DASH Diet Said to Help Preserve Memory as People Age
Maintaining brain health does not always have to start with expensive supplements or specialised therapy. Recent research shows that everyday dietary patterns play a major role in maintaining memory. One of the diets most discussed by researchers is the DASH Diet. Initially, this eating pattern was developed to help lower blood pressure. However in recent years, researchers have identified additional benefits; this diet also has the potential to slow cognitive decline, including memory loss.
One study led by researchers at NYU Grossman School of Medicine found that following the DASH diet in midlife was associated with a lower risk of later-life memory decline. The study involved 5,116 women who were followed for over 30 years as part of the NYU Women’s Health Study.
The results showed that women who most consistently adhered to the DASH diet had about a 17% lower likelihood of reporting memory and cognitive function problems than those with unhealthy eating patterns. The findings were published in the scientific journal Alzheimer’s & Dementia.
Another study published in Neurology also found similar results. Participants following the DASH eating pattern experienced slower cognitive decline than those who did not implement it.
Researchers concluded that vascular health is closely linked to brain health. When blood pressure is controlled and inflammation reduced, blood flow to the brain improves. This condition helps preserve memory function in the long term.
The DASH diet does not require people to follow complex rules. It involves increasing nutrient-dense foods and reducing foods that are unhealthy.
Some of the main principles of this eating pattern include increasing consumption of vegetables and fruits, choosing whole grains, consuming fish, legumes, and lean proteins, and reducing salt, sugar, and saturated fats.
This combination of foods is known to help protect heart and blood vessel health. Since the brain relies heavily on good blood flow, the benefits extend to cognitive function.
Although the DASH diet shows promising results, experts emphasise that diet is only one part of a healthy lifestyle. Regular physical activity, sufficient sleep, and maintaining mental health also play key roles in preserving memory.
However, many researchers agree that a simple dietary change can be a realistic first step. Compared to complex medical interventions, adopting a DASH-style eating pattern is relatively easy to implement and can have long-term benefits for brain health.
With more research supporting it, the DASH diet is now recognised not only as a strategy for lowering blood pressure but also as an eating pattern that may help preserve memory into old age. (NYU Langone Health/National Institutes of Health/Z-2)
More than 70 studies show that fasting for 8–24 hours does not affect memory, focus, or reasoning in adults. However, its effects differ in children and adolescents.
Japanese research found that bitter compounds in dark chocolate and berries can enhance memory by activating the brain’s chemical systems.
