The Claim

Consumption of aspartame at doses within the acceptable daily intake (ADI) is associated with increased neuroinflammation and accelerated cognitive decline in individuals during critical developmental periods or with comorbid metabolic conditions such as obesity, based on synthesized evidence from in vitro, animal, and limited human studies.

In plain English

Eating or drinking things with aspartame, even in amounts considered safe, might be linked to more brain inflammation and faster memory or thinking problems in kids, teens, or people who are overweight or have metabolic issues.

What the research says

1 study
  1. Study: Artificial sweeteners and brain health: critical evaluation of aspartame impact on neurovascular and cognitive consequences

    This study found that even the safe amount of aspartame we're told is okay to drink every day might still harm the brain in kids, teens, or people with obesity, making them more likely to have brain swelling and memory problems over time.
