Introduction: Adolescence is one of the most important periods of human development. Nutrition plays an important role in health and prevention of disease during this period. Food advertising influences food purchase and food consumption among children and adolescents. Most of these advertisements are about the foods high in fat, salt and sugar. High exposure to these kinds of a...

Rational junk-food consumption is analyzed within an expected lifetime utility maximizing framework in which longevity and productivity rise with health, and health deteriorates with junk-food consumption. As long as the junk food’s relative taste-price differential is positive, the consumer’s rational diet deviates from the physiologically optimal one and generates lower than maximal levels of...

Background and aims: Inappropriate or imbalanced consumption of foods may lead to several healthproblems, especially among adolescents, the complications of which will remain for several years.This study aimed to investigate perceptions, self-efficacy, and the status of junk food consumptionand their relationship with demographic variables in female high school students in Sha...

BACKGROUND Consumption of high calorie junk foods has increased recently, especially among young adults and higher intake may cause weight gain. There is a need to develop public health approaches to motivate people to reduce their intake of junk food. OBJECTIVE To assess the effect of health and social norm messages on high calorie snack food intake (a type of junk food) as a function of usu...

We have shown previously that a maternal junk food diet during pregnancy and lactation plays a role in predisposing offspring to obesity. Here we show that rat offspring born to mothers fed the same junk food diet rich in fat, sugar and salt develop exacerbated adiposity accompanied by raised circulating glucose, insulin, triglyceride and/or cholesterol by the end of adolescence (10 weeks postp...

The global increase in obesity rates has been tied to the rise in junk-food availability and consumption. Increasingly, children are exposed to a junk-food diet during gestation and early development. Excessive consumption of junk-food during this period may negatively impact the development of brain motivation and reward pathways. In this study we investigated the effects of a chronic junk-foo...

BACKGROUND The ubiquitous supply of junk foods in our food environment has been partly blamed for the increased rates in overweight and obesity. However, consumption of these foods has generally been examined individually perhaps obscuring the true extent of their combined consumption and impact on health. An overall measure of children's junk food consumption may prove useful in the developmen...
