Judy buttriss update

Professor Judith Buttriss BSc DipDiet PhD RNutr FAfN

 Director General

 Judy studied Nutrition and Dietetics at the University of Surrey. She worked as a research dietitian in Professor John  Waterlow’s obesity unit for about a year before returning to Surrey to study for a PhD concerning vitamin C and  hepatic drug metabolism, which combined the disciplines of nutrition, biochemistry and toxicology. Equipped with a  doctorate, Judy worked in various labs as a postdoc researcher, in particular on vitamin E and selenium at Guy’s  Hospital Medical School. In 1985 she decided to leave the lab environment and joined the National Dairy Council  (NDC) as Senior Nutritionist, where she stayed until 1998 when she joined the BNF as Science Director. She became  the BNF’s Director General in October 2007.

 “I decided at the age of 14 or 15 that I wanted to study nutrition, my ambition then was to work in a hospital as a  dietitian. During my industrial year at university I had the opportunity to work at the Institute of Child Health for 6  months on a research project and this made me realize that I wanted to help build and define the nutrition science  evidence base, and a PhD was the route I took, followed by several postdoc contracts. At this point in my career I was  looking for a permanent academic post when a job came up at the NDC. It was a huge change at the time but one  that set the stage for my career in public health nutrition – building on the skills learned as a dietitian and focused on the communication and dissemination of evidence-based nutrition information. But I have not lost my hunger for learning new things, trying to look at the information before me with fresh eyes and keeping an open mind, whilst ensuring that scientific evidence underpins my efforts. Working at the BNF is full of challenges and opportunities – no two days are ever the same and I wouldn’t want it any other way.”
