WHAT ARE REQUIRED FOR CELL GROWTH AND REPAIR?

For cell growth and repair, the body requires a combination of nutrients, energy, and proper physiological conditions. These components ensure cells can divide, regenerate, and function optimally. Here's a breakdown of what is essential:

🔬 1. Macronutrients

Protein

• Amino acids from protein are the building blocks of cells, tissues, enzymes, and hormones.
• Essential for:
• Repairing damaged tissue
• Building new cells (especially during growth, healing, or after injury)
• Good sources: Eggs, fish, chicken, dairy, legumes, tofu

Healthy Fats

• Provide cell membrane components (especially phospholipids and cholesterol).
• Important for brain and nerve cell growth.
• Omega-3 fats help reduce inflammation and support repair.
• Sources: Fatty fish, flaxseeds, chia seeds, nuts

Carbohydrates

• Provide the energy (ATP) needed for cellular processes like mitosis, protein synthesis, and repair mechanisms.
• Sources: Whole grains, fruits, vegetables, legumes

🧪 2. Micronutrients

Vitamins

• Vitamin A: Supports epithelial cell growth and immune response.
• Vitamin C: Crucial for collagen formation, wound healing, and antioxidant protection.
• Vitamin D: Regulates cell growth and immune function.
• B-complex vitamins (especially B2, B6, B9/folate, B12): Help with DNA synthesis, energy production, and red blood cell formation.
• Vitamin E: Protects cell membranes from oxidative stress.

Minerals

• Zinc: Needed for DNA synthesis, cell division, and immune repair.
• Iron: Supports oxygen transport and energy production.
• Magnesium: Involved in over 300 enzymatic processes, including protein synthesis and DNA replication.
• Calcium: Important for cellular signalling and structure.
• Selenium: Acts as an antioxidant in cell repair.

🧫 3. Other Essential Components

Water

• Maintains cellular hydration, nutrient transport, and waste elimination.
• Essential for enzymatic activity and healing.

Oxygen

• Required for cellular respiration and energy (ATP) production.

Antioxidants

• Protect cells from free radical damage during growth and repair.
• Examples: Glutathione, flavonoids, coenzyme Q10

Hormones & Growth Factors

• Insulin, thyroid hormones, and growth hormone stimulate cell growth and protein synthesis.
• Cytokines and growth factors regulate repair and regeneration (e.g., EGF, FGF, VEGF).
