Trans fats are often portrayed as the big bad wolf, out to get your heart. As a result, restaurants proclaim that those fats aren't used in their kitchens, and grocery stores are fully stocked with trans-fat-free items. It's true that trans fats are no friend to your heart, but blindly buying up items with trans-fat-free labels isn't the way to keep your heart protected. For one thing, products that claim to be trans-fat-free can still contain up to half a gram of trans fats and maintain the label. If the serving size is small, and you consume the whole package, then you could easily gobble up a good deal of trans fats. And a product low in trans fats could still be chock-full of saturated fats, which are No. 2 on the heart's enemy list. To make sure you're feeding your heart with the good stuff, read the entire food label, considering serving size, total fat, cholesterol, sodium and sugar, just to name a few.
