Digestive Enzymes and Food Intolerance: What Actually Helps vs. Hype

Targeted digestive enzymes can help specific intolerances—lactase for lactose and alpha-galactosidase for bean-related gas—while broad blends and betaine HCl have limited evidence. Prescription pancreatic enzymes are effective for true pancreatic insufficiency. Traditional aids like ginger, bitters, and CCF tea may complement modern strategies.

L‑Glutamine for Recovery and Gut Health: Inside the Gut–Muscle Axis

Glutamine sits at the crossroads of muscle, gut, and immune function. Here’s what research says about its role in athletic recovery, gut barrier integrity, immune health in athletes, burn/trauma care, and IBS—with a bridge to the traditional bone broth perspective.

Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a chronic, relapsing disorder of gut–brain interaction characterized by abdominal pain associated with altered bowel habits, without structural disease that explains the symptoms. Western medicine classifies IBS using the Rome IV criteria: recurrent abdominal pain, on average, at least 1 day per week in the last 3 months, associated with two or more of the following—related to defecation, associated with a change in frequency of stool, and associated with a change in form (appearance) of stool—with symptom onset at least 6 months before diagnosis. Subtypes are defined by predominant stool pattern: diarrhea-predominant (IBS-D), constipation-predominant (IBS-C), mixed (IBS-M), and unclassified. Pathophysiology is multifactorial: visceral hypersensitivity, altered motility, immune activation and barrier dysfunction, dysbiosis, bile acid malabsorption in a subset, and central modulation via the gut–brain axis. Psychosocial stressors and early life adversity can amplify symptoms through bidirectional brain–gut signaling. Evidence-based Western management is multimodal and personalized. First-line lifestyle strategies include regular physical activity, sleep optimization, and diet. The low-FODMAP diet—temporary restriction of fermentable oligo-, di-, monosaccharides and polyols—has strong evidence for reducing global IBS symptoms when delivered in a structured elimination and reintroduction program (best studied by Monash University). Soluble fiber (psyllium) is recommended in IBS-C and some mixed phenotypes, while insoluble fiber may worsen symptoms. Pharmacologic options are matched to subtype and dominant symptoms: antispasmodics (e.g., dicyclomine, hyoscyamine) for cramping; loperamide for urgency/diarrhea control (not for global symptom relief); bile acid sequestrants in suspected bile acid diarrhea; non-absorbed antibiotic rifaximin for IBS-D; secretagogues such as linaclotide and plecanatide for IBS-C; lubiprostone (women with IBS
