Dieticians keep telling us to eat more "healthy whole grains" and fish for optimal health.
One problem with this prescription is defining more. More than other foods? More than we're already eating? More than we ate last year?
There are, of course, formulas for what the dieticians think we should be eating. This percentage of one food, that percentage of another. But do you know anyone who sits down at the dinner table with a calculator to figure out what percentage of fat is in the meal?
