"Dietary fat during childhood may be more life-threatening
than was originally suspected...Overweight children are
usually the victims of the dietary habits of the adult
members of the family...Reducing dietary fat to levels
necessary to the control of cholesterol cannot be achieved
if a child drinks whole milk or eats cheese."

Charles Attwood, M.D.

"The fats of plant origin in the cow's diet contain
large amounts of polyunsaturated fatty acids. These
fats are hydrolyzed in the cow's rumen. The liberated
fatty acids are then converted into saturated fatty acids."
