It's not often I get excited about a drink, but Fuze Tropical Punch tastes great with almost no calories. This Fuze flavor is primarily water, Pineapple Juice, natural flavors, and vegetable juice. It is sweetened with sucralose, also known as Spenda. I have no idea how they get all the sugar out of the fruit juice, but the final product tastes more like authentic fruit juice, rather than the odd approximations of so many carbonated fruit flavored drinks.
I accidentally found this drink at a small grocery in Bend Oregon. I was desperate for a drink to go with a banana to deal with leg cramps from too much snowboarding. I found this hidden in the refrigerator case, noticed the low carb designation and grabbed it. I was shocked at how good it tasted. Since then I look for it everywhere. Most places sell it for $1.50 a piece, which is pretty expensive to me. Still I think it's worth it.
Right now I'm finding Fuze in Portland Oregon at the Fred Meyers and Zupans. I've looked for it at the New Seasons, but no joy. I should note that Fred Meyers had some flavors on sale for around $1.30.
It's also interesting to note that it contains Chromium, Vitamin C, Super Citrimax, and L-Caratine. I have no idea if these additives have the advertised effects of suppressing appetite and boosting energy, but I haven't noticed any side effects that I can attribute to the drink.
