Adding a few servings of whole grains linked to slower memory decline in black people
Black people who eat more foods with whole grains, including some breads and cereals, quinoa, and popcorn, may have a slower rate of memory decline compared to Black people who eat fewer whole grain foods, according to a study published in the November 22, 2023, online issue of Neurology, the medical journal of the American Academy of Neurology. The researchers did not see a similar trend in white participants.
The study does not prove that eating more whole grains slows memory decline; it only shows an association. The study found that among Black people, those who ate the most whole grains had lower levels of memory decline equivalent to being 8.5 years younger than those who ate small amounts of whole grains.
The study involved 3,326 people with an average age of 75 without dementia. Of all participants, 1,999 people, or 60%, were Black. They were followed for an average of six years.
