Gut health

Leaky gut is not an isolated intestinal pathology but a manifestation of a systemic energy deficiency and hypothyroidism, which slows peristalsis and allows bacterial overgrowth. 3 Peat argued that the root cause of increased intestinal permeability is a sluggish metabolic rate, which reduces the flushing action of digestive secretions, causing the small intestine to become a stagnant environment where bacteria can thrive. 2 This condition, often diagnosed as SIBO, is secondary to the thyroid’s failure to maintain adequate digestive speed and glycogen stores. 2 Roddy has written that the gut’s contribution to disease is secondary to an energy deficiency, framing the entire "evolutionary" model of intestinal health as misguided because it ignores the central role of stress hormones. 3

At the cellular level, Peat described leakiness as a structural breakdown where the cell substance itself becomes disorganized, taking on water and allowing proteins and environmental junk to pass through. 4 This process is driven by endotoxin, which is always present in the intestine, but is also triggered by other stressors including radiation, heavy metals, estrogenic substances, and polyunsaturated fatty acids. 4 These agents cause a saponification-like effect, loosening the cell’s lipid structures so that the barrier fails not just in the gut, but potentially in capillaries and other tissues, leading to a pre-cancerous state where characteristic proteins leak from stressed organs. 4 Dinkov has extended this by noting that serotonin itself is a necessary and sufficient condition to trigger inflammatory bowel disease by increasing gut permeability, independent of endotoxin. 10

The repair of the intestinal lining depends on a full spectrum of nutrients, with magnesium and vitamin A being the most critical for cell replacement. 3 Peat recommended liver, eggs, milk, and orange juice to initiate repair, but cautioned that consuming concentrated protein like eggs without adequate carbohydrate will drop blood sugar, activate mast cells, and provoke allergic inflammation. 2 He identified aspirin as a potent defense against a leaky intestine because it prevents the actions of endotoxin, contrary to claims that it causes intestinal damage. 8 Dinkov has argued that most bacteria sold as probiotics are capable of producing endotoxin and are therefore harmful, challenging the notion that the gut microbiome can be neatly divided into good and bad strains. 7

The systemic nature of the condition means that a leaky gut is often accompanied by a leaky liver, muscles, and heart, with the immune system reacting to the resulting debris in a way that is frequently mislabeled as autoimmunity. 9 Peat stressed that hypothyroidism is the common denominator causing poor absorption and retention of magnesium, sodium, and copper, which further compromises the synthesis of proteins needed to maintain the barrier. 8 The therapeutic goal is to speed up a sluggish digestive tract so that the streaming fluid from the stomach, pancreas, and liver washes the small intestine clean, making it inhospitable to bacteria. 2 Roddy notes that intestinal disinfectants and a focus on energy production are often the most effective interventions for restoring digestive function and resolving the devastating quality-of-life issues associated with chronic gut problems. 5
