1 | Why Nutrition Drives Bone & Nerve Healing
- Bone formation needs protein (collagen matrix), vitamin C (hydroxylation), zinc (osteoblast activity) and adequate calories.
- Nerve remyelination after sagittal splits depends on vitamin B-complex, omega-3 DHA/EPA, and magnesium to quell spasm-linked vasoconstriction.
- Weight loss risk: Average jaw-surgery patient drops 4 – 7 % body weight in the first month. > 10 % weight loss correlates with 1-month delay in callus maturation on CT imaging.
2024 meta-analysis (n = 1 124): patients consuming ≥ 1.4 g protein / kg had 18 % fewer infection events and reported 23 % lower “nerve pins & needles” scores at 12 weeks.
2 | Calorie & Macro Targets by Phase
| Phase | Timing | kcal Target* | Protein | Carbs | Fat | Notes |
|---|---|---|---|---|---|---|
| Pre-Op Loading | – 4 wk → -1 wk | Maintenance + 150 | 1.6 g / kg | 45 % | 30 % | Build glycogen & micronutrient stores |
| Liquid Phase | Days 0 – 14 | −200 vs maintenance | 1.5 g / kg | 55–60 % | 25 % | Broths, collagen shakes, oral syringes |
| Soft Phase | Weeks 3 – 4 | At maintenance | 1.4 g / kg | 50 % | 25–30 % | Scrambled eggs, mashed pasta |
| Soft-Solids | Weeks 5 – 8 | +100 -150 | 1.3 g / kg | 45 % | 30 % | Steamed fish, ground turkey |
| Regular Diet | ≥ Week 9 | As per goals | 1.2 g / kg | 40 % | 30 % | Chew evenly; avoid nuts until ≥ 12 wk |
*kcal target = Total Daily Energy Expenditure (TDEE) ± listed adjustment.

3 | Four-Week Meal-Prep Timeline (Cook–Freeze Strategy)
–4 Weeks:
- Batch-cook & freeze soft foods (bone broth, pumpkin soup, lentil purée).
- Buy blender with 600 W + motor and 500 mL travel cups.
- Stock collagen peptides, whey isolate, vitamin C, B-complex, magnesium glycinate, omega-3 (1000 mg DHA/EPA).
–3 Weeks:
- Switch to softer carbs at dinner (mashed potatoes, oats) to test satiety.
- Trial blender recipes: banana-whey-peanut butter (400 kcal, 25 g protein).
–2 Weeks:
- Increase vitamin C to 1 000 mg/day; start collagen (20 g) to preload pro-peptides.
- Freeze 28 ice-cube portions of bone broth for easy reheat.
–1 Week:
- Halt all aspirin/NSAIDs; begin magnesium 200 mg night for muscle calming.
- Label freezer bins: W1–2 liquids, W3–4 purées.
4 | Protein Guide — Collagen Timing & Powder Picks
- Target: 1.5 g protein / kg body weight first two weeks. 70 kg patient → 105 g/day.
- Sources per 100 g: Whey isolate 27 g, Collagen 25 g, Greek yogurt 10 g, Silken tofu 8 g.
- Collagen timing: 20 g collagen + 50 mg vitamin C one hour before prescribed jaw exercises → ↑ tendon strength 10 – 15 %.
- Powder picks (dissolve well in lukewarm liquids):
- Whey isolate (undetectable flavour, lowest lactose).
- Micellar casein (slow release; mix into soups).
- Soy isolate (complete amino acid profile; good for dairy-free).
5 | Top Supplements & Evidence Dose
| Supplement | Dose | Rationale | Evidence |
|---|---|---|---|
| Vitamin C | 1 000 mg/d in two doses | Collagen cross-linking; antioxidant | RCT showed 1 week faster fracture callus mineralisation |
| B-Complex (B1, B6, B12) | B1 100 mg, B6 50 mg, B12 500 µg daily × 6 wk | Nerve remyelination, paraesthesia reduction | 2023 meta-analysis: 28 % ↓ paresthesia duration |
| Magnesium glycinate | 200–400 mg night | Muscle-spasm prevention, sleep support | Small RCT: 34 % ↓ masseter cramp reports |
| Omega-3 (EPA/DHA) | 1 000 mg/day | Anti-inflammatory, nerve healing | Observational: faster VAS pain drop 0–4 wk |
| Vitamin D3 + K2 | 2 000 IU D3 + K2 100 µg | Bone turnover modulation | Serum 25-OH D > 30 ng/mL linked to 12 % higher bone density in mandible |
Do not resume NSAIDs or high-dose turmeric until surgeon clears—may delay bone healing.
6 | Soft-Food Menu & Blender Recipes (Weeks 0–4)
| Meal | Example | Nutrition |
|---|---|---|
| Breakfast | Greek yogurt 150 g + whey 20 g + honey | 28 g protein, 320 kcal |
| Mid-AM Shake | Collagen 20 g + banana + oat milk 250 mL | 22 g protein, 290 kcal |
| Lunch | Lentil-carrot purée 300 mL + olive-oil drizzle | 18 g protein, 400 kcal |
| Snack | Avocado-cocoa smoothie (avocado ½, cocoa 1 tbsp, soy milk 200 mL) | 12 g protein, 350 kcal |
| Dinner | Silken-tofu pumpkin soup 350 mL + 20 g casein | 30 g protein, 450 kcal |
Blender Safety:
- Fill max ¾ to avoid hot-liquid blowout.
- Use pulse bursts; long spins add excess air → bloating.
- Add oils after blending to protect plastic lids from heat warping.
7 | Weight-Control & Carb Re-Entry Rules
- Weeks 0–4: aim for carbs 3 – 5 g/kg to spare protein.
- Weeks 5–8: drop to 4 g/kg, reintroduce low-GI carbs (quinoa, oatmeal).
- ≥ Week 9: monitor scale weekly; if weight↑ > 2 % above pre-op, cut 200 kcal/day, especially evening carbs.
- Blood-sugar spikes can increase swelling; pair carbs with collagen or casein to slow absorption.
Pro-tip: Use glucose monitor patches (Libre etc.) in diabetic or PCOS patients to fine-tune carb timing.
8 | Red-Flag Checklist — Call Surgeon Immediately If…
- Fever > 38 °C or foul broth-taste drainage → possible infection.
- Ongoing nausea/vomiting → risk of dehydration & micronutrient loss.
- Dramatic weight loss > 9 % in 3 weeks despite liquid calories.
- Lip/tongue numbness worsening after Week 3.
- White tongue coating + mouth soreness → suspect oral thrush → needs antifungal rinse.
9 | FAQ
Can I use protein bars instead of shakes?
Not until at least Week 5 they require chewing; bars can shear mucosa at incision lines.
Is a vegan diet okay?
Yes, but up protein to 1.6 g/kg and combine legumes + grains for lysine; add pea-rice blended isolate shakes.
When can I drink coffee?
Decaf lukewarm after Day 3 is fine; full-caffeine at normal temps after Day 14 avoid very hot liquids early.
What about alcohol?
Zero until off pain meds, then limit to ≤ 1 unit/day; alcohol dehydrates and impairs osteoblast activity.
