Deficiency of Energy and Nutrient and Gender Differences among Chinese Adults: China Nutrition and Health Survey (2015-2017).

Half of Chinese adults face the double burden of overweight/obesity and micronutrient deficiencies, and nearly 40% of them are severely overweight/obese or have micronutrient deficiencies. This study used the data from China Nutrition and Health Survey (CNHS) from 2015 to 2017 to estimate the prevalence of inadequate dietary micronutrient intake (including vitamin A, vitamin B1, vitamin B2, vitamin C, cCalcium, iron and sodium) in Chinese adults and further determine the differences in micronutrient intake by gender, age and BMI. A total of 61,768 subjects were included in this study, of which 33,262 (54%) were female. The intake of energy and all macronutrients decreased with age, and the intake was higher in men than in women. Inadequate energy intake occurs in adults of all ages. In terms of nutrient intake, women had a higher rate of insufficient carbohydrate intake than men in all age groups. Inadequate protein intake was more common in women aged 18-49 years (60.9%) than in men. Compared with women, men had a higher rate of vitamin B2 intake. Insufficient vitamin B3 intake was more common in women aged 18-49 years (35.6%), men aged 65-79 years (39.7%) and men aged 80 years and above (47.9%). In all age groups, insufficient vitamin C intake is higher in women than in men-up to 85.8 percent in women aged 80 years old and above. Compared with men in the same age group, insufficient intake of calcium and iron is more obvious in women. Women have significantly higher rates of inadequate intake of calcium, iron and sodium than men. In the analysis of correlations between BMI or demographic data and micronutrient intakes, the likelihood of micronutrient intakes being insufficient was higher in the central and western regions in all age groups compared to the eastern regions. The risk of insufficient micronutrient intake was higher in obese men and women aged 18-49 years and 50-64 years. Underweight and overweight women in the 65-79 age group were more likely to have inadequate micronutrient intake. Obese women over 80 years of age were less likely to have inadequate micronutrient intake. No significant difference was found between urban and rural areas for each age group.

Effectiveness of Parental Assistance in Providing Food on Nutritional Intake Among Children with Malnutrition

Background: Prevalence of stunting continues to affect 21.3% of children aged <5 years worldwide. The problem of malnutrition in children is caused by several factors, such as poor access to nutritious food, recurrent infections, and inadequate practice of offering food and care for mothers and children during the first 1,000 days.Objectives: The purpose of the study was to know the effectiveness of feeding parenting style assistance to mothers of toddlers in increasing the nutritional intake of under-nutrition childrenMaterials and Methods: This study used a quasi-experimental design with a pre-test and post-test control group design approach. The population in this study was toddlers with malnutrition (according to weight/height). The sample size for each group was 35 mothers. The sample was divided into two groups. The first group was given parental assistance consisting of nutrition education and food processing guidance for the toddler for 3 months (the intervention group) and the second group was given health education about balanced nutrition for children under five (the control group). Collecting data had used a checklist of identity, nutritional status, and semi-quantitative food frequency questionnaire. Data were analyzed using paired t-test, p-value <0.05 for the 95% confidence interval.Results: The nutritional intakes of children under five showed a significant difference between the group of mothers under five who were given intensive assistance (the intervention group) and the group that was only given nutrition education for children under five (the control group). The differences in nutritional intakes seen in macronutrients were the difference in calorie intake (p-value: 0.042; CI: 4.005-213.543) and protein intake (p-value: 0.040; CI: 0.197-8.065). The differences in micronutrient intakes were seen in the increase in consumption of vitamin E (p-value: 0.000; CI: 0.446-4.416), sodium (p-value: 0.000; CI: 61.859-193.741), potassium (p-value: 0.005; CI: 70.743-373.102), calcium (p-value: 0.000; CI: 51.851-137.863), and phosphor (p-value: 0.041; CI: 2.133-99.604).Conclusion: Food parenting assistance for mothers of toddlers was effective in increasing toddler nutrition

Differences in Micronutrient Intakes of Exclusive and Partially Breastfed Indonesian Infants from Resource-Poor Households are Not Accompanied by Differences in Micronutrient Status, Morbidity, or Growth

BackgroundWhen maternal micronutrient intakes and statuses are compromised, reductions in micronutrient concentrations in neonatal stores and human milk may result in suboptimal micronutrient intakes, statuses, and functional outcomes of breastfed infants during the critical first 6-month period. ObjectivesWe compared the adequacy of micronutrient intakes and statuses at 2 and/or 5 months and morbidity and growth faltering at 2, 5, and 12 months in a cohort of exclusively breastfed (EBF) and partially breastfed (PBF) infants from low-resource Indonesian households. MethodsAt 2 and 5 months, the breastfeeding status and human milk intake of 212 infants were determined using the deuterium oxide dose-to-mother technique, and intakes were calculated from milk micronutrient concentrations and 3-d weighed food intakes. At 5 months, five infant micronutrient biomarkers, hemoglobin, C-reactive protein, and α-1-acid-glycoprotein were measured. Infant morbidity, weight, and length were measured at 2, 5, and 12 months. Means, medians, or proportions were reported for each group and differences between groups were statistically determined. ResultsMedian intakes of iron, thiamin, niacin, and vitamin B-12 were higher in PBF than EBF infants at 5 months (all P values < 0.05), but intakes in all infants were below adequate intakes. At 5 months, anemia was <20% in both groups, although fewer PBF versus EBF infants had vitamin B-12 deficiency (11.5% vs. 28.6%, respectively; P = 0.011). The mean ± SD length-for-age z-scores for EBF versus PBF infants at 2 months were 0.7 ± 0.9 versus −0.5 ± 1.1, respectively (P = 0.158), declining to −1.4 ± 0.9 versus −1.1 ± 1.2, respectively, at 12 months (P = 0.059). Reported morbidity rates were generally low, with no evidence of a difference between infant groups (all P values > 0.126). ConclusionsIrrespective of exclusive or partial breastfeeding status, micronutrient intakes of infants were low, statuses were compromised, and growth faltering during the critical 6 months period of early infancy was present. The findings highlight the importance of improving maternal nutritional statuses and evaluating their impacts on infant outcomes.

Micronutrients: Essential Treatment for Inflammatory Arthritis?

Synovial inflammation is characteristic of inflammatory chronic arthropathies and can cause progressive articular damage, chronic pain, and functional loss. Scientific research has increasingly focused on investigating anti-inflammatory micronutrients present in fruits, vegetables, spices, seeds, tea, and wine. This review aims to examine the anti-inflammatory effect of polyphenols (phytonutrients present in plants) and other micronutrients described in randomized clinical trials conducted in patients with chronic inflammatory arthropathies. There is an increasing evidence that differences in micronutrient intake might play an essential role in pathogenesis, therapeutic response, and remission of synovitis. Randomized clinical trials with specific micronutrient- or nutrient-enriched food intake show improvement of symptoms and modulation of both pro- and anti-inflammatory mediators. We found convincing evidence of the anti-inflammatory effect of several micronutrients in arthritis symptoms and inflammation. Although in clinical practice nutritional recommendations to patients with chronic joint inflammation are not consistently prescribed, the addition of these nutrients to day-to-day eating habits could potentially change the natural history of inflammatory arthritis. Future research is needed for a consensus on the specific nutritional recommendations for patients with chronic synovial inflammation.

Organization of Dietary Control for Nutrition-Training Intervention Involving Periodized Carbohydrate Availability and Ketogenic Low-Carbohydrate High-Fat Diet.

The authors describe the implementation of a 3-week dietary intervention in elite race walkers at the Australian Institute of Sport, with a focus on the resources and strategies needed to accomplish a complex study of this scale. Interventions involved: traditional guidelines of high carbohydrate (CHO) availability for all training sessions; a periodized CHO diet which integrated sessions with low and high CHO availability within the same total CHO intake; and a ketogenic low-CHO high-fat diet. Seven-day menus and recipes were constructed for a communal eating setting to meet nutritional goals as well as individualized food preferences and special needs. Menus also included nutrition support before, during, and after exercise. Daily monitoring, via observation and food checklists, showed that energy and macronutrient targets were achieved. Diets were matched for energy (∼14.8MJ/d) and protein (∼2.1g·kg-1·day-1) and achieved desired differences for fat and CHO, with high CHO availability and periodized CHO availability: CHO = 8.5g·kg-1·day-1, 60% energy, fat = 20% of energy and low-CHO high-fat diet: 0.5g·kg-1·day-1 CHO, fat = 78% energy. There were no differences in micronutrient intake or density between the high CHO availability and periodized CHO availability diets; however, the micronutrient density of the low-CHO high-fat diet was significantly lower. Daily food costs per athlete were similar for each diet (∼AU$ 27 ± 10). Successful implementation and monitoring of dietary interventions in sports nutrition research of the scale of the present study require meticulous planning and the expertise of chefs and sports dietitians. Different approaches to sports nutrition support raise practical challenges around cost, micronutrient density, accommodation of special needs, and sustainability.

Disparity in the micronutrient content of diets high or low in advanced glycation end products (AGEs) does not explain changes in insulin sensitivity

We have previously shown that an isoenergetic low advanced glycation end products (AGEs) diet matched for macronutrient content improved insulin sensitivity compared to high AGE diet. Here, we evaluated the differences in micronutrient intake of these two dietary patterns and if they could explain differences in insulin sensitivity. Participants consumed the intervention diets each for 2 weeks with 4 weeks of habitual dietary intake (washout) in-between. Dietary analysis revealed that the high AGE diet contained greater levels of retinol equivalents (RE) (478.9 + 151.3 μg/day versus 329.0 + 170.0 μg/day; p < .006), vitamin A (806.3 + 223.5 (μg RE)/day versus 649.1 + 235.8 (μg RE)/day; p < .05) and thiamine (2.3 + 0.6 mg/day versus 1.6 + 0.4 mg/day; p = .014) compared to the low AGE diet. The changes in polyunsaturated fat, retinol, vitamin A and thiamine did not correlate with changes in insulin sensitivity (all p > .1) therefore are unlikely to explain observed changes in insulin sensitivity.

Dietary intake in people consuming a reduced-carbohydrate diet in the National Diet and Nutrition Survey.

Diets reduced or low in carbohydrates are becoming increasingly popular. The replacement foods and their accompanying nutrients determine the health effects of such diets. However, little is known about the dietary intake of people consuming reduced or low carbohydrate diets. In this cross-sectional study, the dietary and nutrient intake of individuals aged 16-75 years consuming less than 40% of energy from carbohydrate (n = 430) was compared with individuals consuming equal to or more than 40% energy from carbohydrate (n = 1833) using the UK National Diet and Nutrition Survey. Those consuming less than 40% of total energy from carbohydrate reported a higher consumption of red and processed meat, butter, oily fish and vegetables, as well as a lower consumption of soft drinks and pulses, than those with a normal carbohydrate intake. After adjusting for socio-economic status, only red meat intake was different between the groups, and reached the maximum recommended daily intake daily intake. There were no significant differences in micronutrient intakes between the groups, although magnesium, selenium and potassium, along with fibre, were lower than recommended amounts across the cohort. Individuals consuming reduced or low carbohydrate diets could benefit from replacing some red meats with white meats and vegetable sources of protein, and increasing vegetable intake.

Race/ethnicity-, gender- and age-specific differences in micronutrient intakes of US adults with and without diabetes

Race/ethnicity-, gender- and age-specific differences in dietary micronutrient intakes of US adults ≥ 21 years were assessed from National Health and Nutrition Examination Survey, 2007–2008. The participants included Black non-Hispanics, Mexican-American and White non-Hispanics who signed an informed consent form for the interview and who completed the in-person 24-h recall. Micronutrient intakes were based on the Institute of Medicines' classifications of recommended dietary allowances specific for age and gender. Likelihood of many micronutrient insufficiencies was associated with being female, over 65 years, having diabetes and minority status. Younger and female adults had a greater likelihood of iron insufficiency than male and older adults. These findings demonstrate the importance of considering the intersection of age, gender and race in setting policies for micronutrient deficiency screening, particularly in young female adults and minorities.

Is maternal education level associated with diet in 10-year-old children?

To examine the associations between maternal education level and diet in 10-year-old children. Three-day diet diaries (child completed with parental help) were collected. Height and weight were measured in research clinics. Maternal education level was derived from a questionnaire completed during pregnancy and classified into low, medium or high. One-way ANOVA was undertaken to compare maternal education groups for nutrient intakes and the Kruskal-Wallis test used for food consumption. Avon Longitudinal Study of Parents and Children (ALSPAC), Bristol, UK. Children (n 7474) who provided dietary data at age 10 years. A large proportion (60 %) of the sample was classified as plausible reporters, with under-reporting accounting for 36 %. No clear differences were found for intakes of energy or macronutrients between maternal education groups for plausible reporters. However, there were marked differences in micronutrient intakes especially for vitamin C, retinol equivalents and folate, highlighting lower diet quality with lower maternal education level. Intakes of fruit and vegetables showed a positive gradient with increasing maternal education (57 % v. 79 % consumed fresh fruit in low and high educational groups, respectively). A trend towards higher intake in the lower educated group was shown for less healthy foods (meat pies P < 0·001; sausages, burgers and kebabs P < 0·001). The quality of children's diet at 10 years was related to maternal education level. Lower maternal education was associated with less healthy food choices that could be detrimental to health. Further research is needed to establish if these associations can be explained by other socio-economic factors.

What do babies eat? Evaluation of a food frequency questionnaire to assess the diets of infants aged 12 months

To evaluate the relative validity of an FFQ for assessing nutrient intakes in 12-month-old infants. The FFQ was developed to assess the diets of infants born to women in the Southampton Women's Survey (SWS), a population-based survey of young women and their offspring. The energy and nutrient intakes obtained from an interviewer-administered FFQ were compared with those obtained from 4 d weighed diaries (WD). A sub-sample of fifty infants (aged 1 year) from the SWS had their diets assessed by both methods. The FFQ recorded the frequencies and amounts of foods and drinks consumed by the infants over the previous 28 d; milk consumption was recorded separately. The WD recorded the weights of all foods and drinks consumed by the infants on 4 d following the FFQ completion. The Spearman rank correlation coefficients for intakes of energy, macronutrients and eighteen micronutrients, determined by the two methods, ranged from r = 0.25 to 0.66. Bland-Altman statistics showed that mean differences between methods were in the range +5% to +60% except for vitamin D (+106%). Differences in micronutrient intake were partly explained by changes in patterns of milk consumption between the two assessments. Although there were differences in absolute energy and nutrient intakes between methods, there was reasonable agreement in the ranking of intakes. The FFQ is a useful tool for assessing energy and nutrient intakes of healthy infants aged around 12 months.

The contribution of specific dietary patterns to energy and nutrient intakes in 7–8‐year‐old Scottish schoolchildren. III. Snacking habits

The contribution of snacks to dietary intakes was investigated in a sample of 136 7–8‐year‐old children. Mean daily energy and nutrient intakes were estimated using the 7‐day weighed inventory method and the contribution of snacks was analysed separately. Snacks contributed 26% of energy intake and a large proportion of macronutrient intakes. The influence of a high intake of snacks on overall diet was investigated by classifying children as low or high snackers based on the proportion of daily energy intakes from snacks. There were no significant differences in anthropometry, and few significant differences in energy and nutrient intakes between children classified as ‘low’ and ‘high’ snackers. This was partly because ‘high’ snackers had a lower energy and macronutrient intake from meals, although this does not explain the lack of significant differences in micronutrient intakes between the snacking groups given that snacks were less nutrient dense than meals. It is concluded that snacks made an important contribution to energy and nutrient intakes in this sample but that further research is required to investigate how a high intake of snacks affects the quality of children's diets.

Ethnic Differences in Micronutrient Intake in a Rural Biethnic Population

Differences in micronutrient intake have been observed between populations of differing socioeconomic status (SES) and ethnicity. This study reports micronutrient intake among Hispanic and non-Hispanic white (NHW) persons in the rural San Luis Valley of southern Colorado. Current diet was assessed for a geographically based sample of 552 Hispanic and 754 NHW adults 30-74 years of age in two counties of rural southern Colorado (1984-1988). Diet was assessed by 24-hour recall. NHWs reported higher mean calorie intakes than Hispanics of both genders. NHWs had greater intakes of calcium, magnesium, potassium, phosphorus, riboflavin, niacin, zinc, vitamin A, and vitamin C than Hispanics, after accounting for ethnic differences in gender, age, and calorie intake. Differences in intake by gender were observed within and between ethnic groups. After adjusting for gender, age, ethnicity, and calories, we observed no statistically significant trends by SES measures. We conclude that diets of Hispanic adults would benefit from the addition of fresh fruits, vegetables, and high-calcium foods.

Dietary variety during and after pregnancy in Scotland and England

Interviews were carried out with 265 Scottish and English women from all social groups during and after pregnancy. Their consumption frequency of 123 food categories was elicited, with details of brands and types used. A simple ‘food groups’ concept of dietary variety did not differentiate any subgroup. When dietary variety was defined as numbers of different foods used within categories, the English ‘non‐manual’ group in early pregnancy ranked highest, and the Scottish ‘manual’ group lowest. During pregnancy about 30% of Scots and 25% of English reported a high consumption frequency of several processed foods. Generally, ‘fresh’ foods were more popular in England, and with the ‘non‐manual’ group. Regional and social class differences in dietary variety correspond broadly with differences in micronutrient intake and in knowledge of nutritional ‘messages’.
