Besides their nutritional role, proteins are recognized for their ability to regulate both short- and long-term energy homeostasis. However, studies investigating the effects of proteins based on their quality and origin remain limited and often lack comparability. Nonetheless, existing research consistently underscores the influence of proteins on food intake regulation.

Article Synopsis
  • - Chicory is being researched as a functional food, and this study examines how gastrointestinal digestion affects its composition and bioactive properties by creating an aqueous decoction from chicory flour.
  • - The study utilized a metabolomic approach to observe how digestion changes specific bioactive molecules across different stages (oral, gastric, and intestinal) and evaluated antioxidant, anti-inflammatory, and hormone regulation effects before and after digestion.
  • - Results showed that digestion alters chlorogenic acid and sesquiterpene lactones, enhancing chicory's antioxidant and anti-inflammatory effects, with a notable increase in reactive oxygen species (ROS) scavenging capacity and metabolite activity post-digestion.

In response to nutrients, intestinal L- and K-cells naturally secrete glucagon-like peptide 1 (GLP-1). GLP-1 regulates postprandial blood glucose by increasing insulin secretion, slowing down gastric emptying and inducing satiety. A selection of specifically developed collagen hydrolysates was screened for their ability to enhance natural GLP-1 production in vitro.
