It's not a "risk" it's a "hazard assement".
It's not a food safety agency it's just the World Health Organization's cancer research arm.
This certainly doesn't stir up mistrust.

Blind tests specifically? Take, e.g., soda and diet soda, decant into identical containers with hidden labels, drink one, and log any effects before you check what it was. The brain is powerful. Some people experience real headaches because they think that WiFi or other RF gives them headaches. But they won't get a headache from radio waves they don't know about.
I don't intend this in a mean way. If you do find out that it's something else you could get relief from said migraines. Like the MSG folks who are probably just not drinking enough water when they go out to dinner, or are nervous about Asians or something. I once took placebo and a low dose of MDMA in a blind study and got them backwards. I was embarrassed for some reason but our brains really do construct much of what we perceive as raw sensory input.
I don't have these headaches unless it's aspartame and I really had no real opinion on the whole thing until after years of repeated "why am I getting headaches" shortly after and I revaluate what I've had and it's always triggered around aspartame. It isn't psychosomatic. I don't have a problem with regular migranes or headaches. When I do get headaches I can usually attribute them to dehydration, or stress, or some other obvious issue.
I can have suculouse with no problem. Stevia no problem. Monk fruit no problem with the added bonus of having more lucid dreams. High fructose corn syrup but I feel a bit bloated after so I try to stay away from that - but no headaches. It's always aspartame if I have more than 1 serving. So there's something there.
Why am I being gaslighted so damned hard on this forum?
Look I'm not trying to gaslight you. It's totally possible that aspartame affects you in a unique way. Maybe the headache thing is real and you are a hyper-responder. Maybe most people don't experience headaches because they're convinced it's safe. All I have to say is that you can't rule out psychosomatic effects without blind testing, and I personally don't believe untested anecdotes like yours because of my own experience with drugs and from growing up in the tail end of the MSG panic. Have a nice day, take the last word if you want.
even if you do get a headache from aspartame, so what? it says nothing about the general safety of the stuff
