This study aims to investigate whether frailty severity in conjunction with cognitive function, termed as” cognitive frailty”, is associated with dietary diversity in older adults. This cross-sectional study used the data from the 2014–2016 Nutrition and Health Survey in Taiwan (N = 1115; age ≥ 65 years). Dietary intake was assessed using a 24 h dietary recall and food-frequency questionnaire, and dietary diversity score (DDS; range, 0–6) and food intake frequency were calculated. The presence of frailty phenotypes was determined using the FRAIL scale, which was proposed by the International Association of Nutrition and Aging, and cognitive function was assessed using the Mini–Mental State Examination (MMSE) score. The prevalence of cognitive frailty (FRAIL scale score ≥ 3 and MMSE score ≤ 26) was 4.2%. A higher consumption frequency of dairy products, whole grains, vegetables, fruit, fish and seafood, nuts, tea, and coffee, as well as lower pickled vegetable, was inversely associated with cognitive frailty. Those with prefrailty or frailty and lower DDS demonstrated a higher cognitive impairment risk (adjust odds ratio (OR) = 2.15, 95% confidence interval = 1.21–3.83) than those without frailty and higher DDS. Older adults with cognitive prefrailty or cognitive frailty were associated with lower DDS, and frailty with lower DDS was associated with worsening cognitive function.

Few studies on humans have comprehensively evaluated the intake composition of methyl-donor nutrients (MDNs: choline, betaine, and folate) in relation to visceral obesity (VOB)-related hepatic steatosis (HS), the hallmark of non-alcoholic fatty liver diseases. In this case–control study, we recruited 105 patients with HS and 104 without HS (controls). HS was diagnosed through ultrasound examination. VOB was measured using a whole-body analyzer. MDN intake was assessed using a validated quantitative food frequency questionnaire. After adjustment for multiple HS risk factors, total choline intake was the most significant dietary determinant of HS in patients with VOB (Beta: −0.41, p = 0.01). Low intake of choline (<6.9 mg/kg body weight), betaine (<3.1 mg/kg body weight), and folate (<8.8 μg/kg body weight) predicted increased odds ratios (ORs) of VOB-related HS (choline: OR: 22, 95% confidence interval [CI]: 6.5–80; betaine: OR: 14, 95% CI: 4.4–50; and folate: OR: 19, 95% CI: 5.2–74). Combined high intake of choline and betaine, but not folate, was associated with an 81% reduction in VOB-related HS (OR: 0.19, 95% CI: 0.05–0.69). Our data suggest that the optimal intake of choline and betaine can minimize the risk of VOB-related HS in a threshold-dependent manner.

Many studies have demonstrated that coparenting and parenting behaviors have a substantial effect on the behaviors of young children. Research has indicated that young children may exhibit picky eating behaviors, which pose challenges for parents in terms of coparenting and parenting. This study examined how dietary coparenting and parenting strategies directly affect young children’s picky eating behaviors and explored the mediating role of parenting strategies in the relations between parental dietary coparenting and young children’s picky eating behaviors. More specifically, this study focused on parents of three- to six-year-old children in northern Taiwan. A total of 408 valid completed questionnaires were collected, and the research tools included scales measuring dietary coparenting, parenting strategies, and young children’s picky eating behaviors. The results revealed that supportive and undermining dietary coparenting and parenting strategies had a significant direct effect on young children’s picky eating behaviors. Furthermore, supportive and undermining dietary coparenting partially mediated young children’s picky eating behaviors through parenting strategies. Specifically, among parenting strategies, both “encouraging and facilitating the trying of new foods” and “guiding and modeling” proper eating behaviors had significant indirect effects on reducing young children’s picky eating behaviors.

Objective: To assess the prospective association between frailty and dietary diversity on mortality. Method: This prospective cohort study used the 2005–2008 Nutrition and Health Survey in Taiwan (N = 330; age ≥ 65 years) and this was linked to the Death Registry where we used the data that was recorded up to 31 January 2020. Dietary intake information was assessed using a 24-h dietary recall and food-frequency questionnaire, which were calculated a dietary diversity score (DDS; range, 0–6) and food consumption frequency. Assessment of frailty phenotypes was based on FRAIL scale which was proposed by the International Academy on Nutrition and Aging. Results: Frail older adults had a higher risk of all-cause mortality when they were compared to those with robust physiologies (hazard ratio [HR]: 3.73, 95% confidence interval [CI]: 2.13–6.52). Frailty and a lower DDS were associated with a higher risk of mortality (joint adjusted HR: 2.30, 95% CI: 1.11–4.75) which, compared with a robust physiology and higher DDS, were associated with a lower risk of mortality. Conclusions: Frailty and a lower DDS were associated with a higher mortality. Prefrailty and frailty with a higher DDS were associated with a lower risk of mortality when compared with those with prefrailty and frailty and a lower DDS. These results suggest that eating a wide variety of foods might reduce the risk of mortality in older adults with prefrailty and frailty.

Background: Picky eating behaviors among children challenge nutritional intake and healthy development and place considerable stress on parents. Parenting approaches play a critical role in shaping young children’s dietary behaviors. Mindful parenting, which refers to parents responding to their child’s needs with awareness, acceptance, attention, and mindful discipline, has gained increasing attention. Parental dietary competence may determine whether mindful parenting effectively discourages picky eating behavior in children. Objectives: This study explored whether mindful parenting and parental dietary competence are associated with picky eating behaviors in young children. The mediating role of parental dietary competence in this association was also investigated. Methods: A total of 412 parents of children enrolled in six preschools across six administrative districts in New Taipei City, Taipei City, and Taoyuan City, Taiwan, were invited and recruited. Data were collected using three validated parent-reported instruments, including a mindful parenting scale, parental dietary competence scale, and children’s picky eating behaviors scale. Results: Mindful parenting influenced children’s picky eating behaviors through the full mediation of parental dietary competence. The identification of parental dietary competence as a mediator underscores the need for early preventive interventions and parenting education that integrate parental mindfulness and dietary competence to foster healthy eating habits from the outset of early childhood. Conclusions: Practical recommendations and future research directions are provided regarding mindful parenting, parental dietary competence, and picky eating behaviors in young children.

Objective: This study aimed to assess the association between sugar-sweetened beverage (SSB) consumption and psychological distress. Design: This study used a cross-sectional design. Setting: The database from the 2013–2016 Nutrition and Health Survey in Taiwan (NAHSIT) was used for this study. Participants: There are 3787 Taiwanese adults aged 19–64 in the NAHSIT database. Measurements: The simplified food frequency questionnaire was used to assess the frequency of SSB intake, and a 24 h dietary recall was used for nutrient calculations. Subsequently, a logistic regression model was used to examine the association between the frequency of SSB consumption and psychological distress. Result: The risk of psychological distress with SSBs consumed 1–6, 7–13, and ≥14 times per week was (adjusted odds ratio (aOR) = 1.75, 95% CI = 1.50–2.04), (aOR = 1.56, 95% CI = 1.32–1.84), and (aOR = 1.99, 95% CI = 1.64–2.42), respectively. Participants who consumed SSBs ≥14 times per week had a significantly lower intake of whole grains, milk, vegetables, fruits, and nuts and seeds, while their consumption frequency of eggs, dairy products, soybean products, pickled vegetables, meat products, tea, coffee, desserts and snacks, and fried foods was significantly higher. Conclusions: SSB consumption was significantly positively associated with psychological distress. Future interventional studies could further explore the potential directionality of this association.
