The preceding bill of fare is not formulated to be followed with dogmatic precision. Its object is to establish principles of practical application, so as to be readily grasped by the reader. The points, however, that should be strictly observed in any combination of foodstuffs, are to avoid milk as a table beverage, and fruit in combination with meat, boiled cereals, or vegetables. On the other hand, fruit may be combined with cheese, dextrinated, i.e., hard-toasted or twice-baked bread, raw starch-free vegetables, and even with cow's milk - providing the latter is taken alone, blood-warm, at a time when the stomach is empty. The milk should be slowly sipped, and followed by the fruit, with an interval of some five or ten minutes. As further important restrictions, it should be mentioned not to take cooked fruit and cooked vegetables at the same meal, nor two starches in the form of potatoes, bread or mushes in combinations at one meal. Hence, bread and mush, bread and potatoes, bread and rice, etc., by virtue of their incompatibility and excess, will give distress to the weak stomach. Animal fats, pork, lobster (all shell fish) - the meat of the latter being poisoned by their character as scavengers - veal (being unripe meat), and asparagus (an unripe vegetable), should be avoided in the careful diet.
