, reported that Greger had called mad cow disease the "plague of the 21st century". However, Greger later denied ever making such a statement, clarifying that he had merely posed it as a question during a speech. That same year, Greger cited a study and said that "thousands of Americans may already be dying because of Mad Cow disease every year".
In 2004, he launched a website and published a book critical of the Atkins Diet

after the Humane Society released its undercover video of the Westland Meat Packing Company, which revealed downer animals entering the meat supply. This led the USDA to mandate the recall of 143 million pounds of beef, some of which had been routed into the nation's school lunch program. In 2011, Greger founded the website ''NutritionFacts.org'', with funding from the Jesse & Julie Rasch Foundation.
Reception
Greger's books have appeared on ''The New York Times'' Best Seller list multiple times, including ''How Not to Die'' three times, ''How Not to Diet'', and ''How Not to Age'' once each.
Greger's third book, ''Bird Flu: A Virus of Our Own Hatching'', received a favorable review which said it was "interesting and informative to both scientists and lay persons". Public health expert David Sencer was critical of the book, writing that it "focuses heavily on doomsday scenarios and offers little in terms of practical advice to the public" and that "a professional audience would quickly put he book

aside for more factually correct sources of information".
In 2024, Morgan Pfiffner of ''Red Pen Reviews'' gave his sixth book, ''How Not to Diet'' a score of 50% for its scientific accuracy and a score of 75% for its healthfulness. Pfiffner commented that "While much of the book is well supported by research, there are a significant number of fairly questionable claims, leading to a handful of dietary recommendations that seem unnecessary, too restrictive, or potentially counterproductive". He also argues that Greger's claim that a whole food plant-based diet can reverse heart disease is questionable. According to Pfiffner this has not been demonstrated as the randomized controlled trial that he cited from Dean Ornish did not show regression of atherosclerotic plaque.

argues that, while it is well-accepted that it is more healthy to eat a plant-based diet than a typical Western diet, Greger often overstates the known benefits of such a diet as well as the harm caused by eating animal products (for example, in a talk, he claimed that a single meal rich in animal products can "cripple" one's arteries), and he sometimes does not discuss evidence that contradicts his strong claims.

argues that although Greger takes his information from respected science journals and produces impressive videos, he has a vegan agenda and cherry picks his data. He adds, "Of course that doesn't mean the cherries he picks are rotten; they're fine."
