Martin Hum (PhD, DHD)
Martin Hum PhD DHD is a qualified nutritional therapist with 20 years’ experience, who has written on health and nutrition issues for national magazines and has been a regular contributor to the Health Sciences Institute newsletter for many years. He also appeared on television in the documentary series “Get Well Soon”, which explored the role of natural therapies in preventing and treating illness.
Martin first became interested in nutrition and health in the 1970s, while studying agricultural zoology at university. He realised that farmers were adept at keeping their livestock healthy by adjusting their feed and wondered why the same approach could not apply to humans. He went on to investigate human dietary evolution and the link between food and longevity, before training as a nutritional therapist.
In his private practice, Martin advised clients with a wide range of health concerns, during which he gained a detailed appreciation of the importance of blood sugar control and the role of the hormone insulin in many aspects of human health. In particular, he was able to use cutting edge research findings to help people with type 2 diabetes, metabolic syndrome and polycystic ovary syndrome. Martin was an early proponent of the low carbohydrate diet as a therapeutic approach.
Martin now devotes his time to writing articles and raising public awareness of the link between nutrition and health. He is currently Chairman of the Institute for Optimum Nutrition (ION) and editor of Optimum Nutrition magazine. The ION is a charity that provides training courses for nutritional therapists and education for the public on keeping healthy through good nutrition.
