Is it chocolate?
This weekend, my brother and I did a bit of a survey at Food Bazaar to see which chocolate brands had vegetable fats (other than cocoa butter) in them. The results? All imported brands, such as Hershey's , Vochelle and Mars were made of cocoa butter and milk fats. And the two major brands sold in India, namely Cadbury's and Nestle, have Hydrogenated Vegetable Oils in them.
Now, you may ask, what's wrong with having vegetable fats in chocolate? Nothing, really, if you are not a chocolate purist. But there is definitely something wrong with having Hydrogenated vegetable oils in the chocolate. These fats have been shown to have many health risks, compared to saturated fats (such as from milk or even meats). There is a lot of awareness about these health risks in many countries in the west, and a lot of companies have started labeling their chocolate, saying "Does not contain any vegetable fat". Check out a bar of Mars.
ETA: After this post was posted, on reading one of the comments, I went to check the Cadbury brand again. And sure enough, there is no more mention of hydrogenated veg oils anymore! There are still some bars of choc that do have them, so if you are concerned, just flip it over and read the ingredient list before buying. :)
