I would like more details on what "ties" means, since US Right To Know is a well known pseudoscience and fearmongering group, pushing anti-vaccine nonsense among other things. It doesn't help that "big agriculture, ultra-processed food companies, pharmaceutical companies and other corporate organizations" is ridiculously broad.
Yes, people on a food and nutrition panel are going to have some tie to...food and nutrition as a field. That's not a surprising statement.
And how they are connected to the specific companies listed needs explaining, since the US Right To Know group has in the past claimed that any form of email conversation or a company donating to a university someone works at counts as ties.
