Introduction: Healthy dietary patterns may prevent many chronic diseases, and is emphasized by 2015 US dietary guideline, but it remains unclear which dietary patterns may be benefit to prevention of primary liver cancer (PLC).
Materials And Methods: We recruited 782 PLC cases and 1:1 age- and sex-matched controls in Guangzhou, China. Habitual dietary intake was assessed by face-to-face interview using a 79-item food frequency questionnaire, and used to explore dietary patterns by factor analysis.
Results: Three dietary patterns were identified: 1) an urban prudent dietary pattern (UPDP) characterized by high in dairy products, eggs, mushrooms, nuts and soy foods, but low in refined grains; 2) a traditional Cantonese dietary pattern (TCDP) consisting of a high intake of fruit and vegetables, fish, Cantonese soup, and Chinese herb tea; and 3) a high meat and preserved food pattern (MPFP). Multivariable analyses showed favorable associations for the first two dietary patterns, but unfavorable association for the last one (all -trend < 0.01). Odds ratios (95% CI) of PLC for the highest (vs. lowest) quartile of pattern scores of the three patterns were 0.25 (0.18-0.35), 0.61 (0.46-0.82), and 1.98 (1.46-2.69), respectively.
Conclusions: Our findings suggest that the UPDP and TCDP were associated with lower, whereas the MPFP with higher, risk of PLC.

Background & Aim: Metabolic and cardiovascular health outcomes are strongly influenced by diet. Dietary habits established in early childhood may persist into adulthood. This study aimed to examine the association between dietary patterns at both 2 and 8 years of age, explaining the maximum variability of high- and low-quality fats, sugars, and fibre, and cardiometabolic markers at age 8 years.

Background: Intimate partner violence (IPV) poses a significant threat to the well-being of women and girls and is a highly prevalent form of gender-based violence. Evidence regarding the nutritional implications of IPV has focused primarily on intergenerational relationships with child nutrition and growth. There remains a knowledge gap regarding the association with women's own dietary intake.

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), which is increasingly being recognized as a leading cause of chronic liver pathology globally, is increasing. The pathophysiological underpinnings of its progression, which is currently under active investigation, involve oxidative stress. Human adipose tissue, an integral endocrine organ, secretes an array of adipokines that are modulated by dietary patterns and lifestyle choices.

In recent years, research on taste perception has increasingly focused on its influence on food consumption, preferences, and long-term health. While bitter and sweet tastes have been well-studied, less is known about salty and umami tastes and their effects on dietary habits. This study aimed to address this gap by exploring sensory-hedonic patterns for 'savory' stimuli, encompassing both umami and salty tastes, in a representative sample of Italian adults, with a focus on gender-specific differences.
