<<Debra,

Isnt that the one who authored a book on fish fat?  The tape - is it
about fish fat?

No I do not believe she authored a book on fish fat.  Some of her books are...
Beyond Pritikin
Super Nutrition for Women
Guess What Came To Dinner Parasites and Your Health

The audio "Those Big Fat Lies"  is basically an education on good/bad fats.
