The objective of the study is to evaluate palatability (primary objective) and perceived satiating effects (secondary objective) of two Oral Nutrition Supplements (ONS) prototypes and six commercially available ONS products. The products are matched on calorie content per portion.
The study is a single-blind intervention with a within-subjects design. In total 104 apparently healthy and independently living older adults aged 65 will be recruited to participate. Participants will visit the research facilities eight times in a period of one month. On each test-day participants will consume and evaluate a single product.
