Not Applicable

Completed

• Conditions: Thirst
• Interventions: Behavioral: Effect of ingestion sugary and sweetened drinks on thirst

• Registration Number: NCT01502722
• Lead Sponsor: Universidade do Porto

Brief Summary

The purpose of this study is to determine if regular soft drinks (with sugar) have the same effect on thirst as diet soft drinks(with sweeteners).

Detailed Description

Participants should be in the laboratory at 8.00 in order to collect the values of weight, height, total body water, intracellular water and extracellular water in a Segmental Multi Frequency Body Composition Monitor (TANITA MC 180 MA®). Then, a blood sample will be collected for analysis of blood glucose and osmolality. They will sit at individual tables for the duration of the session and were allowed to read, listen to music with earphones, or use their portable computers with the exception of internet access to minimize visual cues (e.g., unwanted publicity for beverages or visiting Web sites showing pictures of food and drinks), which may have effect on thirst. Breakfast will be served at 9.30 on every occasion and preload stimuli will be offered exactly 60 minutes after breakfast (at 10.30). Lunch will be provided at 13.00. Motivational ratings will be first obtained at the end of collection of blood sample (baseline or time 0) and every 30 minutes thereafter until the lunch time (times 1 through 7). After lunch (time 8), participants will complete the last set of ratings and will bring a food diary to record all food and fluid intake until 00.00 that day.

Arm && Interventions

Group	Intervention	Description
Group 1 - Crossover	Effect of ingestion sugary and sweetened drinks on thirst	This group will drink water in the 1st study.
Group 2 - Crossover	Effect of ingestion sugary and sweetened drinks on thirst	This group will drink Pineapple Soda in the 1st study
Group 3 - Crossover	Effect of ingestion sugary and sweetened drinks on thirst	This group will drink Pineapple Diet Soda in the 3rd study

Primary Outcome Measures

Name	Time	Method
Motivational Ratings	1 day	Participants will rate their hunger, thirst, nausea, mouth dryness, desire to eat, desire to drink using nine point category scales. The unipolar adjective scales were anchored at each end with labels: 1 = not at all and 9 = extremely. Participants also rated their liking for the beverage along nine point hedonic preference scales where 1 = dislike extremely and 9 = like extremely

Secondary Outcome Measures

Name	Time	Method
Food Behavior After Intervention	1 day	After lunch, participants will bring a food diary to record all food and fluid intake until 00.00 that day. Then, we will analyse total calories ingested, total fluid ingested and the volume of sugar and sugary beverages ingested.
Amount of water ingested	1 day	After the ingestion of 3 preloads with the beverages in study (water, pineapple soda and pineapple diet soda), the participants will lunch the same meal bu the water ingestion will be ad libitum.
