evidence: As is so often the case with "proprietary" industrial products like toxic perfumes (read more in my blog on microscopic toxins in perfumes), natural flavors (read more in my blog, Hidden Sources of MSG), and other food additives, the actual ingredients in Apeel are far from clear unless you do your own research. [...] The assurance Apeel gives us is typical corporate jargon: "Apeel products do not contain hazardous ingredients that will cause harm to people or the environment within the context of their intended use." [...] According to an Environmental Protection Agency (EPA) document, Apeel’s product is also .66% citric acid. Link here. So for anyone avoiding this widely-used but toxic food additive, Apeel is a no-go.
