Man, "creature of air and sun", has always put the respiratory function over the digestive function, i.e. he has always believed that to live well it is enough to "eat well" (which in the vulgar concept means precisely to eat too much, irrationally, or in short "to eat badly") and has never stopped his attention to these simple and incontrovertible facts — 1.
