Is Aspartame harmful?

As I recall (and googling Aspartame should get more info), Aspartame was shown to cause cancer in lab rats. But the quantities needed to cause that cancer were so huge it was equivalent to a human consuming pounds of the stuff daily.

I have seen nor heard of any evidence that Aspartame is dangerous when used moderately. However, a new substitute, Splenda has appeared fairly recently. Made from sugar but without the calories it may be a better choice.

I've seen those findings - and the truth behind them - too. I do not find any reputable [medical] sites giving good evidence that it is harmful to humans in reasonable doses.

I would tend to agree with Scott and Rick -- though it can be difficult to separate the truth from the hype. There are countless webpages devoted to the dangers of Aspartame. Most recently, it has even been suggested that it can reactivate otherwise dormant Lyme in chronic sufferers of such. Who knows...
One possible natural alternative -- to the best of my knowledge, considered generally safe for diabetics -- is an herb called Stevia, used as an alternative to table sugar. It is ultimately far sweeter than sucrose, but is sometimes reported as having a slightly bitter, or "liquorice" aftertaste. I have never tried it myself, prefering to use honey, but it is available in any good whole-foods market.

I don't know about these studies about cancer etc being attributed to aspartame but I CAN vouch for the fact that people CAN be allergic to aspartame! I am one of those people. Whenever I drink a lot of flavored water with aspartame, I get an excruciating headache that stubbornly refuses to be eased by Tylenol. My doctor finally figured out the association of the headaches and the aspartame and now I avoid it whenever possible. I use Splenda and try to purchase products made with Splenda instead of nutra-sweet (uses aspartame). A LOT less headaches now!

It is harmful but just like the drug companies they are more concerned about making their millions than if some people have bad effects from it. It turns to formaldahyde in your system. I know lots of people who insist on drinking diet soda and using their Splenda and other sweeteners and they have very poor health....shakes, poor memory, vision problems, migraines, etc. That worsened more after they gave up the sugar for aspartame.

Stevia is a good alternative. Agave nectar and some Asian sweetener that I can't recall the name are suppost to be the best alternatives.

Also there are a few things that are good for diabetics but you have to monitor your insolin more and keep up with doctor check ups if you try these since they can normalize your sugar. These are what I remember
