Comparison in the dietary intake of preschool children, attending national daycare centres (Junji), in the eastern area of Santiago, Chile

The objective of this study was to evaluate the energy intake of obese and normal nutritional status preschoolers, from four to five years old, attending several day care centres (JUNJI), in the eastern area of Santiago. The sample comprised 85 normal nutritional status and 35 obese children, representative of a population of 450 children. The food intake was evaluated twice a week and on one weekend day. At the day care centre, food intake was measured by food weighing and at the home; it was measured by food-recording. FAO 2001 energy requirements were used to calculate the energy requirements of the children. In both obese and normal nutritional status, energy intake was similar in the educational institution and home, although this energy intake corresponds to there meals time at JUNJI and only one serving at home. In respect to energy requirements of preschool children, both obese and normal nutritional status boys are at energy balance during the week (90 versus 110%). In the corresponding female groups, energy intake exceeds their energy requirement (116 and 111% respectively). In conclusion, energy intake at home, is greater and of minor quality, situation that worsens over the weekend in all preschoolers, independently of their nutritional condition (energy adequacy > 114%).     

Food Insecurity and Associated Factors among HIV-infected individuals receiving highly active antiretroviral therapy in Jimma zone Southwest Ethiopia

ABSTRACT: BACKGROUND: In resource limited settings, many People Living with HIV/AIDS (PLWHA) lack access to sufficient quantities of nutritious foods, which poses additional challenges to the success of antiretroviral therapy (ART). Maintaining adequate food consumption and nutrient intake levels and meeting the special nutritional needs to cope up with the disease and the ART are critical for PLWHA to achieve the full benefit of such a treatment. OBJECTIVE: To determine the prevalence and correlates of food insecurity among HIV-infected individuals receiving highly active antiretroviral therapy in resource-limited settings. METHODS: A cross sectional study was carried out from January 1, 2009 to March 3, 2009 at ART clinic at Jimma University specialized hospital (JUSH) in Ethiopia. We used multivariable logistic regression model to compare independent risk factors by food insecurity status among 319 adult PLWHA ([greater than or equal to]18 years) attending ART Clinic. RESULTS: A total of 319 adult PLWHA participated in the study giving a response rate of 100%. Out of 319 PLWHA the largest numbers of participants, 46.4% were in the age group of 25-34 years. The overall 201(63.0%) PLWHA were food insecure. Educational status of elementary or lower [OR=3.10 (95%CI; (1.68-5.71)], average family monthly income <100 USD [OR=13.1 (95% CI; (4.29-40.0)] and lower food diversity [OR=2.18 (95%CI; (1.21--3.99)] were significantly and independently associated with food insecurity. CONCLUSION: Food insecurity is a significant problem among PLWHA on HAART. Lower educational status and low family income were the predictors of food insecurity. Food security interventions should be an integral component of HIV/AIDS care and support programs. Special attention need to be given to patients who have lower educational status and are members of households with low income. KEYWORDS: Food insecurity, HAART, PLWHA, HIV/AIDS, Ethiopia.     

Hospital food handlers in Niterói, RJ, Brazil: intestinal parasitism

A survey for intestinal parasites was carried out with food handlers from two private and three public hospitals in Niterói City, RJ, Brazil. The aim of this research was to verify the enteroparasites prevalence in this professional group. The investigation was divided in two phases. The first phase consisted of interviews with the participants; coproparasitological exams using Lutz, Faust et al. and Baermann techniques; under fingernail material analysis, using Mello et al. modified method; and educational lectures to food handlers. In the second phase, coproparasitological exams were repeated. Positive results were observed in 14.2% (17/120) and 17.1% (12/70) of the individuals in the first and second phases respectively. The most frequent parasite was Entamoeba coli, detected in 48.5% (16/33) of the samples with positive results. Under fingernail residues were observed in 19.2% (23/120) of the food handlers. E. coli cysts were found in one fingernail residue, likewise they were detected in the feces of the same food handler. Such data showed a potential transmission risk of intestinal parasites by food handling, indicating the need of adopting a diagnosis/orientation procedure as a bi-annual routine activity in hospitals, in order to improve the food service quality and population health condition.     

Niedersachsenstudie Krankenhauskost - Nährstoffrelation und Ballaststoffangebot der Vollkost in 70 Kliniken

Standard Diets in Hospitals - Comparison of Nutrient Intake with General Recommendations of Food Intake Standard diets provided by 70 hospitals were analysed for the following parameters (1) energy content, (2) per cent contribution of fat, protein and carbohydrates t o total energy administration, and (3) fibre content. Standard diets of all hospitals contained by far too much fat, while the content of carbohydrates and fibres was much too low compared with recommendations for an appropriate diet. The meal that differred most from the recommendations was dinner. Standard diets provided by hospitals should be in conformity with the dietary recommendations for the general population. We therefore suggest mandatory quality controls of hospital meals.     

Food and nutrition knowledge in Chilean high school graduates

The purpose of this study was to determine the degree of knowledge on food and nutrition in students graduating from high school in the Metropolitan Area of Santiago. The sample included 272 students of both sexes and type of school (public and private) and from high, medium and low socioeconomic level (SEL), measured through the Graffar Modified Scale. The degree of knowledge on food and nutrition was measured through a test of 48 items based on curriculum program objectives. The test covered three areas: Area 1, Food and Requirements; Area 2, Food, Personal and Environmental Hygiene, and Area 3, Nutritional Physiology. Students showed a good achievement of the food and nutrition objectives that are considered essential for obtaining and adequate nutrition and health status. Students from high SEL registered a significantly higher degree of knowledge on food and nutrition than students from other strata (p less than 0.001). However, sex and type of school had no effect on the degree of food and nutrition knowledge. This study is a contribution to the better understanding of factors affecting the food and nutrition knowledge, and provides good foundations for further studies.     

Food consumption patterns of children 4 to 14 years old in Valencia, Venezuela

Results from a nutritional assessment are presented to establish the usual food consumption pattern of 438 children between 4-14 years of age, from a low income urban community in Valencia, Venezuela. Food intake data were collected through multiple 24 hours recalls and converted to individual food item weight in grams. Amounts of energy, macronutrients, iron, calcium, vitamin A, and vitamin C were estimated to compare them to national references. The food pattern was established according to intake frequency per food item and per food groups. Arepa was the most commonly consumed food item, and a main source of kilocalories, protein, carbohydrates, iron, and vitamin A. Unlike coffee, fruits were not among the most commonly consumed foods. Black beans were the main source of protein. Cookies and sodas were among the major sources of energy. Energy and nutrient intake were adequate, except for calcium (67% in preschoolers y 43% in school-aged children). Preschoolers' diet showed a better adequacy for all nutrients (p < 0.005), except for iron which was significantly higher in school-aged children. Since children below 15 years old are still forming food behaviors and habits, they are an ideal group to develop nutritional education strategies to modify harmful patterns such as high intake of sodas, and low intakes of calcium rich foods.     

n−3 fatty acids and human health: Defining strategies for public policy

The last quarter of the 20th century was characterized by an increase in the consumer's interest in the nutritional aspects of health. As a result, governments began to develop dietary guidelines in addition to the traditional recommended dietary allowances, which have been superseded now by dietary reference intakes. In addition to governments, various scientific societies and nongovernmental organizations have issued their dietary advice to combat chronic diseases and obesity. Human beings evolved on a diet that was balanced in n?6 and n?3 essential fatty acid intake, whereas Western diets have a ratio of n?6/n?3 of 16.74. The scientific evidence is strong for decreasing the n?6 and increasing the n?3 intake to improve health throughout the life cycle. This paper discusses the reasons for this change and recommends the establishment of a nutrition and Food Policy, instead of a Food and Nutrition Policy, because the latter subordinates the nutritional aspects to the food policy aspects. Nutrition and food planning comprise a tool of nutrition and food policy, whose objectives are the achievement of the adequate nutrition of the population as defined by nutritional science. The scientific basis for the development of a public policy to develop dietary recommendations for essential fatty acids, including a balanced n?6/n?3 ratio is robust. What is needed is a scientific consensus, education of professionals and the public, the establishment of an agency on nutrition and food policy at the national level, and willingness of governments to institute changes. Education of the public is essential to demand changes in the food supply     

Food habits of high school graduates in the metropolitan area of Santiago, Chile

The purpose of this study was to determine the food habits of Chilean high-school graduates, and measure the effect that socioeconomic level (SEL), type of school (public and private school), sex and age exerts on those habits. A random and stratified sample of 283 schoolers, according to type of school, sex and SEL, measured through the Graffar Modified Scale was selected for the study. Food habits were defined by the frequency of consumption of food, expressed as days per week and were compared with the Model Allowance established by the Ministry of Health of Chile. A food habits questionnaire was administered to students by duly trained interviewers, and were defined by the frequency of consumption of food groups. Data were analyzed by the chi-square procedure, analysis of variance and Student's "t" test. In accordance with the results, the most consumed foods (over 90% of students) were meat, poultry, eggs, potatoes, apples, bread, rice, oil and butter or margarine. On the other hand, the most disliked foods (40% and more of students) were fresh cheese, viscera, radish and chickpeas. The high SEL students showed a significantly greater frequency of consumption of dairy products, and of meat products and eggs (p less than 0.001). No differences were found according to type of school, sex and age of students. We conclude, therefore, that SEL exerts a significant effect on food habits, in spite of which they were adequate according to the Model Allowance.     

Food group intake patterns and nutrient intake vary across low-income Hispanic and African American preschool children in Atlanta: a cross sectional study

ABSTRACT: BACKGROUND: The food group intake patterns of low income Hispanic and African American preschool children are not well documented. The aim of this study was to perform a food group intake analysis of low income minority preschool children and evaluate how macronutrient and micronutrient intake compares to Dietary Reference Intakes (DRI). METHODS: A cross sectional study design using three-day food diaries analyzed by dietary analysis software (Nutrient Database System for Research) was used. Children were recruited from well-child clinics at Children's Healthcare of Atlanta at Hughes Spalding and North Dekalb Grady Satellite Clinic, Atlanta, GA. Low-income, African American and Hispanic preschool age children (n = 291) were enrolled. A total of 105 completed the 3-day food diaries were returned and analyzed. Chi-squared tests were used to assess demographic variables. The mean percentage of intake per day of specific food groups and sub-groups were obtained (servings of given food group/total daily servings). Food intake data and proportion of children meeting DRIs for macro- and micronutrients were stratified by race/ethnicity, nutritional status, and caloric intake, and were compared using t-tests. Regression models controlling for age, BMI and sex were obtained to assess the effect of total caloric intake upon the proportional intake of each studied food group. RESULTS: The mean age of African American children was 2.24 [PLUS-MINUS SIGN] 1.07 years and Hispanic children 2.84 [PLUS-MINUS SIGN] 1.12 years. African Americans consumed more kcal/kg/day than Hispanics (124.7 [PLUS-MINUS SIGN] 51 vs. 96.9 [PLUS-MINUS SIGN] 33, p < 0.05). Hispanics consumed more fruits (22.0 [PLUS-MINUS SIGN] 10.7% vs. 14.7 [PLUS-MINUS SIGN] 13.7%, p < 0.05), while African Americans consumed more grains (25.7 [PLUS-MINUS SIGN] 7.8% vs. 18.1 [PLUS-MINUS SIGN] 6.4%, p < 0.05), meats (20.7 [PLUS-MINUS SIGN] 9.0% vs. 15.4 [PLUS-MINUS SIGN] 6.1%, p < 0.05), fats (9.8 [PLUS-MINUS SIGN] 5.4% vs. 7.0 [PLUS-MINUS SIGN] 5.8%, p < 0.05), sweet drinks (58.7 [PLUS-MINUS SIGN] 17.1% vs. 41.3 [PLUS-MINUS SIGN] 14.8%, p < 0.05) and low-fat dairy products (39.5 [PLUS-MINUS SIGN] 19.3% vs. 28.9 [PLUS-MINUS SIGN] 12.6%, p < 0.05). Among Hispanics, the proportional intake of fruits, fats and grains varied by total caloric intake, while no difference by total caloric intake was found for the dietary patterns of African Americans. Micronutrient intake also differed significantly between African American and Hispanic children. CONCLUSIONS: Food group intake patterns among low-income children differ by ethnic group. There is a need for more research to guide program design and target nutritional interventions for this population.     

Food habits and caries experience in young adults from Rosario, Argentina

Odontological assistance in Rosary City is offered in private and public services. The public ones lack programs to avoid dental loss in adults. Our aim was to describe the caries experience and dietetic habits in three sub-populations of young adults. Applying a standardized anamnesis, 517 patients, both sexes, 15-45 years old, attending to a private service (19%) and two public ones (81%), were investigated. Studied variables: oral health, lacteal and sweet food consumed, and instruction level. Student t-test, ANOVA and chi-square tests were applied. Average decayed teeth were 1.7+/-2.0 in the private service, and 4.1+/-2.8 in the public ones (p<0.0001); missing teeth were 5.4+/-5.2 and 6.8+/-5.4 (p=0.04); and filled teeth were 4.4+/-4.2 and 1.3+/-2.2, respectively (p<0.0001). Dairy foods daily consumption was higher in the private service (p<0.001). Patients in the public services expressed to replace milk by mate, and to relate its consumption with pregnancy and lactation, or to leave it for children. Sweets delicacies consumed in the private sector -considered of risk- were sweet breads, cakes, cookies and sweets, and in the public ones were soft candies, "alfajores" and sweet made with milk. Minor risk sweets consumption in private patients were ice creams, sodas and chocolates, and in the public ones, hard candies and chewing gums, with and without sugar. Although a high number of patients consume delicacies and sweet foods at any hour, private patients were a minority; and they were a majority when considering its ingestion only after a food.     

Food and nutrition knowledge of students graduating from basic education in the metropolitan area of Santiago, Chile

The aim of this study was to evaluate the degree of knowledge on food and nutrition in students graduating from Basic Education in the Metropolitan Area of Santiago, Chile. A random sample of 249 students of both sexes (1:1) from public and non-public schools (1:1) and from high, medium and low socioeconomic level (SEL), was selected. SEL was measured through the Graffar Modified Scale, and the degree of knowledge on food and nutrition was evaluated through a standardized test of 29 multiple choice items, based on the objectives of the curriculum program. The test was divided in two areas: Area 1, which contemplated Food and Requirements and Area 2, Food, Personal and Environmental Hygiene. Data were analyzed by chi-square procedure, comparing students who obtained sufficient knowledge (greater than or equal to 50% of correct answers) with those who obtained insufficient knowledge (less than 50% of correct answers). Results of the study indicated that 39.8% of students registered sufficient knowledge, 31.3% and 65.9% in Area 1 and 2, respectively. According to SEL, 62.1% and 12.3% of students from high and low SEL, respectively, registered sufficient knowledge (p less than 0.001), and the same effect was observed in Areas 1 and 2. In relation to sex, 46.3% of females and 33.3% of males registered sufficient knowledge (p less than 0.05), fact which was confirmed in both areas of the test. No significant differences were registered in the degree of knowledge on food and nutrition of students from public and non-public schools. It is therefore concluded that the degree of knowledge on food and nutrition in students graduating from Basic Education differs significantly according to SEL and, sex. This study represents a basic contribution to the better understanding of factors affecting the degree of knowledge on food and nutrition in students graduating from Basic Education in Santiago, Chile, and may serve as base-line for further studies on the subject.     

Ozone Processing for Food Preservation: An Overview on Fruit Juice Treatments

This paper reviews the efficacy of ozone an emerging non-thermal food preservation technique for fruit juices and highlights changes in key microbial, quality and nutritional parameters. Ozonation of fruit juices has been identified as a potential technology to meet the United States Food and Drug Administration's requirement of a 5 log reduction in pertinent microorganisms found in juices. This review suggests that it is important to identify the critical extrinsic and intrinsic control parameters governing both the efficacy and quality effects during ozonation of fruit juices.

Food powders engineering, between knowhow and science: Constraints, stakes and opportunities

Food powders are presented and discussed according to food sciences specificities and according to powder engineering concepts. Food powders are very present in everyday life. They are generally obtained from agricultural raw materials by different processes such as fragmentation or spray-drying processes. Amongst the food products, the food powders are easy to preserve, transport, store, weight and process. They are used to bring specific functionalities (e.g. physicochemical stability, microbiological stability, organoleptic qualities and nutritional composition). As well as food products, food powders are complex systems that can be defined by a great dispersion in their properties caused by: (i) the complexity of the chemical composition of the agricultural raw materials; (ii) the heterogeneity of the native structures of the product; (iii) the reactivity under high temperature or water addition; (iv) the variability of the agricultural raw materials behavior. Food companies, equipment suppliers, and scientists became aware of the relevance of a global approach by integrating the food powders engineering approach (particles properties, powder reactivity, and powder processing) to the classical food sciences concepts. The aim of this article is to highlight the stakes and opportunities concerning food powder processing and particles properties.     

LATINFOODS

Food Composition Tables should be considered as national wealth and as valuable tools for utilization in food and nutrition, in nutritional therapy, in agricultural planning and production, in food guides, and in the food industry for the formulation of information on the product that appears in the label. They should, therefore, be considered as national wealth because they chemically describe the food resources of a country at a very high price, and are considered valuable tools due to their multiple applications. The countries present Tables were published between 1935 and 1961, with analytical data available at that time. So far the Tables have met their purpose, but due to changes that have occurred in raw materials, in analytical methodology, in the new knowledge acquired in nutrition, and in the relationships between food and diseases, in November 1986, representative groups of the Latin American and the Caribbean countries decided to create LATINFOODS. The objective of the program is to promote the development of data banks of foods of the Latin American countries, creating national multidisciplinary groups interested in data production, compilement, publication and utilization, and that eventually, may be homogeneously united to form a data bank for Latin America and the Caribbean Region. During the meeting in favor of the creation of LATINFOODS, detection was made of the constraints of the Food Composition Tables now used as well as the measures needed to correct such problems. These included the number of samples collected as well as the analytical methods used, and the number of nutrients. Due to the observed increase in production and distribution of new food products by the food industry, and to the increased association between foods and diseases, the food industry must participate not only in the generation of data, but in their utilization for food identification, nutrient contribution and nutritional education. Likewise, academic programs in Food Technology should extend the concepts of Food Science with special emphasis on food nutrient contents, to reach an adequate nutritional and health status for the Latin American population.     

Nutritional value of rapeseed oil and its high oleic/low linolenic variety – A call for differentiation

To offer the best choice of healthy and acceptable food to the consumer a coordination of plant breeding, food processing and nutrition science is required. Here the nutritional aspects of the high oleic/low linolenic (HOLLi) varieties of rapeseed with a low α‐linolenic acid content of about 3% are reviewed. The content of α‐linolenic acid amounting to around 9% is the hallmark of the positive nutritional value of the original (erucic acid free) 00 varieties of rapeseed oil (“canola” quality in North America). n‐3 fatty acids are endowed with the property to protect the cardiovascular system from chronic disease and the consumption of food containing n‐3 fatty acids is explicitly recommended by national and international nutritional and medical authorities. Although the use of HOLLi with a low n‐3 fatty acid content can be unavoidable for specific purposes, because of technological and health considerations the continuous future consumption of the original rapeseed oil with around 9% of α‐linolenic acid by the consumer should have high priority from the standpoint of public health. To pursue this aim confusion of the consumer must be avoided by creating a new name and a new brand for HOLLi varieties.     

Social cost effectiveness of 2 systems of treatment of malnourished children, in Chile

Two approaches in the care of malnourished children were evaluated in order to ascertain both their medical and economical effectiveness. One was a group of 745 children under an ambulatory nutritional rehabilitation program that included health care, supplementary foods and nutrition education; a second group of 420 children attended Day Care Centers (8 hours a day and five days per week) where they received a balanced diet, psychomotor stimulation according to age, and health care. The evolution of nutritional status was followed up and plotted against the NCHS/WHO weight-for-height tables. The rate of recovery was unsatisfactory; below 50% in mild cases of malnutrition, and even less in the more severe cases. The average length of time for attaining normality was longer for moderate malnutrition and for the ambulatory program. When the calculation included a correction for the probability of recovery for each system, the advantage of the Day Care Centers became even more evident: the mean length of time for recovery was 33.2% less than the ambulatory program. The social cost per child, per day, was substantially lower in the ambulatory program. The integral calculus of social cost per child, per day, and the corrected mean time for recovery provided the social cost-effectiveness of nutritional recovery. This figure was clearly adventageous for the ambulatory program for all ages and degrees of malnutrition, exception made for moderately malnourished children below two years of age. In this case, the Day Care Centers appeared to be the most effective therapeutic alternative. This type of analysis is a contribution to the evaluation of medico-social programs for the recuperation of malnutrition. The advantage lies in the fact that it allows an optimization in the allocation of resources, when the previous step is the choice of best therapeutic alternative based upon the patient's age and nutritional status.     

Development of a food frequency questionnaire for Sri Lankan adults

ABSTRACT: BACKGROUND: Food Frequency Questionnaires (FFQs) are commonly used in epidemiologic studies to assess long-term nutritional exposure. Because of wide variations in dietary habits in different countries, a FFQ must be developed to suit the specific population. Sri Lanka is undergoing nutritional transition and diet-related chronic diseases are emerging as an important health problem. Currently, no FFQ has been developed for Sri Lankan adults. In this study, we developed a FFQ to assess the regular dietary intake of Sri Lankan adults. METHODS: A nationally representative sample of 600 adults was selected by a multi-stage random cluster sampling technique and dietary intake was assessed by random 24-h dietary recall. Nutrient analysis of the FFQ required the selection of foods, development of recipes and application of these to cooked foods to develop a nutrient database. We constructed a comprehensive food list with the units of measurement. A stepwise regression method was used to identify foods contributing to a cumulative 90% of variance to total energy and macronutrients. In addition, a series of photographs were included. RESULTS: We obtained dietary data from 482 participants and 312 different food items were recorded. Nutritionists grouped similar food items which resulted in a total of 178 items. After performing step-wise multiple regression, 93 foods explained 90% of the variance for total energy intake, carbohydrates, protein, total fat and dietary fibre. Finally, 90 food items and 12 photographs were selected. CONCLUSION: We developed a FFQ and the related nutrient composition database for Sri Lankan adults. Culturally specific dietary tools are central to capturing the role of diet in risk for chronic disease in Sri Lanka. The next step will involve the verification of FFQ reproducibility and validity.
