Forget the hype when it comes to fads for memory enhancing supplements or brain health.
Protecting memory and brain health is a matter of keeping your heart and blood vessels healthy, said Riska Platt, M.S., R.D., a New York-based nutrition consultant and volunteer with the American Heart Association.
“The brain is nourished by nutrients passed by the blood vessels,” Platt said. “If the blood vessels become clogged or impaired, that’s not good for the brain.”
Preventing a stroke, which can occur when a blood vessel carrying oxygen to the brain become blocked or bursts is crucial. When the brain can’t get the oxygen it needs, it starts to die. That can cause the brain to not function as well, or have mental cognitive decline, Platt said.
Healthy Weight, Healthy Brain
To help your heart and blood vessels healthy, Platt recommends eating a well-balanced diet, keeping your body within a healthy weight range and doing plenty of exercise to keep extra pounds off.
The D.A.S.H. (Dietary Approaches to Stop Hypertension) diet is a good model for a heart- and brain-friendly approach to eating, Platt said.
Platt cautions patients to stay away from trans fats. Trans fats – also called “partially hydrogenated oils” on food packaging, raise your bad cholesterol(LDL) levels and lower your good cholesterol (HDL) levels and increase your risk of developing heart disease and stroke.
There’s No Magic Food
While there’s no one magic food that can prevent problems with brain health, ongoing research points to promising signs about Vitamin D and omega fatty acids, Platt said.
Omega-3 fats, found in oily fish such as salmon or mackerel, are also believed to lead to better brain functioning, Platt said. And some research has shown that omega-3 fatty acids could decrease the risk of abnormal heartbeats (arrhythmias), slow the growth of plaque in the arteries (atherosclerosis)and decrease triglyceride levels.
Studies have also highlighted possible benefits from vitamin D as a way to ward off stroke and cognitive impairment.
“The No. 1 thing to do is have a well-balanced diet,” Platt said. “Don’t just focus on one food, because nutrients work together.”
