Article Abstract
Background/objectives: This study aimed to examine the association between ultra-processed food (UPF) consumption and obesity in Korean adults.
Methods: Data from the 2019 to 2021 Korea National Health and Nutrition Examination Survey were analyzed. Dietary intake and UPF consumption were assessed using the NOVA food classification based on 24 h recall data from 9662 participants (aged 19-64 years). The participants were divided into three groups based on the tertile of UPF intake. Obesity was defined as a body mass index of ≥25 kg/m. Multivariable logistic regression was used to estimate the adjusted odds ratios (AORs) with 95% confidence intervals (CIs) after controlling for potential confounders.
Results: Of the participants, 50.2% were men and 49.8% were women. Men consumed more UPFs daily (401.3 g) than women (260.1 g; < 0.0001). Among the various categories of ultra-processed foods, 'soft drinks, fruit and vegetable drinks' were the most frequently consumed by both men and women, with men showing a notably higher intake than women. Compared to the lowest quartile of UPF intake, the highest tertile was significantly associated with obesity in men (AOR: 1.28; 95% CI: 1.05-1.55; for trend = 0.0003).
Conclusions: This study suggests that a high intake of UPFs is associated with increased odds of obesity in men. Further research is needed to elucidate the specific negative health effects of UPFs in different populations, and targeted efforts should promote healthy diets for both men and women.

Thymol is a major monoterpene compound from plants. Thymol exhibits antifungal, antioxidant, and anti-inflammatory properties. Over the past few years, extensive research has underscored the pivotal role of thymol in delaying postharvest senescence in fruits and vegetables, suppressing fungal growth in meat products, and enhancing the shelf life of meat and processed foods.

Summary: Cell-type deconvolution is widely applied to gene expression and DNA methylation data, but access to methods for the latter remains limited. We introduce , a new R package that simplifies access to DNA methylation-based deconvolution methods predominantly for blood data, and we additionally compare their estimates to those from gene expression and experimental ground truth data using a unique matched blood dataset.

Extensive epidemiological research and the findings from one randomised controlled feeding trial (RCT) have shown associations between the consumption of ultra-processed foods (UPFs) and higher energy intakes. To date the specific properties of UPF foods and diets that may be responsible for driving higher energy intakes remain unclear. A comparison of the diets in the single RCT to date showed a significantly higher eating rate (g/min, ER) for meals in the UPF diet compared to those in the minimally processed diet.

It is unknown how human health is affected by the current increased consumption of ultra-processed plant-based meat analogues (PBMA). In the present study, rats were fed an experimental diet based on pork or a commercial PBMA, matched for protein, fat, and carbohydrate content for three weeks. Rats on the PBMA diet exhibited metabolic changes indicative of lower protein digestibility and/or dietary amino acid imbalance, alongside increased mesenteric (+38%) and retroperitoneal (+20%) fat depositions despite lower food and energy intake.

The melting characteristics of cheese play a pivotal role in determining functional performance in various applications. Measuring the meltability and melting point of cheese is a challenge and requires sophisticated equipment, a laboratory setup, and personnel training, and the cost can be prohibitive. Over the years, many tests have been developed to determine the meltability or melting point of cheese.
