I read the whole interview and I'm very skeptical. How can a mummy be 
aged so precisely, after 1600 years, that her age can be stated, without 
reservation, as 53?
The data on kids who were fed ketogenic diets for years to treat 
seizures have been followed up after a decade or more and they have not 
shown any signs of such problems. The Masai, Inuit, and even the 
Trobriand islanders provide data that doesn't square with Dr. Cordain's 
claims and I can't access those sources even though I'm confident that 
he has relayed the content accurately.
People eating a SAD diet have plaques reduced after shifting to a 
ketogenic diet. Laboratory data reflect similar dynamics.
Sorry, I don't know what is going on here, but I don't think these data 
are accurate. They don't jibe with information that comes from much more 
reliable sources.
That's one man's opinion.
