The Top 10 "Trans Fat" Foods:

Spreads.

Tip: Look for soft-tub margarine, because it is less likely to have trans fat. Some margarines already say that on the packaging.

Packaged foods

Tip: Add flour and baking powder to your grocery list; do-it-yourself baking is about your only option right now, says Moore. Or watch for reduced-fat mixes.

Soups

Tip: Get out the crock-pot and recipe book. Or try the fat-free and reduced-fat canned soups.

Fast Food

Tip: Order your meat broiled or baked. Skip the pie. Forget the biscuit. Skip the fries -- or share them with many friends.

Frozen Food

Tip: In frozen foods, baked is always heart-healthier than breaded. Even vegetable pizzas aren't flawless; they likely have trans fat in the dough. Pot pies are often loaded with too much saturated fat, even if they have no trans fat, so forget about it.

Baked Goods

Cookies and cakes

Donuts

Cream-filled cookies
