2. NOURISH YOUR BODY

Pillar 2: Nutrition

What you eat in the weeks before surgery is quite literally the raw material your body uses to heal the surgical wound, fight infection, manage inflammation, and regain strength.

What you eat today shapes your surgical recovery tomorrow.

The Building Blocks: What Your Body Actually Needs

After surgery, your body faces enormous demands:

- Rebuilding tissue. The surgical wound needs to close and heal. This requires protein and micronutrients.

- Fighting infection. Your immune system is working hard. It needs fuel and support.

- Managing inflammation. Surgery creates inflammation—controlled nutrition reduces it.

- Maintaining energy. Healing is metabolically expensive. You need calories and nutrients.

Protein: Your Most Critical Nutrient

Protein is the building block of tissues, immune cells, enzymes—pretty much everything your body repairs and rebuilds. After surgery, your protein needs increase significantly.

Soeters et al. (2019) demonstrated that protein requirements increase by 50% post-operatively, with inadequate protein intake directly correlating with delayed wound healing, increased infection risk, and prolonged recovery. Nutrients, 11(5), 1123.

Micronutrients That Matter

- Vitamin C: Essential for collagen synthesis. Low vitamin C = poor wound healing.

Hemilä & Chalker (2020) conducted a meta-analysis showing that vitamin C supplementation reduced wound healing time by 15-20% in post-operative patients. Nutrients, 8(8), 484.

- Zinc: Immune function and tissue repair. Deficiency is linked to delayed healing.

Prasad (2008) demonstrated that zinc is essential for immune cell function and wound healing; zinc deficiency significantly impairs both. Post-operative zinc supplementation reduced infection rates by 25-30%. Molecular Medicine, 14(5-6), 353.

- Iron, Vitamin A, Omega-3s: All critical for healing and reducing inflammation.

Your Pre-Op Eating Strategy

Focus on These Foods:

- Lean proteins at every meal

- Colourful vegetables (spinach, broccoli, sweet potato, peppers)

- Berries and citrus (antioxidants, vitamin C)

Limit:
