For example, boric acid was widely used as a food preservative from the 1870s to the 1920s, but was banned after World War I due to its toxicity, as demonstrated in animal and human studies.

In the United States, this led to the adoption of the Delaney clause, an amendment to the Federal Food, Drug, and Cosmetic Act of 1938, stating that no carcinogenic substances may be used as food additives.
During World War II, the urgent need for cheap, available food preservatives led to it being used again, but it was finally banned in the 1950s.
However, after the banning of cyclamates in the United States and Britain in 1969, saccharin, the only remaining legal artificial sweetener at the time, was found to cause cancer in rats.
Since 1987, Australia has had an approved system of labelling for additives in packaged foods.
However, in 2000, saccharin was found to be carcinogenic in rats due only to their unique urine chemistry. ===Hyperactivity=== Periodically, concerns have been expressed about a linkage between additives and hyperactivity, however "no clear evidence of ADHD was provided". In 2007, Food Standards Australia New Zealand published an official shoppers' guidance with which the concerns of food additives and their labeling are mediated.

Due to the application of the Delaney clause, it may not be added to foods, even though it occurs naturally in sassafras and sweet basil. ===Toxicity=== In 2012, the EFSA proposed the tier approach to evaluate the potential toxicity of food additives.
In July 2018 the American Academy of Pediatrics called for more careful study of those three substances, along with nitrates and food coloring, as they might harm children during development. ==Safety and regulation== With the increasing use of processed foods since the 19th century, food additives are more widely used.
