Monsanto has come out with a new, more powerful version of aspartame called Neotame. This sweetener is so sweet that most likely it will consist of less than 1% of the ingredients in any given food product, which means it falls under the threshold where the FDA requires it to be listed on the list of ingredients. It may be lumped in with "Natural Flavors" on the label instead. Monsanto apparently only tested it on a small group of employees, some of whom reported headaches, which data was discounted and ignored.
At the same time, some scientist in the U.K. is calling for sugar to be classified as a toxin and regulated like alcohol.
The price of sugar is already up quite a bit, but don't expect it to come back down. In food preservation, you need sugar, salt, and vinegar or lemon juice. If you want to make your own hooch or your own soda pop, it's usually made from sugar water with flavors or juice in it.
I would recommend buying as much sugar as you can afford, now, before they regulate it to death. Or plant some sugar beets, and extract your own, although that's a lot of work.
