'The mystery of why Saloni is so short' - still remains an unsolved question after reading the piece since I don't think any of the proposed mechanisms apply to me 😶

I'll continue with my vague assumption that it has something to do with lactose intolerance and low milk consumption, but unfortunately the prevalence estimates on that topic seem quite poor quality

pic unrelated, that's me on the right

I reread that unquestioningly about 4 times as “why are Indian kids so smart”

An interesting read! My top guesses were parasite load and diet, especially protein consumption. I'm surprised to see we don't have better data on the latter. I wonder if the mid-day meal schemes - which often include eggs - would allow for regression discontinuities that isolate the diet effect?

Could you explain a bit more on the discontinuity? How would a mid-day meal allow you to see a discontinuity on height (since it develops slowly over years)? I'm probably misunderstanding

I was thinking about year of introduction of the mid-day meal. Height at say age 20 as a function of year, could well show a discontinuity at year of introduction of the mid-day meal scheme if diet is a major cause. Year of introduction also differs between states for some added information.
