ABSTRACT

The chemical amaranth (AM) is permitted as a colouring agent in a variety of foods. Safety was established based on chronic rodent studies. AM and its metabolite naphthionic acid (NA) can be absorbed through the intestine, exposing circulating immune cells including splenocytes. An AM feeding study in rats demonstrated an increase in blood lymphocytes. Yet, in contrast, AM inhibited the delayed-type hypersensitivity reaction to antigen. DO11.10 mice express a T Cell Receptor specific for ovalbumin
