Healthy food and Memory 

There's no denying that as we age chronologically, our body ages right along with us. But research is showing that you can increase your chances of maintaining a healthy brain well into your old age if you add these "smart" foods to your daily eating regimen.

Here are some foods that researchers think will keep your whole body—including your brain—healthy.

Oil-based salad dressings

“The data support eating foods that are high in vitamin E and this includes healthy vegetable oil-based salad dressings, seeds and nuts, peanut butter, and whole grains,” says Martha Clare Morris, ScD, director of the section on nutrition and nutritional epidemiology in the Department of Internal Medicine at Rush University, in Chicago. The benefit has been seen with vitamin-E rich foods, but not supplements, she says.

A potent antioxidant, vitamin E may help protect neurons or nerve cells. In Alzheimer’s disease, neurons in certain parts of the brain start to die, which jump-starts the cascade of events leading to cognitive deterioration.

 

 

 

 

 Fish

Salmon, mackerel, tuna, and other fish are rich in heart-healthy omega-3 fatty acids, including docosahexaenoic acid (DHA). In the brain, DHA seems to be very important for the normal functioning of neurons.

Another plus: Eating more fish often means eating less red meat and other forms of protein that are high in artery-clogging saturated fats.

 

 

 

 

Dark green leafy vegetables

Kale, collard greens, spinach, and broccoli are good sources of vitamin E and folate, Morris says.

For example, one cup of raw spinach has 15% of your daily intake of vitamin E, and 1/2 a cup of cooked spinach has 25% of your daily intake.

Exactly how folate may protect the brain is unclear, but it may be by lowering levels of an amino acid known as homocysteine in the blood. High levels of homocysteine may trigger the death of nerve cells in the brain, but folic acid helps break down homocysteine levels.

High homocysteine levels have also been linked to an increased risk for heart disease.

Avocado

This creamy treat is also a rich source of the antioxidant vitamin E. Researches suggest that foods rich in vitamin E—including avocado, which is also high in the antioxidant powerhouse vitamin C—are associated with a lower risk of developing Alzheimer’s.

 

 

 

 

Sunflower seeds

Seeds, including sunflower seeds, are also good sources of vitamin E.

One ounce of dry-roasted sunflower seeds contains 30% of your recommended daily intake. Sprinkle them on top of your salad to give your brain a boost.

 

 

 

 

Peanuts and peanut butter

Although both are high in fat, peanuts and peanut butter tend to be a source of healthy fats. And they are also packed with vitamin E.

Both foods may help keep the heart and brain healthy and functioning properly. Other good choices are almonds and hazelnuts.

“There has been some very good research that diets that are high in healthy fats, low in saturated fat and trans fats, and rich in whole grains, green leafy vegetables, and nuts are good for the brain and the heart,” says Maria C. Carrillo, PhD, senior director of medical and scientific relations at the Chicago-based Alzheimer’s Association.

 

 

 

 Red wine

Studies have shown that people who consume moderate amounts of red wine and other types of alcohol may be at reduced risk for Alzheimer’s disease, but it may be that there is something else that tipplers do or don’t do that affects their risk of developing Alzheimer’s, Carrillo says.

“People who drink alcohol or eat healthy may be healthier in other aspects of their life, so it is difficult to disentangle whether it’s the healthy diet that protects them versus other healthy behaviors.”

 

 

 

 

Berries

The latest research presented at the National Meeting of the American Chemical Society in Boston found that blueberries, strawberries, and acai berries may help put the brakes on age-related cognitive decline by preserving the brain’s natural “housekeeper” mechanism, which wanes with age.

This mechanism helps get rid of toxic proteins associated with age-related memory loss.

The compounds in blueberries, known as flavonoids improve memory, learning and general cognitive function, including reasoning skills, decision making, verbal comprehension and numerical ability. In animal studies, researchers have found that blueberries help protect the brain from oxidative stress and may reduce the effects of age-related conditions such as Alzheimer's disease or dementia. Studies have also shown that diets rich in blueberries significantly improved both the learning capacity and motor skills of aging rats, making them mentally equivalent to much younger rats.

Whole grains

Fiber-rich whole grains are an integral part of the Mediterranean diet, which is also loaded with fruits, vegetables, nuts and seeds, olive oil, and wine.

Research out of Columbia University Medical Center in New York City shows that this diet may be linked to lower risk of the mild cognitive impairment that can progress to Alzheimer’s disease.

“We don’t eat foods or nutrients in isolation, we eat in combination with other foods so there is value in dietary patterns,” says Nikolaos Scarmeas, MD, an associate professor of neurology at Columbia University, who conducted the studies.

This type of diet may reduce inflammation, oxidative stress, and other vascular risk factors such as high blood pressure—all of which may have a role in increasing risk for brain and heart diseases.

 








Exercise

Okay you can’t eat it, but research suggests that regular exercise is as important, if not more so, as what you eat when it comes to memory-saving lifestyle changes.

Experts all stress that getting regular exercise is also an important part of the equation when it comes to staving off many diseases, including Alzheimer’s.

The bottom line?

“We can‘t go out and say, ‘Eat these things and you are protected from Alzheimer’s,' but there is almost no downside to increasing your physical activity and consuming a diet rich in whole grains, vegetables, fish, healthy oils, nuts, and seeds,” Morris says.
