India ran the most important cardiovascular study of the 20th century by accident, and then immediately forgot about it.
In 1967, Dr. S.L. Malhotra published a study in the British Heart Journal examining heart disease rates among 1.5 million Indian railway employees. The population was extraordinarily useful for research purposes: same employer, same healthcare access, comparable income and working conditions, spread across the entire country.
The only meaningful variable was geography. Which meant diet.
North Indian railway workers: Punjab, Rajasthan, UP, ate a diet built around ghee and dairy fat. They consumed up to 19 times more fat than their southern counterparts. The fat was primarily saturated: clarified butter, milk fat, the short-chain saturated fatty acids that Ancel Keys had recently been telling the Western world were arterial death.
South Indian railway workers ate a diet based on rice, sambar, and seed oils: groundnut oil and sesame oil, primarily. They ate considerably less fat overall. By the standards of dietary advice being formulated in the 1960s, they should have been the healthy ones.
Heart disease mortality in South India: 135 per 100,000.
Heart disease mortality in North India: 20 per 100,000.
Seven times higher in the population eating seed oils.
Among railway sweepers specifically, the lowest-paid, most physically active workers, the gap was even wider. Heart disease was fifteen times more common in the South Indian sweeper population than in the North Indian sweeper population.
Malhotra controlled for everything he could reach: smoking, where Northerners actually smoked more. Activity levels, where the relationship was inconsistent. Socioeconomic status, where executives died more often than sweepers regardless of region. He found no variable that explained the gap except the type of fat in the diet.
He published the data. In a peer-reviewed journal. In 1967.
The study was cited periodically, acknowledged as methodologically interesting, and then set aside.
The decade in which Malhotra published was the decade in which Ancel Keys's fat hypothesis was being converted into policy. The American Heart Association was issuing guidance recommending polyunsaturated vegetable oils as replacements for saturated animal fats. The food industry was producing seed oils at industrial scale. The infrastructure of seed oil promotion was being built, expensively and with great institutional momentum.
A study showing that populations eating animal fat had a fraction of the heart disease of populations eating seed oils was not, in that context, a study that anyone particularly wanted to follow up.
Nobody followed up.
Almost sixty years later, the finding stands unrefuted in the literature.
It is not in the dietary guidelines.
@krithikasivasw Wow... What a stark contrast to yesterday's kaalapramanam! This simply transcends one to the aradhana days of MS, DKP, TB, ARI, MLV! Thanks for sharing...
This is what happens when immunisation programs falter. Sad to see a completely preventable infection coming back so quickly & killing children (who did not choose to remain unvaccinated).
Follow the Science!
I failed IIT twice. Took loans I couldn't afford. Started as a Quality Engineer while my friends climbed faster. 25 years later, here's the timeline:
2000: Decided to become an Engineer from IIT
2004: Failed to get into IIT
2005: Failed to get into IIT a second time—reluctantly took admission in another engineering school
2006: Started preparing for grad school in US
2008: Ran around trying to get a loan to go to grad school.
2009: Graduated with an engineering degree in India
2009: Moved to the US for grad school at UPenn, started from scratch in a new country
2010: Struggled landing an internship, while all my friends had one.
2010: Clock was ticking on student loan installments
2010: Finally got an internship at a tiny startup
2011: Finally landed a job at the same startup
2012: Struggled through tech career beginnings as a QA engineer
2013: Doubted if I belonged, took a leap into customer-facing engineering
2014: Really felt like I'd arrived in my happy place—solving new business problems every day with engineering
2017: Google found me!
2019: Found this role called DevRel, found my love for learning out loud
2020: Launched some cool zero-to-one products
2021: Became a published best selling author
2023: Led Developer Advocacy for North America at Google Cloud
2024: Microsoft found me to lead Developer Strategy for GTM!
2025: Earned Wharton MBA, launched another best selling book, took the TED stage while building and leading a team with multi-billion dollar impact.
Story goes on...
The entire time, one truth kept me going: I had to believe in myself before anyone else would.
Failing IIT twice felt like the end of the world. But it wasn't my destination—it was just the beginning.
From a "Not-IIT" engineering school to leading developer strategy at the
world's biggest tech companies wasn't about being the smartest person in the room.
It was about showing up consistently, learning relentlessly, and never letting failure or fear make my decisions.
Don't give up on yourself. Your timeline is your own. Dream!
Dream big! You can only achieve what you can imagine..so don't hold back.

@ArtSivasri Some historians claim it's the West "Gopuram" (not vimanam) of Madurai that was initially adopted as the emblem. But due to poor quality of paper those days, ink smudges and the gopuram shape became unclear. Thus, people thought of this to be SV Gopuram, and it stayed the same!!
