Consumer-driven characterization of healing foods using Q methodology and Q based sorting
With the global surge in interest in healing following the COVID-19 pandemic, there has been a growing interest in the concept of healing within the context of food. However, a clear understanding of how consumers perceive and define healing food is lacking. This study aimed to investigate consumer perceptions of healing food and the underlying […]
The effects of in vitro vitamin D treatment on glycolytic reprograming of bone marrow-derived dendritic cells from Ldlr knock-out mouse
Activated dendritic cells (DCs) undergo significant metabolic reprogramming, which is characterized by an increase in aerobic glycolysis and a concurrent progressive loss of oxidative phosphorylation. The modulation of metabolic reprogramming is believed to be closely related to the function of DCs. Vitamin D has been reported to inhibit the maturation of DCs. DC dysfunction has been reported in diabetic patients, […]
Synergistic efficacy of ultrasound and ammonium persulfate in inactivating Escherichia coli O157: H7 in buffered peptone water and orange juice
This study investigated the synergistic effects of ammonium persulfate (PS) and ultrasound (US) on the inactivation of Escherichia coli O157:H7 in buffered peptone water (BPW) and orange juice products. A comprehensive assessment of PS concentrations ranging from 1 to 300 mM, considering not only the statistical significance but also the reliability and stability of the experimental outcomes, showed […]
Dietary vitamin D3 supplementation enhances splenic NK cell activity in healthy and diabetic male mice
Type 2 diabetes mellitus negatively affects the immune system, resulting in reduced natural killer (NK) cell activity. Vitamin D has been shown to regulate innate and adaptive immune cells. However, the effects of vitamin D on NK cells remain inconclusive, especially in the context of diabetes. We hypothesized that dietary vitamin D 3 supplementation can enhance NK […]
Changes in the choice motive and emotional perception of chocolates in response to stress
Although chocolates are often chosen for sensory pleasure, they are also selected to enhance mood and relieve emotional stress, or potentially chosen for its perceived health benefits if stress adversely affects physical well-being. This study aimed to investigate whether emotional stress influenced the motivations behind chocolate selection, subsequent liking, and emotional response. Participants were divided […]
Screening for bacterial genotoxicity and cytotoxicity of the commercial color additives Monascus red and Curcuma longa Linne extract
In a previous study that evaluated the genotoxicity of natural color additives, Monascus red and Curcuma longa Linne extracts showed potential genotoxicity and cytotoxicity (Do and Kwon, 2022). To determine whether these results were batch-specific or inherent to these additives, bacterial reverse mutation and in vitro cytotoxicity tests were conducted on all market-available products. Monascus […]
Gastric and colorectal cancer incidence attributable to dietary factors in Korea
Dietary factors play a role in the etiology of gastrointestinal cancer. We aimed to estimate the burden of gastric and colorectal cancer that can be attributable to dietary factors in adults aged 20 years and older in Korea in 2018. Dietary intakes in 2000 were estimated using data from the 2001, 2005, and 2007–2018 Korea National […]
Intake of energy and macronutrients according to household income among elementary, middle, and high school students before and during the COVID-19 pandemic: a cross-sectional study
This study examined the intake of energy and macronutrients among elementary, middle, and high school students according to household income before the COVID-19 pandemic (2016–2019), during the social distancing period (2020–2021), and after the social distancing measures were lifted (2022). We included 5,217 students aged 5–18 from the Korea National Health and Nutrition Examination Survey (KNHANES) […]
Taste receptor type 1 member 3 regulates Western diet-induced male infertility
Western diet (WD), characterized by a high intake of fats and sugary drinks, is a risk factor for male reproductive impairment. However, the molecular mechanisms underlying this remain unclear. Taste receptor type 1 member 3 (TAS1R3), activated by ligands of WD, is highly expressed in extra-oral tissues, particularly in the testes. Here, we investigated to determine the effects of WD intake […]
Exploring the association between dietary patterns and the types of dietary supplements used
This study explored the relationship among dietary patterns, dietary supplement use, and supplement types. An online survey encompassing 1,018 participants was conducted. Logistic regression analysis was used to examine the relationship between dietary patterns, dietary supplement use, and the types of supplements. The results indicated that the use of vitamin C, calcium, and reishi shell-broken […]
