I drink one can of diet soda a couple of times a week and was starting to get worried lol
If you don't suffer from Phenylketonuria, Phenylalanine is a harmless amino acid. And should you suffer from that you will know.
Methanol on the other hand is known to be damaging. However if you drink beer you consume small amounts of methanol. Same for most alcoholic drinks. But these small amounts are very high compared to what you get from aspartame.
Which is why I was never worried too much about aspartame in small amounts. Just don't make it your main hydration source.
One small doubt in my comparison is that one of the main treatments for methanol poisoning is to give pure ethanol. Since it competes with the same enzymes, alcohol dehydrogenases, that break Methanol down into toxic compounds.
If you consume aspartame without alcohol there's no ethanol to compete.
But it's still small amounts, do with that what you will.
If you've ever been to California you will know that everything may cause cancer. The question is how much. And I still think Aspartame is the least of your worries if you don't live an extremely healthy lifestyle already. I.e. zero sugar, zero alcohol, no red meat, no processed food, no cigarettes...
