May Mellanby


May Mellanby, née Tweedy was an English medical researcher, styled Lady Mellanby after her husband, Edward Mellanby, was knighted in 1937. As well as nutrition research carried out with her husband, she conducted independent research into the physiology of dentition and the causes of dental disease. She recommended a diet high in Vitamin D and low in cereals to help teeth protect themselves against decay.

She published a series of research papers in the British Medical Journal and the British Dental Journal, some of which were summarized in a chapter of her husband's Nutrition and Disease. She also produced four Special Reports for the MRC.
