Parke, over at U.S. Food Policy hits the nail on the head regarding the trans fat bans :
Even so, I must admit to fearing that this ban might overreach. Many products in the marketplace are bad for us. Only those products with the highest risks and no redeeming features should be banned. For those products that merely increase risks and have some merits, well-informed consumers can weigh the risk for themselves.
Trans fats may be a borderline case. In your own reflection, ask yourself why trans fats should be banned in restaurants but not barbecue pork ribs? Why ban trans fats in restaurants but not butter-drenched baked treats?
