Dr. Salisbury's career also serves to remind us that a mixed diet is not necessary for the physical welfare of those who eat to live. Vegetarians dwell upon the toxicity of meat. But Dr. Salisbury fed his patients on nothing but meat and water, and the percentage of recoveries in chronic diseases was considered remarkable. Meat is very easy to digest and when prepared in the simple manner prescribed by the doctor and eaten by itself it will agree with nearly everybody. But when eaten with soup, bread, potatoes, vegetables, cooked and raw, fish, pudding, fruit, coffee, crackers and cheese, there will be overeating followed by indigestion and its consequent train of ills. However, it is not fair to blame the meat entirely, for the whole mixture goes into decomposition and poisons the body.

The cures resulting from Dr. Salisbury's plan also help to disprove the much heralded theory of Dr. Haig, that uric acid from meat eating is the cause of rheumatism. Overeating of meat is often a contributory cause. We are told that the rheumatics who followed Dr. Salisbury's plan got well. They regained physical tone. They lost their gout and rheumatism. They parted company with their pimples and blotches. All of which would indicate that the blood became clean.

The chief lesson derived from Dr. Salisbury's plan and experience is the helpfulness of simple living and moderation. An exclusive diet of meat is not well balanced. Energy produced from flesh food is too expensive. The good results came from substituting habits of simplicity and moderation for the habit of overeating of too great variety of food. The same results may be obtained by putting a patient on bread and milk.

Dr. Salisbury's patients had unsatisfied longings, doubtless for various tissue salts. The addition of fresh raw fruits or vegetables would improve his diet, for apples, peaches, pears, lettuce, celery and cabbage are rich in the salts in which meats are deficient.

Dr. Emmet Densmore recommended omitting the starches entirely, that is, to avoid such foods as cereals, tubers and legumes. He believed that it is best to live on fruits and nuts. He recommended the sweet fruits--figs, dates, raisins, prunes--instead of the starchy foods. The doctor did much good, as everyone does who gets his patients to simplify. He also had good results before discovering that starch is a harmful food, when he fed his patients bread and milk.

Starch must be converted into sugar before it can be used by the body. The sugar is what is known as dextrose, not the refined sugar of commerce. The sweet fruits contain this sugar in the form of fruit sugar, which needs but little preparation to be absorbed by the blood. Dr. Densmore reasons thus: Only birds are furnished with mills (gizzards); hence the grains are fit food for them only. Other starches should be avoided because they are difficult to digest, the doctor wrote.

Raw starches are difficult to digest, but when they are properly cooked they are digested in a reasonable time without overburdening the system, provided they are well masticated and the amount eaten is not too great and the combining is correct. Rice, which contains much starch, digests in a short time.

We can do very nicely without starch. We can also thrive on it if we do not abuse it. The two chief starch-bearing staples, rice and wheat, contain considerable protein and salts in their natural state. In fact, the natural wheat will sustain life for a long time. Man has improved on nature by polishing the rice and making finely bolted, bleached wheat flour, deprived of nearly all the salts in the wheat berry. The result is that both of them have become very poor foods. The more we eat of these refined products the worse off we are, unless we partake freely of other foods rich in mineral salts.

Not long ago a lady died in England who was a prominent advocate of a "brainy diet." Her brainy diet consisted largely of excessive quantities of meat, pork being a favorite. She died comparatively young, her friends say from overwork. Such a diet doubtless had a large part in wearing her out. To overeat of meat is dangerous.

A gentleman is now advocating a diet of nothing but cocoanuts. This is a fad, for they are not a balanced food. He has published a book on the subject. Perhaps his advocacy is influenced by his interest in the sale of cocoanuts.

The vegetarians condemn the use of meat. Some of them are called fruitarians. It is very difficult to decide who are the most representative of them. Some advocate the use of nothing but fruit and nuts. Others add cereals to this. Others use vegetables in addition. Some even allow the use of dairy products and eggs, that is, all foods except flesh.

They say that meat is an unnatural food for man and condemn its use on moral grounds. It is difficult to decide what is natural, for we find that man is very adaptable, being able to live on fruits in the tropics and almost exclusively on flesh food, largely fat, in the arctic regions. In nature the strong live on the weak and the intelligent on the dull. There is no sentiment in nature. In her domain might, physical or mental, makes right. Sentiments of right and justice are not highly developed except among human beings, and even there they are so weakly implanted that it takes but little provocation for civilized man to bare his teeth in a wolfish snarl.

With some vegetarianism is largely a matter of esthetics, ethics and morality. Morality is based on expediency, so it really is a question whether meat is an advantageous food or not.

Another vegetarian argument is that man's anatomy proves that he was not intended by nature to eat meat. Good arguments have been used on both sides, but they are not very convincing nor are they conclusive. It is hard to draw any lines fairly.

Another objection to meat is that it is unclean and full of poisons, that these poisons produce various diseases, such as cancer. We are also informed that refined sugar causes cancer, and the belief in tomatoes as a causative factor is not dead. Cancer is without doubt caused principally by dietary indiscretions but it is impossible to single out any one food.
