LOW STOMACH ACID: THE HIDDEN FACTOR AFFECTING YOUR GUT & IMMUNITY
Stomach acid is often overlooked in discussions about parasites, mold, and heavy metal toxicity. Yet it plays a critical role in digestion, nutrient absorption, and defense against ingested pathogens.
Functions of Stomach Acid
Protein Breakdown: Acid activates pepsin, the primary digestive enzyme for proteins.
Mineral Absorption: Essential minerals like iron, zinc, magnesium, and calcium require an acidic environment for proper absorption.
Defense Mechanism: Adequate acidity neutralizes ingested pathogens, preventing overgrowth in the intestines.
Digestive Signaling: Acid triggers bile and pancreatic enzyme release, essential for fat and carbohydrate digestion.
Consequences of Low Stomach Acid
Increased Risk of Overgrowth: Pathogens and parasites can survive passage to the intestines.
Nutrient Deficiencies: Iron, zinc, calcium, and vitamin B12 deficiencies may develop over time.
Digestive Disturbances: Bloating, gas, and malabsorption of macronutrients can occur.
Toxin Retention: Impaired digestion and gut signaling can exacerbate toxic buildup from mold, metals, or parasites.
Why It Matters for Detox and Immune Health
Low stomach acid can indirectly worsen chronic conditions. Without proper breakdown and absorption, the body’s detox pathways, immune response, and barrier defenses are compromised.
⚠️ While many are taught to take antacids assuming high stomach acid, evidence often points to the opposite being true.
