🧬 What Is Protein?

Protein is a macronutrient, like carbohydrates and fats, but it stands out because it’s responsible for building and repairing tissues. Proteins are made up of amino acids, some of which the body can make (non-essential), while others must come from food (essential amino acids).

💪 Why Is Protein Necessary for the Body?

Here are key reasons why protein is vital for your body:

1. Builds and Repairs Muscles

Whether you lift weights or simply go for a walk, your muscles need protein to grow and recover. After any physical activity or injury, protein helps repair muscle fibers.

2. Supports Enzymes and Hormones

Many hormones (like insulin) and enzymes are made of proteins. These regulate essential functions like metabolism, digestion, and mood.

3. Boosts Immunity

Antibodies that protect us from diseases are proteins. Without enough protein, your immune system weakens, making you prone to infections.

4. Promotes Healthy Skin, Hair & Nails

Keratin, collagen, and elastin — all made from proteins — are key for glowing skin, strong nails, and thick hair.

5. Helps in Weight Management

Protein keeps you fuller for longer. It reduces cravings, increases metabolism, and prevents overeating — all crucial for healthy weight loss.

6. Balances Body Fluids

Proteins like albumin and globulin help maintain the body’s fluid balance and prevent swelling (edema).

📏 How Much Protein Do You Need Daily?

The Recommended Dietary Allowance (RDA) for protein is:

• Men: 56 grams/day

• Women: 46 grams/day

• Athletes or Bodybuilders: 1.2–2.0 grams per kg of body weight

Note: Pregnant and lactating women need slightly more protein.
