My key interest is in human nutrition and food chain nutrition in particular. This involves understanding the pre-consumption factors which affect food composition and functionality and the subsequent effects on human health. A particular focus is animal-derived foods, their effect on cardiometabolic disease (CMD) risk and how the composition of animal-derived foods can be improved to reduce risk.

My current work covers milk and dairy products and the fats they contain in relation to CMD risk including the use of both meta-analysis of data from prospective studies and more detailed work into the mechanisms involved. Current work also includes the effects of milk proteins on blood pressure and vascular stiffness as well as their effect on insulin stimulation and sensitivity, key factors in relation to type 2 diabetes, factors affecting the iodine content of milk and the role of animal-derived foods as sources of dietary vitamin D. Other research includes studies on the A1 and A2 β-casein proteins in milk and the specific effect a peptide from the A1 protein may have on inflammation in the gut.
