I noticed this warning a week ago on the back of my jar of Hellman's mayo after I saw someone post an image of the warning on the fediverse. I threw it away and went to the grocery store to check out the other brands. Surprisingly Hellman's was the only brand that had that warning. I bought the expensive glass jar that specifically said no GMO.
Out of curiosity I browsed around looking at everything that I thought would have corn or soy. To my surprise all Campbell's soups have the warning, except for the Well Yes! line of soups, which advertises non GMO.
I think it's safe to assume that even if the warning isn't there, if the product is not organic or specifically states non GMO, then it probably is using GMO if it contains corn, soy, or sugar in any form.
So what's the deal with GMO anyways? Are we all going to have accelerated cancer growth? Drop men's testosterone levels even further? Turn everyone into a tranny? Probably.
