30-day plan · For Gut microbiome support / post-antibiotic recovery / IBS
30-Day Gut Healing Meal Plan
Gut healing is slow work. The lining of your small intestine replaces itself every 5-7 days; full microbiome shifts take 4-6 weeks of consistent input. The plan below pulls four levers: fermented foods (introduces beneficial bacteria), prebiotic fiber (feeds the existing microbiome), bone broth (provides glutamine for intestinal cells), and gentle digestive bitters (ginger, fennel, peppermint).
Foods to emphasize
- Fermented foods daily — sauerkraut, kimchi, miso, kefir, raw yogurt
- Bone broth 1 cup daily (homemade or quality store-bought)
- Prebiotic fiber — onion, garlic, leek, asparagus, artichoke, banana
- Cooked-and-cooled rice/potato (resistant starch)
- Ginger fresh 1-2 tsp daily
- Bitters — arugula, dandelion, watercress
- Plant variety — aim for 30 different plant foods per week
Foods to avoid
- Antibiotics-laced meat (choose organic/grass-fed/wild)
- Artificial sweeteners (sucralose, aspartame disrupt microbiome)
- High-fructose corn syrup
- Excess alcohol (irritates intestinal lining)
- NSAIDs daily (damages gut lining over time — talk to clinician about alternatives)
Safety
IBS triggers vary by person. Some experience worse symptoms initially as the microbiome rebalances ("herx reaction"). If symptoms severely worsen, reduce fermented food portions and reintroduce slowly. Stop and consult clinician if blood appears in stool or severe pain develops.
Supplementation
No supplements required for the plan. Optional: a high-quality probiotic for 2-4 weeks if recovering from antibiotics. L-glutamine 5g daily for 2 weeks if symptoms are severe. Always check with clinician first.
Week 1: Introduce fermented foods
Days 1–7Start with small portions (1-2 tablespoons sauerkraut/kimchi daily). Build to 1-2 servings daily by end of week. Start daily bone broth.
Milestone: By day 7: digestion noticeably more regular. Bloating reduced. Mild improvement in skin clarity (gut-skin axis).

Week 1 shopping list
- • Live sauerkraut · Live kimchi · Plain Greek yogurt · Kefir · Miso paste
- • Bones for broth (chicken backs + carcasses + a few knuckle bones)
- • Salmon · Mackerel · Sardines · Tempeh · Chicken whole · Lentils

Week 2: Plant variety drive
Days 8–14Aim for 30 different plant foods this week. Vary your vegetables daily. Variety drives microbiome diversity which independently predicts gut health.
Milestone: By day 14: stool regularity improved. Less bloating after meals. Energy more stable. Less brain fog.
| Day | Breakfast | Lunch | Dinner | Snack |
|---|---|---|---|---|
| 8 | Smoothie: kale + berries + banana + chia + Greek yogurt | Bone broth + roasted root vegetables | fenugreek-cinnamon-blood-sugar-curry (adds new plant variety) | Apple + walnut butter |
| 9 | Oatmeal with apple + cinnamon + flax | Lentil-chickpea-spinach soup | Roast chicken + leek + brussels sprouts | Carrots + hummus |
| 10 | Kefir smoothie | Big salad with arugula + watercress + sardines | Salmon + asparagus + sweet potato | Berries + pumpkin seeds |
| 11 | Eggs with onion + spinach + mushrooms | Bone broth + miso + brown rice | Indian lentil curry + spinach | Kefir + berries |
| 12 | Yogurt parfait with cinnamon + walnuts | Veggie wrap with hummus + sauerkraut | Mackerel + roasted root vegetables | Apple |
| 13 | Steel-cut oats with banana + cinnamon | Soup leftovers | Roast chicken + onion + leek + carrot | Berries |
| 14 | Vegetable omelet (use new vegetables you have not had) | Big variety salad | Batch cook for week 3 | Almonds |
Week 2 shopping list
- • Brussels sprouts · Sweet potato · Watercress · Mushrooms · Pumpkin seeds · Refresh produce
Week 3: Resistant starch + cooked-and-cooled foods
Days 15–21Add cooked-then-cooled rice/potato. Resistant starch resists digestion in small intestine and feeds beneficial bacteria in the colon. Add 1 portion daily.
Milestone: By day 21: digestive comfort sustained. Most plan-followers report meaningful reduction in bloating, gas, or post-meal discomfort.
| Day | Breakfast | Lunch | Dinner | Snack |
|---|---|---|---|---|
| 15 | Cold rice salad with vegetables + olive oil + lemon (resistant starch) | Bone broth + roasted vegetables | fenugreek-cinnamon-blood-sugar-curry over hot rice | Apple + walnut butter |

| 17 | Kefir smoothie | Buddha bowl with cold rice + kimchi + chickpeas | Salmon + leeks + asparagus | Berries + walnuts |
| 18 | Eggs with onion + mushrooms + spinach | Bone broth with miso + greens | Tempeh stir-fry with bok choy + cold rice (resistant starch) | Apple |
| 19 | Oatmeal with banana + cinnamon (cooked-and-cooled overnight oats also work) | Big salad with sardines + arugula | Roast chicken with rosemary + roasted vegetables | Almonds |
| 20 | Smoothie with kale + banana + flax + Greek yogurt | Soup with cold-cooked rice (resistant starch) | Mackerel + roasted brussels + carrots | Berries |
| 21 | Vegetable scramble | Variety bowl | Batch cook for week 4 | Kefir + berries |
Week 3 shopping list

Week 4: Lifestyle integration
Days 22–28Lock in the fermented-food-daily habit and bone-broth-daily habit. Identify which 3-4 meals fit your life best and rotate them as a new baseline.
Milestone: By day 30: most plan-followers report sustained improvement in digestive comfort. Microbiome diversity (if tested via stool sample like Viome or Biomesight) shows measurable shift toward beneficial species.
