Associations of dietary patterns with obesity and weight change for adults aged 18–65 years: Evidence from the China Health and Nutrition Survey (CHNS)

Background: Obesity has become a significant public health problem within China. By observing dietary patterns, an individual's actual dietary habit of nutrients or foods in combination can be identified. We aimed to examine dietary patterns in relation to the risk of obesity (body mass index (BMI) ≥ 25 kg/m<sup>2</sup>) and weight change (average weight change […]

Predicted pro-inflammatory hs-CRP score and non-alcoholic fatty liver disease

Background: Non-alcoholic fatty liver disease (NAFLD) is a major contributor to liver diseases globally, yet there are limited studies investigating the impact of diet and lifestyle factors on its development. This study aimed to examine the association between the prevalence of NAFLD and predicted pro-inflammatory high-sensitivity C-reactive protein (hs-CRP) score. Methods: We included 1,076 Korean […]

코로나19 팬데믹 기간의 1인 가구 식생활 변화

This study aimed to investigate the dietary changes among adults living alone during the COVID-19 pandemic in the Republic of Korea. An online survey was conducted to examine dietary changes before (in 2019) and during (in 2021) the pandemic. The data from 337 adults living alone who responded to the survey were used for analysis. […]

Korean consumers’ use and concerns about food delivery service

Abstract BACKGROUND/OBJECTIVES Despite the rapid growth of the online food delivery service market since the outbreak of coronavirus disease 2019, little research has focused on how consumers are using food delivery service and what they are concerned about when using food delivery service. Moreover, previous studies have not paid adequate attention to how these concerns […]

Dietary supplement use and its related factors among Chinese international and Korean college students in South Korea

Abstract BACKGROUND/OBJECTIVES The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. SUBJECTS/METHODS We conducted online surveys of 400 Chinese international students and 452 Korean college students […]

Taste receptor type 1 member 3 mediates diet-induced cognitive impairment in mice

Aims: Long-term consumption of a western diet (WD), which is characterized by high intake of saturated fats and sugary drinks, causes cognitive impairment. However, the molecular mechanism by which WD induces cognitive impairment remains unclear. Taste receptor type 1 member 3 (TAS1R3), activated by ligands of WD, is expressed in extra-oral tissues, including the brain, […]

Taste receptor type 1 member 3 enables western diet-induced anxiety in mice

Background: Accumulating evidence supports that the Western diet (WD), a diet high in saturated fat and sugary drinks, contributes to the pathogenesis of anxiety disorders, which are the most prevalent mental disorders worldwide. However, the underlying mechanisms by which WD causes anxiety remain unclear. Abundant expression of taste receptor type 1 member 3 (TAS1R3) has […]

Gut taste receptor type 1 member 3 is an intrinsic regulator of Western diet-induced intestinal inflammation

Background: Long-term intake of a Western diet (WD), characterized by a high-fat content and sugary drinks, is hypothesized to contribute to the development of inflammatory bowel disease (IBD). Despite the identified clinical association, the molecular mechanisms by which dietary changes contribute to IBD development remain unknown. Therefore, we examined the influence of long-term intake of […]

Increased cholesterol uptake is associated with the altered gene expression in white adipose tissue of ApoE-/- mice fed a high-fat high-cholesterol diet

Apolipoprotein E knock out (ApoE−/−) mice, the widely used model for atherosclerosis, exhibits anti-obesity characteristics due to the impaired lipoprotein internalization. Since excessive accumulation of triglycerides and cholesterol in white adipose tissue (WAT) is shown to increase the risk of metabolic diseases, we investigated the effects of dietary high-fat high-cholesterol (HFHC) on gene expression profile […]
