Had to look up what a phytate was. They look like the kind of thing that’s administered for metal poisoning (chelating agent), so it’s not surprising it hoovers up the essential metals in one’s diet.

This study would be better described as “a diet of not fully nutritious food isn’t fully nutritious”. Like with pet food I guess, the manufacturers can choose ingredients or supplement as necessary or you can supplement them as necessary. The latter, unfortunately, takes more effort and carries more risk.
