More than half of the world's population uses rice as a source of carbon intake every day. Improving grain quality is thus essential to rice consumers. The three main properties that determine rice eating and cooking quality--amylose content, gel consistency, and gelatinization temperature--correlate with one another, but the underlying mechanism of these properties remains unclear. Through an association analysis approach, we found that genes related to starch synthesis cooperate with each other to form a fine regulating network that controls the eating and cooking quality and defines the correlation among these three properties. Genetic transformation results verified the association findings and also suggested the possibility of developing elite cultivars through modification with selected major and/or minor starch synthesis-related genes.

Background: While some children are open to trying new foods, many exhibit dislike or refusal when encountering them for the first time. These behaviors can be broadly characterized as food neophobia and pickiness, which are believed to be the primary forms of food rejection among children. Because there are differences between countries in early feeding practices and culinary traditions, culturally adapted scales are needed to measure these behaviors.

Risk Factors Analysis and Predictive Model Construction for Autoimmune Gastritis: A Nationwide Multicenter Case-Control Study in China.

J Gastroenterol Hepatol

March 2025

Division of Gastroenterology and Hepatology, NHC Key Laboratory of Digestive Diseases, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Objective: Here, we ascertained the clinical characteristics of Chinese patients with autoimmune gastritis (AIG) and determined the correlation of dietary and lifestyle factors with AIG occurrence and development to establish a noninvasive predictive model for AIG.

Methods: In this case-control study, we enrolled 479 patients from seven independent centers nationwide in China; of them, 279 had AIG, 112 had chronic atrophic gastritis mostly in the antrum, and 88 had chronic nonatrophic gastritis. Their clinical and lifestyle data were systematically collected and analyzed.

We performed GWAS for starch properties and eating, cooking and appearance quality characteristics traits in rice and then used PLS regression to show importance of different loci for different food applications. We performed a genome-wide association study for appearance, eating and cooking quality traits in grain of japonica rice cultivars and identified candidate genes for adhesiveness of cooked rice grains, amylopectin composition and β-glucanase activity in rice endosperm among a total of 525 quantitative trait nucleotide (QTN) loci. The study used 1,054,635 single-nucleotide polymorphisms (SNPs) based on genome sequence data of 150 rice cultivars and 89 grain appearance, eating and cooking quality traits.

The Effect of Anxiety and Nutritional Habits on the Body Distortion of Athletes.

Nutrients

February 2025

Faculty of Medicine, Health and Sports, Universidad Europea de Madrid, Villaviciosa de Odón, 28670 Madrid, Spain.

Anxiety disorders have been rising globally, particularly among adolescents and women. However, the relationship between diet, psychological traits, and anxiety levels in athletes remains underexplored. This study aimed to analyze the nutritional and psychological differences between athletes with varying anxiety levels, hypothesizing that higher anxiety correlates with unhealthier dietary habits, greater body distortion, and less adaptive psychological profiles.

Influence of Mediterranean Diet and Incidence of Global Warming on Food Habits and Plant Growth in Northern Mediterranean Latitudes: Narrative Review.

Nutrients

February 2025

Mediterranean Diet and Health Association (NMS), INSERM (Institut National de la Santé et de la Recherche Médicale), Laboratory Bio-PeroxIL, University of Burgundy Europe, 21000 Dijon, France.

Background: Climate change has consequences for farming, food diversity and availability, and diet habits. There is now evidence that the Mediterranean climate is rapidly spreading to the Northern European latitudes.

Objective: This narrative review aims to identify relevant studies related to climate change that could favor the progression of the Mediterranean climate in the northern latitudes of Europe, mainly in France, and to predict what the consequences of these changes on the human diet could be, especially using the concept of the Mediterranean diet, with subsequent impacts on health, farming, and eating habits.
