Fruit juice immediately post training (with 50 gr whey protein, and with a scoop of Metamucil) being the sole exception IMO. Some might add creatine and a shot of Humulin-R; I don't suggest either for the casual athlete...
Wow, way to give out rubbish information. The fact you're even discussing administering a injection of synthetic insulin (Humulin-R) after exercise is a testament to that fact. I wouldn't recommend that to ANYBODY, "casual," amateur, or professional.
There is ZERO problem with fruit at any point of the day, even by itself. The "little bit of fiber" you mentioned, largely fermentable (soluble) does in fact help delay the absorption of fructose and slow digestion, promoting satiety. Fructose is generally more lipogenic when compared to glucose (although whether this actually translates to any physiological difference is a matter of debate), BUT this does not necessarily mean that fructose will automatically cause storage of fat - especially not in the concentrations we're talking about in a piece of fruit (what, 10-20g, at MOST?). Fructose CAN and IS converted into glucose equivalents or glucose itself, with the conversion modulated by whatever the needs are at the moment and the relative concentrations of enzyme substrates ('raw' materials). Let's also not forget the phytochemicals, vitamins, and minerals in fruit.
Fruit juice is calorific because it is concentrated fruit, and can be just as bad as soda in that respect - but not necessarily because of the fructose, but once again - because of the calories. The actual USDA guideline is somewhere around 8 oz/day maximum. That said, if you are looking to minimize recovery time post-workout, you would be best advised to consume a simple carbohydrate (e.g. white bread), which would accelerate glycogen resynthesis and muscular recovery.
