"It is now universally accepted that partially hydrogenated oils should be removed from our food supply as soon as possible. Partially hydrogenated oils contain trans fats that contribute significantly to premature heart attacks and other health problems.
About 40% of products in supermarkets contain them. Some health conscious markets such as Whole Foods will not sell any products containing partially hydrogenated oils. If the words "partially hydrogenated" or "shortening" are in the list of ingredients, don't buy that product, and if you've already bought it then just throw it away. You can always find an equivalent product which is just as tasty, without the partially hydrogenated oil."
