To clear up this topic: Triscuits that indicate 0g of trans fat and that do not indicate any ingredients are "partially hydrogenated" should be allowed in phase 2.
The South Beach books confirm that checking the ingredients list is the best way to check for trans fats.
The FDA's own statement on this is:
"Even if a food claims on its packaging to have "0 grams trans fat," it's a good idea to look at the ingredients list on the label, says Honigfort. Under current regulations, companies can make that claim if the food contains less than 0.5 grams of trans fat per serving. But if there is partially hydrogenated oil listed among the ingredients, the product will contain a small amount of trans fat. Selecting foods with even small amounts of trans fat can add up to a significant intake."
So, in the example mentioned earlier in this thread, if the ingredients list is:
Whereas, as previously mentioned, the flavored kind contain trans fats.
Compare the flavored kind of Fooducate:
...to the non-flavored kind:
Fooducate flags the flavored kind as "Contains trans-fats! Even if label says 0!"
