The iconic orange juice brand Tropicana is feeling the squeeze of financial pressures affecting both its supply and demand.

A 6-ounce serving of orange juice has 84 calories ... then has a "mocktail" -- a nonalcoholic, preferably zero-calorie beverage (like sparkling water with a lime) that looks like the real thing.

But as delicious and satisfying as these beverages can be, smoothies, iced coffee beverages, and other frozen sippers can also be full of calories ... a banana, orange juice, and vanilla yogurt.
