Kinda funny that this person correctly explains the silly hysteria people had over E-numbers and then in the same comment spreads some silly hysteria over aspartame.

Aspartame is E951, by the way.

The science teacher’s comment is far removed from the evidence presented in that link:

with a can of diet soft drink containing 200 or 300 mg of aspartame, an adult weighing 70kg would need to consume more than 9–14 cans per day to exceed the acceptable daily intake

That was good information, thank you.

For example, with a can of diet soft drink containing 200 or 300 mg of aspartame, an adult weighing 70kg would need to consume more than 9–14 cans per day to exceed the acceptable daily intake, assuming no other intake from other food sources.

You'd be running to the bathroom every 5 minutes too
