About this study

The study aims to investigate the effects of optimized plant protein mixtures versus their animal protein equivalents on satiety, protein metabolism, and overall metabolic health

Read the detailed description

The research described in this application is crucial as it addresses a fundamental issue - the nutrition quality of plant-based diets. Plant-based diets are widely acknowledged for their health benefits as they are known to reduce disease risks and all-cause mortality. However, concerns about plant protein quality arise due to disparities in amino acid profiles, particularly their essential amino acid adequacy, which remains a challenge in adopting a plant-based protein diet as part of a healthy diet. Other challenges include low palatability, poor texture, flavor, and mouthfeel. To address this, the Singapore Institute of Food and Biotechnology Innovation (SIFBI) has developed Asian-centric plant-based food products by combining multiple plant-protein sources to emulate the amino acid profile of animal proteins. This approach aims to optimize plant-based diets by ensuring enhanced protein quantity and quality in a mixed meal, not only to encourage adaptation of plant based protein into daily meals for environmental sustainability but also with the long-term objectives to use diet as a means to improve metabolic health in the Asian demographics. This human study is designed to explore the effects of consuming optimized plant-protein-based products compared to conventional animal protein- based products on postprandial metabolism and overall metabolic health. The study is structured around several specific objectives:

  1. Evaluate Nutritional Impact: The study aims to assess the nutritional efficacy of the investigational food products. This will involve measuring circulating amino acids and protein metabolism markers, such as blood urea and amino acid metabolites. Additionally, the study will examine the effects of these foods on overall metabolic health, including their impact on glycaemic response and inflammatory markers.
  2. Investigate Postprandial Satiety: Another key aim is to explore the effects of investigational food items on postprandial appetite and satiety. This will help determine how these foods influence hunger and fullness sensations following consumption, which is crucial for understanding their potential role in weight management and metabolic regulation.
  3. Investigate Consumer Acceptance: The study will also assess consumer acceptance of the investigational food products to identify the potential barriers. This includes evaluating the palatability of these products, as their taste, texture, and overall appeal are vital factors in determining their potential integration into regular diets.
  4. Gain Mechanistic Insight: The study seeks to gain deeper mechanistic insights by systematically investigating changes in the postprandial circulating proteome. This analysis will enhance our understanding of the biological processes and pathways involved in the body's response to these food products post-consumption.
