Why should there be? When the definition of ultra processed seems to include almost any food that is a combination of other foods, it seems that any rules would be overly broad and restrictive or useless.<p>I’d like to see some research into what specifically in these foods is actually leading to worse health outcomes. Is it preservatives? Emulsifiers? Too much fat/sugar? Lack of fiber? Right now all I see is gesturing towards this class of food when the true reason for worse health outcomes seems much more related to the nutritional profile (i.e. how easy it is to overeat, or not get proper vitamins/fiber) to me.
