Ziploc is marketing a new snack bag sized for a pack-and-go 100 calories, and food corporations have been touting 100-calorie-shot salty and sweet carbs in feather-light bags for awhile now. Worth it? FitSugar recently asked readers if the 100-calorie Ziploc bags were cool or not cool, and the vote is about split.

One commenter pointed out 100-calorie snack portions are not all the same -- consumers stuffing this bag full with mixed nuts or dried fruit will swallow way more than 100 calories. And plastic bags won't save the planet. How about some self-control and a piece of fresh fruit or tupperware full of fresh veggies instead?

What's your favorite 100-calorie or so snack to keep you thin? Ziploc says about 28 grapes, 2 tablespoons of mixed nuts and one small orange are good choices, but how about this -- a fresh apple served with an iPod and treadmill.

Here are a few more 100-calorie snacks over at AOL Health.
