“I recommend limiting your intake of red meat and processed foods because they are inflammatory and can increase the risk of plaque in the brain that can contribute to dementia,” says Dana Ellis Hunnes PhD, MPH, RD, author of Recipe for survival.

In fact, animal research of Ohio State University showed that regular consumption of processed foods may lead to more rapid memory loss in aging populations. The same results mention that replacing these foods with omega-3 rich options (as mentioned above) can significantly improve your brain health.

“Ensuring an adequate intake of B vitamins (thiamin, B12, etc.) is crucial because they can be linked to neurological (including brain) changes,” says Hunnes.

For example, a recent study found that Vitamin B12 deficiency could contribute to poorer cognitive function. You can find B12 in most animal products such as meat, dairy, and eggs. If you don’t eat meat products, you can always supplement with a B12 pill.

A study found that young and older adults who ate blueberries had better memory and attention, as well as better blood flow to the brain.

They also found that older adults who regularly ate strawberries and blueberries had better memories than those who didn’t eat berries.
