I’d be fairly cautious about using popular reception as a metric in this case, books which appear to be a breezy, comprehensive take on a given subject(“Guns, Germs and Steel”,”Sapiens”,”Zealot” and the like) tend to be very well received popularly but largely derided by subject matter experts. I would generally recommend either an academic in the field you’re interested in who also writes popular texts(a Bart Ehrman or Irving Finkle for example) or else just find an online community of scholars in the field you’re interested in and ask what their recommendations for a layperson delving into the field is.

Sorry I don’t have any more specific recs for you, nutritional science isn’t really one of my areas of interest.
