Nutrition: How micronutrients modify digestive function

Project Details

Additives from natural sources (micronutrients) are included in feed to accelerate animal rates of maturation and to increase muscle mass. Athletes also modify their diets to change body composition. We have novel data that show that receptors for micronutrients are expressed on hormone secreting cells in the gut. The hormones influence feeding behaviour, nutrient breakdown and nutrient absorption. In this project you will work with a team of researchers to identify receptors for micronutrients and to unravel their mechanisms of action.
