Brief Summary

The liking of a breakfast meal has been shown to influence food choice throughout the day. This study will investigate the effects that liking of different coffee beverages has on daily food intake.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a postprandial acute meal crossover blinded study in which 30 fasted young healthy women will consume one of 3 butter-rich coffees, in random order, at each of three study sessions separated by at least 4 days. Participants will rate the coffee characteristics and complete paper visual analogue scale ratings of alertness, fatigue, nausea, satiety, and comfort for 180 minutes and consume a pasta lunch meal.
