nutritionfacts.org is vegan propaganda and shouldn't be confused with a good source.
Nutritional science is hard and we have very limited ability to actually study it and make strong recommendations. Cherry-picking phrases and results from limited power studies just muddies the waters.

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.
