Gene-diet interaction using a multifactorial approach is preferred to study the multiple risk factors of cardiovascular disease (CVD). This study examined the association and gene-diet interaction effects of the angiotensin II type 1 receptor () gene (rs5186), and type 2 receptor () gene (rs1403543) polymorphisms on metabolic risk factors of CVD in Malaysian adults. CVD parameters (BMI, blood pressure, glycated hemoglobin, total cholesterol (TC), triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), and TC/HDL-C ratio), and constructed dietary patterns "vegetables, fruits, and soy diet" (VFSD), and "rice, egg, and fish diet" (REFD) were obtained from previous studies.

The circulating levels of β-carotene are modulated not only by sex, but also by autosomal gene variations and fruit intake. The aim of this study was to investigate the interactions between β-carotene metabolism-related gene single nucleotide polymorphisms (SNPs; genetic factors) and nutrient intake (environmental factors) relating to their effects on circulating β-carotene. The serum concentrations of β-carotene and the habitual food intake of 92 healthy Japanese adults were examined.

Article Synopsis
  • - The study aimed to examine how common irritable bowel syndrome (IBS) is among young Japanese women and how factors like mental health, physical activity, and diet influence it, using a combination of questionnaires for data collection.
  • - It found that 12% of participants had IBS, with constipation-predominant IBS being more common than diarrhea-predominant IBS, and noted that IBS individuals tended to be more anxious, more physically active, and had different dietary habits compared to non-IBS participants.
  • - The study concluded that the prevalence rates of IBS were consistent with other research, suggesting that a variety of factors—mental, physical, and nutritional—play a significant role in its development.

Background/aims: Dietary pattern and genetic predisposition of each population have different impacts on lifestyle-related chronic diseases. This study was conducted to evaluate the association and interaction between dietary patterns and VEGFR2 or KDR gene polymorphisms on physical and biochemical risk factors of cardiovascular disease in two Asian populations (179 Chinese Malaysian and 136 Japanese adults).

Methods: Dietary patterns were constructed from food frequency questionnaire using factor analysis.

Background/aims: The prevalence of lifestyle-related chronic diseases is increasing and gene-diet interaction studies are limited among the Malaysian population. This study was conducted to evaluate the association and interaction effects of vascular endothelial growth factor receptor-2(VEGFR2) gene polymorphisms and dietary patterns on anthropometric and biochemical risk factors of chronic diseases in 179 Chinese Malaysian adults.

Methods: Genotyping of rs1870377 and rs2071559 was performed by real-time PCR using TaqMan probes.

Many epidemiological studies have examined the associations of nutrients and foods with risk of stomach cancer. Few studies have addressed the dietary patterns that reflect various components of food consumption and their interactions. We identified major four dietary patterns; "vegetable and fruit", "Western breakfast", "meat", and "rice/snack" with principal component analysis using food consumption questionnaire in a prospective study of 5,765 middle-aged male workers in Tokyo.
