Effects of Bisphenol A on the Risk of Developing Obesity.

Background: Every year the global incidence of obesity increases considerably and among the factors that favor it is bisphenol A (BPA), an endocrine disruptor widely used in plastics and omnipresent in many everyday objects.

Methods: A total of 19 studies published between 2018 and 2023 that addressed the relationship between BPA exposure and obesity were included in this review in order to better understand its behavior and mechanisms of action.

Results: The studies reviewed conclude that BPA is an obesogen that alters the function of hormonal receptors, promotes metabolic syndrome, affects certain genes, etc.

[Dietary patterns and factors and their association with the anxiety in adult population: proposed recommendations based on a scoping review of systematic reviews and meta-analyses].

A high percentage of the population suffers from anxiety, a disorder that can be influenced by dietary habits. The aim of this review was to compile the existing evidence on dietary patterns and factors, and their association with anxiety to propose clinically applicable recommendations. A scoping review of systematic reviews and meta-analyses was conducted in the MEDLINE database (PubMed) until January 2021, reporting the main findings based on PRISMA (2020).

Properties and Biodegradability of Films Based on Cellulose and Cellulose Nanocrystals from Corn Cob in Mixture with Chitosan.

The increase in consumer demand for more sustainable packaging materials represents an opportunity for biopolymers utilization as an alternative to reduce the environmental impact of plastics. Cellulose (C) and chitosan (CH) are attractive biopolymers for film production due to their high abundance, biodegradability and low toxicity. The objective of this work was to incorporate cellulose nanocrystals (NC) and C extracted from corn cobs in films added with chitosan and to evaluate their properties and biodegradability.
