A comprehensive self-administered diet history questionnaire (DHQ: 150-item semi-quantitative questionnaire) and a brief self-administered DHQ (BDHQ: 58-item fixed-portion-type questionnaire) were ...developed for assessing Japanese diets. We compared the relative validity of nutrient intake derived from DHQ with that from the BDHQ, using semi-weighed 16-day dietary records (DRs) as reference.
Ninety-two Japanese women aged 31 to 69 years and 92 Japanese men aged 32 to 76 years completed a 4-nonconsecutive-day DR, a DHQ, and a BDHQ 4 times each (once per season) in 3 areas of Japan (Osaka, Nagano, and Tottori).
No significant differences were seen in estimates of energy-adjusted intakes of 42 selected nutrients (based on the residual method) between the 16-day DRs and the first DHQ (DHQ1) or between the DR and the first BDHQ (BDHQ1) for 18 (43%) and 14 (33%) nutrients, respectively, among women and for 4 (10%) and 21 (50%) nutrients among men. The median (interquartile range) Pearson correlation coefficients with the DR for energy-adjusted intakes of the 42 nutrients were 0.57 (0.50 to 0.64) for the DHQ1 and 0.54 (0.45 to 0.61) for the BDHQ1 in women; in men, the respective values were 0.50 (0.42 to 0.59) and 0.56 (0.41 to 0.63). Similar results were observed for the means of the 4 DHQs and BDHQs.
The DHQ and BDHQ had satisfactory ranking ability for the energy-adjusted intakes of many nutrients among the present Japanese population, although these instruments were satisfactory in estimating mean values for only a small number of nutrients.
In recent years, there have been reports suggesting a high prevalence of low vitamin D intakes and vitamin D deficiency or inadequate vitamin D status in Europe. Coupled with growing concern about ...the health risks associated with low vitamin D status, this has resulted in increased interest in the topic of vitamin D from healthcare professionals, the media and the public. Adequate vitamin D status has a key role in skeletal health. Prevention of the well‐described vitamin D deficiency disorders of rickets and osteomalacia are clearly important, but there may also be an implication of low vitamin D status in bone loss, muscle weakness and falls and fragility fractures in older people, and these are highly significant public health issues in terms of morbidity, quality of life and costs to health services in Europe. Although there is no agreement on optimal plasma levels of vitamin D, it is apparent that blood 25‐hydroxyvitamin D 25(OH)D levels are often below recommended ranges for the general population and are particularly low in some subgroups of the population, such as those in institutions or who are housebound and non‐Western immigrants. Reported estimates of vitamin D status within different European countries show large variation. However, comparison of studies across Europe is limited by their use of different methodologies. The prevalence of vitamin D deficiency often defined as plasma 25(OH)D <25 nmol/l may be more common in populations with a higher proportion of at‐risk groups, and/or that have low consumption of foods rich in vitamin D (naturally rich or fortified) and low use of vitamin D supplements. The definition of an adequate or optimal vitamin D status is key in determining recommendations for a vitamin D intake that will enable satisfactory status to be maintained all year round, including the winter months. In most European countries, there seems to be a shortfall in achieving current vitamin D recommendations. An exception is Finland, where dietary survey data indicate that recent national policies that include fortification and supplementation, coupled with a high habitual intake of oil‐rich fish, have resulted in an increase in vitamin D intakes, but this may not be a suitable strategy for all European populations. The ongoing standardisation of measurements in vitamin D research will facilitate a stronger evidence base on which policies can be determined. These policies may include promotion of dietary recommendations, food fortification, vitamin D supplementation and judicious sun exposure, but should take into account national, cultural and dietary habits. For European nations with supplementation policies, it is important that relevant parties ensure satisfactory uptake of these particularly in the most vulnerable groups of the population.
Literature reports suggest that subjective sleep quality is associated with nutrient intake in elderly people and workers. However, few studies have suggested an association between objective sleep ...quality and dietary intake in adolescents and young women. We hypothesized that objective sleep quality is associated with dietary intake in adolescents and young women. We evaluated the association between energy and nutrient intake and objective sleep quality in adolescents and young Japanese women. In a cross-sectional study of 80 women aged 18-27 years, dietary intake was assessed using the self-administered diet history questionnaire. Objective sleep quality was assessed by actigraphy. Lifestyle characteristics, dietary habits, and mental health were assessed using specific questionnaires. Subjects were classified into 3 groups according to sleep efficiency (SE <80%, 80%-85%, and ≥85%), and the relationships between dietary intake and objective sleep quality were statistically evaluated. No significant differences occurred in lifestyle characteristics, physical activity levels, eating behavior, and mental health status among the 3 SE groups. Energy intake was significantly lower in the low-SE group than in the middle- (P = .004) and high- (P = .015) SE groups. Protein intake was significantly lower in the low-SE group than in the high-SE group (P = .034). The mean energy-adjusted intakes of vitamin K, vitamin B2, potassium, magnesium, iron, zinc, copper, and tryptophan were significantly lower in the low-SE group than in the high-SE group. Adequate energy intake and a high-quality diet including vitamins, minerals, and tryptophan may result in high sleep quality and help prevent sleep problems.
For most mammals, including nonhuman primates, diet composition varies temporally in response to differences in food availability. Because diet influences gut microbiota composition, it is likely ...that the gut microbiota of wild mammals varies in response to seasonal changes in feeding patterns. Such variation may affect host digestive efficiency and, ultimately, host nutrition. In this study, we investigate the temporal variation in diet and gut microbiota composition and function in two groups (N = 13 individuals) of wild Mexican black howler monkeys (Alouatta pigra) over a 10-month period in Palenque National Park, Mexico. Temporal changes in the relative abundances of individual bacterial taxa were strongly correlated with changes in host diet. For example, the relative abundance of Ruminococcaceae was highest during periods when energy intake was lowest, and the relative abundance of Butyricicoccus was highest when young leaves and unripe fruit accounted for 68 % of the diet. Additionally, the howlers exhibited increased microbial production of energy during periods of reduced energy intake from food sources. Because we observed few changes in howler activity and ranging patterns during the course of our study, we propose that shifts in the composition and activity of the gut microbiota provided additional energy and nutrients to compensate for changes in diet. Energy and nutrient production by the gut microbiota appears to provide an effective buffer against seasonal fluctuations in energy and nutrient intake for these primates and is likely to have a similar function in other mammal species.
Chronotype reflects an individual's preferred time of the day for an activity/rest cycle and individuals can be classified as a morning, intermediate, or evening type. A growing number of studies ...have examined the relationship between chronotype and general health. This review aimed to map current evidence of the association between chronotype and dietary intake among the adult population. A systematic search was conducted across five databases: EBSCO Host, Medline & Ovid, Pubmed, Scopus, and The Cochrane Library. The inclusion criteria were adult subjects (more than 18 years old), and included an assessment of (i) chronotype, (ii) dietary behaviour/nutrient intake/food group intake, and (iii) an analysis of the association between chronotype and dietary behaviour/nutrient intake/food group intake. A total of 36 studies were included in the review. This review incorporated studies from various study designs, however, the majority of these studies were based on a cross-sectional design (
= 29). Dietary outcomes were categorized into three main groups, namely dietary behaviour, nutrient intake, and specific food group intake. This scoping review demonstrates that evening-type individuals are mostly engaged with unhealthy dietary habits related to obesity and were thus hampered in the case of weight loss interventions. Hence, this review has identified several dietary aspects that can be addressed in the development of a personalised chrono-nutrition weight loss intervention.
The amount of dietary protein needed to prevent deficiency in most individuals is defined in the United States and Canada by the Recommended Dietary Allowance and is currently set at 0.8 g protein · ...kg ⁻¹ · d ⁻¹ for adults. To meet this protein recommendation, the intake of a variety of protein food sources is advised. The goal of this article is to show that commonly consumed food sources of protein are more than just protein but also significant sources of essential nutrients. Commonly consumed sources of dietary protein frequently contribute substantially to intakes of nutrients such as calcium, vitamin D, potassium, dietary fiber, iron, and folate, which have been identified as nutrients of “concern” (i.e., intakes are often lower than recommended). Despite this, dietary recommendations to reduce intakes of saturated fat and solid fats may result in dietary guidance to reduce intakes of commonly consumed food sources of protein, in particular animal-based protein. We propose that following such dietary guidance would make it difficult to meet recommended intakes for a number of nutrients, at least without marked changes in dietary consumption patterns. These apparently conflicting pieces of dietary guidance are hard to reconcile; however, we view it as prudent to advise the intake of high-quality dietary protein to ensure adequate intakes of a number of nutrients, particularly nutrients of concern.
•Proportions of children who met the DRIs were similar despite food neophobia status.•Food neophobia was negatively associated with protein, iron, and cholesterol intake.•Food neophobia was ...associated with lower intake of several micronutrients.
Food neophobia is a widely prevalent eating behavior among children, which has been linked to poor dietary variety and quality. Nevertheless, data pertaining nutrient intakes in relation to food neophobia among children in Middle East countries are lacking. The present study aimed to examine the associations between food neophobia and nutrient intakes in children aged 6–12 years. A cross-sectional study of 424 children was conducted. Food neophobia among children was evaluated using the Food Neophobia Scale. Dietary data of children were collected using 24-hour dietary recalls, and nutrient densities were calculated. Intakes of macro- and micronutrients were compared to dietary recommendations. Proportions of children who met the dietary recommendations for all nutrients were similar across food neophobia groups. No significant difference in macro- or micronutrient intake was observed across categories of food neophobia in univariate analyses; however, in multiple regression models, higher food neophobia score was associated with lower protein intake (β = -0.04% of total energy, 95% CI −0.07 to −0.01), cholesterol (β = -1.79 mg/1000 kcals, 95% CI −3.51 to −0.06), potassium (β = -11.02 mg/1000 kcals, 95% CI −20.5 to −1.54), phosphorus (β = -5.30 mg/1000 kcals, 95% CI −9.74 to −0.86), magnesium (β = -1.20 mg/1000 kcals, 95% CI −2.15 to −0.25), iron (β = -0.07 mg/1000 kcals, 95% CI −0.14 to −0.01), zinc (β = -0.04 mg/1000 kcals, 95% CI −0.07 to −0.001), and selenium intake (β = -0.48 ug/1000 kcals, 95% CI −0.93 to −0.04). Our findings suggest negative associations between food neophobia in children and intake of a number of important nutrients. Further investigations are needed to identify potential factors that could influence food and nutrient intake among food neophobic children.
Among Liver Transplantation (LT) recipients malnutrition is ubiquitous due to various metabolic aberrations and poor nutrient intake. It is imperative to recognize the diverse aspects which can alter ...patients’ food and nutrient intake.
The study aimed to provide the much-needed data on various conducive and deterrent factors for calorie and protein intake of the pre-LT patients.
In the present exploratory study 54 adult pre-LT patients were purposively selected. Information regarding patient's personal, medical history, nutrient, and dietary intake through 24- Hour Dietary recall and other factors like appetite (SNAQ), number of meals, duration of present illness, excessive fatigue, ascites, sound sleep, functional status, advice to increase intake, supplement recommended were gathered by patients’ interviews and OPD visits.
The data showed significantly lower-calorie, protein, and calcium intake among pre-LT recipients as per the recommendations (p < 0.001**). Patients were consuming more than 40% of the calories and 20% of proteins from cereals. The Stepwise forward regression analysis showed the relationship between calorie and protein intake (dependent variable) with other independent variables. Calorie intake increased by 73.4 units (p < 0.01**) with a unit increase in appetite score (SNAQ). Protein intake increased by 9.3 units with a unit increase in the number of meals consumed (p = 0.001**). Calorie and protein intake decreased by 252.8 units and 15.6 units respectively with a unit increase in the number of days dietary advice for improving the food intake was not given (p < 0.01). Also, a unit increase in the number of days patients had sound sleep, increased calorie and protein intake by 167.4 units and 10.3 units respectively (p < 0.05).
Higher appetite, sound sleep, and higher numbers of meals consumed were conducive factors for calorie and protein intake among patients in the pre-transplant phase while no dietary advice for improving food intake was shown to be a deterrent factor. While planning diet, considerations and appropriate alterations of these factors can positively regulate the nutrient intake and nutritional status of the pre-LT patients.
