The protein content of meat, fish, and shellfish is about 15% to 25%
The fat (fat part) is only about 2%
Egg protein is slightly lower, 10%-14%
Milk has the lowest protein content, 1%-5%
The soy protein content is as high as 40%
Nuts such as peanuts, walnuts, almonds and lotus seeds contain higher protein (15%-30%)
Cereals generally contain 6%-10% protein
Potatoes and ordinary vegetables contain 2%-4% protein
2. Is protein easy to digest and absorb
Animal protein is very similar to human protein, but when digesting animal protein, the body needs to consume more energy to break down animal protein into individual amino acid molecules, which are then reconstituted into new proteins for use.
Plant protein belongs to non-high-quality protein and incomplete protein, which is different from human amino acids. The outer layer of plant protein is wrapped by a layer of film, so the digestion process is relatively slow.
In the metabolic process, plant protein will produce more unbalanced amino acids, and its absorption utilization rate is only about 50%
In contrast, the ratio of amino acids in animal protein is relatively balanced, and the digestion and absorption utilization rate can reach about 70%
3. Amino acid ratio
The amino acid structure and ratio of animal protein are similar to that of humans, and the amino acids provided are very close to the eight essential amino acids (except collagen), so it is a better source of protein.
Although the source of plant protein is wide, there is a certain gap between the type of protein and the relative quantity of the human body.
When plant protein is ingested, it is easy to produce the deficiency of essential amino acids such as immunoglobulin, glutamic acid, lysine, etc.
