To the F.D.A., there is no difference between the trans fat that occurs in cows and the kind that is artificially created and favored in large-scale food manufacturing. And to Starbucks as well, who are now demanding all bakery products be "trans-fat free". So your Starbucks croissant? Made with palm oil, not butter. Butter, milk, and beef all have naturally occurring trans fats. Does this mean no more cheeseburgers in NYC because of our trans-fat ban?
Updated: In case you were worried about your NYC burger, the answer to that question is no. The NYC ruling would only ban artificial trans fats, not naturally occurring ones.
