2. Packaged foods. Cake mixes, Bisquick, and other mixes all have several grams of trans fat per serving.
Tip: Add flour and baking powder to your grocery list; do-it-yourself baking is about your only option right now.

3. Soups. Ramen noodles and soup cups contain very high levels of trans fat.
Tip: Get out the crock-pot and recipe book. Or try the fat-free and reduced-fat canned soups.

4. Fast Food. Bad news here: Fries, chicken, and other foods are deep-fried in partially hydrogenated oil. Even if the chains use liquid oil, fries are sometimes partially fried in trans fat before they're shipped to the restaurant. Pancakes and grilled sandwiches also have some trans fat, from margarine slathered on the grill.  Tip: Order your meat broiled or baked. Skip the pie. Forget the biscuit. Skip the fries -- or share them with many friends.

5. Frozen Food. Those yummy frozen pies, pot pies, waffles, pizzas, even breaded fish sticks contain trans fat. Even if the label says it's low-fat, it still has trans fat.  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.

6. Baked Goods. Even worse news -- more trans fats are used in commercially baked products than any other foods. Doughnuts contain shortening in the dough and are cooked in trans fat. Cookies and cakes (with shortening-based frostings) from supermarket bakeries have plenty of trans fat. 
Tip: Get back to old-fashioned home cooking again.

7. Chips and Crackers. Shortening provides crispy texture. Even "reduced fat" brands can still have trans fat. Anything fried (like potato chips and corn chips) or buttery crackers have trans fat.  
Tip: Think pretzels, toast, pita bread.  

8. Breakfast food. Breakfast cereal and energy bars are quick-fix, highly processed products that contain trans fats, even those that claim to be "healthy."  
Tip: Whole-wheat toast, bagels, and many cereals don't have much fat. Cereals with nuts do contain fat, but it's healthy fat.

9. Cookies and Candy. Look at the labels; some have higher fat content than others. A chocolate bar with nuts -- or a cookie -- is likely to have more trans fat than gummy bears.  
Tip: Gummy bears or jelly beans win, hands down. If you must have chocolate, get dark chocolate -- since it's been shown to have redeeming heart-healthy virtues.

 
10. Toppings and Dips. Nondairy creamers and flavored coffees, whipped toppings, bean dips, gravy mixes, and salad dressings contain lots of trans fat.
Tip: Use skim milk or powdered nonfat dry milk in coffee. Keep an eye out for fat-free products of all types. As for salad dressings, choose fat-free there, too -- or opt for old-fashioned oil-and-vinegar dressing. Natural oils such as olive oil and canola oil don't contain trans fat.
