I believe that anyone who works in fitness is familiar with one word: protein!

Protein is very important for fitness people! But many people don’t have the correct concept of protein intake!

What are the best sources of protein? Is there a difference between soy and milk? How much should you eat every day? The more you eat, the better? When is the best time to take it?

These are the questions that plague most fitness enthusiasts! Let’s take everyone to know about it today!

1. What kind of protein is best? Which is better, soy milk or milk?

How many foods contain protein in nature? But not everything is so good?

In addition to the commonly heard chicken breast, protein nutrients are contained in beef, pork, seafood, tofu, beans and other foods, and even in vegetables. However, the protein content, amino acid ratio, and degree of absorption by the human body are different in each food.

The nutritional value of protein depends on the digestibility and the type and combination of amino acids contained in the protein. Proteins that are easily digested, absorbed and utilized by the human body have high nutritional value

Human protein is composed of 20 kinds of amino acids, 12 of which are called non-essential amino acids that the human body can synthesize through its own biochemical reactions

There are also 8 kinds of amino acids that the human body cannot synthesize and must rely on food to provide them.It is an essential amino acid, and animal protein generally contains 8 essential amino acids for the human body, especially egg products and dairy products

Plant protein contains very little essential amino acids. In particular, it lacks lysine (an essential amino acid), so its amino acid score is lower, and this type of protein is less absorbed and utilized by the body.

If you want a lot of protein, the foods with the highest proportions: lean meat, fish and shrimp, chicken breast, and dairy products will be your choice.
