Food purity and warnings against additives came from a lifelong crusade by a chemist named Wiley. But it was a battle against corporations and Congress. The corporations that were making money by putting formaldehyde into our food did not care about the effects. The parallel to this nowadays in the vaccine industry.
To clarify: Congress was not against him but rather simply refused to pass food purity laws. It was mainly the newspapers and corporations that were against him. So when we but soda we now what is in it and we are not worried about formaldehyde additives Why? Because of Wiley. But who remembers him nowadays?
Myself I admit that I would probably be more susceptible to the Covid-Vaccine-scam if not for the warning of Rav Nahman in the Conversations of Rav Nahman perek 50
