I wonder how this study can be reconciled with the carnivorous diet, which is apparently high in good fats and good cholesterol. There is also the notion of structured water and a deficient exclusion zone which could explain the presence of plaque in the vessels according to Thomas Cowan, for example. So, I'm not sure that the factors that prevent plaque formation are those indicated. Nutrition is a complex matter.

It cannot. Well mostly. As I said, heart disease when eating high meat diets will only be risky for those people with the wrong genetics, mostly if you have disorders of B6 metabolism, carnivore will be bad for you.
The plaques are also formed by lipid oxidation so oxidative stress plays a role as well.
