While the treatment of cancer is of vital importance, its elimination by scientific dietetic measures is vastly more urgent. I have repeated on innumerable occasions in the last forty years that I have never operated on a case of cancer in a healthy subject — in other words, a healthy individual cannot be infected by the virus of cancer, however old he or she may be.”.

“Save for hereditary maladies and accidents, is there any reason why we should not all live to be centenarians ? Biologists have propounded various theories to explain longevity, but we are here concerned with practical issues. Duration of life in the vegetable and animal kingdoms varies from a few hours in the case of some insects to thousands of years in the case of the giant Sequoia trees of California.

Tortoises, parrots and swans are notoriously long-lived, while the sacred crocodiles of India are believed to live for more than a hundred years. With human beings there is a marked variation in the span of life, according to race and climate. A recent census at Sofia states that there are 158 centenarians in Bulgaria — all peasants from the rough mountainous areas, of whom 95 per cent. have been vegetarians all their lives, drinking large quantities of yoghurt, while only 2 per cent. eat meat regularly.

In this connection the case of Thomas Parr, whose autopsy was performed by William Harvey, the discoverer of the blood circulation, may be mentioned. This Shropshire peasant, who did public penance for incontinence, after he had passed his hundredth year, is recorded to have died in his 153rd year (that is probably apocrypha, but there is no doubt that he attained a great age), and it is interesting to observe that his ordinary diet consisted of sub-rancid cheese, and milk in every form, coarse and hard bread, and small drink, generally sour whey.

There is incontrovertible evidence for the belief that old age is precipitated by absorption of the products of putrefaction from the large bowel. This view was originally suggested by Metchnikoff, who urged that the germs of putrefaction could be replaced or suppressed by certain lactic acid germs present in soured milk, thus inhibiting the putrefaction and preventing the self poisoning which is the chief agent in the senile degeneration of the tissues.”.

“The time will come when centenarians will no longer be so rare as to be subject for comment, and when their appearance will believe their great age if judged by our present conceptions. Mr. Henry Ford has recently announced his determination to live to be a hundred years of age, and to be of service to himself and mankind until he is eighty-five; while Professor Guenoit, the oldest French doctor, who has just celebrated his ninety-eighth birthday, holds that any normally constituted person should be able to live for 100 years of more.

Both declare that most people eat too much, especially too much meat, and both pin their faith to the simple life. A man does not die a natural death as a rule, but kills himself by a gradual process of poisoning, asserts Professor Guenoit; and that is the writing on the wall for all who would live to be healthy centenarians.”.

“Compared with their sisters of past generations our modern women are immeasurably more vigorous and vital. Their athletic figures enable them to indulge in nearly every kind of outdoor sport with most desirable benefits to their health. Nowadays, a woman is no longer content to be old at forty. If her dressmaker as much as hints at a spreading figure, she immediately takes herself in hand and consults the weighing machine with anxious regularity until satisfied that all danger is over.

W. Arbuthnot Lane
Sir William Arbuthnot Lane, Bt, CB, FRCS, Legion of Honour (4 July 1856 – 16 January 1943), was a British surgeon and physician. He mastered orthopaedic, abdominal, and ear, nose and throat surgery, while designing new surgical instruments toward maximal asepsis. He thus introduced the "no-touch technique", and some of his designed instruments remain in use.
Lane pioneered internal fixation of displaced fractures, procedures on cleft palate, and colon resection and colectomy to treat "Lane's disease"—now otherwise termed colonic inertia, which he identified in 1908—which surgeries were controversial but advanced abdominal surgery.
In the early 1920s, as an early advocate of dietary prevention of cancer, Lane met medical opposition, resigned from British Medical Association, and founded the New Health Society, the first organisation practising social medicine. Through newspapers and lectures, sometimes drawing large crowds, Lane promoted whole foods, fruits and vegetables, sunshine and exercise: his plan to foster health and longevity via three bowel movements daily.
