What's wrong with sugar?

First of all, it is my belief that it not only causes behavioral problems, but I also believe that many children who are told they have learning disorders or hyperactivity are more likely eating poorly at home.
Kids like sugar. There is no denying that. And small amounts of sweets do not bother me. It is a problem to me, however, when EVERYTHING has added sugar, or worse high fructose corn syrup. Things that are already sweet, like canned fruit, does not need more sugar added on top of that!
Now I am going to say something controversial: Most juice is not good for you either. For one, they add sugar. For another, most juices have high fructose corn syrup. Juices that CLAIM to be healthy! Not only do they contain high fructose corn syrup but also added sugar, sodium etc. They are also boiled to a point where no nutrition could survive. They are concentrated and then water is added. By the time it gets to your glass it is flavored sugar water with chemicals added for taste.
How is that healthy? Oh because they added vitamin C.
A good example is V-8 Splash. Just check out that label some time. Good stuff. Just makes you want to jump in a lake of it.
Home made juice is better for you, but I still think of that as less than nutritious. Why? Because it is squished up and broken down. It isn't as healthy as a piece of fresh fruit.
Refined sugars are just bad for you, don't do them. They are as addictive as a drug. They feed the bad stuff in you like yeast, and they actually can make you more hungry if you eat them (especially high fructose corn syrup).
