The researchers also reported that higher Dietary Inflammatory Index (DII) scores were “associated with smaller total gray matter volume … and larger lateral ventricular volume,” both of which are associated with increased risk of dementia.
“Systemic inflammatory processes in the body, including the brain, can be influenced by diet, leading to its important contributory role in brain aging,” the researchers observed.
“In our study, we found evidence of an association between DII scores and global markers of brain volumes and vascular brain injury, which are early markers of dementia,” they wrote.
“Moreover, previous studies have shown associations between the DII and risk factors of dementia.”
What’s the bottom line? The researcher wrote, “Our findings indicate [the] potential for prevention by dietary modification.”
The findings were published in Alzheimer’s & Dementia.
