AI Article Synopsis
- Adopting plant-based diets rich in fiber could help reduce global warming and obesity rates, but the reasons why people choose these diets are not fully understood.
- A study involving over 16,000 adults assessed satiety and mood before and after eating either plant-based or animal-based meals, finding that both types of meals increased satiety and mood after eating.
- While plant-based meals did show slightly higher pre-meal mood, the differences in post-meal hunger and mood changes between meal types were not significant, with factors like protein content and individual preferences having a more considerable influence.
Article Abstract
Adopting plant-based diets high in fiber may reduce global warming and obesity prevalence. Physiological and psychological determinants of plant-based food intake remain unclear. As fiber has been linked with improved gut-brain signaling, we hypothesized that a single plant-based (vegetarian and vegan) compared to an animal-based (animal flesh) meal, would induce higher satiety, higher mood and less stress. In three large-scale smartphone-based studies, adults (n = 16,379) ranked satiety and mood before and after meal intake. Meal intake induced satiety and higher mood. Plant-based meal choices did not explain differences in post-meal hunger. Individuals choosing a plant-based meal reported slightly higher mood before and smaller mood increases after the meal compared to those choosing animal-based meals. Protein content marginally mediated post-meal satiety, while gender and taste ratings had a strong effect on satiety and mood in general. We could not detect the profound effects of plant-based vs. animal-based meals on satiety and mood.

The relationship between cannabis and cardiovascular disease: clearing the haze.
Nat Rev Cardiol

Stanford Cardiovascular Institute, Stanford, CA, USA.
Cannabis has been consumed for centuries, but global regulatory changes over the past three decades have increased the availability and consumption of cannabis. Cannabinoids are touted to have therapeutic potential for many diseases and could be a replacement for opioids for analgesia and sedation. However, cannabinoids can cause substantial adverse cardiovascular events that would mitigate any potential benefit.

Patient Centered Solutions, IQVIA, Reading, UK.
Background: Despite approvals of new first-line immunotherapies for advanced/metastatic gastric cancer/gastroesophageal junction cancer (aGC/GEJC), patients' median survival is around 14 months and their health-related quality of life (HRQoL) is affected by disease-related symptoms and treatment-related side effects. Using a targeted literature review (TLR) and patient interviews, this study identified disease- and treatment-related concepts that are important to patients with aGC/GEJC and their HRQoL.
Methods: A TLR was conducted to identify primary qualitative studies from 2018 to 2021 on patients' experiences with aGC/GEJC.
Foaming purees as a strategy to modify oral processing time.
Curr Res Food Sci

Institute of Agrochemistry and Food Technology (IATA, CSIC), Spain.
Food structure modification by increasing viscosity or adding heterogeneity to the food product has shown to effectively change food oral processing. In this study, it was hypothesized that the addition of gas to purees could affect oral processing. This was achieved by creating different structures in purees using a gas syphon, vacuum and syphon + vacuum.

Caregivers' feeding practices shape their child's eating patterns and subsequent health. Research shows that sensitive feeding is linked to healthy development and self-regulation but depends on caregiver responsiveness to infant needs and appetite cues. Responsive feeding (RF) is influenced both by characteristics of the caregiver and expressiveness of the infant.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.
