The Food and Drug Administration is re-evaluating its definition of what counts as a "healthy" food.
The change comes as healthful fats — including fats found in nuts — are increasingly recognized as part of a good diet.
Currently, if a food company wants to put a "healthy" claim on its label, regulations stipulate that it must be very low in fat. The specific rules are complex, but, for instance, a snack food can contain no more than 3 grams of fat for a regular-size serving.
This means that many snacks that include nuts don't qualify as healthy.
