Trans fat

Great New Tork Times article on Trans fat which explains something I saw this week. At work we have supplies of various snacks and I was looking at the Pringles to see what was in them. The seal proclaimed 0g trans fat in huge letters. I read the ingredients and found that one of the flavours (sour cream and herb?) had some partially hydrogenated oils, in other words it did contain trans fat. I was gobsmacked. But the Food and drug administration allows a product with less than half a gram per serving to claim the product has no trans fat. So even when new labelling laws force companies to list trans fat explicitly we will still have to keep reading ingredients lists if we want to avoid it.
