Repeated Sweet Consumption and Subsequent Sweet Food Preferences and Intake

Study Overview
=================
Brief Summary
-----------------
This study will assess the impact of repeated sweet versus non-sweet food consumption on subsequent sweet and non-sweet food preferences and intakes

Detailed Description
-----------------
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.

| Experimental: Increase sweet food consumption<br>Participants are asked to increase their consumption of sweet foods throughout their diet. Participants will be supported through an individual dietary interview where sweet foods will be highlighted and additional sweet food consumption recommended. | Behavioral: Sweet food consumption<br>* Comparison of the impacts of sweet and non-sweet food consumption<br>|
