Fish is a good example of a ‘‘nutraceutical’’ food
because it is an important source of nutraceutical products
such as fish oil. It also contains a readily-digested protein
and hence is ideal for people with delicate stomachs. Nevertheless,
such a good food would be more complete if its
fiber content was increased. Many children and adolescents
in western Europe consume products containing essentially
proteins or fats but consume hardly any foods providing
the necessary intake of fiber.
