Nutritional characterization of Cusco green tea and its synergistic effect with omega‐3 on metabolic and cognitive dysfunctions in obese rats

Journal of the Science of Food and Agriculture, Volume 106, Issue 9, Page 5643-5657, July 2026.
Abstract BACKGROUND Obesity and its metabolic complications, such as insulin resistance and cognitive decline, remain a global health challenge. Green tea (Camelia sinensis) and ω‐3 polyunsaturated fatty acids (PUFAs) are recognized for their antioxidant, anti‐inflammatory, and neuroprotective properties.

Targeted metabolomics reveals the optimal harvest time of Cabernet Sauvignon grapes in an emerging high‐altitude tropical region

Journal of the Science of Food and Agriculture, Volume 106, Issue 9, Page 5614-5628, July 2026.
Abstract BACKGROUND Climate change has driven the expansion of viticulture in high‐altitude tropical regions. The dynamics of grape ripening and its metabolic profile are influenced by climatic conditions. This study aimed to identify the optimal harvest period for Cabernet Sauvignon grapes cultivated in an emerging Brazilian high‐altitude region using

Epicatechin and its in vivo metabolite, 3 '-O-methyl epicatechin, protect human fibroblasts from oxidative-stress-induced cell death involving caspase-3 activation

, 2001
There is considerable current interest in the cytoprotective effects of natural antioxidants against oxidative stress. In particular, epicatechin, a major member of the flavanol family of polyphenols with powerful antioxidant properties in vitro, has ...

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...
