1. Understanding Protein: The Building Block of Life

1.1. What Exactly is Protein?

Protein is a vital macronutrient essential for building and repairing tissues, making enzymes and hormones, and supporting overall health. It’s composed of amino acids, the fundamental building blocks that our bodies use for various functions. Understanding the role of protein helps you make informed dietary choices.

1.2. Why is Protein Important for Your Body?

Protein is crucial for several reasons:

• Muscle Growth and Repair: Protein is essential for building and repairing muscle tissue, especially after exercise.
• Enzyme and Hormone Production: Many enzymes and hormones are proteins, playing critical roles in metabolism and other bodily functions.
• Immune Function: Antibodies that help fight infections are made of protein.
• Energy Source: While not its primary role, protein can be used as an energy source when carbohydrates and fats are lacking.
• Tissue Repair: Protein aids in repairing damaged tissues, promoting faster recovery from injuries.

1.3. How Much Protein Do You Need Daily?

The recommended daily protein intake varies based on factors such as age, sex, activity level, and overall health. Generally, the Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. However, athletes, pregnant women, and older adults may need more. Here’s a quick guide:

Group	Protein Needs (g/kg of body weight)	Example (for a 70kg person)
Sedentary Adults	0.8	56 grams
Endurance Athletes	1.2 – 1.4	84 – 98 grams
Strength Athletes	1.6 – 1.7	112 – 119 grams
Pregnant/Breastfeeding	1.1	77 grams
