It wasn't my intent. I have Google Alerts on "paleo diet." I read 
some, and occasionally post comments. This hospital dietitian:

Posted an article titled "Sioux City dietitian says popular fad diets 
are not sustainable"

I did write that she does not know much about the paleo diet. And I 
questioned where she got her information. She wrote that the paleo 
diet prohibits all root vegetables, including carrots. And that it 
allows seeds, and she couldn't understand why grains were disallowed 
if seeds weren't.

I posted two comments. I only have a copy of the first one. It ended:

The low-fat diet that dietitians have been promoting for the last 50 
years is the biggest food fraud ever in history. There are many books 
pointing this out. Nancy Rosston: Please read Nina Teicholz's "The 
Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy 
Diet" and come back and write an article for here explaining why you 
don't find the book's conclusion valid.
