Actually the OP is biking 15 to 30 km / dat to and from work, working a 12 hour day and drinking 3 liters of unsweetened fruit juice per day. Mango is the first choice. If I was at home I could cut the stuff up and run it through a blender and arive at about the same point.

I`m not sure where all the concerns about sugar are based on - your body breaks almost everything down to sugars to burn anyway and fructose is the easiest to deal with. By definition `sugar` is simply a crystaline form of carbohydrates.

And for anyone that still concerned - I weigh 155lbs, have a low body fat index and not even any remote signs of diabetes. In fact diabetes is more common in overweight people, middleaged people, individuals that exercise little, and for some reason - most common among blacks and hispanics.

But Montreal has a high humidity index and currently temperatures in the 30s and I need to drink a lot of fluids. The water in the area I work sucks.
