Abstract Background. Celiac disease has a high prevalence globally and to date the only effective treatment is a
strict gluten-free diet for life. Diet compliance is difficult due to current unhealthy eating habits and increasing
overweight/obesity, especially for school age children. Objectives. To assess availability, cost and nutritional
adequacy of gluten-free school snacks. Methods. Five store categories (large, regular-size and wholesale
supermarkets, health food stores and corner shops) were assessed in districts representing low, middle and high
socioeconomic levels. Three categories of school snacks were surveyed: dairy products (milk boxes, yogurts),
cereals (in bulk, cereal bars) and baked goods (various cookies). Portions and prices were standardized and the
closest gluten-containing products were matched for comparison. Availability, cost and nutritional quality (total
calories, total fat, carbohydrates and sodium) were then evaluated. Results. A total of 1562 products were assessed.
Gluten-free products were less available, with significant differences among the socioeconomic levels for cereals
and baked goods (P<0.05). Also, they were more expensive than gluten-containing products. Except for cereal
calories and sodium in the upper socioeconomic level, less than one third of the products available met FAO/WHO
recommendations. Products meeting all 4 characteristics (total calories, total fat, carbohydrates and sodium)
analyzed were 7.8%, 7.3% and 7.3% in the upper, middle and low socioeconomic level, respectively. Conclusions.
Gluten-free dairy products, cereals and baked snacks available as snacks for school-age celiac children are fewer,
with less variety and more expensive than gluten containing counterparts; the majority of them not meeting current
nutritional recommendations.

1. Introduction
Celiac disease (CD) is a condition observed only in
humans. It results from the interaction of genes and the
environment (gluten), with participation of the immune
system and host microbiota. A complex and only partially
understood damage to the small intestinal mucosa
develops, which includes an inflammatory disease and
autoimmune phenomena [1,2,3]. Today is known that its
frequency is close to 1% in most of the assessed countries
[4]. Increasing attention is currently given to the
difficulties that pose maintaining a gluten-free diet, the
only efficacious treatment of CD [5]. Compliance to a
gluten-free diet results in symptom remission, histological
and functional recovery of the small intestinal mucosa,
and decreased risk of complications [6]. Although a
gluten-free diet benefits celiac patients in many ways [7],
evidence shows that expenditures increase in those who
follow it [8,9]. Data also show that following strict gluten-
free diet deteriorates significantly quality of life, an area
that is poorly managed, mainly in less developed countries.
Gluten is widely used in food processing and gluten
contamination during the process of industrialized food
production is of frequent occurrence [10]. Because these
foods have poor elasticity due to the absence of gluten,
other specific components are added, often resulting in
increased content of fat and starch, i.e., higher in calories
in comparison with their gluten-containing counterparts
[11,12].
Given the changes of eating habits that modern life has
introduced in western societies favoring the consumption
of highly-processed foods, compliance to a strict gluten-
free diet is increasingly more difficult. Most studies in this
respect refer to US and European populations, but data
about the situation in other areas of the world is scant,
especially in those where bread and wheat based flour
consumption is high. Availability and cost of gluten-free
products is relevant because it may favor or hinder
compliance to treatment, and lower compliance is
