Dr Marie-Ann Ha is a registered Public Health Nutritionist. She has two main research interests; carbohydrate nutrition and chemistry, and ensuring we have healthy, sustainable food supply chains.
Marie-Ann is a Director of East Anglia Food Link, a not for profit group that is working closely with small to medium sized farms in the East of England, to develop a sustainable food supply system within the region.
Marie-Ann was on secondment to the secretariat of the Scientific Advisory Committee on Nutrition at Public Health England to help write the Carbohydrates and Health Report having worked extensively in the past on the structure of plant cell walls and how this relates to dietary fibre intake.
