Boost Brain Power With These Brain "Super" Foods-The top 10 foods that make you smarter...and healthier
By: Jillian McMullen
When it comes to
food, you have a wealth of delicious choices. And each one not only
tastes good but also supplies unique health benefits. From
blueberries to dark chocolate, leading nutritionists and physicians
are pointing to certain foods that enhance brain power and, they
say, a heart-healthy lifestyle.
Although there’s no
conclusive research about the healthful brain benefits of particular
supplements, food sources rich in vitamin E and Omega 3 fatty acids
may provide benefit, says Jillian McMullen, R.D., LD/N, Outpatient
Clinical Dietician with Mayo Clinic.
Vitamin E-rich foods
include vegetable oils, nuts, seeds, green leafy vegetables, and
whole grains. Omega 3-rich foods include fish, walnuts and flax
seeds.
“We also know that adequate amounts of B
vitamins are essential for brain function,” says McMullen. “Some
studies suggest a protective role of vitamins B9 (folic acid) and
B12, but more research is needed before we can recommend these
supplements. It doesn’t hurt to eat foods rich in folic acid such as
green, leafy vegetables, fortified breads and cereals, and dried
beans, as well as those chocked full of vitamin B12 like fish, meat,
eggs, cheese and chicken.”
It’s All About Balance
There’s no
denying that as we age, our body (and brain) ages right along with
us. Getting older brings some risk of cognitive problems such as Alzheimer’s disease or dementia. There’s also increased brain function risk from
certain diseases like hypertension, diabetes and obesity that can
cause damage to the brain.
“Theoretically, we can
control these diseases and keep our brain healthy unlike old age or
genetic factors that we can’t control,” says Floyd Willis, M.D.,
family medicine practitioner and creator of Mayo Clinic’s “LiveWell.
ThinkWell.” program.
It all ties together, Willis says. People who have the most risk of strokes
are those with hypertension, diabetes and obesity. “Often, people
don’t associate the truism that as goes the heart, so goes the brain
(and kidney). The impetus of the Mayo ‘LiveWell. ThinkWell.’ healthy
brain program is about maintaining a healthy balance and healthy
lifestyle.”
Dr. Willis created the community outreach
program offered through Mayo’s Memory Disorder Clinic to educate
African-Americans about healthy brain aging and memory disorders.
African-Americans may have higher risk for Alzheimer’s disease
because they have a higher incidence of some medical conditions
associated with dementia,
according to the Alzheimer’s Association.
The program provides information to seniors and their families about
memory disorders and brain aging, including tips on how to keep the
mind healthy. Research is showing that you can increase your chances of
maintaining a healthy brain well into old age if you add “super”
foods to your daily diet. Blueberries have been found to help protect the brain and animal studies have
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.
“But, we can’t conclude that antioxidant-rich foods like
blueberries, strawberries and spinach will have the same age-related
reversal of brain deficits in humans as those they found in rats.
The American Dietetic Association is currently studying the effect
of strawberries, blueberries, prunes, spinach and fatty fish, and
may find positive benefits to short term memory,” says McMullen.
Whether or not the foods are brain super foods, they’re
heart healthy and a great part of a balanced diet, she says. “A diet
rich in a variety of fresh fruits and vegetables, whole grains, lean
meats and low-fat dairy is essential to overall health and energy.”
Healthy
Food for a Healthy Life
Carol Albanesi, Director of Food Services and a registered
nurse for
Flagler
Hospital
, agrees. “The
foods we’re talking about are foods that are necessary and
appropriate for a healthy diet. There’s not any true super food. A
healthy diet has to be part of a healthy lifestyle that includes
getting enough sleep (six to eight hours a day) and eating right. By
that I also mean eating breakfast, not skipping meals and adding
several small snacks during the day.”
Albanesi suggests that by eating healthy food, getting
enough sleep and exercising three to five times a week you’ll
increase your optimum health. All of these activities, including
eating brain boosting super foods, bring oxygen to the brain by
expanding blood vessels for increased blood flow to the brain.
“Your circulatory system feeds your cells and pulls away
toxins,” she says. “That’s why you need to increase blood flow with
these activities. Exercise is particularly good because it increases
blood flow, lowers blood pressure and keeps your body healthy.”
Beans, she says, are a great food source because they’re a
good carbohydrate and protein source, they’re inexpensive and they
stabilize your glucose during the day. Drinking water is also
important. Albanesi also suggests six to eight 8-ounce glasses of
water a day.
The Top Ten Brain Boosting Foods
Sally Clifton, MSH, RD, LD/N, at
Shands
Hospital
,
offers her top ten brain super food picks:
1. Coffee – The caffeine and the coffee bean itself have been shown to have some
antioxidant properties, she says. Most of the benefits for boosting
brain power come from the caffeine. Suggested serving: no more than
two or three cups a day.
2. Tea – Freshly brewed green and black tea have antioxidant properties and
some caffeine that dilates blood vessels and increases the blood
flow to the brain, enhancing memory focus and mood. “It’s temporary
so everyone should judge the amount,”
Clifton
says. “The tea contains catechines
that are the antioxidant properties; flavored tea doesn’t have
caffeine.” Suggested serving: no more than two or three cups a day.
3. Blueberries – Blueberries are one food that really stands out, she says, because they
have a certain antioxidant that prevents oxidative stress to help
reduce age-related diseases. “Over time, because you’re exposed to
the environment, you’re more exposed to free radicals. That’s why
it’s so important that athletes take in fruits and vegetables.”
She
advises adding a variety of fruits to your diet. An easy way to add
them is putting a cup in your smoothie, shake, yogurt or on cereal.
Suggested serving: 1 cup a day.
4. Wild or farm-raised salmon – Wild salmon tends to be leaner and purer than farm-raised but both
are good, she says. Salmon is rich in Omega 3 fatty acids and
contains anti-inflammatory substances that ultimately aid in blood
flow and brain activity, lowering dementia and stroke risk and
enhancing memory. “Salmon even keeps the blood flowing in the very
small capillaries in the brain,” she says. Suggested serving:
4-ounces two or three times a week grilled, baked or broiled.
5. Nuts and seeds – Nuts and seeds are rich in vitamin E that boosts brain function and
corresponds with less cognitive decline. Nuts and seeds also offer a
large dose of monounsaturated fat that is heart healthy and promotes
blood flow. A caveat is that nuts and seeds are very high in good
fat, so limit the amount. Choose unsalted if you have hypertension.
“Almonds, walnuts and peanuts are very good but choose a variety,”
she says. Suggested serving: about one-fourth cup or one ounce a
day.
6. Avocados – Although avocados got a bad rap for having a lot of fat several years
ago, the green fruit is actually very healthy all around. They’re
packed with monounsaturated fat but it’s good fat. Avocados also
have a lot of antioxidants and some amino acids (protein), help
lower blood pressure and help reduce inflammation. “I suggest
putting them on a sandwich, in a salad or on your salmon for a
double brain boost.” Suggested serving: one-quarter to one-half of
an avocado daily.
7. Whole grains – Whole grains like whole wheat bread, pasta, cereals, wheat germ and
brown rice create good blood flow because they have more intact
nutrients including vitamin E, antioxidants, fiber and some have
Omega 3 fatty acids. “Blood flow is crucial because it helps keep
the integrity of cells in the brain,” says
Clifton
.
8. Pomegranate
juice – Although juice has been maligned because it’s packed with sugar,
pomegranate juice is full of antioxidants and a small amount of
sugar helps with immediate energy. “Stick to about 2 ounces of
natural fruit juice per serving. A way to do that is to mix the
juice with sparkling water or sprite for a flavor boost. You can add
it to water several times a day and eat a piece of fruit,” she says.
Suggested serving: about 6 to 8 ounces a day.
9. Beans – All kinds of beans including black beans, kidney beans and lentils
offer a lot of fiber and help stabilize your glucose levels
throughout the day, allowing your brain to better use the food for
fuel. Suggested serving: one-half cup a day.
10. Dark chocolate – This decadent food has powerful antioxidant properties and also has
a small amount of caffeine, a natural stimulant that aids with focus
and concentration. Dark chocolate also stimulates production of
endorphins that help improve mood. For a double health surge, try
chocolate covered blueberries. Suggested serving: one-half to one
ounce a day.
Back to Basics
“The
key is a healthy diet and eating small meals throughout the day to
boost brain power because the food is giving you small energy
boosts,” says
Clifton
.
“I most often work with people to establish balance. Some
people will drink coffee all day long. The unhealthy aspect of
drinking this much coffee is that the caffeine suppresses appetite.
So they deprive their body during the day and then overeat at night.
That’s not a balanced, healthy way of eating.”
Almost all of the super foods can easily be
incorporated into one meal such as a salad or wrap. You may be
thinking diet, but by adding these foods you’re also sharpening your
thinking.
Clifton
agrees that getting back to basics with exercise, getting eight
hours of sleep a night (eight is more beneficial than less) and
using meditation and relaxation exercises like yoga all help
increase your body awareness and health.
“With meditation and relaxation, you’re
breathing better and relieving tension and stress. It all goes
together, but eating right does take some planning. The bonus to
taking time to plan your meals is that you’ll gain more health
benefits. A good idea is to get your spouse and children involved.
It’s more fun and motivating if you and your family cook together.
Online resources for healthy recipes include eatright.org, the
official website of the American Dietetic Association, and
cookinglight.com,” she says.
