>In this cohort study of 390 124 generally healthy adults with more than 20 years of follow-up, daily multivitamin use was not associated with a mortality benefit. Aren't most of them the kind of people that are generally middle class and above types, with access to better nutrition and healthcare, and the associated mindset for health improvement, that's a prerequisite to consistently buy and consume multivitamins? That is, the kind of people to not have many vitamin deficiencies to begin with, compared to some working class person who can't afford time to cook, nor had such ideals instilled upon them since childhood, and eats fast food and microwaved stuff 24/7... I'd like to see how e.g. adding multivitamins to industrial foodstuff consumed by poorer families, in the school lunches of poor districts, and so on, improves or doesn't improve health outcomes...

I do believe you’re describing food fortification, which the US performs liberally: https://en.m.wikipedia.org/wiki/Food_fortification#United_States https://en.m.wikipedia.org/wiki/Food_fortification#United_St... I’d honestly be curious to see if this study accounted for socio-economic class and overall policy around food enrichment or fortification in the regions the participants lived in. I’d expect multivitamins to have a more noticeable impact in places where food wasn’t enriched.

  Vitamins are naturally present in good non-processed food. Fortification is only required in processed food.

    Not disputing that, but the line gets blurry when you consider things like golden rice (https://en.wikipedia.org/wiki/Golden_rice https://en.wikipedia.org/wiki/Golden_rice) as a method of food fortification. The purpose for golden rice touches on a big consideration for nutritional policy: diets aren't always diverse and don't always include enough sources of nutrition. History is rife with stuff like beriberi or scurvy due to cultural norms or inability to find varied sources of nutrition.

> Participants were adults in the National Institutes of Health–AARP Diet and Health Study (NIH-AARP) cohort; the PLCO Cancer Screening Trial cohort; and the Agricultural Health Study (AHS) cohort (eFigure 1 in Supplement 1).

That sounds like more a broader approach then just "middle class and above types".
