Study Notes

Digestion

  • Tongue: Thoughts and emotions about food significantly affect digestion. Savouring delicious foods is beneficial.

  • Salivary Glands: Saliva lubricates the mouth and releases amylase (carbohydrate-digesting enzyme) and lingual lipase (fat-digesting enzyme). Chewing food thoroughly before swallowing improves digestion.

  • Stomach: Frequent overeating disrupts satiety signals. Eating slowly allows the body to respond to hunger/fullness cues (leptin takes ~20 minutes to signal the brain). Different foods digest at varying speeds (e.g., fats/proteins/fiber slowest; simple carbs fastest). A meaty meal can take 6+ hours to digest, while fibrous foods take longer.

  • Small Intestine: 90% of nutrient digestion and absorption occurs here, starting in the duodenum. The jejunum absorbs glucose & vitamins; the ileum absorbs amino acids, fats, and fat-soluble vitamins. The migrating motor complex (MMC) cleanses the small intestine when empty. Constant snacking disrupts this process.

  • Liver & Gallbladder: The liver produces bile, stored and recycled in the gallbladder, for fat digestion in the small intestine.

  • Pancreas: The pancreas secretes enzymes (amylase, lipase, proteases) to further break down proteins, fats, and carbs; sodium bicarbonate neutralizes stomach acid.

  • Large Intestine: The large intestine houses a vast microbiome that digests fiber and sugar, producing short-chain fatty acids, vitamin K, and certain B vitamins. It also extracts water and moves waste. Transit time (12-42 hours) varies.

  • Constipation: Conditions like IBS, SIBO, dehydration, enzyme/magnesium deficiencies, gallbladder removal, stress, and allergies can cause constipation. Remedies include fiber-rich foods, psyllium husk, water intake, exercise, stress reduction, probiotics, and altering toilet position.

  • Diarrhoea: The body's speedy response to perceived threats (too much fiber, food allergies, anxiety) results in a rapid transit time.

Microbiota

  • Stability: Microbiota stabilizes by age 2-5, with a unique mix of bacteria. Changes during puberty, pregnancy, and menopause affect energy levels and mood.

  • Food and Microbiota: Fiber-rich complex carbs feed good gut bacteria, creating vitamins, hormones, and nutrients.

  • Microbiota's Influence: Influences digestion, metabolism, weight regulation, hunger hormones, food choices, blood sugar, immune system, sleep, neurotransmitters, mental health, thyroid, inflammation, and various diseases.

  • Factors Affecting Microbiota: Antibiotics, medications, environmental toxins, lifestyle, stress, processed foods, antibiotics in livestock, travel, and lack of sleep disrupt microbiota.

Leaky Gut

  • Compromised Gut Lining: Holes can form in the small intestine, allowing undigested food, bacteria, and toxins to enter the bloodstream, which can be repaired by diet.

Gut and Immune System

  • Gut-Immune Connection: 80% of the immune system resides within the gut. A balanced ratio of good (85%) to bad bacteria supports wellbeing. Microbiota teaches the immune system to tell the difference between good and harmful pathogens.

Inflammation

  • Body's Response: The body’s method of healing and restoration to the injured part, characterized by heat, pain, redness, and swelling.

  • Chronic Inflammation: Several factors contribute to chronic inflammation (e.g., processed foods, refined sugars, omega-6 oils, stress, lack of sleep). Anti-inflammatory diets are ideal. Natural anti-inflammatory options include turmeric, ginger, garlic, and various fruits and vegetables.

Gut-Brain Axis (GBA)

  • Communication Highway: The vagus nerve connects the gut and brain, transmitting signals about stress/anxiety. Maintaining a balance of good gut bacteria influences mood, brain activity, and various cognitive functions.

Neurotransmitters (NT)

  • Gut Production: The gut produces the majority of serotonin (90%) and dopamine (50%).

  • Optimal Production: Many NTs depend on adequate intake of all macronutrients and optimal levels of micronutrients (especially B vitamins).

  • Negative Influences: Some foods (e.g., coffee, alcohol, low vitamins) interfere with NT production.

Serotonin

  • Mood Regulation: The "feel-good" hormone, regulating mood, emotions, behaviour, digestion, appetite, sleep, memory and sexual desire.

  • Synthesis: Produced from tryptophan; requires adequate B vitamins (especially B6 and B12) for synthesis. Complex carbs raise serotonin levels more quickly.

Dopamine

  • Motivation Hormone: Regulates focus, concentration, pleasure, feeling of bliss and affects muscle control, attention and learning, memory and mood.

  • Balance is Key: Imbalance can cause lethargy or reduced libido. Too high levels may negatively impact cognition. Crucial to healthy levels are proper B vitamins and sufficient micronutrients.

Stress and Digestion

  • Stress Response: Stress signals the release of cortisol, which negatively affects the immune system and interferes with digestion, resulting in changes in peristalsis (constipation or diarrhea).

  • Chronic Stress Impact: Changes gut bacteria, mucosal lining, enzyme production, nutrient absorption, and can lead to various health issues.

Natural Digestive Aids

  • Zinc: Necessary for enzyme production and HCl release. Deficiency impairs nutrient absorption.

  • Bitters: Stimulate digestive juices and enzyme production. Enjoy before meals. Examples include dandelion greens, endive, mustard greens, etc.

  • Apple Cider Vinegar: Enhances digestion, stomach acidity, and nutrient absorption. May support good bacteria and reduce joint pain.

Prebiotics and Probiotics

  • Prebiotics: Food for probiotics. Derived from fibrous foods; examples include onions, bananas, and berries.

  • Probiotics: Microbial communities can be repopulated by consuming foods naturally rich them, or by supplement. Crucial in restoring gut health and replenishing good bacteria.

  • Fermented foods (yogurt, kefir, pickles, sauerkraut, kimchi, miso): Contain probiotics and may be detrimental to those with gut issues (IBS, SIBO, Candida).

Phytic Acid

  • Phytates: Found in legumes, grains, and nuts. Bind to minerals (iron, zinc, calcium) decreasing absorption, necessary for seed germination. Pro-inflammatory and antioxidant properties as well.

  • Preparation: Soaking, fermenting, or sprouting reduces its negative impacts.

Bone Broth

  • Benefits: Supports overall digestion, intestinal lining, bones, muscles, tendons, ligaments, and skin; bolstering the immune system. Plant-based broths are also beneficial.
