Why Too Much Sugar Is Bad For Your Brain, Boston University School of Medicine Study Reveals

The sugar-brain connection isn’t just a theory anymore. There’s some fairly convincing and reproducible evidence that too much sugar in the diet is linked to cognitive and brain deficits. Two new papers, both deriving data from the long-running Framingham Heart Study, bear this out. One study finds that sugary drinks are linked to pre-clinical Alzheimer’s disease: Poor memory and reduced brain volume in certain areas. The other study finds that artificial sweeteners aren’t much better—they’re linked to a greater risk of stroke and of dementia. So it seems like we’re damned if we do and damned if we don't, at least when it comes to sweetened drinks.
