Sterile soil mitigates the intergenerational loss of gut microbial diversity and anxiety-like behavior induced by antibiotics in mice

The decline in gut microbial diversity in modern humans is closely associated with the rising prevalence of various diseases. It is imperative to investigate the underlying causes of gut microbial loss and restoring methods. Although the impact of non-perinatal antibiotic use on gut microbiota has been recognized, its intergenerational effects remain unexplored. Our previous research has highlighted soil in the farm environment as a key factor for gut microbiome health by restoring gut microbial diversity and balance. In this study, we investigated the intergenerational consequences of antibiotic exposure and the therapeutic potential of sterile soil. We treated C57BL/6 mice with vancomycin and streptomycin for 2 weeks continuously, followed by a 4-8 week withdrawal period before breeding. The process was repeated across 3 generations. Half of the mice in each generation received an oral sterile soil intervention. We assessed gut microbial diversity, anxiety behavior, microglial reactivity, and gut barrier integrity across generations. Antibiotic exposure led to a decrease in gut microbial diversity over generations, along with aggravated anxiety behavior, microgliosis, and altered intestinal tight junction protein expression. Oral sterile soil intervention restored gut microbial diversity in adult mice across generations, concomitantly rescuing abnormalities in behavior, microgliosis, and intestinal barrier integrity. In conclusion, this study simulated an important process of the progressive loss of gut microbiota diversity in modern humans and demonstrated the potential of sterile soil to reverse this process. This study provides a theoretical and experimental basis for research and interventions targeting multiple modern chronic diseases related to intestinal microorganisms.

Nutritional Status and Associated Risk Factors of Syrian Children's Residents in the Kingdom of Saudi Arabia

This study aimed to evaluate the nutritional status and associated risk factors of Syrian children living in Saudi Arabia. In this study, 55 boys and 55 girls ranging in age from 6 to 12 years were selected. Socioeconomic data of families were collected using a structured questionnaire. The participants' anthropometric measurements were calculated. The 24-h recall method was applied to calculate the daily food intake. Dietary nutrients' average daily intake of both boys and girls was significantly (p ≤ 0.01) lower than that of the dietary reference intake (DRI) with few exceptions. The sedentary lifestyles of both boys and girls had a negative impact on their food choices, and as a result, a large number of them were underweight and suffered from malnutrition and stunting. Spearman correlation coefficients revealed that most of the children's dependent variables were risk factors and strongly and negatively associated with their nutritional status proxies. The study concluded that both boys and girls had unbalanced nutritional status with high percentages of malnutrition and stunting because most dependent factors were adversely related to the independent ones.

Increasing activity and improving nutrition through a schools-based programme: Project Energize. 1. Design, programme, randomisation and evaluation methodology

Project Energize is a through-school nutrition and activity programme that is being evaluated in a 2-year, cluster-randomised, longitudinal study. The present paper describes the background of the programme and study, the programme development and delivery, the study methodology including randomisation, measurement and analysis tools and techniques, and the mix of the study population. The programme is being delivered to sixty-two primary schools with sixty-two control schools, each limb containing about 11 000 students. The children in the evaluation cohort are 5 or 10 years old at enrolment; the randomisation protocol has achieved post-consent enrolment of 3000 evaluation participants, who are comparable by age, sex and school decile. End-point measures include body composition and associated physical characteristics, fitness, home and school environment and practice.

An overview of pediatric obesity

Pediatric obesity is increasing worldwide and disproportionately affects the economically and socially disadvantaged. Obese children are at risk of developing the (dys)metabolic syndrome, insulin resistance, early-onset type 2 diabetes mellitus, polycystic ovarian syndrome, hypertension, hyperlipidemia, and obstructive sleep apnoea. Those with diabetes may have mixed features of type 1 and type 2 diabetes mellitus. Pediatric obesity is the result of persistent adverse changes in food intake, lifestyle, and energy expenditure. It may be because of underlying a genetic syndrome or a conduct disorder. Children living in urban settings often lack safe, affordable, and accessible recreational facilities. Tight educational schedules mean less free time, while computer games and television have become preferred recreational activities. More families are eating out or eating take-out meals and processed foods at home because of pressures of work and time constraints. Consumer advertising targeted at children and the ready availability of vending machines encourage unwise food choices. Some children eat excessively because they are depressed, anxious, sad, or lonely. Often families and obese children are aware of the need for healthy eating and exercise but are unable to translate knowledge into weight loss. Population-based measures such as public education, school meal reforms, child-safe exercise friendly environments, and school-based and community-based exercise programs have been shown to be successful to varying degrees, but there remain individuals who will need special help to overcome obesity. Overeating (e.g. binge eating) may be a manifestation of disordered coping behavior but may also be because of defects in the neural and hormonal control of appetite and satiety. New pharmacological approaches are targeting these areas. We need a coordinated approach involving government, communities, and healthcare providers to provide a continuum of population-based interventions, focused screening, and personalized multidisciplinary interventions for the obese child and family.

Adição da vitamina E aos alimentos: implicações para os alimentos e para a saúde humana

A ingestão de vitamina E em doses acima das estabelecidas pelas Dietary Reference Intake, na forma de alimentos ou suplementos, está relacionada à prevenção de doenças crônicas não transmissíveis, à estimulação do sistema imune e à modulação dos processos degenerativos relacionados ao envelhecimento. Por outro lado, a adição de vitamina E aos alimentos com o intuito de alcançar tais efeitos ainda não é comum, porque não há consenso sobre a dose a ser consumida. Em muitas populações tem sido necessário ingerir alimentos fortificados com vitamina E, para alcançar os níveis recomendados para a ingestão adequada. Este trabalho enfoca o papel da vitamina E como um componente antioxidante utilizado pela indústria alimentícia, como um composto que exerce funções específicas no organismo humano e no alimento e como um importante nutriente que, quando adicionado aos alimentos, é capaz de atuar contra a lipoperoxidação e contribuir para o aumento de sua ingestão, além de poder reduzir os efeitos deletérios dos processos oxidativos que ocorrem no organismo humano, prevenindo as doenças crônicas não transmissíveis.

Energy, macro- and micronutrient intake among a true longitudinal group of South African adolescents at two interceptions (2000 and 2003): the Birth-to-Twenty (Bt20) Study

OBJECTIVE

This study reports on the energy, macro- and micronutrient intakes of a true longitudinal group of 143 urban black South African children from the Birth-to-Twenty (Bt20) study at two interceptions (2000 and 2003) when they were 10 and 13 years old, respectively.

METHODS

Subjects resided in the urban Johannesburg/Soweto area of the Gauteng Province in South Africa. Dietary intake was assessed using a semi-quantitative food-frequency questionnaire. The coded data were analysed using SAS.

RESULTS

Mean daily intake of energy, all six macronutrients and most micronutrients (17/19) increased from 2000 to 2003. Of the 19 micronutrients investigated, the mean daily intake of eight (calcium, iron, zinc, vitamin A, riboflavin, nicotinic acid, pantothenic acid and biotin) fell below the recommended dietary allowance (RDA) at both interceptions. More than 70% of the children consumed less than the RDA for these same eight nutrients. From 2000 to 2003, there was a decrease in the percentage of children falling below the RDA for energy (from 73 to 59%), but an increase in the percentage of children falling below the RDA for most of the micronutrients. There was a positive percentage change in mean daily intake for all 26 macro- and micronutrients from 2000 to 2003.

CONCLUSION

Mean daily intake of nutrients increased from 2000 to 2003, but intakes for most micronutrients were still below the RDA at both interceptions for a large percentage of the children. The study has provided valuable information on the nutrient intake and change in intake over time among a longitudinal group of South African adolescents.

Nutrition risk in the child and adolescent population of the Basque country: the enKid Study

Cross-sectional population studies provide valuable information for nutrition surveillance and planning intervention strategies. The enKid Study is the largest nutrition survey on the child and adolescent Spanish population to date. In the present paper, nutrition risks in children and young people of the Basque country based on the enKid Study subsample for the Basque region are presented. Dietary assessment was completed by means of a 24 h recall and a food frequency questionnaire completed in an interview with the mother or caregiver for children under 13 years. A second 24 h recall was completed on 25 % of the sample. Body weight, height and circumference were measured on each individual. Overweight and obesity were defined using Coleet al.cut-offs. Fat intake supplied 40 % of energy intake and saturated fats 13·8 %. Overall, 80 % of the sample had intakes of fat above 35 %. Main food sources of fats were added fats (32 %), meat (20 %) and milk products (20 %). Buns, cakes and pastry supplied 11 % of total fat intake. The nutrients showing the highest proportion of people who did not reach one third (33 %) of the Spanish dietary reference intake levels were vitamin D, vitamin E, vitamin A and folate. Prevailing food pattern showed a high consumption of meat and meat products, milk, dairy products and cereals. Conversely, consumption of fruit, vegetables and fish was low; in fact, 89 % of the sample had a normal consumption of fruit and vegetables below five portions a day. Prevalence of obesity was estimated at 3·94 %, and 17·85 % of the sample was classified as overweight.

Dietary intake in asylum seeker children in The Netherlands, strongly related to age and origin

OBJECTIVE

To monitor the dietary intake of energy, macro- and micronutrients in asylum seeker children.

DESIGN AND SETTING

Cross-sectional study in three asylum seeker centres in The Netherlands.

SUBJECTS

Hundred and sixteen children 2-12 years old (86% of the study cohort) provided a dietary history.

METHOD

The dietary intake was estimated by 24 h recall, and the origin of the children was classified in three geographic regions: African (n=45), Central Asia (n=34) or Eastern Europe (n=37).

RESULTS

The total energy intake from fat was in 24% of the children above 40En%. Seventy per cent of the children above 4 year of age had a saturated fat intake above 10En%. The children from Eastern Europe had a higher intake of fat and disaccharides than the children from the other regions. Among the children, an intake less than 80% of the recommended daily allowances of micronutrients was found for calcium (42%), iron (49%), vitamin A (45%) and vitamin D (80%). An inadequate dietary intake of iron and vitamin D was significantly more seen among the youngest children, whereas an inadequate intake of calcium and vitamin A was found more among the elder children.

CONCLUSIONS

The dietary intake of a prominent proportion of these children contains too much fat and insufficient amounts of calcium, iron, vitamin A and vitamin D. The low micronutrient intake of the asylum seeker children can be considered as a nutritional risk. Nutritional education and strategies to improve the macro- and micronutrient intake of asylum seeker children is indicated.

Frequency of food items consumed by young rural and urban African children--essential knowledge to provide dietary advice in caries prevention

AIMS

To determine the variety and frequency of consumption of food items, including cariogenic items, among 4-24-month-old black South African children.

SETTING AND PARTICIPANTS

A rural area of low socioeconomic status, Ndunakazi, KwaZulu/Natal Province [n=105]; two urban areas in Gauteng Province: Soweto (low to middle socioeconomic status) [n=100], and the northern suburbs of Johannesburg and Sandton (middle to upper socioeconomic status) [n=101].

METHODS

Dietary intake was assessed using a food frequency questionnaire and analysed using SAS.

OUTCOME MEASURES

Weekly frequencies for: number of times each food item was recorded; total consumption for each food item for the combined group of children and the three individual geographical areas. Food items were ranked in descending order according to the combined group of children within five selected food groups (carbohydrates, sugars, fruit and vegetables, milk and milk products, other foods and snacks). Only individual area results were listed.

RESULTS

The preferred foods and frequency of consumption of these foods were identified. Significant differences were found between rural and urban groups for most of the food items, but not between urban groups. Food items were 'flagged' according to their cariogenic potential.

CONCLUSION

The study provided valuable new information suitable for adapting and developing dietary advice relevant to caries prevention in African children

Within- and between-person variation in nutrient intakes of Russian and U.S. children differs by sex and age

Within- and between-person variation in nutrient intake has been characterized in different adult populations, but little is known of country, age, or sex differences among children. The objectives of this study were as follows: 1) to describe the mean intake, within- and between-individual CV and variance ratios of nutrient intake among children ages 9-18 y old in Russia and the United States in 1996; 2) to compare the age and sex-related differences in nutrient intake variance within and between countries; and 3) to hypothesize about the feasibility of using within-individual variance estimates from one nationally representative sample to adjust the usual intake distributions in another nationally representative sample. Mean intakes of all nutrients except magnesium were significantly higher among U.S. children (P < 0.001); within-person variation was higher among the U.S. children, possibly indicating greater access to a wide array of foods. Strong differentials existed in variance components by sex in both countries, although not in the same direction, and differed by age in U.S. girls. Ratios of within- to between-person variance in 8 of 11 nutrients were lower among Russian (range: 0.9-1.6) than U.S. children (range: 1.4-1.7), suggesting that day-to-day bias may not affect Russian dietary recalls as strongly as in the United States. Researchers are encouraged to use these estimates to conduct sensitivity analyses of usual intake distributions in their own data when multiple days of data collection are not feasible.

Helping to promote healthy diets and lifestyles: the role of the food industry

In order to be successful, public health nutrition strategies require the active collaboration of all stakeholders in the promotion of healthy diet and lifestyle patterns. The food industry plays an important role both in providing products that meet consumers' needs in terms of taste, convenience, quality, nutrition and value as well as in communicating to consumers about the importance of good nutrition, including the contribution of specific foods to a balanced diet. The food industry contributes to educational efforts regarding healthy diets and lifestyles both directly--through product labelling, advertising, educational materials, on-line communications and information provided by Consumer Services departments--and indirectly, through active involvement and participation in educational programmes pursued in collaboration with nutrition and health education authorities. Through ongoing dialogue with its consumers and research conducted on consumer knowledge and attitudes towards diet, the food industry can ensure that communications developed are motivating and relevant to consumers' lives. In this paper, the specific contribution of the food industry will be illustrated through the promotion of healthy eating habits among children, focusing in particular on the importance of the breakfast meal.
