WASHINGTON, DC—Adults age 40-plus who say they eat healthy foods most of the time are twice as likely to rate their brain health and mental sharpness as “excellent” or “very good” compared to adults who rarely eat a healthy diet (77% vs. 39%), according to a new AARP consumer survey on brain health and nutrition. But only about one-third (35%) of adults surveyed reported eating nutritious and well-balanced meals “most of the time (5-7 days).”
“Maintaining a healthy diet is vital for good brain health and it is unfortunate that not enough people are aware of the risks associated with poor nutrition,” said Sarah Lock, AARP Senior Vice President for Policy, and Global Council on Brain Health (GCBH) Executive Director. “The results from this survey, along with the latest GCBH report on “Brain Food,” show how certain dietary changes can provide a good foundation for improving brain health.”
Key findings from AARP’s 2017 Brain Health and Nutrition Survey:
- Significantly more adults who ate the recommended daily amount of fruits and vegetables reported better brain health than those that did not. Most adults, however, are not getting the daily recommended servings in all five food groups. Moreover, one-third did not consume the recommended amount in any food group.
- Nearly nine in 10 adults said they are likely to eat healthier if they knew it would lower the risks of cognitive decline (87%), heart disease (88%), and diabetes (88%).
- More than 60% of adults age 40 and older said that they would eat more fish, less red meat, and lower their dairy fat intake if they knew it was good for their brain health.
- Adults ages 40-54 were significantly more likely to cite barriers to healthy eating compared to adults ages 65 and older.
“The most common reasons people gave for not eating healthier included that it was too difficult, too expensive, they weren’t a “healthy foods type” of person, or their family wouldn’t like the taste,” said Lock. “Half of adults said they would be more likely to change their diet if their doctor told them to do it but only 37% said their doctor has spoken to them about their diet.”
New Recommendations on Nutrition’s Role in Brain Health
Long-term healthy eating habits promote good brain health, according to new consensus recommendations released separately today by the GCBH. The new report finds that a plant-based diet rich in fruits and vegetables is associated with better brain health, and eating fish and other seafood seems to benefit cognitive function. However, excessive alcohol, high levels of saturated fats, and high salt intake are all harmful to brain health. A heart-healthy diet is also a brain-healthy diet because high blood pressure, high cholesterol, and diabetes—all common conditions influenced by diet—harm both cardiovascular and cognitive health. And contrary to recent reports, GCBH recommends a healthy portion of skepticism for people who are drinking coffee, tea, and red wine expecting a brain health benefit until more evidence is developed.
