Abstract

Purpose

Developed countries have devised guidelines for various eating habits, many of which simply recommend “eating various foods” without specifying how much food the individual should consume each day. The authors aimed to examine the relationship between the variety of food consumed and the probability of nutritional adequacy in middle‐aged Japanese.

Design/methodology/approach

In total, 215 subjects (102 men and 113 women) provided complete dietary records for seven days in each of the winter, spring, summer and autumn. Subjects were categorized into groups of five according to the amount of each food eaten per day, calculated energy, and nutrients in the food. Results were compared with respective indicators of nutrition defined by the Dietary Reference Intakes for Japanese (2010).

Findings

The percentage of overweight subjects was higher in the group that did not consume a wide variety of foods. Intake of energy, calcium, zinc, magnesium, vitamins B1, B2 and C were insufficient in the subjects who did not consume a wide variety of foods. Although a trend toward sufficient nutrient intake was observed in the group that consumed a variety of foods, the estimated average requirement for several nutrients such as calcium and zinc was below accepted standards for good nutrition.

Originality/value

The variety of foods eaten is related to the adequacy of intake levels of certain nutrients and to body mass index in middle‐aged Japanese subjects. Eating a wide variety of foods is important to ensuring adequate nutrient intake.

Abstract

Purpose

This study estimates the income elasticities of calorie, macronutrients (carbohydrate, protein and fat) and key micronutrients including cholesterol, vitamin A, vitamin C, sodium, potassium, calcium, iron, zinc and insoluble fiber separately for urban and rural adults aged 18–60, using China Health and Nutrition Survey data set from 2004 to 2011.

Design/methodology/approach

A semiparametric model, a two-way fixed-effects model and a quantile regression approach are employed to estimate nutrient–income elasticities.

Findings

The income elasticities of calorie, protein, fat, cholesterol and calcium are in the range of 0.059–0.076, 0.059–0.076, 0.090–0.112, 0.134–0.230, 0.183–0.344 and 0.058–0.105, respectively. The income elasticity of each of the other nutrients is less than 0.1. The income elasticities of calorie and the majority of nutrients included are larger for rural residents than for urban residents and for low-income groups than for medium- and high-income groups. Overall, in spite of having a relatively small impact, income growth is shown to still have an impact on improving the nutritional status of Chinese adults.

Originality/value

This study estimates nutrient–income elasticities separately for urban and rural adults, expanding the scope of the study regarding the impact of income on the nutritional status in China. Moreover, this study uses a pooled sample generated from the personal food consumption records covering foods consumed at home and away from home during 2004–2011, which is thus likely to more comprehensively reveal the causal relationship between income growth and changes in the nutritional status in China.

Abstract

Many committees have produced tables of recommended dietary intakes. All are careful to stress that their recommendations are amounts sufficient, or more than sufficient, for the nutritional needs of practically all healthy persons in the population but are not a precise statement of nutrient requirements. The recommendations may ‘serve as guides for government officials and others whose duty it is to plan agricultural production and to control imports and exports of food in order to ensure that the food supply will be sufficient to meet the needs of the people’ and ‘may be used as a guide for caterers and dietitians when planning diets for groups of healthy individuals’

This paper aims to investigate the relationship between locomotive syndrome (LS) and insufficient nutrient intake in young and middle-aged adults, independent of energy intake.

Abstract

Purpose

This paper aims to investigate the relationship between locomotive syndrome (LS) and insufficient nutrient intake in young and middle-aged adults, independent of energy intake.

Design/methodology/approach

The authors conducted a cross-sectional survey of a non-random sample of 219 adults aged 18 to 64 (175 men and 44 women) working in two companies in Japan, between December 2018 and March 2019. LS Stage 0 was classified as No-LS while Stages 1 and 2 were classified as LS. Nutrient intake was assessed using a brief-type self-administered diet history questionnaire and adjusted to the required energy intake for each participant. The criteria for sufficient intake of 22 nutrients were based on the Dietary Reference Intake for Japanese. Logistic regression model was used to analyze the association between LS and insufficient nutrient intake.

Findings

In total, 234 employees participated in the LS examinations while 219 of them completed the questionnaire giving a response rate of 93.6%. LS Stages 1 or 2 were present in both men and women in all the age-stratified groups except for the women in their 60s. There was a significant association between LS status and insufficient intake of Vitamin K (odds ratio [95% confidence interval] 16.0 [range: 1.1–407]; p = 0.01) in women, but not in men.

Research limitations/implications

The result suggests that attention should be paid to adequate Vitamin K intake in young and middle-aged women with LS. Future studies should be conducted using a larger and more diverse sample.

Originality/value

To the best of the authors’ knowledge, the present paper is the first study to show an association between LS in young and middle-aged adults and nutrients that are independent of energy intake.

Abstract

Purpose

The association between nutrition and cognitive test performance among school children is limited in developing countries, including Ghana. This paper aims to investigate the relationship between nutrient intake and cognitive competence in the context of abstract reasoning among school-aged children in the Tamale Metropolis.

Design/methodology/approach

The present cross-sectional study recruited 596 children aged 9–13 years from government-owned and private primary schools in Tamale Metropolis. Dietary intake was assessed by using three-day repeated 24-hour recall. Cognition was assessed by the Raven’s Coloured Progressive Matrices (RCPM) test, made up of 36 questions and used as a continuous variable, whereby higher scores indicated better cognition.

Findings

The majority of the children did not meet the recommended dietary allowances for protein (55.5%) and fibre (94.0%) and estimated adequate requirement for energy (86.6%), folate (72.8%), vitamin E (90.6%) and zinc (74.8%). More girls (55.1%) performed poorly in the cognition test than the boys (45.7%) (p = 0.029). Between-subject effects determined using univariate and multivariate analyses indicated age (p = 0.002), dietary folate (p = 0.016), vitamin C intake (p = 0.011), combined age and dietary folate (p = 0.049) and combined age and dietary vitamin C (p = 0.022) significantly affected cognition scores. Girls had lower odds (AOR = 0.7, p = 0.021, 95%CI = 0.5–0.9) of scoring above the 50th percentile in cognition test than boys.

Research limitations/implications

The current nutrient intakes of the children were inadequate. The children performed poorly in Raven’s cognition test of abstract reasoning, and this was associated with being a girl.

Originality/value

To the best of the authors’ knowledge, this study is the first to investigate nutrient intakes and RCPM test performance among children in Northern Ghana. Thus, the findings of the study provide relevant information needed by stakeholders to implement nutrition programs in basic schools, aimed at ensuring optimal nutrition achievement among school children for improved cognition.

Abstract

Although it is possible to achieve a balanced diet by eating a variety of foods, it is clear that there is a gap between the ideal and the reality of what people actually eat. For individuals at all stages of life and with changing lifestyles where food selections may compromise optimal nutrition, nutrient‐dense foods including fortified foods and food supplements can serve as an effective means of ensuring that micronutrient needs are fulfilled. Populations at risk include the elderly, women at various life stages, children and adolescents, and people trying to lose weight. Efficacy and safety are key health issues: efficacy refers to the ability of vitamins and minerals either to prevent a deficiency, to enhance a physiological effect or to reduce the risk of disease; safety refers to the safe intake of a micronutrient to avoid adverse effects. Safety is the fundamental tenet of the scientific risk assessments and the cornerstone of food safety policy and legislation. Harmonisation of laws on food fortification and food supplements at EU level will help to ensure a high level of public health and consumer protection and facilitate the free circulation of food products within the community.

Abstract

Purpose

The purpose of this paper is to investigate the linkages between climate change, income dynamics and nutrition intake in rural China.

Design/methodology/approach

Using a system of simultaneous equations in a three-stage least squares model instrumented with carbohydrates, fats, proteins and farm income the authors found generally that the greatest impact on nutrition would be from changes in temperature.

Findings

The authors do not find that modest changes in precipitation affect nutrient intake, but extreme events such as drought do. Furthermore, the authors found a strong income effect and this income effect is opposite the heating effect. This may suggest that large swings in nutrient intake brought about by climate change may be countermanded by equivalent increases in income. The authors also found that in terms of general measures of elasticity that market effects, especially in the price of meats, can impact carbohydrate, fat and protein intake as much as global warming.

Originality/value

The authors believe that three aspects of this manuscript will make it interesting. First, in the short term, poorer households would be the most vulnerable and sensitive to climate change. However, in the long term, all households in rural China appear able to deal with changing climatic conditions through adaptation. Second, the authors do not find evidences to prove the existence of a poverty nutrition trap in rural China. Third, the results also indicate that, the nutrition intake of households in rural China is more prone to gradual changes, rather than extreme events.

Abstract

Purpose

It has been suggested that there is a link between the dietary intake of certain nutrients and the risk of prostate cancer. The aim of this study is to examine the associations between dietary intakes of all nutrients and the risk of prostate cancer in Kermanshah.

Design/methodology/approach

This case-control study was conducted in Kermanshah, a province in the west of Iran in November of 2016. The sample consisted of 50 patients with confirmed prostate cancer, and 150 healthy men who matched in age with these cases and did not have any symptoms of prostate disorder were chosen as controls. Dietary intakes were collected by a semi-quantitative food frequency questionnaire that contained 147 food items and were then analyzed by Nutritionist 4 software.

Findings

After adjustment for potential confounding factor, highest tertile compared to lowest tertile of dietary vitamin E intake [odds ratio (OR) = 0.21; 95% confidence interval (CI) = 0.05-0.89], lycopene intake (OR = 0.11; 95% CI = 0.01-0.86) and magnesium intake (OR = 0.02; 95% CI = 0.01-0.55) had a protective effect on the incidence of prostate cancer. However, there were no associations between dietary intakes of fiber, vitamin A, vitamin D, vitamin B12, folate and calcium with prostate cancer.

Originality/value

The finding suggests that the dietary intakes of vitamin E, lycopene and magnesium could decrease the risk of prostate cancer. Nevertheless, dietary intake of other nutrients such as fiber, calcium, vitamins D, A, B12 and folate was not associated with prostate cancer.

Abstract

Reports the results of a survey of followers of the mostly raw, pure vegetarian, Hallelujah diet, which is promoted by the Hallelujah Acres Foundation in the USA. Seven‐day semi‐quantitative dietary records kept by 141 followers of the diet were collected and analyzed for nutrient intake. Claims self‐reported improvements in health and quality of life after adoption of the diet were significant (p < 1E‐07). Mean daily consumption of fruits and vegetables was 6.6 servings and 11.4 servings, respectively. Salads, fruits, carrot juice and grain products provided 60‐88 per cent of most nutrients. The mean energy intake was 1,460kcal/day for women and 1,830kcal/day for men. Claims that, with some modifications, this diet pattern allows people to adopt a low calorie diet sufficient in most nutrients.

Abstract

Purpose

The purpose of this study was to assess nutrient intakes in elderly living in Lebanese nursing homes (NHs).

Design/methodology/approach

This cross-sectional study was conducted in 36 long-term care institutions from all over Lebanon. Out of 2,094 residents, 98 (69 women and 29 men) elderly met the inclusion criteria and successfully completed the interview question. Dietary food intake was assessed using the 24-h food recall. The analysis used a Chi-square test and independent samples t-test or Mann–Whitney test, as appropriate.

Findings

A high percentage of elderly (reaching 100 per cent) had a low intake of energy, protein, linolenic acid, linoleic acid, fibers, vitamins and minerals, and the prevalence of nutrient inadequacy was significantly different between sexes for copper intake (p = 0.02). The results of this study highlight the nutrient inadequacies among the majority of elderly living in long-term care institutions and particularly in women and elderly residing in NHs located away from the capital Beirut.

Originality/value

This study is quite original; this is the first study performed nationwide in Lebanon covering not only the largest number of NHs in various locations but also elderly under custodial settings and with diverse backgrounds.
