> A diet of corn, beans, and squash is complete and balanced. I've run this though cronometer.com (what nutritionists use) while trying different types of beans, the following vitamins/minerals came out low: * Zinc * Selenium * Sodium - they probably had a source of salt * VitB2 * VitB12 - this is abundant in unrefined surface water * VitK I expected magnesium to be low, due to the omission of green leafs. But corn ( I rarely eat) turn out to be a great source, and squash is not too shabby either.

> Zinc * Selenium * Sodium I would be hesitant with taking mineral content seriously in produce. Plants obviously don't make minerals so mineral content is mostly a factor of soil quality and characteristics. Yes different plants have different propensities to take up different minerals, but we've seen an overall decrease in mineral content across the board since at least 1940: > All elements except P declined in concentrations between 1940 and 2019 - the greatest overall reductions during this 80-year period were Na (52%), Fe (50%), Cu (49%) and Mg (10%); water content increased (1%) https://pubmed.ncbi.nlm.nih.gov/34651542/ https://pubmed.ncbi.nlm.nih.gov/34651542/

  Since produce is often bred for looks and size, they might jave the same amount but lower percentages of nutrients than older varieties bred for taste/hardness.

    And yield of course - which is size to some extent but also heavy cropping per plant, lots of (ideally big) aubergines not 3, for example. If you grow your own how many do you really need, you can pick a variety for taste instead.

  > I would be hesitant with taking mineral content seriously in produce. But it still requires some minerals in some quantities to make a broccoli. It's true that it decreased (which is in part already factored into cronometer's data), but that's not to say that it is devoid of minerals. Also, if not from produce, where from then? Pills? They seem to have more problems than produce (sometimes badly absorbed, Mg-searate is everywhere in pills and disputed). If it in the worst cases reduced by 50% in produce, I will just eat double doses :)

re: Zn Se and Na - You're gonna need other grains, nuts, seeds, fish, meat, or table salt to get those.

  One brazil nut per day i take for my Sn fix.

The obvious thing it's low in is fat.

  10 caloric% fat is enough. It's what apes get.
