An ensemble method based on marginal-effect models (EMM) for estimating usual food intake from single-day dietary data and internal/external two-day dietary data

Background: With collection of repeated 24-hour recalls, there exist challenges in usual intake estimation, including infeasibility of multiple dietary assessments, and shortage of non-zero intakes for episodically consumed foods. Objectives: We developed an ensemble method based on marginal-effect models (EMM), which estimates usual intake distribution using single-day data with internal or external two-day data. Methods: […]

Soybean product consumption decreases risk of gastric cancer: results from the Health Examinees Study

Background: Epidemiological findings on the association between soybean product consumption and gastric cancer risk remain inconsistent. We evaluated the relationship between soybean product consumption and the risk of gastric cancer in a prospective cohort study in Korea. Methods: This prospective cohort study included a total of 139,267 participants aged 40–69 years from the Health Examinees-Gem […]

Associations of body mass index and weight change with circulating levels of high-sensitivity C-reactive protein, proinflammatory cytokines, and adiponectin among breast cancer survivors

Aim: This study examined the associations of body mass index (BMI) and weight change with inflammatory markers among breast cancer survivors in Korea. Methods: A total of 495 women were included who had been diagnosed with primary breast cancer and survived for at least 6 months since the surgery. Information on the body weight and […]

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 […]

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, […]
