18 Supermarket Lies Revealed

5. The Conspicuous Trans Fats

Pop Secret Homestyle Popcorn

The Claim: "Made with a sprinkle of salt and a taste of butter"

The Truth: The taste of the butter is actually the taste of partially hydrogenated soybean oil, which imbues on this greasy bag a total of 18 grams of trans fats-more than seven times what you should safely consume in a day, according to the American Heart Association. No area of the supermarket is more riddles with these fats-proven to increase the risk of coronary heart disease-than the snack aisles, so be on high alert.

What You Really Want: Unadulterated popcorn. Buy a low-calorie bag like Smart Balance Smart Movie-Style, then flavor it at home with a bit of heart-healthy olive oil, grated Parmesan cheese, and fresh herbs.
