Study Notes

Digestion: Where it All Begins

  • Tongue: Thoughts and emotions impact digestion. Eating delicious food is important for digestive health.

  • Salivary Glands: Saliva lubricates the mouth and contains amylase (breaks down carbs) and lingual lipase (breaks down fats). Chewing thoroughly before swallowing improves digestion duration.

  • Stomach: Continuously stretching the stomach disrupts brain signals regarding hunger and fullness. Leptin signals take ~20 minutes to reach the brain; chewing well allows this. Overeating desensitizes leptin signals. Mechanical and chemical reactions break down food. Different foods have different digestion times (fats, proteins, and fiber are slowest). Eating slowly helps address interference of signals.

  • Small Intestine: 90% of digestion and nutrient absorption occurs here. Nutrients are transported into the bloodstream. Different sections (duodenum, jejunum, ileum) absorb different nutrients. The migrating motor complex (MMC) cleans the gut when empty, interrupted by snacking. Carbohydrates absorb quickly. Intermittent fasting and avoiding snacks can help.

  • Liver & Gallbladder: The liver produces bile, the gallbladder stores and recycles it, aiding digestion.

  • Pancreas: Releases enzymes (amylase, lipase, proteases) breaking down proteins, fats, and carbs. Also neutralizes stomach acid with sodium bicarbonate.

  • Large Intestine: Houses a vast microbiome. Probiotics digest fiber and sugars, producing short-chain fatty acids (SCFAs). Vitamin K and biotin (B vitamin) production occurs here. Gas production is natural, don’t hold it in. Digestion takes 8-72 hours.

  • Constipation: Causes include IBS, SIBO, dehydration, enzyme/magnesium deficiencies, gallbladder removal, stress, and emotional factors. Remedies: fiber-rich foods, psyllium husk, water, exercise, stress reduction, probiotics.

  • Diarrhea: Results from inadequate liquid reabsorption, excessive fiber, or food sensitivities/allergies, and stress. The body expels substances quickly.

Microbiota

  • Composition: Microbiota becomes stable by age 2-5. ~1000 different species; ⅓ are common to most, ⅔ are unique. Changes with puberty, pregnancy, and menopause impact energy and feelings.

  • Diet & Microbiota: Fiber, from complex carbs, is needed for gut bacteria. Bacteria in the large intestine ferment fiber.

  • Influence: Microbiota influences digestion, metabolism, weight regulation, food choices, energy, hunger hormones, blood sugar, immune system, sleep, mental health, thyroid function, inflammation, and cancer, immunity, heart disease, obesity, type 1&2 diabetes, autism, sensitivities, allergies, eczema, autoimmune diseases, depression, headaches, constipation, colitis and more.

  • Interfering Factors: Antibiotics, medications, herbicides, pesticides, household chemicals, diet, water, air, lifestyle, age, lack of exercise, stress, processed foods, antibiotics in livestock, travel (disrupts circadian rhythm), and smoking change microbiota composition.

Leaky Gut & Gut & Immune System

  • Leaky Gut: Gut lining compromised, allowing undigested foods, bacteria, and toxins into bloodstream. Repaired with a healing diet.

  • Gut & Immune: 80% of immune system is in the gut. 85% good bacteria, 15% bad bacteria is a health balance. Microbiota educates the immune system to distinguish good/bad microbes and threats.

Inflammation

  • Inflammation: The body’s natural response to injury, with signs including heat, pain, redness, and swelling. It’s designed to protect and heal.

  • Chronic Inflammation: Many people have low-level chronic inflammation, a precursor to disease. Triggers: processed foods,refined sugars,omega-6 oils,environmental toxins, stress, lack of sleep, negative self-talk, food allergies, alcohol, and lifestyle choices. Treating this with anti-inflammatory drugs short term is ineffective. Using anti-inflammatory foods is more effective.

  • Anti-Inflammatory Foods: Vegetables, fruits, fish, ethically raised animal products, pre/probiotics, fermented food, omega-3s (fish oil), herbs/spices (turmeric, ginger, garlic).

Gut-Brain Axis (GBA) & Neurotransmitters

  • GBA: The connection between gut bacteria and brain functioning. The vagus nerve is a communication highway between gut and brain. Stress/anxiety from gut to brain or mental stress/anxiety to gut can disrupt digestion. Importance of balance of good gut bacteria alters behaviour, mood, brain activity, and more.

  • Neurotransmitters (NTs): Many brain chemicals are made in the gut. The gut contains twice as many neurotransmitters as the brain. Serotonin (mood, emotions) and dopamine (motivation, focus) are made in the gut (90% and 50%, respectively). All macronutrients needed for proper function. Depletion of vitamins, minerals, excess caffeine/alcohol can negatively impact NT production.

  • Serotonin: Made from tryptophan; B vitamins (B6, B12) required for synthesis. Found in poultry, dairy, eggs, fish, bananas, almonds, oats, legumes, fermented soy. Complex carbs also increase serotonin.

  • Dopamine: Made from tyrosine; antioxidants important. Meat, dairy, almonds, sesame seeds, avocados are sources. Lack of sleep, stress, excess sugar/caffeine can affect dopamine.

  • Stress & Digestion: Chronic stress puts strain on the digestive system. Stress increases cortisol, lowers serotonin, and interferes with inflammation mediators. It can cause constipation/diarrhea and impair nutrient absorption. Nutrients (Mg, Zn, Fe, K, chromium, vitamins A, C, E, and B’s) are used up in response to stress.

Natural Digestive Aids, Phytic Acid, Bone Broth

  • Digestive Aids: Zinc is essential for digestions enzyme and HCl production; deficiency impairs nutrient absorption. Bitters stimulate digestive juices (saliva, bile, enzymes) before meals. Apple cider vinegar stimulates stomach acid, helps control blood sugar, and may help repopulate good bacteria.

  • Phytic Acid: Found in legumes, grains, nuts. Inhibits mineral absorption but has antioxidants and other benefits. Soaking, fermenting, or sprouting deactivates phytic acid. Preparation is important, especially for a plant based diet or children.

  • Bone Broth: Contains essential amino acids, gelatin, collagen, and glutamine. Supports overall digestion, intestinal function, and mucosal lining health. Promotes bone, muscle, ligament, tendon, and skin health, as well as the immune system. A daily addition is beneficial. Plant-based broths are also beneficial.
