What are proteins and why are they so important for your body?

Proteins are one of the most essential nutrients for life. They are present in every cell of our body and are responsible for vital functions that go far beyond muscle growth. But what exactly are proteins, and what is protein used for in our body?

In this article, we explain it clearly and simply, and show you how you can ensure you consume the right amount with the help of functional supplements such as Fit Blend™ from Baïa Food.

What are proteins?

Proteins are complex organic molecules made up of chains of amino acids that act as the body’s building blocks. There are 20 different amino acids, 9 of which are essential, meaning the body cannot produce them on its own and they must be obtained through the diet.

When we consume proteins, our body breaks them down into amino acids, which are then used to build and repair tissues, produce hormones, enzymes, neurotransmitters, and much more.

Structure and key functions

1. Tissue structure

Proteins are part of muscles, skin, nails, and hair. Keratin, for example, is a structural protein in hair and nails.

2. Regulation of bodily processes

Proteins regulate multiple processes through the production of enzymes (for digestion, for example) and hormones (such as insulin).

3. Body defense

They are vital for the immune system. The antibodies that protect us from viruses and bacteria are specialized proteins.

4. Nutrient transport

Hemoglobin, which carries oxygen in the blood, is also a protein.

What is protein used for in your daily life?

Getting enough protein is not just for athletes. This nutrient:

Helps maintain and build muscle mass.
Promotes satiety, which can help with appetite control and fat loss.
Supports muscle recovery after exercise.
Is key to maintaining metabolic health, especially as we age.

How can you ensure an adequate protein intake?

You can obtain protein through foods such as:

Animal sources: meat, fish, eggs, dairy products.
Plant-based origin: legumes, seeds, nuts, whole grains.

However, in certain contexts—such as a low-calorie diet, an active lifestyle, or older age—it may be useful to complement the diet with a functional supplement such as Fit Blend™.
