Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it. I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*

My husband refuses to eat fish, but he LOVES this. It only takes 10-12 minutes to make, and is way better than any other kind of Tuna Helper I've tried. Besides the box itself, you'll need: - 1 can of tuna (6 oz., or I use 8 oz.) - 1 tablespoon of butter - 1 cup of milk It's a breeze to prepare, just DON'T leave it alone before you put the tuna and pasta in. Because of the milk, it likes to boil over. Just keep an eye on it and reduce the heat right after it starts boiling.

Looks can be deceiving, especially with this product: The cute, tiny can looks great, but don't fall for it! This little guy packs an amazing 140 calories per 8.3 oz can. My favorite 24 oz Arizona Iced Tea(black/white tea with sugar) has almost just as many calories(150) and almost 3 times the size of Switch. Also, do not be tempted with "100% Vitamin C and 20% Vitamin E" pitch either. Most of us consume 100% of daily Vitamin C without even trying through foods and anything extra get eliminated. The taste however does feel a bit more natural than other artificial orange sodas though, so that's the only plus. Also, if you do not worry about gaining weight, I guess this is a good way to get a sugar rush in a tiny can. Overall, a good-tasting product, but there are many other low-caloric alternatives out there. A can of Diet Coke and a multivitamin anyone?
