A lot of us use artifical sweetners such as Sweet N' Low, Splenda and Equal. I use them in my coffee but not in tea. This article leads us to believe that Aspartame is harmless and even goes as far as to insinuate that it's healthy for us.
"Ajinomoto believes that the time is right to remind the industry that Aspartame tastes just like sugar and that it's made from amino acids - the building blocks of protein that are abundant in our diet"
The reality is that it's far from healthy but actually dangerous. There's a huge laundry list of bad side effects including but not limited to: (these are just the tip of the iceberg)
blindness in one or both eyes
decreased vision and/or other eye problems such as: blurring, bright flashes, squiggly lines, tunnel vision, decreased night vision
pain in one or both eyes
headaches, migraines and (some severe)
dizziness, unsteadiness, both
confusion, memory loss
Aspartame changes the ratio of amino acids in the blood, blocking or lowering the levels of serotonin, tyrosine, dopamine, norepinephrine, and adrenaline. Therefore, it is typical that aspartame symptoms cannot be detected in lab tests and on x-rays. Textbook disorders and diseases may actually be a toxic load as a result of aspartame poisoning.
Clicky for the entire list of side effects. I think I'm switching back to sugar FULL TIME!
