It is possible, by careful selection, and by taking a great deal of trouble, to supply all the elements of the body from animal foods alone, or from vegetable foods alone.
But practically, it has everywhere, and in all ages, been found that the best and most healthful diet is a proper combination of animal and vegetable foods.
For e.g. Our Starches, for instance, which furnish most of our food fuel, though give us comparatively little, to build up or repair the body are found, as we have seen, in the vegetable kingdom, in grains and fruits; while most of our Proteins and Fats, which chiefly give us the materials with which to build up, or repair, the body, are found in the animal kingdom. There is no advantage whatever in trying to exclude either animal food or vegetable food from our dietary. Both animal and vegetable foods are wholesome in their proper place, and their proper place is on the table together.
