The nutritional value of
gluten-free products is the subject of interest for food technologists and nutritionists, as the only effective treatment for
celiac disease is a lifelong
gluten-free diet. As
selenium deficiencies in
celiac disease are observed, the aim of the study was to determine the
selenium content in 27 grain
gluten-free products available on the European Union (EU) market. Moreover,
selenium content in products based on popular
gluten-free cereals like corn, rice, and buckwheat and in relatively new or less popular products based on oat, amaranth, teff, and quinoa was compared.
Selenium content in the tested products ranged from 0.9 to 24.5 μg/100 g. The average content of
selenium in products based on popular
gluten-free cereals was 2.8 μg/100 g and in products based on oat, amaranth, teff, and quinoa was 10.8 μg/100 g. It indicates that products based on less popular grains, especially on oat, should be more frequently chosen as a source of
selenium by people on
gluten-free diet than traditionally consumed
gluten-free grains.
