The FDA has jurisdiction over tobacco[2] and various food products contributing to obesity and those are the only two examples highlighted by OP or me in the thread.

Don't think we are, there is very little money for Food part of FDA, in the last 5-6 years the money for food has gone from 1,037M(2018) to 1,145(2022)[1] which in real terms considering inflation means it has gone down and last 30 years it has been similar story.
Last Week Tonight had a recent in depth segment on how little resource we have for food enforcement[3] sometimes as little as singe digit inspectors for an entire industry.
We don't really enforce food regulations, because we don't fund the regulatory body for food safety.
