The trans fat ban has been in effect in many major restaurant chains (and health conscious households) for quite some time now. People are becoming increasingly aware of the risks this unhealthy fat poses to cardiovascular health and expanding waistlines. As such, trans fat is slowly being phased out of the American diet, but slowly is certainly the operative word.

According to a recent article in Men's Health, there still are plenty of cities or states where trans fat bans failed to pass. Furthermore, there are quite a few fast food chains that continue to offer foods that are high in this artery-clogging fat.

What foods most commonly contain trans fat? Here's what Men's Health had to say:

• Donuts
• Biscuits
• Pies
• French Fries
• Cookies (especially ones with fillings)

And what fast-food chains are serving up the most trans fat?

• Krispy Kreme
• Burger King
• Pizza Hut
• McDonald's
• Chick-fil-A
