Researchers believe they have uncovered a key piece of the puzzle in the connection between diet and dementia.
They linked a specific dietary pattern to blood markers of inflammation. In addition, they showed that in elderly adults who followed such a dietary pattern, brain gray matter volume was less, and they had worse visuospatial cognitive function.
"We found that people who consume less omega 3, less calcium, vitamin E, vitamin D, and vitamin B5 and B2 have more inflammatory biomarkers," study investigator Yian Gu, PhD, Columbia University and the Taub Institute for Research on Alzheimer's Disease and the Aging Brain, New York City, told Medscape Medical News.
An inflammatory dietary pattern, said Dr Gu, "is bad for both the brain and cognition."
The study was presented here at the Alzheimer's Association International Conference (AAIC) 2017.
