Making healthy food choices is important at any age. New
medical evidence shows that what you feed your body directly affects your
brain.
A "brain healthy" diet means low-fat, low
cholesterol choices combined with an abundance of antioxidant foods that are
beneficial to the brain. Better nutrition will be good for your heart and your
mind.
Many people start out the day with supplements. While it is
probably a good idea to take a daily multivitamin to give our bodies a little
extra boost, popping a pill is no substitute for a well-rounded, healthy diet.
Studies have shown that most of us do not get enough protein
rich foods, and when we do consume protein it is usually later in the day.
Scientists know that adequate proteins are vital to having an optimum thinking
process, and a protein-based meal in the middle of the day will optimize your
mental performance.
But doesn't protein usually include fat, which is bad for
you?
Yes, but not all fats are created equal. While it is true
that we want to limit the saturated fats that are found in red meats and animal
products, you can replace these "bad fats" with Omega-3 fatty acids -
also called "essential fats" - which help keep the brain operating at
its peak.
In fact, Omega-3 fats are so important to a good diet that a
severe lack of these good fats can lead to depression, poor memory, low IQ,
learning disabilities, dyslexia, ADD and many more mental disorders.
To ensure that your diet is rich in Omega-3 fats, eat plenty
of oily, cold-water fish like wild salmon, sardines, whitefish, trout, tuna,
herring, sable fish, mackerel and anchovies. Ask your doctor if you should also
take an Omega-3 supplement on a daily basis.
While the goal is to increase the Omega-3s in your diet, you
also want to decrease the intake of trans-fats - sometimes called trans fatty
acids or hydrogenated vegetable oils. Found in many processed foods, trans-fats
will pack on the pounds and provide absolutely no nutrition for your body. They
are empty calories, so whenever possible, choose fresh foods over processed.
Carbohydrates that have been refined and processed are also
considered a brain drain.
Your body will benefit if you limit the "bad"
carbohydrates, such as refined white sugar and high-sugar sweetened drinks.
Foods with high sugar content also have a high glycemic
index, which means they adversely affect the body by causing a spike and then a
sudden drop in the blood glucose and insulin levels. So the next time you are
tempted to substitute a muffin, donut or pastry for a healthy meal, remember
that your body and your brain both need high quality foods that provide fuel
for the body and brain.
But the body does need "brain booster"
carbohydrates found in whole grains, fruits and vegetables.
In fact, your mother was right when she extolled the virtues
of eating your vegetables. Even better advice is to consume both fruits and
vegetables - with an emphasis on brightly colored fresh foods.
Focus on a diet rich in fresh fruits and dark leafy
vegetables and strive for at least 4-5 servings daily.
Vegetables and fruits are packed with antioxidants and many
essential vitamins and minerals. Plus, they are low in fat and calories. Choose
foods such as kale, spinach, Brussels sprouts, alfalfa sprouts, collard greens,
broccoli, beets, red bell pepper, onion, corn, soybeans, eggplant and dark
green lettuces. Your brain will benefit from eating fruits with high
antioxidant levels including prunes, raisins, blueberries, blackberries,
strawberries, raspberries, plums, oranges, red grapes and cherries.
What other advice would Mom recommend?
Eat in moderation. Your body has to work in overdrive to
digest a huge meal, so smaller meals eaten more often is a better choice.
Nuts, also in moderation, can be a useful part of your diet.
A handful of almonds, pecans and walnuts will all provide a good source of
vitamin E, an antioxidant. Drink plenty of fluids (six 8 oz. glasses a day) and
make sure that a good portion is water. Limit caffeine and alcohol, although a
glass of red wine daily (check with your doctor) can actually be helpful, due
to the resveratrol found in dark red wines. Green tea is an excellent
substitute for coffee.
The goal with good nutrition is to have a healthier body and
mind. Your brain will benefit from a well-balanced diet and improved food
choices. When in doubt, choose fresh options, read the labels and consult with
your physician or a nutritionist.
Challenge, Exercise and Feed Your Brain
Here are some tips on how to challenge, exercise and feed
your brain.
Exercises for Good Brain Health
When most people think of exercise, they envision working
out to keep their bodies physically fit and healthy. But the brain - so
important to living a full life -- also needs an exercise regimen to stay agile
and alert.
What can you do to challenge your brain?
Activities like crossword puzzles, card games, reading,
volunteering and Sudoku puzzles will stimulate thought and cause you to retain
information and problem-solve. Even planning a vacation or attending a class
will require the brain to process new information.
More challenging activities might include mastering a
foreign language, learning a new computer program or taking music lessons.
Numerous computer programs and books feature "brain
games" that will give you a systematic mental workout. Customizing these
games optimizes the effectiveness. The key is to have differing levels of
intensity and difficulty to keep the mind engaged and working.
There are also simple exercises that don't require a book,
computer or even pen and paper. Try this: While waiting in line at the bank,
count to 100 by factors of three. If that's too easy, then go backward. Run
through the multiplication and division tables in your head. Another easy brain
stretch is to use your non-dominant hand while doing daily tasks. You might
find this frustrating at first, but you will be amazed at the results.
Whatever activities you choose, make sure that you have to
work your brain, causing it to be used in non-routine ways. This stretching
process will help create stronger memories that will provide for clearer
overall thinking.
Physical Exercise Benefits the Body and the Brain
Scientists used to believe that people were stuck with the
brain they were born with - and that individuals naturally began to lose
cognitive function as they aged. This thinking allowed people to accept memory
loss as inevitable and believe that nothing could be done about it.
However, new research shows that the brain constantly renews
itself, giving hope to those with cognitive decline.
Recent research also reveals that frequent physical exercise
has a direct correlation to brain function. Exercise stimulates stem cells to
grow new brain cells in the memory part of the brain. Enhancing blood flow to
the brain increases the density and size of the brain's capillaries, which in
turn increases the amount of oxygen to the brain.
The evidence is clear: Your body can get flabby from lack of
movement and so can your brain.
Studies show that a vigorous exercise program -- one that
gets the heart pumping fast -- causes more blood flow to the brain, thereby
providing the most benefits. However, any exercise is good, so take a walk,
work in your garden, lift weights and generally just get moving. The more you
do the better.
Adding complexity to the exercise program, such as learning
new dance steps, also helps the brain since it combines both physical and
mental stimulation. So, you can help fine-tune your mental sharpness by varying
your physical activities and by trying something new.
Finally, it's never too late to begin exercising.
If you have trouble committing to a consistent workout
program, then partner up with a spouse, family member or friend. You will be
more apt to stick with a program if there is another person counting on you.
Brain Foods for Better Health Weight management and good nutrition are both
essential to good health. In fact, new medical evidence indicates that a poor
diet contributes to brain cell damage - so what you feed your body directly
affects your brain.
A "brain healthy" diet means low-fat, low
cholesterol choices combined with an abundance of antioxidant foods. What's
good for you and what should you avoid?
Eat fresh foods, rather than highly processed foods. Drink
plenty of fluids (six 8 oz. glasses a day) and make sure that a good portion is
water. Limit any caffeine and alcohol.
Include colorful fruits and vegetables in your diet and
strive for at least 4-5 servings daily. Choose foods such as kale, spinach,
Brussels sprouts, alfalfa sprouts, broccoli, beets, red bell pepper, onion,
corn, eggplant and dark green lettuces. Fruits with high antioxidant levels
include prunes, raisins, blueberries, blackberries, strawberries, raspberries,
plums, oranges, red grapes and cherries.
In moderation, nuts - like almonds, pecans and walnuts --
can be a good source of vitamin E, an antioxidant.
Lycopene increases the blood antioxidant capacity, so foods
like tomatoes, tomato products and V8 juice are all good choices.
Most people do not consume enough protein. Opt for proteins
found in cold-water fish, like tuna, wild salmon, herring, trout, sardines and
whitefish. Conversely reduce saturated fats - such as red meats and animal
products, and replace these "bad fats" with the monounsaturated fats
in olive, canola, sunflower, safflower and soybean oils.
Decrease the intake of trans-fats (also called Trans fatty
acids or hydrogenated vegetable oils) which are found in many processed foods.
Avoid high glycemic or simple carbohydrate foods that are
really just empty calories. Sodas, sweetened drinks, cakes, cookies and other
sugary snacks will give you an initial energy boast, but they will cause your
blood sugar to fall dramatically which places stress on the body.
The goal is to have a healthier body and mind. Your brain
will benefit from a well-balanced diet and improved food choices. When in
doubt, choose fresh options, read the labels and consult with your physician or
a nutritionist.
