Let's talk about the purposes of protein, how much you should be eating, and what foods will help you reach your protein goals!
Purposes of proteins:
1. Fabric construction and repair
- Muscle growth and repair: Protein is vital for muscle repair and growth, so it's especially important for athletes and those who exercise regularly.
- Wound healing: Protein helps repair tissue and is crucial for healing cuts, scrapes and other injuries.
2. Production of enzymes
- Catalytic reactions: Proteins function as enzymes that catalyze and speed up biochemical reactions needed for digestion, energy production, blood clotting and many other processes.
3. Hormonal regulation
- Hormone synthesis: Many hormones, such as insulin and glucagon, are proteins that regulate various physiological processes, including metabolism, blood sugar levels, and growth.
4. Immune function
- Antibody formation: Proteins are essential for the immune system as they help form antibodies that fight infection and disease.
- Immune response: Proteins also play a role in the functioning of other immune cells.
5. Transport and storage
- Transport proteins: Proteins such as hemoglobin carry oxygen in the blood and other transport proteins move nutrients and molecules across cell membranes.
- Storage proteins: Some proteins, such as ferritin, store nutrients and minerals in the body.
6. Structural support
- Cell structure: Proteins provide structural support to cells and tissues. For example, collagen, a structural protein, gives strength and elasticity to skin, tendons and ligaments.
- Keratin: Another structural protein, keratin, is essential for the structure of hair, nails and the outer layer of the skin.
7. Energy source
- Energy production: Although carbohydrates and fats are the primary sources of energy, protein can also be broken down for energy when needed, especially during prolonged exercise or starvation.
8. Fluid balance
- Maintain osmotic balance: Blood proteins, such as albumin, help maintain fluid balance by preventing excess fluid from escaping from the blood vessels into the tissues.
9. pH balance
- Buffer systems: Proteins help maintain the body's acid-base (pH) balance by acting as buffers that neutralize acids and bases.
10. Transport and storage of nutrients
- Transport of nutrients: Certain proteins bind to and transport nutrients and minerals through the bloodstream to various parts of the body.
- Nutrient storage: Proteins can also store essential nutrients for later use.
As a general rule, you should consume at least 100g of protein per day to keep your body functioning optimally. This amount increases if you want to build muscle mass (which we do, duh!). To build muscle mass, you'll want to consume 0.8-2.2 grams per pound of body weight. I usually have clients eat 0.8-1g (so a 150lb person would consume 120-150g).
You might be thinking, “How the hell am I supposed to eat so much protein?!” Below is a 3 day sample of 150 grams of protein. 🙂 And below is a list of high protein foods!
