The Nutritional Sciences department of Profil, headed by Dr Martina Heer, designs and performs studies with day-by-day highly standardised, constant nutrient intake (metabolic balance studies). This helps to reduce variability e.g. in postprandial blood glucose, thereby minimising sample sizes. Investigations of drug and food effects on metabolism also benefit from standardized nutrient intake since any nutritional impact on study outcome parameters can be excluded. This is of particular importance when providing scientific evidence for potential health claims of new food products.
The metabolic balance studies will be supported by additional methods for the assessment of body composition using air displacement phlethysmography and/or determination of energy expenditure through indirect calorimetry.
