The 6 Main Functions of Protein in Your Body

Published On:

Many kinds of research created the link between diet and health. We now know that protein is an essential nutrient for good health, and the body needs a variety of protein foods to get the protein it needs. 

The importance of protein in the diet is becoming more and more recognized as a key to good health and well-being. Protein is crucial for the maintenance of muscle mass and the building of new tissue and cells. It’s also a key component of many of the body’s systems and is required to function many of its organs.

Let’s go through all the functions of proteins and how it is the star of our diets:

What are the Advantages of Protein to Your Body?

Here are some advantages that protein offers your body!

  • The effect of a high-protein diet on your body composition is one of the most important advantages. Research has shown that high-protein diets are critical for maintaining muscle mass as you lose weight, and they also have a significant impact on your body fat composition.
  • In one study, researchers assigned obese adults to a high-protein diet or a conventional diet and measured their body fat composition before and after eight weeks. The high-protein group experienced significantly more significant increases in lean body mass and decreases in body fat than the conventional diet group.
  • Amino acids, which are the building blocks of protein, are used to make proteins. The human body can make some amino acids, but it needs a variety of amino acids from different foods to produce the protein it needs. 
  • The body can’t manufacture its amino acids, so it relies on the diet to provide the amino acids it needs. This is why it’s so vital to eat a well-balanced diet that contains a range of protein-rich meals.

What are the 6 Primary Roles of Protein in the Human Body?

Protein in the Human Body

Proteins are required for various bodily activities. Some of the main roles of protein in the body include: 

1. Building and maintaining muscle mass.

This is particularly important as you lose weight, as it helps you maintain lean body composition and keep muscle mass on your body. Proteins are the most effective technique for feeding and maintaining muscle mass. They’re also involved in muscle tissue healing and maintenance. In addition, the amino acids in protein are used to build new muscle tissue.

2. Aiding in the absorption of nutrients.

The body uses Amino acids in protein to make other, more important protein compounds, including hormones, enzymes, and other proteins. This helps to aid in the absorption of important nutrients from your diet. 

For example, the amino acid arginine is used to make the amino acid citrulline, used to make urea. As a by-product of protein metabolism, this molecule is eliminated from the body. Urea is important for the function of the kidneys and is necessary for the body’s normal functioning.

3. Contributing to the function of many of the body’s systems.

Proteins are needed to function some of the body’s major organs, including the liver, the kidneys, the pancreas, the heart, and the brain. They are also needed to construct and maintain the body’s systems, including the immune system, blood clotting, blood sugar regulation, and nervous system function. 

It means that a diet that is high in saturated fat and cholesterol and too low in protein may increase the risk of heart disease, stroke, some cancers, and osteoporosis, among other conditions. 

4. Providing energy for the body’s cells and tissues. 

Proteins are the most efficient source of energy in the body. They are used to provide the body’s energy to function and to build and repair tissue. Protein is broken down into its component amino acids by the body and used to synthesize other, more critical protein compounds, including hormones, enzymes, and other proteins. This helps to provide the body with energy.

5. Being a source of crucial amino acids.

Amino acids in protein are used by the body to build new tissue and cells, which is why having a varied diet is so important for good health. In addition, the amino acids in protein are used to synthesize other proteins, which is why eating a variety of protein-rich foods is so important for the body’s health. 

This is particularly important for adults as the body no longer manufactures its own protein, so it needs a variety of protein-rich foods to get the amino acids it needs. This is one of the reasons a balanced diet that includes a variety of protein-rich foods is so important for adults.

6. Normal cellular function necessitates the creation of hormones, enzymes, and other proteins.

They contribute to the production of hormones, such as insulin and testosterone, which are important for many of the body’s functions. Researchers are also exploring the potential of proteins to play a role in preventing and treating specific conditions, such as cardiovascular disease, osteoporosis, and some cancers. Proteins are also thought to have a role in preventing age-related conditions, such as osteoporosis. 

Protein in Large Quantities?

Protein in Large Quantities

Protein being an essential element for good health, can have a positive impact when taken in small amounts, but it is when taken in large amounts that it becomes a problem. This is because the protein in large amounts is complex for the body to break down and use as an energy source. 

This is particularly the case for the protein that is “complete,” which is the protein that provides all the essential amino acids the body needs in the proper proportions. This means that when taken in large amounts, protein becomes a “complete protein” and no longer has any nutritional value to the body. 

In reality, the majority of Western diets include far more protein than is required for optimum health. In actuality, most Western diets include substantially more protein than is necessary for good health. So protein intake in large quantities has proven inadequate for the human body. 

For example, an athlete who works out intensely and consumes large amounts of protein for its own sake is probably doing himself a disservice and may be setting himself up for a host of health issues in the future.

Protein Intake Recommended by Doctors

Protein Intake Recommended by Doctors

A diet that is too high in protein increases the risk of kidney disease, dehydration, and some gastrointestinal disorders. Protein should be consumed in amounts of 56 grams per day for men and 46 grams per day for women.

Still, the recommended amount is based on various factors, including age, gender, activity level, weight, and health status. These recommendations are designed to ensure that everyone gets enough protein on a daily basis but does not contain too much-saturated fat or cholesterol. 

The RDA for protein is also a “suggested average,” which means that everyone needs to manage their protein intake to some extent to meet their needs, based on their unique body composition, health status, and activity levels.


1. What happens if you don’t get enough protein?

Insufficient protein can cause you to lose muscle mass over time, reducing your strength, making it more challenging to maintain your balance, and slowing your metabolism. It can also cause anemia, which causes you to feel weary because your cells aren’t getting enough oxygen.


2. What happens when protein is converted into muscle?

Enzymes inside the stomach and small intestine break down protein to produce peptides after your plate is transparent. Your body uses these amino acid chains as bricks and mortar to construct muscle fibers. The more you practice, the more you’ll need.


3. On a daily basis, how much protein do I need?

For an average sedentary adult, the recommended dietary need to prevent deficiency is 0.8 g per kg of body weight. A 75 kg (165 pounds) individual, for example, should take 60 g of protein per day.


4. What fruits are high in protein?

Protein-rich foods include guavas, avocados, apricots, kiwifruit, blackberries, oranges, bananas, cantaloupe, raspberries, and peaches. Because a cup is simpler to compare, the list below is organized by serving per cup


5. What illnesses can you get if you don’t eat enough protein?

Too little protein in the diet can arise long-term changes in body composition, such as muscle atrophy. The most severe type of protein deficiency is Kwashiorkor. It is more frequent among children in underdeveloped nations, where starvation and unbalanced nutrition are prevalent.


In moderation, protein can help build and repair your body, helping you achieve your fitness goals. The evidence is clear-cut that diets high in protein are bad for your health. Protein is essential for good health, but it can also be a problem when consumed in large quantities and then becomes a “complete protein” and no longer has any nutritional value to the body. 

The key is to ensure that you are getting a variety of protein sources throughout the day and focus on eating various protein-dense foods, such as fish, pulses, meat, and dairy. So, be wise and moderate and stick to what you need, not more!
