Protein is a complex of amino acids which form together with a range of blocks. They do their work in the cells of the human body and are in charge of structure and functions and regulate the body’s activity.

Our body needs protein for the growth of our cells and tissues. Therefore, protein should be obtained from a different source to assist both our health and the environment. There are plenty of foods that contain protein, and its consumption will enrich our body with the protein supply.

In food like meat, dairy products, and plant sources (nuts, beans), a large amount of protein can be found, vital for our body and brain. There are many functions that protein can provide to our body, but 4 of them are essential for the proper functioning of a healthy body.

5 High Protein Foods & Vegetables

1. Building and Growth

Protein builds blocks of the body. They are responsible for building, growing, and repairing muscles, vital for the maintenance of tissues, also development and aid of it. Our organs, muscles, hair, and skin are all made up of protein, and that’s why children need more protein for their growth and formulation, as they need new tissues than adults.

2. Boosts Energy

Protein is considered to be a great source of energy. If you use more protein than your body needs for muscle or tissue maintenance, it will be used for energy. If you eat food full of protein, you will feel satisfied and full for a very long time. But there is a massive stock of protein in our body. According to PubMed, if you don’t eat for about 18–48 hours, your body breaks down skeletal muscle so that amino acids (proteins) can provide you with energy.

3. Immune Health

Proteins form antibodies in our body, which are responsible for fighting infections and defense from diseases. Antibodies are proteins in your blood that can protect the human body from bacteria and viruses that can be harmful to the body. When the virus enters the body, already formulated antibodies get reduced and fight against them and creates the immunity system to be protected from other viruses and react faster if they appear again in the future.

4. Hormone Production

Proteins are also involved in the process of formulating some hormones. One of them is insulin, a small protein, a hormone that regulates blood sugar in the blood. Unfortunately, it can’t continuously hold itself, so it’s essential to be very attentive to the blood in your body. If there’s a problem with insulin, look into the insulin index to control food consumption and the necessity of using vitamins or other nutrients.


Protein has a significant role in your body, and it implements many vital functions and activities. It keeps the immune system healthy, formulates solid muscles and tissues, helps the metabolic processes, and protects from viruses by creating strong immunity. So it will be perfect for your health to consume healthy food, keep physical activity and be attentive not to catch harmful diseases.
