In clinical trials, food can be thought of as another form of investigational product. Tight control over diet and dietary parameters, including meal composition is critical.
Nutritional Assessments Techniques Commonly Utilized:
- Appetite and food intake studies (ad libitum buffet meals, “free living” ad libitum eating conditions)
- Assessment of hunger, satiation, satiety, and motivation to eat (VAS and other validated questionnaires)
- Standardized meals for glucose assessments, specific energy balance, and macronutrient requirements
- Food diaries and nutrition counseling
