thousands of different food additives are allowed by the FDA, although a 2013 study found that almost 80% of them lack the relevant information needed to estimate the amount that consumers can safely eat. In the FDA’s own database, 93% of food additives lack reproductive or developmental toxicity data. Of the totality of FDA-regulated additives, both directly and indirectly allowed in food, almost two-thirds don’t have publicly available feeding data. The report concluded that in the absence of toxicology data on the majority of chemicals added to food, their safety in humans may be questioned.
