Eating right is all about making healthy choices. You choose to have almonds instead of M&Ms, seltzer instead of 7-Up, yogurt instead of a Twinkie. Right? Wrong! At least, if you're keeping an eye on your sugar intake (and who isn't, especially after the recent news reports linking sugar not only to obesity but also to type II diabetes, hypertension, and heart disease?).

The Huffington Post's Healthy Living section has an eye-opening slideshow about foods that contain more sugar than a Twinkie. The one that really threw us for a fruit-loop wasn't kids' cereal but yogurt, that calcium-rich, go-to treat for for nutritionists, athletes and the nutrition-obsessed everywhere. HuffPo reports that an 8-ounce container of vanilla yogurt can have around 31 grams of sugar, while a 6-ounce container of the fruit-flavored kind can have around 32 grams. That's almost almost double the amount in a spongey, "cream"-filled snack cake!

But before you toss that tub, check the nutritional info, as sugar and portion sizes vary widely. For example, we found that that amount of sugar in Stonyfield Farms yogurt seems to increase in inverse proportion to the fat content: for French vanilla flavor, the non-fat had 17 grams, low-fat had 21 grams, and whole milk had 22 grams--more than a Twinkie, but less than the unspecified brands of yogurts HuffPo was referring to. Their slideshow did include this great piece of advice: When in doubt, or if nutrition info isn't readily available, go for Greek yogurt, which naturally has less sugar because of the straining process used to give it that thick, rich consistency. (Check out the slideshow to find out what other foods are more sugary than Twinkies--and let us know if any of these surprised you).
