11 Brain-Fog Culprits You're Consuming Without Realizing It
2. Artificial Sweeteners: The Bitter Truth

Artificial sweeteners like aspartame and sucralose are common in "sugar-free" products. While they promise a guilt-free indulgence, these sweeteners can interfere with neurotransmitter function. Aspartame, in particular, has been linked to headaches and mood disturbances, both of which can exacerbate brain fog. Research suggests that artificial sweeteners can alter gut microbiota, impacting the gut-brain axis and potentially leading to cognitive impairment. For those experiencing brain fog, cutting back on artificial sweeteners and opting for natural alternatives like honey or stevia might help clear the haze.
