The article doesn't address another factor which is whether corn-fed beef contains unhealthy plant lectins from its feed. Dr. Gundry "The Plant Paradox" book I read recommends avoiding lectins, which are protective proteins some plants produce to make animals sick so they won't eat the plant. Grain (high in lectins) fed meat is on the avoid list. I've been mostly following Dr. Gundry's book recommendations on avoiding high lectin plants plus products from animals that ate them (grass fed ground beef is more affordable at Aldi if one is near you plus better taste/smell than conventional). The biggest thing I noticed is my high cholesterol numbers went way down.
