I am actually surprised that our schools and work places still have vending machines that sell all kinds of junk. Some of these foods are cleverly labeled "Healthy Choices". Here is one such a machine at a work place!
How about a machine that vends fresh fruits and raw nuts?
I am sure there is a market for it, just as there is a market for all the candy and chips.
How about more water fountains and less soda machines?
What will it take?
