Feeding
Your Brain -
Studies have shown that what we eat affects how we feel,
how we think, and how much energy we have. Memory, thinking,
and attention are strongly influenced by food.
According to neurologist
David Perlmutter (author of The Better Brain Book), “The
standard American diet is a nightmare.” He goes on to say,
“If I were to design a diet for the sole purpose of creating an
epidemic of poor brain function, accelerated brain aging, mood disorders,
and other neurological problems, it would be the one that most Americans
are already following.” ( Page 62)
Believe it or not, the
most important nutrient for the brain is fat because
the brain is actually made up of fat. The problem is, if we eat
a lot of unhealthy fats, we end up with an unhealthy brain.
Fats that support
brain health are monounsaturated fats (found in foods like
olive oil, canola oil, nuts, and avocados), and some forms of polyunsaturated
fats, including the Omega 3 essential fatty acids which are particularly
important for brain function. Omega 3 fatty acids can be found in
cold water fatty fish, deep green leafy vegetables, some grains,
and pumpkin seeds. Many people find it helpful to supplement their
intake of these essential Omega 3s by taking fish oil capsules.
The fats to stay
away from are saturated fats and trans-fatty acids. Saturated
fats are found in meat and full-fat dairy products. We need protein
in our diet, much of which comes from these sources, but limiting
the amount of saturated fat to about 10 percent of our daily caloric
intake is wise as saturated fat makes the brain cells sluggish.
According to Dr. Perlmutter, a diet high in saturated fats can result
in memory problems and moods disorders for individuals of any
age. It is not just seniors who are having “senior moments” these
days.
Trans-fatty acids
are probably the worst fats for our brains and should be
on our diet black list. These are found in nearly all processed
foods (partially-hydrogenated vegetable oil or partially-hydrogenated
vegetable shortening) and fried foods.
Trans-fatty acids are
used to increase the shelf life of food, but inhibit our learning
and performance because they make our brain cells rigid, tough,
and slow. They keep cells from being able to get nutrients, make
energy, and communicate with other cells.
Carbohydrates
are important foods for providing energy for the body .
But just as with fats, there are good and bad choices. Sugar and
white flour are two of the worst. They are simple carbohydrates
so they enter to bloodstream very quickly. They rapidly raise blood
sugar levels (which is associated with memory problems).
Sugar robs our bodies
of B vitamins and nutrients needed to support a stable nervous system
and blood sugar balance, affecting health, moods, attention, memory,
and behavior.
Be aware that there is
an extremely high sugar content in juice (eating
the whole fruit is better) and that our bodies react to artificial
sweeteners other than Stevia in the same way as sugar.
Maintaining consistent
blood sugar levels allows the brain to get the steady flow of sugar
(glucose) needed to keep it fit and functioning. Spikes and fluctuations
in blood sugar cause sugar overload which can cause an individual
to have very high, sometimes excessive energy, followed by low energy,
sleepiness, or moodiness.
Over time, chronic sugar
overload can lead to serious illnesses. William Duffy (REFINED SUGAR
The Sweetest Poison of All) says, “Excessive sugar has a strong
mal-effect on the functioning of the brain. Too much sugar makes
one sleepy; our ability to calculate and remember is lost." This
is definitely not a good prescription for learning!
Since we do need carbohydrates
for energy and to help protein (in the form of tryptophan) enter
the brain cells, complex carbohydrates will be the better choices.
These digest more slowly, enter the bloodstream more gradually,
and create a gentler rise in blood sugar. Whole grains, fruits,
legumes, and vegetables are complex carbohydrates.
Protein is extremely
important to our brain function and learning . It helps
increase serotonin in the brain which improves feelings of well-being,
hopefulness, organization, and concentration.
Many children go to school
after having a sugary carbohydrate breakfast and many teens choose
to go to school with no breakfast at all. A low sugar breakfast
and lunch with 12-20 grams of protein can make a vast difference
in a learner's performance.
Move Your Body,
Energize Your Brain -
Have you ever sat in a long meeting or seminar and found
yourself getting sleepy, antsy, and dying for a break so you could
get up and move around?
Research shows that physical
movement can enhance clarity, attention, and readiness for learning.
Physical movement increases oxygen flow to the brain, improving
alertness, concentration, and receptivity. Adding movement or physical
action to a learning activity increases recall.
At the Learning Center,
we find that integrative movements that cross the midline
of the body are extremely helpful in bringing students to a calm,
alert, and mentally and emotionally ready state for learning.
Periodic brain
breaks that involve movement throughout the school day
and homework time will also improve learning, productivity, and
attitude.
Here are some references
for fun, quick movement exercises that can be easily integrated
into the classroom, clinic, or home:

Deep breathing
and water are also great brain energizers. Deep breathing
immediately brings more oxygen to the brain and encourages relaxation,
improving thinking and focus. Water improves the electrical transmissions
in the brain and nervous system, providing energy for learning and
attention.
Words for the
Heart -
Every decision we make and everything we do is driven by
our beliefs and by our emotions. Research shows us that there is
physiological communication between the heart and the brain and
that the thinking part of the brain is highly affected by the emotional
part. We also know that our words are very powerful.
Feeling valued and in
control will dramatically impact a person's learning. Give specific
comments to students about what you observe,
like, and appreciate about them. These include:
- Have student's tell
or write what they appreciate about themselves.
True feelings of appreciation actually create chemical changes
in the brain that empower us to have more clarity and calmness,
a good combination for learning (and good health)!
- Always keep
in mind how powerful words are. Negative words and comments
can also trigger chemical changes in the brain that can stay with
a student for many hours, disrupting learning and upsetting self
esteem.
- Validate students'
efforts and achievements during as well as after completing the
task . Break tasks down into smaller, more easily achievable
units as needed so students can feel successful often.
- Help students to see
how far they have come by remembering where they began.
This helps them to see and value their accomplishment.
- Remember that a
little success goes a long way. Pushing a resistant student
in a negative way will likely get more resistance. But sincerely
celebrating even the smallest success can make that same child
sit taller and encourage him to try again.
