The aim of this study was to objectively examine the knowledge that adolescent’s aged 12 to 17 from the island of Gran Canaria posses about content and composition of foods. At the present, it has been described an increasing prevalence of overweight and obesity in children of all developed countries, representing a potential threat to health. From a preventive point of view, it’s important to research the connection between the risk factors associated with lifestyle and biological factors that could be involved in the development of obesity, as well as the type of physical activity or sport which they practice and with the degree of knowledge on nutrient content and composition of food that these students have, in order to detect negative habits.
For this study we analyzed a sample of 1,364 schoolchildren, elected by simple random sampling, between schools on the island of Gran Canaria.
