Debunking The Internet’s Biggest Health Myths - Dr Karan Rajan

Most digestion happens in the small intestine with the help of the liver, pancreas, gallbladder and microbiome; seeing it as a coordinated ‘factory line’ rather than just a ‘stomach blender’ clarifies why whole‑diet patterns matter more than single foods or quick fixes.

Off‑the‑shelf probiotics usually contain low, poorly regulated bacterial doses that rarely colonize your gut, whereas kefir, live yogurt, sauerkraut and other fermented foods provide richer, more viable microbes with better real‑world benefit for most people.

IBS is an umbrella of subtypes with varied triggers, strongly influenced by microbiome, ultra‑processed diets, sedentary behavior, stress and sleep; personalization and lifestyle changes generally matter more than any single ingredient or supplement.

Genetic ‘clock’ differences mean most healthy adults fall somewhere between ~6–8.5 hours of sleep; chasing an arbitrary eight hours can increase anxiety, so it’s better to learn your own sleep need and protect a stable window with rules around food, screens and caffeine.

You’re born with a finite set of inner ear hair cells and chronic loud exposure irreversibly destroys them, while constant near‑focus on screens promotes eye strain and myopia—so custom earplugs and 20‑20‑20 eye breaks (every 20 minutes, look 20 feet away) are worthwhile baselines.
