Actually, it's too late for that - at least for Trans Fats.

Interesterified fats in the new formula are still an open question that only long term (decades) studies will settle.

Proctor & Gamble invented Crisco as they were not doing well in the soap buisness with their hydrogenated cotton seed oil, and their candle business was in decline - so, sell the product as Health Food (no study required - it was white so it must be Pure). Pure was the buzz word of the time, like Natural is now.

Others have since followed this same solution for failing product lines, including Canola Oil, but in our times some study (and, it is suspected, some substantial pay-offs) was required.

Crisco was, of course, Trans Fats, made from partially hydrogenated cottonseed oil.

In a brilliant promotional move, Crisco became the major financial contributor to the new American Heart Association. They were followed by the seed oil companies that produce the artificial oils from which Trans Fats are made. This is why the AHA was still promoting Trans Fats when New York started a program to ban them (I personally checked the AHA Web site and saw this was true).

P&G dumped Crisco to J.M. Smucker Company, who reformulated it to use fully hydrogenated seed oils. Fully hydrogenated fats have another name which they don't mention due to the AHA's long vendetta against it, Saturated Fats.

Of course, this substance is hard as a hockey puck, so they blend it with liquid oils to make it soft like the original Crisco. It still has some Trans Fats, but the FDA allows them to call it "Zero Trans Fats" because it's less than 0.5 grams per serving.
