Early life, family, and education

Mann was born in George, Western Cape, South Africa, on 30 September 1944, the son of Pearl Mann (née Joseph) and Harry Bernard Mann.[2] He studied at the University of Cape Town, graduating MB ChB in 1967, and PhD in 1971.[2] The title of his doctoral thesis was Some factors influencing serum triglyceride in man.[3] He then completed Master of Arts and Doctor of Medicine degrees at the University of Oxford in 1975.[2]

On 28 January 1978, Mann married Helene Vicary Jones, and the couple went on to have two children.[2]

Career

Between 1975 and 1987, Mann was a university lecturer in social medicine at the University of Oxford, and concurrently a consultant physician at the John Radcliffe Hospital.[2] He became a fellow of Wolfson College, Oxford in 1977.[2]

In 1988, Mann moved to New Zealand where he was appointed professor of human nutrition and medicine at the University of Otago,[2][4][5][6] and consultant physician (endocrinology) at Dunedin Hospital.[7] He is also a director of the Edgar Diabetes and Obesity Research (EDOR,[8] a World Health Organization Collaborating Centre for Human Nutrition at the University of Otago) and a principal investigator for the Riddet Institute at Massey University.[9]

Research

Mann and his team at the University of Otago carried out a major review for the World Health Organization (WHO) of the scientific evidence on sugar and weight gain, published in 2013 in the British Medical Journal.[10] The review, which showed that sugar "unquestionably contributes to obesity",[10] "informed WHO guidance on curbing sugar in the diet, leading to sugar taxes around the world."[11]

Mann and his coworkers at Otago carried out a "landmark" review, commissioned by the WHO and published in The Lancet in 2019. The analysis of population epidemiological studies and feeding studies said that dietary fibre in "good" carbohydrates will cut people's chances of early death from a wide range of diseases including cardiovascular disease (heart disease), coronary heart disease, stroke, type 2 diabetes, colorectal cancer, breast cancer, reduction in body weight and cholesterol—increasing satiety and helping weight control and favourably influencing lipid and glucose levels.[11] The report made examples of "good" carbohydrates being whole grain bread and oats, wholegrain cereals, pasta and bread, nuts and pulses[11] and declared sugar a "bad" carbohydrate.[11]
