Protein: The Ultimate Guide πͺβ¨
What is Protein?
A βBodybuilding Nutrientβ essential for growth, repair & maintenance.
Made up of amino acids; contains nitrogen (unique from carbs & fats).
Found in muscles (50%), bones (20%), skin (10%), and other tissues.
Key Functions
1οΈβ£ Bone Health
Collagen forms the framework for bones, teeth, tendons, & ligaments.
Stores calcium & phosphorus.
2οΈβ£ Growth & Repair
Nitrogen supports cellular growth & tissue repair.
3οΈβ£ Essential Compounds
Enzymes (pepsin), hormones (insulin), and blood-clotting proteins (fibrin).
4οΈβ£ Muscle Function
Actin & myosin enable muscle contraction.
5οΈβ£ Immunity
Antibodies (immunoglobulins) fight infections.
6οΈβ£ Nutrient Transport
Lipoproteins move fats; retinol-binding protein carries vitamin A.
Amino Acids: Proteinβs Building Blocks
Essential: From diet (e.g., leucine, lysine).
Non-Essential: Made by the body (e.g., glycine, alanine).
Conditionally Essential: Needed during stress (e.g., glutamine).
Special Roles
Energy (BCAAs), immunity (glutamine), growth hormones (arginine).
Liver detox (cysteine) & neurotransmitter production (tyrosine).
Protein Sources
First-Class (High BV): Whey, eggs, chicken, fish, milk, paneer.
Second-Class: Pulses, beans, legumes, cereals, nuts.
Protein Needs (Based on Activity)
Sedentary: 0.8β1 g/kg body weight.
Beginner: 1β1.5 g/kg.
Advanced: 2β3 g/kg.
Absorption Speeds
Fast: Whey, egg whites.
Moderate: Whole eggs, whey with milk.
Slow: Paneer, yogurt, chicken.
Quick Tips
Aim for a Positive Nitrogen Balance to support muscle growth.
Protein digestion begins in the stomach with enzymes like pepsin.
Absorbed in the small intestine and distributed via the bloodstream.
Fuel your body with high-quality protein for optimal health & performance! π₯
