Energy contribution of NOVA food groups and the nutritional profile of the Brazilian rural workers' diets.

ABSTRACT: We estimated the caloric contribution of minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods in Brazilian farmers' diets and their association with the nutritional profile of the diet. It is an epidemiological study of cross-sectional, analytical and quantitative design with 740 farmers adults of Southeastern Brazil. Food intake data were obtained by applying three 24-hour recalls and were classified according to the degree and purpose of processing. The largest caloric contribution came from the group of minimally processed foods (64.7%), followed by ultra-processed foods (17.7%), processed culinary ingredients (12.4%), and processed foods (5.2%). Individuals in the fourth quartile of caloric contribution from minimally processed foods showed lower energy consumption (? -0.16, P<0.001) and greater consumption of all 15 micronutrients analyzed. In contrast to what was identified for this food group, the higher caloric contribution from ultra-processed foods was associated with a greater caloric content of the diet (? 0.17, P<0.001) and lower consumption of all 23 analyzed nutrients. Therefore, the caloric contribution from the consumption of ultra-processed foods in the rural area is still lower than the national average. However, measures aimed at delaying isocaloric exchanges for the group of ultra-processed foods must be carried out, maintaining the local food culture, since this group had worse nutritional levels. In addition, incentives to the greater consumption of minimally processed foods should be carried out, due to their nutritional quality.

Project description:The cardiovascular and other health benefits and potential harms of protein and micronutrient deficiency of vegetarian diets continue to be debated.Study participants included urban migrants, their rural siblings and urban residents (n = 6555, mean age - 40.9 yrs) of the Indian Migration Study from Lucknow, Nagpur, Hyderabad and Bangalore. Information on diet (validated interviewer-administered semi-quantitative food frequency questionnaire), tobacco, alcohol, physical activity, medical histories, as well as blood pressure, fasting blood and anthropometric measurements were collected. Nutrient databases were used to calculate nutrient content of regional recipes. Vegetarians ate no eggs, fish, poultry and meat. Using multivariate linear regression with robust standard error model, we compared the macro- and micro-nutrient profile of vegetarian and non-vegetarian diets.Vegetarians, (32.8% of the population), consumed greater amounts of legumes, vegetables, roots and tubers, dairy and sugar, while non-vegetarians had a greater intake of cereals, fruits, spices, salt (p?<?0.01), fats and oils. Vegetarians had a higher socioeconomic status, and were less likely to smoke, drink alcohol (p?<?0.0001) and engage in less physical activity (p?=?0.04). On multivariate analysis, vegetarians consumed more carbohydrates (??=?7.0 g/day (95% CI: 9.9 to 4.0), p?<?0.0001), vitamin C (??=?8.7 mg/day (95% CI: 4.3 to13.0), p?<?0.0001) and folate (??=?8.0 mcg/day (95% CI: 3.3 to 12.7), p?=?0.001) and lower levels of fat (??=?-1.6 g/day (95% CI: -0.62 to -2.7), p?=?0.002), protein (??=?-6.4 g/day (95% CI: -5.8 to -7.0), p?<?0.0001), vitamin B12 (??=?-1.4 mcg/day (95% CI: -1.2 to -1.5), p?<?0.0001) and zinc (??=?-0.6 mg/day (95% CI: -0.4 to -0.7), p?<?0.0001).Overall, Indian vegetarian diets were found to be adequate to sustain nutritional demands according to recommended dietary allowances with less fat. Lower vitamin B12 bio-availability remains a concern and requires exploration of acceptable dietary sources for vegetarians.

Project description:This study aimed to investigate food truck consumers' profile, choices, preferences, and food safety importance perception. We conducted structured interviews with a convenient sample of 133 food truck consumers in the Federal District, Brazil. Most of the participating consumers were married (52%) and female (56%), who had completed at least tertiary school (81%). The interviews revealed that most food truck consumers eat from food trucks once or twice a week (96%), usually near home (74%), and have an average per capita expenditure of approximately US $5 to US $9.99 (70%). Hamburgers and sandwiches are the most popular food among consumers (72%). Consumers indicated that taste (30%) was the most important reason to choose a food truck and that poor vehicle hygiene (30%) was the main point assigned for not opting for a food truck. Food hygiene and vendors' personal hygiene were considered important by consumers when eating from food trucks (78% and 80%, respectively). Considering all food truck consumers interviewed and the questions about food safety importance perception, the minimum score was 1 and the maximum was 2.9, with a mean score of 1.68 (SD = 0.46), indicating a high level of perceived importance. The instrument of food safety importance perception presented a Cronbach's alpha coefficient of 0.73, indicating good internal consistency. No significant differences were observed in the food safety importance perception scores in gender (0.192), marital status (0.418), level of education (0.652) or food safety training (0.166). However, significant differences were found in the food safety importance perception scores for age (0.026) and the presence of children (0.001). The findings of this study indicate that there remains the need for consumers to comprehend their role in the food supply chain. Food safety and food handling practices are of public concern, and strategies are required to prevent foodborne diseases. Future public health interventions aiming to increase consumer knowledge and awareness of food safety should be emphasized.

Project description:BackgroundUltra-processed foods are recognized as indicators of an unhealthy diet in epidemiological studies. In addition to ultra-processed foods, the NOVA food classification system identifies three other groups with less processing. Unprocessed foods that, together with minimally processed foods (MPF), make NOVA group 1, NOVA group 2 is processed culinary ingredients, and NOVA group 3 is processed foods.ObjectiveTo assess the relative validity of the semi-quantitative food frequency questionnaire (SFFQ) to estimate the energy intake for each group NOVA classification system by comparing it with two 24 h-dietary-recall (24DRs) Mexican adults.MethodsWe analyzed dietary information from 226 adults included <60 and ≥60 years with complete SFFQ and two 24DRs from the National Health and Nutrition Survey 2012. We reported mean differences, Spearman correlation coefficients, intra-class correlations coefficients, Bland-Altman plots, and weighted kappa between measures.ResultsThe percentage energy intake from unprocessed and minimally processed foods group, Spearman correlation coefficients was 0.54 in adults <60 years and 0.42 in adults ≥60 years, while ultra-processed foods group was 0.67 and 0.48, respectively. The intra-class correlation coefficients in the unprocessed and minimally processed foods group was 0.51 in adults <60 years and 0.46 in adults ≥60 years, and for the ultra-processed foods group were 0.71 and 0.50, respectively. Bland-Altman plots indicated reasonably consistent agreement for unprocessed and minimally processed foods group and ultra-processed foods group in adults <60 years and adults in the ≥60 age group. Weighted kappa was 0.45 in the ultra-processed foods group to adults <60 years and was 0.36-≥60 years.ConclusionThe SFFQ had acceptable validity to rank the percentage of energy intake from unprocessed and minimally processed foods group and ultra-processed foods group in Mexican adults, both in adults under 60 years and who were 60 years old or older.
