By partaking freely of stewed acid fruits and vegetables at the same meal, or by blending a great variety of savouries, vegetables, sweets and rich fatty dishes together in a ghastly 'pot pourri,' or by eating to excess of porridge, beans, or fried dishes, many have made serious blunders. They, for want of proper instruction, have hastily come to the conclusion that "vegetarian diet does not suit them," and returning to the flesh-pots, have henceforth denounced the evangel of dietetic reform, instead of profiting by the useful lesson Nature tried to teach them. The wisest plan is to make one's diet generally _as varied as possible_, but not to mix many articles together _at the same meal_. Abstainers from flesh should begin to live to some extent (say two days a week) in picnic style, and the practice will soon become more habitual. A picnic luncheon which is considered enjoyable in the woods or on the moors will be found to be just as nice at home if the articles provided are well chosen and tastefully prepared. Variety can be obtained by introducing daintily cut sandwiches made with mustard and cress, tomato paste, potted haricots, or lentils, scrambled eggs, fancy cheese cut thinly, flaked nuts and honey, etc. Fresh and dried fruit, nuts, almonds, raisins and sultanas, fruit cakes, and custard or rice puddings, provide useful additions; and it will soon be found that the old-fashioned three or four-course meal which involves such laborious preparation is a needless addition to life's many cares. [Sidenote: =Necessary Elements in Food.=] It is important to bear in mind that our daily food must contain a sufficient quantity of certain necessary elements: (1) PROTEIN. To be found in nuts and nut foods (such as Protose, Nuttoria and Fibrose, &c.), eggs, cheese, brown bread, oatmeal, haricots, lentils and peas. (2) FAT. To be obtained in nuts, nut-butters, olive oil, cheese, milk, cream, butter, and oatmeal. (3) PHOSPHATES AND MINERAL SALTS. Contained in the husk of wheat, barley, oats, and rye (therefore included in brown bread, granose biscuits and other whole-wheat or cereal preparations), cheese, bananas and apples. (4) SUGAR. To be obtained from all starch foods, but most easily and in the best and most readily assimilable form from sweet fruits and honey. =A PLEA FOR MODERATION.= [Illustration: Do not dig your grave with your teeth!]
