Meh - it all tastes sweet.
Unless you're taking in a lot of fructose, a little bit won't hurt you. And there are times when you want it - depletion workouts come to mind.
Now, I checked on the "tons of vitamin C" thing:
"Orange juice is frequently bought as a frozen concentrate. Frozen, reconstituted orange juice has 78% and canned orange juice has 69% of the vitamin C found in fresh squeezed orange juice. Vitamin C is destroyed during the condensing process, but canning is even harder on vitamin C. It appears that fresh squeezed orange juice is better than either frozen concentrate or canned, but remember that the highest Recommended Dietary Allowances
for vitamin C is 60 milligrams and all three forms, fresh, frozen and canned provide more than the RDA of vitamin C in 2/3 cup of orange juice."
So there's a whopping what, one hundred mg of vitamin C in a full 8 ounces of juice, which contains more sugar than coca cola? I think I'll stick to my time-release pills for the 1000 mg I take daily. If I relied on OJ for this much vitamin C, I'd be knocking back 80 ounces a day - over 200g of sugar, half of which would be fructose! My poor wee liver probably can't hold that much! Besides, I'd really rather get those 800 calories from steak!
