From the bottom of our artery clogged hearts, thank you. The Food and Drug Administration proposed regulations on Thursday to eliminate artificial trans fat from the U.S. food supply. The measures would deem hydrogenated oils (where trans fats come from) no longer safe. And since the Institute of Medicine says there is no safe level at which to consume artificial trans fats, companies will have a hard time challenged the proposal during the 60-day comment period. The FDA says the rules may prevent 20,000 heart attacks and 7,000 deaths a year.
