“Byrne. Six books of Euclid” is a good place to start. It was a book that explains math in graphical form. It taught its reader to think in form and colors, and not numbers or letters. It is all about the portion, not the substance.
The main 5 nutrition (carbs, protein, vitamin from veggies/fruit, and fat) is the things that we really needed on a daily basis, not really about the substance of it (i.e.: carbs are not only coming bread or pasta, it can also be banana or oats).
