The physiology of digestion considered with relation to the principles of dietetics…
(1836)
“ The vigorous appetite, which is perfectly natural during a period of growth and great bodily activity, remains at first unimpaired, and impels the individual to eat an amount of food far beyond the present necessities of the system or the powers of digestion. The consequence is a tendency, not only to fulness from excessive nutrition, but to severe digestive disorder from the stomach and intestines being weakened both by want of exercise and by excess of food. I have known many instances of dyspepsia, constipation, and mental affection, and even of active inflammation, thus produced. ”
