It is a great delusion to suppose that flesh-meat of any kind is essential to health. Considerably more than three parts of the work in the world is done by men who never taste anything but vegetable, farinaceous food, and that of the simplest kind. There are more strength-producing properties in wholemeal flour, peas, beans, lentils, oatmeal, roots, and other vegetables of the same class, than there are beef or mutton, poultry or fish, or animal food of any description whatever.
