Why does the FDA allow harmful chemicals in foods?

The FDA allows certain chemicals in foods because they are deemed safe for consumption based on scientific studies and regulatory assessments. These chemicals can serve various purposes, such as preserving freshness, enhancing flavor, or improving appearance. However, the safety thresholds are established to minimize any potential risks, and the FDA continually reviews new evidence to ensure food safety standards are upheld. Critics argue that some harmful substances may still be permitted due to industry lobbying or outdated regulations, prompting ongoing debates about food safety policies.
