What Is Protein?
Protein is a macronutrient made up of amino acids, which are known as the building blocks of the body. These amino acids are responsible for creating and repairing muscles, tissues, enzymes, and hormones.
There are 20 amino acids in total, and nine of them are considered essential. This means the body cannot produce them on its own and they must be obtained through food.
Protein sources are generally divided into two categories:
Animal Protein
- Chicken
- Beef
- Fish
- Eggs
- Dairy products
Plant Protein
- Lentils
- Beans
- Chickpeas
- Tofu
- Nuts and seeds
Health Benefits of Protein
Supports Muscle Growth
Protein is essential for muscle development and recovery. After physical exercise, muscles need protein to repair and grow stronger.
Helps with Weight Loss
High-protein foods increase feelings of fullness and reduce hunger. This can help people eat fewer calories and manage their weight more effectively.
Boosts Metabolism
The body burns more calories digesting protein compared to fats and carbohydrates. This process is called the thermic effect of food.
Strengthens the Immune System
Proteins are important for building antibodies that help the body fight infections and diseases.
Daily Protein Needs
The amount of protein a person needs depends on body weight, age, and activity level.
The general recommendation for adults is:
0.8 grams of protein per kilogram of body weight.
Examples
- Sedentary adults: 0.8 g/kg
- Active individuals: 1.2 – 1.6 g/kg
- Athletes: 1.6 – 2.2 g/kg
For example, a person weighing 70 kg may need between 56 and 150 grams of protein daily depending on physical activity.
