简要总结
This study will assess the impact of repeated sweet versus non-sweet food consumption on subsequent sweet and non-sweet food preferences and intakes
详细描述
Participants will be randomized to receive instructions to either increase or decrease sweet food consumption for 6 days, and impacts on food preferences and intakes will be assessed at baseline and after 1 week. Preferences for sweet and non-sweet foods will be assessed during two taste tests at each assessment time, where six different foods will be rated. Sweet and non-sweet food consumption will also be measured at two meals at each assessment time - breakfast and lunch. Identical buffet meals composed of sweet and non-sweet foods suitable for consumption at breakfast and lunch will be provided ad-libitum.

结局指标
主要结局
Food Preferences
时间窗: Change from Baseline to 1 week
Ratings of three sweet and three non-sweet foods during a taste test (two tests). Measures are made on a visual analogue scale from 0 (not at all) to 100 (extremely), where higher scores denote higher preferences.
Food Intake
时间窗: Change from Baseline to 1 week
Amount of sweet and non-sweet foods consumed during breakfast and lunch. Measures are made of grams of each sweet food consumed.
