Unfortunately, this is a foundation where the meat industry has certainly influenced.
They list FISH / Milk and extra OILS among their top recommended foods for arthritis..
And in their few vegan articles, they downplay the effectiveness of a vegan diet.. and continue to arbitrarily recommend eggs and oil consumption in the same article.
This is a known meat industry obfuscation tactic..
Oil in excess of 10% of total calories causes damage to the endothelial layer of ones' blood vessels..
Even if you take a LESS saturated oil, it still has 5 to 15% saturated fat.. Which would clog arteries all the same as fats from meat consumption.
If you eat animal PROTEIN, be it fish or eggs, then that causes the body to enter an inflammatory state for up to 5 hours per meal..
So, if a person eats approximately every 5 hours, he is spending the entire day under bodily duress..
All this ontop of the fact that animal protein consumption greatly increasing the rate of cancer cell growth..
