Sugar. How can something that tastes so good be so bad?
People throughout history have loved the taste of sugar. Wars have been fought over it and some people love it more than they love their spouses. However, it causes some serious dental problems.
When the bacteria (germs) in your mouth are given sugar they use it as a food source. Their waste product is acid and this acid can eat holes in your teeth in which the bacteria can now live. This is called a cavity and has to be taken out and replaced with a filling by your dentist. If people never had sugar they would never get a cavity.
In America sugar can be found in many things, it is very hard to cut it out completely. Most dentist are realist and realize that many cannot cut it out completely. I myself would not find life worth living if I could never have a piece of cherry pie again. But you can cut down the amount of sugar you and your children get drastically. For example, substitute water for sports drinks and sodas. Put cinnamon in your coffee instead of sugar- you get the idea.
I think it would be hard to argue that reducing sugar intake would not have many health benefits. Try it and see how you feel!
