Misleading label on food packaging

I just saw the advertisement of one famous fresh milk brand. On the pack, it is stated that "Trans fat Free". Maybe consumer would think that this brand is healthier and buy their product? Do you know that very little trans fat exist in natural product?

Transfat is produced by hydrogenating the oil to make it more stable. In this way, the food could last longer, e.g. baked products. Only in these few years, more people pay attention to the danger of consuming product with trans fat. I think the manufacturer is trying to gain point by stating their product is free of cholesterol, trans fat etc, despite the fact that these substance might not exist naturally at all. Same situation happen for peanut butter with "no cholesterol" label. It doesn't exist in the first place.
