My understanding is that the largest part of expenditures on health is generally at end of life, at least in developed countries, rather than spending a smaller amount on disease prevention earlier in life, which would be expected to have a larger effect on morbidity and mortality.

John Jeavons book, How to Grow More Vegetables (than you ever thought possible on less land with less water than you can imagine) is a wonderful reference on the biointensive method (https://johnjeavons.org/books-and-videos/). And it's now in it's 9th edition.
Thank you Justice Kagan!
