This study establishes data on polyphenols, tocopherols, and antioxidant capacity (AC) of virgin argan oil. A total of 22 samples from Morocco were analyzed. Total polyphenol content ranged between 6.07 and 152.04 mg GAE/kg. Total tocopherols varied between 427.0 and 654.0 mg/kg, being g-tocopherol the major fraction (84.68%); a-, b-, and d-tocopherols represent 7.75, 0.33, and 7.29%, respectively. No influence of oil extraction method on total tocopherols was observed. The AC of argan virgin oils determined by the ABTS method in n-hexane oils dilution ranged between 14.16 and 28.02 mmol Trolox/kg, and by the ABTS, DPPH, and FRAP methods in methanolic oil extracts between 2.31-14.15, 0.19-0.87, and 0.62-2.32 mmol Trolox/kg, respectively. A high correlation was found between ABTS and DPPH methods applied to a methanolic oil extract. Virgin argan oil presents a higher polyphenol and tocopherol content, and total AC than other edible vegetable oils.

Metal content was determined in 26 samples of virgin argan oil from Morocco. An ETA-AAS with previous sample dilution with MIBK technique was used. In oil obtained by traditional method, Fe ranged from 0.8 to 4.0 mg/kg, Cu from 160.4 to 695.7 microg/kg, Cr from 10.3 to 55.3 microg/kg, Mn from 18.1 to 70.8 microg/kg, and Pb from 28.5 to 450.0 microg/kg. In oil obtained by a half-industrialized method, Fe ranged from 0.8 to 1.7 mg/kg, Cu from 158.4 to 385.0 microg/kg, Cr from 10.0 to 48.1 microg/kg, Mn from 15.0 to 68.5 microg/kg, and Pb from 32.0 to 100.0 microg/kg. Acidity value, peroxide index, K270 and K232, humidity and sludge volatile, and insoluble sludges in petroleum ether were also determined. A high variability in these quality parameters and a decrease of the quality in the oils obtained by the traditional method were observed.

Muros et al Health Promotion in a Spanish Pediatric PopulationPage 1 of 10 Background: The aim of this study was to determine the effects of nutritional education and vigorous physical activity on healthrelated parameters. Methods: The sample group consisted of 134 children from 5 rurally located schools. Participants were divided between 5 different experimental groups: control group (CG), physical activity group (PA), nutritional education group (NE), combined intervention group (PA+NE), and a combined intervention group with additional substitution of normally used oil for extra virgin olive oil (EVOO; PA+NE+EVOO). The intervention consisted of 60 minute sessions of physical activity held twice a week as well as nutritional education sessions held over 6 months. Results: Students in the groups receiving physical activity reduced their fat percentage and increased their muscle mass post intervention. At posttest the lipid profile improved in all intervention groups. The proportion of macronutrients and dietary cholesterol improved in the groups receiving nutritional education. The posttest comparison showed significantly lower fat percentage, sum of skinfolds and waist circumference in NE relative to CG and PA relative to CG. Diastolic blood pressure and glycaemia were significantly lower in PA+NE+EVOO relative to CG. Conclusion: A school-based program consisting of nutritional education or nutritional education plus a physical activity program showed a positive effect on healthrelated parameters in children. Keywords: sport, healthPhysical inactivity is considered to be one of the main threats to public health in the 21st century.1 Physical activity is negatively associated with overweight and obesity, and positively associated with cardiovascular health in young people.2 Increases in aerobic capacity are inversely related with improvements to specific health parameters in youth, including the lipid profile, 3 insulin resistance, 4 fat mass 5 and parameters associated with metabolic symdrome. 6Nutrition has been labeled as one of the main modifiable determinants of chronic diseases.7 Establishing healthy eating habits during childhood and adolescence is important, since it has been shown that food preferences and eating habits are established in early childhood and can persist into adulthood. 8 Research suggests that many children consume sugar, salt and saturated fats in excess of recommended amounts and at the same time fail to consume the recommended amounts of fresh fruit and vegetables. Lifestyle changes away from the traditional Mediterranean state in the Western world 14 Following on from studies, which have demonstrated improvements in some physiological risk factors 15 using vigorous physical training programs with obese children and adolescents during after-school hours, the American Heart Association has recognized the importance of prevention and treatment. In addition, it is important to involve parents in healthy interventions, as parents have a strong influence on the eating habits of young peo...
