Fruit juice contrary to popular belief is not that healthy, and leads to weight gain, obesity etc. It is not the health benefit of eating the actual fruit. As for bottled water the issue here is social and environmental. Municipal water is in most cases just as healthy or even better (leached plastic) and be run through a filter if chlorine or fluoride is a concern. Bottled water is also a huge scam. Take a look at what these corporations pay for water http://www.env.gov.bc.ca/wsd/water_rights/water_rental_rates/cabinet/F-R_fees_Table-Feb4_Final.pdf. The wholesale rate is measured in millions of cube meters of water per year while the retail rate is measured in milliliters. Talk about a truly obscene mark up with huge negative environmental consequences.

Edit: Sports drinks are also very unhealthy. Way too much sugar for starters.
