I just today went to an engaging tour and lecture in an historical farm house, about life in the 1700s. Much of the lecture took place in the kitchen. And I learned something I didn t know about butter. If a cow eats hay, the butter is white. If a cow eats grass the butter is yellow- because grass -believe it or not -has a lot of fat.

Grass ! Grass, like the grass on your lawn, is fatty! Does this give me reason to ignore my nutritionist 's advice to eat more salads?
