Assessment of the nutritional quality of some selected ethnic foods consumed in Italy was performed within the framework of the European Food Information Resource (EuroFIR 1 ) Network as part of the ethnic foods Work Package. A definition of ethnic and modified ethnic foods, as well as guidelines on the characterisation of immigrant populations and a detailed stepwise analysis of the ethnic food market, have been developed within the EuroFIR project. These were the basis for selecting ethnic foods in Italy for nutritional analysis. Four main immigrant groups (Asian, Latin American, African and Eastern European) were identified as commonly selected from those residing in Italy, and 25 dishes or composite foods consumed by these ethnic groups were selected. Based on consumption rates and market share of these foods in Italy, five ethnic food types (cantonese rice, nachos, falafel, kebab, sarmale) were chosen and collected for analysis. Nutritional evaluation of the selected foods was performed by analysing the following components: water, nitrogen, fat, total sugars, starch, total ash and dietary fibre, fatty acid composition, cholesterol, minerals (Na, Ca, Fe, P, Mg, K, Cu, S, Zn and Cl), and vitamins (vitamins A, E, B1, B2, B6, C, biotin, niacin and β‐carotene). Procedures for collection of the chosen foods, along with the results of the analysis, are described in the present paper. These new data will be added to the Italian Food Composition Tables.  相似文献

Dietary deficiency in iron and to a lesser extent folic acid is the principle cause of anemia in the world. Reproductive aged women and growing children are the principle groups at risk of anemia. About half of nonpregnant reproductive aged women in tropical countries have hemoglobin levels lower than 12 g/100 ml, the level used by the World Health Organization to define anemia. Nutritional anemia is even more widespread among pregnant and lactating women because of the increased needs for iron during those periods. Pregnant women need almost 500 mg of iron for their increased red blood cell mass, 220 mg for routine iron loss through the urine, bile, sweat, and other routes; 290 mg for the fetus, and almost 25 mg for the placenta. In all, the pregnant women theoretically requires over 1000 mg of iron through diet or bodily reserves. Healthy, well-nourished women have total iron reserves of 2500 mg, but according to published data almost 2/3 of pregnant women even in favorable circumstances end their pregnancies with no remaining iron reserves. In tropical regions the lack of iron reserves is aggravated by parasites and infections, closely spaced pregnancies that do not allow restoration of reserves, and poor dietary availability of iron. Anemia during pregnancy is associated with elevated risks of maternal morbidity and mortality. Fatigue, dyspnea, palpitations and tachycardia, vertigo, loss of appetite and cravings for soil or other inappropriate substances are frequently observed in anemic women. The risks of prematurity and low weight are increased for infants of anemic women. Fetal malformation may be associated with folic acid deficiency. Nutrition education is needed for pregnant women. Local foods may be enriched with iron, and pregnant women may be given iron and vitamin B12 supplements directly. Iron supplements may rapidly increase iron reserves, but they are poorly tolerated by many women. The supplements should be avoided if possible early in the pregnancy because digestive intolerance is more likely in the 1st months of pregnancy. Parasitic and bacterial infections should be diagnosed and treated as a step in controlling anemia.  相似文献

ABSTRACT: BACKGROUND: Chronic diseases are the leading cause of premature death and disability in the world with over-nutrition a primary cause of diet-related ill health. Excess quantities of energy, saturated fat, sugar and salt derived from fast foods contribute importantly to this disease burden. Our objective is to collate and compare nutrient composition data for fast foods as a means of supporting improvements in product formulation. Methods/design Surveys of fast foods will be done in each participating country each year. Information on the nutrient composition for each product will be sought either through direct chemical analysis, from fast food companies, in-store materials or from company websites. Foods will be categorized into major groups for the primary analyses which will compare mean levels of saturated fat, sugar, sodium, energy and serving size at baseline and over time. Countries currently involved include Australia, New Zealand, France, UK, USA, India, Spain, China and Canada, with more anticipated to follow. DISCUSSION: This collaborative approach to the collation and sharing of data will enable low-cost tracking of fast food composition around the world. This project represents a significant step forward in the objective and transparent monitoring of industry and government commitments to improve the quality of fast foods.  相似文献

The diet of mothers during pregnancy and lactation has a direct influence on her infant's health status. A study was conducted in India's Udaipur region to learn more about the nutritional content of supplementary foods consumed by mothers during the 1st 3 months of lactation. A food consumption survey revealed that 6 different supplementary food items--ajwain ka laddu, gond ka laddu, battia ka laddu, haldi laddu, lidh ka laddu, and soth ka laddu--were widely consumed by lactating women in ball form. A nutritional analysis of these supplementary foods indicated that a 250-gram serving is sufficient for meeting a third of the protein and carbohydrate requirements of a lactating woman. All foods analyzed were rich sources of iron, calcium, phosphorus, and magnesium. Of all the forms of laddu, ajwain contained the maximum amount of protein, calcium, phosphorus, and moisture while battia provided the most iron. The fat content was generally high in all cases to enable the ingredients to be formed into balls. It appears that the diet of lactating women is given greater attention in the immediate postpartum period than in is in later stages of lactation.  相似文献

46 of 74 children with chronic diarrhea of unknown etiology between the ages of 44-627 days were studies. They were assigned, by single randomization, to 3 dietary treatments: a) cow's milk, b) a sucrose- free (SED-S), and c) a sucrose containiNG semi-element diet (SED+S), for 15 days. The authors registered the daily increase of body weight, daily amount of ingested kcal, and the increase of body weight/1000 kcal. The number of days with diarrhea before hospitalization, the age and weight of each child before treatment were recorded and analyzed as covariates. Maltase, sucrase, and lactase activity values were compared before treatment, but were not different among the 3 groups. A significant increase of body weight/1000 kcal ingested was observed in children fed the SED-S diet compared to that observed in children on cow's milk (P=.013 in ANCOVA; P+.053 in RANCOVA), and those fed SED+S (P=.009 in Ancova; p.001 in RANCOVA). The covariates did not have any apparent effect on these results. Only 7 of 24 children receiving cow's milk completed the assigned diet. The carbohydrate composition of the semi-elemental diets proved to be fundamental in the nutritional recovery of these patients.  相似文献

Objectives

To assess body composition, nutritional status and its differences between genders in a sample of Portuguese centenarians.

Design

Observational cross-sectional study.

Setting

Centenarians recruited in Portugal, able to give informed consent.

Participants

A total of 252 subjects, with a median age of 100 years, mostly women (77.8%) who accepted to participate in the study, during the period of 2012 to 2014.

Measurements

Anthropometric data collected (weight, height, BMI, waist circumference, hip and waist/hip ratio) were evaluated according to WHO criteria. A portable tetrapolar bioimpedance analyzer was used to calculate body composition and to assess resting metabolism. Nutritional status was evaluated according to three different criteria: BMI, waist circumference and body fat percentage using anthropometric equations and bioimpedance.

Results

We observed an overall mean weight of 51.02±11.03Kg, height of 1.55±0.07m and a BMI of 21.07±3.69Kg/m2. For most of the evaluated parameters, we found substantial differences between genders. The prevalence of underweight and overweight were 25.3% and 13.3%, respectively. Only 5 subjects were obese. Overweight subjects were mostly men (W=10.6% vs. M=22.6%), whereas women were more underweight (W=28.7% vs. M=13.2%). When considering the waist circumference, 26.5% were above the cut-off value. Most of centenarians (72.9%) had a healthy level of visceral fat. This measurement was highly correlated with waist circumference (r= 0.687, p<0.001). The mean of body fat mass was 10.69±6.50Kg, fat-free mass 40.87±7.60Kg and total body water 27.54±6.25Kg. According to body fat mass criteria assessed by bioimpedance, the prevalence of obesity in study population was 6.0% with no gender differences (p = 0.225). Obesity prevalence using anthropometric equations was higher (Deurenberg: 77.7% and Gallagher: 42.8%) than the obtained value by bioimpedance analysis, although according to Bland-Altman analysis both equations showed a good agreement (Deurenberg: 95.8% and Gallagher: 97%) with bioimpedance method. The prevalence of hypohydration (12.9%) was tendentiously higher in women compared to men (W= 15.4% vs. M= 5.0%, p=0.087). Despite the frequency of osteoporosis was higher in women (W = 71.85% vs. M = 28.15%), 95% of men revealed criteria for osteoporosis. Resting metabolic rate (RMR) was significantly different between genders using bioimpedance analysis (W= 1123.33± 173.91; M= 1350.10± 188.88; p<0.001) or Harris Benedict equation (W= 934.92± 102.60; M= 1018.85± 171.68; p=0.001). Bland- Altman analysis between methods indicate that there was an agreement of 97.6%. The overall mean metabolic age obtained was 83.52±1.11 years, well below the chronologic age (p<0.001).

Conclusions

In Portuguese centenarians, clinical and nutritional approach should be improved on the gender basis. In relation to nutritional status, centenarians were more frequently underweight than overweight. The thinness could be a natural process, contributing for the longevity being rather overweight a reducing factor in life expectancy. BMI and waist circumference showed a good correlation with body fat percentage. Despite the results of Bland- Altman analysis, Deurenberg and Gallagher equations are not suitable to evaluate obesity prevalence in centenarians. Harris Benedict equation seems to be a good option to measure RMR in centenaries, when BIA is not available. Body composition and nutritional characterization of Portuguese centenarians are relevant contribution in scientific evidence production for the action plan of healthy ageing in Europe (2012–2020) and also for clinical practice.

The consumption of organic food has been increasing all over the world. Due to this fact, there are growing numbers of scientific studies examining the nutritional value of organic food. The aim of this review is to provide an overall picture of the beneficial and harmful nutritional content of organically and conventionally produced crops based on existing international comparative surveys. Furthermore, the authors attempt to define the relationship between organic and conventional food production systems and the nutritional value of food products as well as the consumption of organic and conventional diets which have important human health implications. Organic crops contain a significantly higher amount of certain antioxidants (vitamin C, polyphenols and flavonoids) and minerals, as well as have higher dry matter content than conventional ones. Moreover, there is a lower level of pesticide residues, nitrate and some heavy metal contaminations in organic crops compared to conventional ones. There is a relationship between the different fertilisation and plant protection methods of these two plant production systems and the nutritional composition of crops. Consequently, it can be concluded that organically produced plant derived food products have a higher nutritional value, including antioxidants than conventional ones. Furthermore, due to the fact that there is a lower level of contamination in organic crops, the risk of diseases caused by contaminated food is significantly reduced.  相似文献

The adequate nutritional support of severe protein energy malnutrition (PEM) in infants represents a great challenge. An accepted approach has not been established by most health professionals attending malnourished infants. The objective of this study was to determine if an improvement in the growth rate and body composition of infants with PEM occurred after receiving a starting infant formula with nucleotides. Twenty-five malnourished infants from 3 to 18 months of age participated in the study. All were fed through a nasogastric tube with infant formula (3.35 kJ/mL) for 2 weeks and ad libitum for another 2 weeks. Direct and indirect anthropometric indicators were determined. The subjects were divided into 2 groups; group 1 (n = 11) was fed a formula with added nucleotides, and group 2 (n = 9), with no nucleotides. A paired t test was used to determine the differences between the initial and final measurements for each group, and nonpaired t test was used to compare the groups. Indicators of growth and fat incorporation showed significant differences within each group (P < .001). The comparison of the rate of anthropometric changes showed no significant difference between the groups. Skin fold thickness and fat percentage were higher but not significant in group 2. An infant formula with an intake of 837 kJ/kg per day and protein of 4 g/kg per day in infants with PEM had a favorable impact on growth, fat incorporation, and body composition indicators regardless of the addition of nucleotides.  相似文献

The composition and nutritional adequacy of subject-selected high carbohydrate, low fat diets were investigated in six women with insulin-dependent diabetes mellitus. Subjects were randomly assigned to begin either the experimental diet with 65% carbohydrate, 20% fat, and 15% protein for 6 wk, or a control diet with 45% carbohydrate, 40% fat, and 15% protein for 4 wk. All subjects completed both dietary periods in a cross-over experimental design. Subjects were allowed free selection in their choice of carbohydrate-rich foods. The resulting selections produced diets with 51% simple and 49% complex carbohydrates and 50 g of dietary fiber during the experimental diet. Similar proportions were also selected during the control diet. Blood chemistries revealed no significant changes in thiamin, riboflavin, vitamin B6, pyridoxal 5'-phosphate, ascorbate, vitamin E, calcium, selenium, or zinc concentrations between the two dietary periods. With the exception of vitamin B6, all vitamin and mineral values were within normal respective ranges. Vitamin B6 status, as assessed by pyridoxal 5'-phosphate, were below or just above the levels of marginal deficiency (2.2 nmol/100 ml) in four of the six individuals, but the lower level observed occurred independent of the dietary treatments. The present study demonstrates that subject-selected high carbohydrate, low fat diets were much lower in complex carbohydrates and fiber than diets previously tested. In addition, the concentration of several nutrients did not appear to be adversely affected by these diets.  相似文献

Our results show the importance of a number of regional foods and suggest some differences in the dietary patterns of three ethnic groups in the same region. Dietitians and nutritionists should be aware of the rich ethnic diversity of dietary patterns and use this knowledge in nutrition counseling, program planning, and nutrition education.  相似文献

This paper suggests that proposed labelling schemes that categorize foods into bands should be tested prior to use to determine what proportion of foods consumed by the public fall into each category, and that the width of each band might best be based on either having similar numbers of foods in each band or to facilitate discrimination between 'healthy' and 'unhealthy' diets. As an example, a labelling scheme based on energy density has been tested using weighed diets of nutrition students; both those that were considered 'healthy' and those that failed to satisfy the suggestions of the National Advisory Committee on Nutrition Education.  相似文献
