you should watch the video because what she actually says is that she supports changing the national dietary guidelines to recommend healthier eating habits (and nothing further). the federal government has published these dietary guidelines every five years since 1980, and no honest person would call them "regulation".
harris also says in the video she likes eating burgers and doesn't want to ban meat, so the pork chop gotcha makes no sense. the link is 100% fake news.

^this is the document which your story terms "regulation". it could not by any conceivable standard be considered law. it is clearly intended as a public service to help americans avoid obesity, diabetes, & heart disease, which are severe illnesses widespread in this country. is updating these guidelines a critical government function? no. i highly doubt it is effective. but it would hardly be a socialist revolutionary undertaking for the biden admin.
