Socio-environmental and parasitological aspects of waste pickers in Minas Gerais, Brazil

The increase in the generation of Solid Urban Waste causes social, environmental problems and damages to the population's health. Professionals who work in the collection of recyclable waste are exposed to risks of contamination either by toxic elements or pathogenic organisms. The objective of the work was to estimate the types and prevalence of intestinal parasites inwaste pickers. A field research was carried out from December 2017 to April 2018 with the voluntary participation of 26 waste pickers belonging to three associations in the municipality of Conselheiro Lafaiete, Minas Gerais, Brazil (CAAE: nº 79937817.7.0000.8122). In addition to the application a socio-environmental questionnaire, each volunteer provided a stool sample for laboratory testing the parasitological examination. Of the 26 survey participants, four (15.4%) had a positive result and were infected by the parasites Giardia lamblia, Entamoebacoliand Iodamoeba butschlii. Among the main factors that can contribute to the infection these waste pickersare the ingestion of untreated water for consumption in addition to reduced access to Personal Protective Equipment(PPE) during waste management. One way to control the presence of parasites would be through health and environmental education actions, periodic parasitological examinations and permanent use of PPE.

Nutritional composition of fad diets published on websites and blogs / Composição nutricional de dietas da moda publicadas em sites e blogs

ABSTRACT Objective To analyze quantitatively the diets available on blogs and websites. Methods The following 15 diets were analyzed: low-carb diet, gluten-free diet and intermittent fasting diet using the Virtual Nutri software program. The nutrients analyzed were as follows: carbohydrates, fibers, proteins, lipids, iodine, sodium, calcium, magnesium, iron, zinc, manganese, phosphorus, selenium, vitamins A, C, B6, B12, D, niacin, and folate. The nutrient values were compared with the Dietary Reference Intake recommendation for adults between the ages of 19-50 years. The macronutrient adequacy percentage was based on a 2000-kcal diet for a healthy life, as recommended by the World Health Organization. Results It was observed that most of the composition of macro and micronutrients was lower than the one established by the World Health Organization and the Dietary Reference Intake recommendation for adults between the ages of 19-50 years. Conclusion Long-term dieting can be a risk factor for several deficiency diseases and may endanger the health of individuals.

RESUMO Objetivo Analisar quantitativamente dietas disponíveis em blogs e sites.

Os nutrientes tiveram seus valores comparados com recomendações diárias de ingestão das Dietary Reference Intake para adultos da faixa etária de 19 a 50 anos. O percentual de adequação foi feito baseado em uma dieta de 2000kcal para indivíduos saudáveis, de acordo com o preconizado pela Organização Mundial da Saúde.
