75% മലയാളികൾക്കും പാൽ ദഹിക്കാത്തതെന്തുകൊണ്ട്? Lactose Intolerance Explained.

🔥 Did you know that over 75% of Malayalis cannot properly digest milk? This is not a modern problem — it’s written in our DNA! In this video, we explore the surprising science behind lactose intolerance, and why it’s far more common in South India and East Asia than in other parts of the world. 💡 You’ll learn: Why most mammals — including humans — lose the ability to digest milk after childhood How a rare genetic mutation allowed some ancient populations to continue drinking milk The difference between lactose persistence and lactose intolerance How this mutation spread through Northwestern India but stayed rare in Kerala and Tamil Nadu And whether being lactose intolerant means you must avoid dairy altogether! 🧬 We’ll also uncover the role of Chromosome 2, the LCT gene, and the MCM6 region — the invisible genetic factors that decide whether your body can process milk or not. 📊 Using data from genetic studies and population maps, we’ll show how geography, culture, and evolution all came together to shape India’s dietary habits. #LactoseIntolerance #Lactose #Milk #LactasePersistence #HealthFacts #ScienceExplained #HumanEvolution #MalayalamScience #KeralaHealth #DigestionProblems #GutHealth #DietTips #DidYouKnow #LactoseIntolerance #MalayalamScience #ScienceForMass #LCTGene #MilkMyth #KeralaHealth #SouthIndiaFacts #GeneticsExplained #DidYouKnow #ScienceMythsBusted You are welcome to my Malayalam Science Channel, Science 4 mass (Science for mass). My name is Anoop. I am a science enthusiast. My science talk videos are an attempt to simplify complicated science topics so that everybody can understand. My videos will include topics like Physics, Astrophysics, Astronomy, Black Holes, Special Theory of relativity, General Theory of relativity, Space time, Stars, Quantum Physics, Science experiments, Science projects, Technology, Biology, Aliens, Science facts, Science Documentary etc. I will try to explain science in a simple way without too much of equations, formulas and graphs. Some of my videos may be useful for Science students, Science class, Science master, and competitive exams students like UPSC etc. ഞാൻ, ശാസ്ത്രത്തിൽ താല്പര്യം ഉള്ള ഒരു സാധാരണക്കാരനാണ്. ശാസ്ത്ര വിഷയങ്ങൾ ലളിതവത്കരിച്ചു സാധാരണക്കാർക്കു മനസിലാക്കികൊടുക്കാൻ വേണ്ടിയാണു ഈ ചാനൽ.
