The word "healthy" has had some interesting interpretations over the years. In the 1990s, anything fat-free was able to carry the "health" label even if it was loaded with sugar.
But, thanks to dozens of studies and reports, Americans are more aware of what "fat" actually means in relation to our diet.
"Nuts have healthy fats... that we know are good for cardiovascular health and mental health and are good sources of protein," says Thomas Sherman an associate professor at Georgetown University.
Thanks to all the hard work of nutritionists and dieticians the Food and Drug Administration is finally taking notice and re-evaluating the definition of what counts as a "healthy" food.
As the FDA rules stand now, if a food company want to put a "healthy" claim on its label, regulations stipulate that the food must be low in fat.
The push for a change came when the maker of Kind bars pushed back aginst an FDA complaint its use of the phraes "healthy and tasty" was false.
While specifics vary, a snack food like Kind would have to have 3 grams of fat or less to be able to use the word "healthy" on its label. Since Kind contains nuts, the fats are usually around 10 grams or more.
