Summary
On episode 122 of 40+ Fitness, Coach Allan sits down with Christine Bailey, a qualified nutritionist, food and health consultant, chef, and cookery teacher who is one of the most respected nutrition experts in the digestion-focused sector of functional medicine, to discuss her book The Gut Health Diet Plan.
Christine’s argument: irritable bowel symptoms are not a diagnosis in themselves, they are a signal of an underlying imbalance, usually in the gut’s immune system, and real relief comes from finding your specific trigger rather than just managing symptoms.
The conversation walks through her five R framework for healing the gut (Remove, Replace, Repopulate, Repair, Rebalance), why nutrient absorption matters as much as food choice, and where foods like eggs and fermented staples fit into the plan.

Key Takeaways
- IBS is a set of symptoms, not a disease. It affects roughly 10 to 20 percent of the population, about 60 million people in America, and includes bloating, abdominal pain or cramping, and alternating diarrhea and constipation.
- The causes behind those symptoms vary widely. Food immune reactions, missing enzymes like lactase, and overgrowth of bacteria, yeast, or parasites in the gut can all be behind it, along with stress and certain medications.
- You are what you absorb, not just what you eat. Stomach acid and digestive enzyme production naturally decline with age, and eating on the go without chewing properly compounds the problem, so good food choices alone are not enough.
- Simple habits improve digestion before you change your diet. Chewing thoroughly, sipping lemon water or apple cider vinegar before a meal, and eating bitter greens like chicory, rocket, or watercress all help trigger the enzymes needed to break food down.
- The program runs on five R’s. Remove your triggers, Replace digestive enzymes and support, Repopulate the microbiome with fermented foods like kefir, kombucha, sauerkraut, kimchi, miso, and tempeh, Repair the gut lining, and Rebalance stress and mindset.
- About 70 percent of the immune system sits in the gut. Rebuilding the microbiome has effects well beyond digestion; Christine’s own son saw a real change in his skin health after adding more fermented foods to his diet.
- A damaged gut lining, or leaky gut, is linked to bigger problems. When intestinal permeability lets undigested proteins into the bloodstream, it is associated with long-term inflammatory and autoimmune conditions, which is why repairing the gut lining matters.
- The removal phase is flexible, not fixed. The book outlines one week of removal, but some people need a month or longer, and anyone with celiac disease needs to avoid gluten for life, not just during the program.
- Eggs are more nutrient-dense than most elimination diets treat them. Egg yolks rarely cause issues even when whites do, since lectins concentrate in the white, and vegetarians in particular need eggs for protein while healing the gut.
“We are what we absorb and assimilate.”
