Assessing quality and polyphenol in vitro bioaccessibility in healthy jelly gummies with microencapsulated and non-encapsulated pomegranate peel extract.

Background: Pomegranate peel extract (PPE) is rich in polyphenols, notably punicalagin and ellagic acid, but is sensitive to environmental degradation and has low bioavailability. Microencapsulation can enhance PPE stability and bioaccessibility, making it suitable for functional foods like jelly gummies (JG). JG containing microencapsulated PPE (MPPE) have not been studied.

Guidance and position of RINN22 regarding precision nutrition and nutriomics.

Background: Precision nutrition is based on the integration of individual´s phenotypical and biological characteristics including genetic variants, epigenetic marks, gut microbiota profiles and metabolites fingerprints as well as medical history, lifestyle practices, and environmental and cultural factors. Thus, nutriomics areas including Nutrigenomics, Nutrigenetics, Nutriepigenetics, Nutrimetabolomics, and Nutrimetagenomics have emerged to comprehensively understand the complex interactions between nutrients, diet, and the human body's molecular processes through precision nutrition.

Summary: This document from the Ibero-American Network of Nutriomics and Precision Nutrition (RINN22; https://rinn22.

Sirtuin Expression in Insulin-Sensitive Tissues of Rats with Impaired Glucose Tolerance is not Affected by Resistance Training or Zinc Supplementation.

While physical activity and zinc supplementation have shown benefits in diabetes management, little is known about their effect on less severe glucose homeostasis disorders, such as impaired glucose tolerance. On the other hand, sirtuins have an important role in glucose metabolism and insulin sensitivity, but to date, there is no information about the impact of zinc supplementation or physical activity on their regulation in individuals with impaired glucose homeostasis. The aim of this study was to assess the effect of supplemental zinc, muscle-resistance training, and their combination on the expression of selected sirtuins in insulin-sensitive tissues of rats with impaired glucose tolerance.

Dataset on sub-daily vertical profiles of physicochemical parameters and chlorophyll concentration in El Val reservoir, together with its daily meteorological data, storage state and downstream flow (2018-2022).

The dataset addressed in this article contains parameters about El Val reservoir (province of Zaragoza, Spain). It includes physicochemical variables, the water level, the stored water volume, its meteorological conditions and the flow rate of its effluent, the Queiles River, a few metres downstream of the dam. The El Val reservoir stores water from the Val River, but it also receives water from the Queiles River through a pipeline and from several ravines.

Acute Administration of Calafate (Berberis microphylla) Extract Induces the Expression of Thermogenic Markers and Modulates Gut Microbiota in Mice Fed a High-Fat Chow Diet.

Introduction: Obesity, characterized by excess adipose tissue, is a major public health problem worldwide. Brown adipose tissue (BAT) and beige adipose tissue participate in thermogenesis through uncoupling protein 1 (UCP1). Polyphenols including those from Calafate (a native polyphenol-rich Patagonian berry), are considered as potential anti-obesity compounds due to their pro-thermogenic characteristics.
