Thomas Richard Allinson (19 May 1858 – 1918) was a British doctor, dietetic reformer, businessman and journalist. He was a proponent of whole grain (or "wholemeal") bread consumption. His name is still used today for a bread popular in Europe, Allinson bread.
Allinson was born in the Hulme district of Manchester on 19 May 1858. He went to school in Lancaster and Manchester and at age fifteen began work as a chemist's assistant. With money he saved and financial help from his stepfather, he was able to attend the extramural medical school in Edinburgh, which was less expensive than the University medical school. He graduated as a Licenciate of the Royal Colleges of Physicians and Surgeons of Edinburgh (LRCP, LRCS) in 1879 at the age of 21 years. After assistantships in Hull and the East End of London he established his own practice in Marylebone in 1885.
During the 1880s Allinson developed his theory of medicine, which he called Hygienic Medicine. In place of orthodox medicine, he promoted health through diet, exercise, fresh air and bathing. He advocated a vegetarian diet and the avoidance of alcohol, tobacco, coffee and tea. He especially promoted the benefits of stone-ground whole grain breads. He opposed the use of drugs by doctors, many of which at that time were ineffective and toxic and was a lifelong opponent of compulsory vaccination against smallpox. He became medical editor of the Weekly Times and Echo in 1885, for which he wrote over 1000 articles during his life, as well as answering readers' medical queries.
He wrote a number of books and pamphlets directed at a general rather than medical readership, including A System of Hygienic Medicine (1886), How to avoid Vaccination (1888), The Advantage of Wholemeal Bread, Medical Essays and A Book for Married Women (1894) and books on stomach diseases, consumption (tuberculosis), rheumatism, vegetarian cooking and healthy diet. He gave frequent public lectures throughout the country propounding his ideas. In one of his books, The Advantages of Wholemeal Bread (1889), he proposed that whole grain bread was healthier than white (or refined) bread. He believed that smoking was a cause of cancer, which was a radical idea at the time. Allinson regularly sought publicity for his theories and practices in the press and directed his energies not just towards his colleagues but directly to the public.
