Who knows healthy water from a documented source?
The nutrition course I took today says that water only counts as good water unless it is from a "documented source" (tap water not counting) NAFC Nutrition Course. I looked at the bottle water I was drinking and it said it was "Deionized water from a local municipal source" Is this an example of "a documented water source"? Maybe there are good and bad documented sources as well. Can someone give me examples of good documented sources of water?
Also recommended was spending the most money you can on a home water filter...
Interesting subject, but I would like to see some of their research which they have done regarding this issue and where do they based their facts. It's true that water filters can improve some of the quality of the water, but they are not providing that much of an improvement. If you have any information it would be great.
If you are interested in information on the testing results of various municipal water supplies that information is generally available from the local water authority. It can be helpful to get that information before investing in an expensive filtration system for your home. Some water is fine, and if it is not you want the kind of system that removes the specific problem that is there.
And if you are traveling it can be helpful to find out what the water is like where you will be.
Of course bottled water comes with its own issues: plastic that does not break down, plastic that leaches into what you are drinking, bpa, ecosystem destruction, etc.... aside from the question of how good is what is being put into the bottle.
And before you buy a reusable water bottle it is good to compare the benefits of each type. (e.g. aluminum that is not coated could leach aluminum which has its own set of risks, plastic should be bpa free... etc)
And Harris is spot on. Whoever is presenting the class should be able to provide you with links or information on the original studies, or another source for their information.
