Not really, aspartame hasn't been shown to have any health effects at normal levels or even very high levels for that matter.
		
		
	 
yes but people read how this stuff is made and get it into their heads its terrible, and a few people who say drunk 10 litres of coke a day feel ill, and it gets the blame, because people are stupid.
For instance SO many people complain about sucralose, my mother included who comments anytime I use it on how i'm basically just eating chlorine, which is insane.
Basically they use chlorine to remove something from one substance and react with another substance and 99.9% of the chlorine will be removed and its essentially completely safe.  The fact that chlorine is added to our drinking water matters not,  this stuff because chlorine is used in its making just "has" to be lethal.  People don't use their brains, see a word they think is bad and go barmy telling everyone the stuff is bad for you.
Frankly you breathe in, absorb through your skin, eat so much "bad" stuff all through your life anyway, the body is very very good at dealing with that, you have cynanide in your naturally, just not a lethal amount, trace amounts but its there.  I wish people would get passed all this nonsense as it bores me to tears.
Omega 3 is one of the most key substances to humans, its used for untold numbers of things in your body, your brain is made up of omega 3, its probably the single key most important substance to us,  yet if you ate enough of it you'd turn into a fat unhealthy whale.
