Within the last three or four decades proprietary articles, either real or so-called foods, have been offered to the public in greatly increasing numbers. These have very properly received special consideration for two reasons, (1) in many instances remarkable but utterly unfounded claims have been made for their nutritive value, thereby deceiving an undiscriminating public, and (2) the general high cost of a unit of nutritive value in them as compared with home preparations of equal or greater nutritive efficiency. No more striking examples of deceptive or even utterly false statements and of bad business ethics are to be found than are shown in the exploitation of some of these articles.
