TL;DR: The end product is the same, whether it be natural or artificial. The real concern, is if the product should really be consumed at all.

This is hot crap. They are different chemicals, the end product is not the same and you're spouting misinformation.

Most of the artificial dyes that people have banned in countries other than the USA are derived from petrochemicals. Natural dyes have been in use far longer and have been shown to have fewer negative health outcomes.

Eg. Red dye containing bugs (cochineal, E120) has no known health effects except to an extremely small percentage of the population whom are allergic to bugs, hence it is marked as an ingredient when used, to alert those with allergies. Its replacement alternatives are:

• red dye #2 (amaranth, E123) which was made from coal tar, and is now made from petroleum byproducts. It is a suspected carcinogen and is banned in most of the world including the US.
• red dye #3 (erythrosine, E127) was first extracted from coal tar and is derived from phenol, currently extracted from petroleum byproducts and it is a known carcinogen and restricted heavily in what it can be used in since the early 1990s in every developed nation except the USA, until this very announcement by the FDA and RFK jr which will bring the USA in line with the rest of the world's protections. California also separately banned it in October 2023.
• red dye 40 (Allura red) is an entirely synthetic dye invented by a chemical corporation in 1971 by azo coupling between diazotized 5-amino-4-methoxy-2-toluenesulfonic acid and 6-hydroxy-2-naphthalene sulfonic acid. I don't know what that means in order to determine if its feedstocks are petrochemicals, but mice studies showed bowel disorders and DNA damage which caused several countries to ban it over the years, however it's currently believed to be safe if the maximum daily limit is adhered to.

And that's just red dye.
