Rachel Brown is the Deputy Head of Department. She is a graduate of the University of Otago with a BSc, MSc and PhD (1999). Rachel’s research interests lie in the areas of nuts and health, energy metabolism, sports nutrition, and lipid metabolism. Recently she has been involved in research investigating the effects of nut consumption on plasma lipids and lipoproteins, inflammation and endothelial function. This research also investigated whether public health advice regarding nut consumption for the reduction in cardiovascular disease risk is sustainable and achievable. She is also currently involved in a research project investigating potential differences in individuals who report difficulties in losing weight (conservers) compared to individuals who report difficulties in gaining weight (expenders).

Rachel is a member of the Agencies for Action Scientific committee where she has co-authored several reports including “Does the family environment contribute to food habits or behaviours and physical activity in children?”; “Does sedentary behaviour contribute to chronic disease or chronic disease risk in adults?”; and “Are nutrition and physical activity primary prevention interventions in the primary care setting effective at reducing biochemical and physical risk factors?”

Rachel coordinates the following papers:

HUNT451: Nutritional Assessment
HUNT452: Nutrition and Human Health

She also teaches in the following papers:

HUNT221: Obesity
HUNT232: High fat diets
HUNT233: Obesity

HEAL192: Obesity
DENT262: Dietary assessment, obesity, heart disease
