There is a lot of misinformation on the internet regarding 'BEG' pet food diets. BEG stands for Boutique, Exotic ingredients, or Grain Free.
In 2018, the FDA issued a warning to the public regarding a potential association between these foods and a form of heart disease. Studies are still ongoing and the scientific community is trying to figure out the exact mechanism(s). My point is, there appears to be sufficient concern for the FDA to issue a warning.
I have put together a list of hyperlinks to websites with discusses these diets, some of them pertaining to the diets and a link to heart disease. My goal is to provide to you reliable sources of information. We value educated pet owners There is a lot of misinformation and slick marketing out there regarding these foods which up to this point, has been harmless.
