Dietary Polyphenols in Non‐Communicable Chronic Diseases: Neuro–Enteric Mechanisms, Multi‐Omics Biomarkers and Translational Opportunities

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
This illustration highlights how dietary polyphenols from foods like berries, grapes, and green tea travel through the gut, where microbiota transform them into bioactive metabolites. These metabolites pass into the bloodstream, strengthen the gut barrier, and ultimately reach the brain, supporting neuroprotection through antioxidative and anti ...

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...
