Mindsip insights from this episode:
Recognize sweeteners' link to cognitive decline despite health adjustments
The association between sweeteners and cognitive decline persisted even after researchers statistically controlled for other health factors like being overweight or having cardiovascular disease.
Critique intervention studies on sweeteners for cognitive effects
While many intervention studies on sweeteners show no negative cognitive effects, they are often of poor quality with improper controls, making it hard to draw strong conclusions.
Avoid xylitol and erythritol to protect cognitive health
Of the sweeteners analyzed, xylitol and erythritol showed the greatest association with cognitive decline, warranting a 'safer than sorry' approach until more data is available.
Limit non-nutritive sweeteners to protect cognitive health in diabetics
The link between non-nutritive sweeteners and cognitive decline is significantly stronger in people with compromised metabolic health, such as type 2 diabetes.
Limit diet drink intake to avoid high consumption risks
Consuming just a single diet drink per day, containing 80 to 150 milligrams of sweeteners, is enough to place someone in the study's moderate to high consumption group.
