Measurement of Acute Metabolite Changes Following Consumption of Unprocessed and Processed Microalgae: A Randomized Crossover Trial
Protein consumption is essential for various physiological processes, with microalgae and plant proteins gaining increasing attention due to their health benefits.
To better understand how different protein types and processing methods impact health outcomes, this study aims to analyse the metabolite changes in response to different protein sources.

详细说明
This study is a randomised crossover trial involving 16 participants.
It comprises one screening visit and five test visits, during which participants will consume intervention drinks containing primarily (1) maltodextrin, (2) whey protein isolate, (3) soy protein isolate, (4) bead-milled microalgae, or (5) non-bead-milled microalgae in a randomised order.
The study aims to investigate and compare acute postprandial metabolite responses following the consumption of bead-milled and non-bead-milled microalgae, as well as whey and soy protein isolates, in Singaporean adults.

Appetite
大体时间:Baseline, 60, 120, 180, 240, 300 minutes

The Appetite Visual Analogue Scale (VAS) questionnaire will be administered, with participants rating five appetite-related outcomes, i.e. desire to eat, hunger, fullness, satisfaction, and prospective food consumption.
Each response will be measured on a 100-mm visual analogue scale and scored from 0 to 100, with higher scores indicate a greater intensity of the outcomes being assessed, i.e. greater desire to eat, greater hunger, greater fullness, greater satisfaction, or a greater perceived amount of food that could be consumed.
