Brain Food - Eat to Nourish
Your Brain!
The human brain is a complex mixture packed with tiny, fragile
cells easily damaged by free radicals, too much alcohol, raging
blood sugar and cloying cholesterol. These very same things
make your cardiovascular system run poorly. Unlike the body,
however, the brain does not recover as rapidly from slights,
injuries, abuse or neglect as other body parts such as your
heart. When a nerve cell dies, it remains dead.
You can save your brain before it is too late. You do so
by “feeding your head”. This sounds rather funny,
I know. Actually, it is fascinating how food affects your
brain.
Your brain and your heart have a lot in common. If your arteries
clog-up with cholesterol, and oxygen cannot get to your brain,
your thinking process suffers which in turn increases your
chances of memory loss.
If heart disease, high blood pressure and diabetes become
out of control, you could damage blood vessels in your brain.
This will set you up for dementia, which goes hand in hand
with Alzheimer’s disease. To sum this up, what hurts
your heart hurts your brain as well.
People with a clustering of risk factors at middle age are
encouraged to modify them by eating a healthy diet and getting
regular exercise. Evidence now shows that doing so will help
control both cardiovascular disease and diabetes, preserving
the power of your brain as a bonus.
The DASH Diet
A good way to achieve disease control and lose weight is the
DASH diet. “DASH” stands for, “Dietary Approaches
to Stopping Hypertension”. Combined with regular exercise,
you will not only be heart smart, you will be “head
smart” as well! See also, The DASH Diet and DASH Diet
Recipes.
The DASH diet is a daily low-fat combination of the following:
• Eight to ten servings of fruits and vegetables
• Two or three low-fat dairy products
• About six ounces of less of protein from meat or fish
• A small portion of nuts
• Seven or eight servings of whole grain foods
This diet has proven successful in lowering blood pressure
as effectively as medication. Results show is as little as
two weeks in people with moderately high blood pressure. Geared
to people eating a diet of 2,000 calories a day, you can modify
the diet if you wish to lose weight. Simply reduce the calorie
content by two or three hundred calories a day. (Note that
to lower your disease risks; you need to lose just ten-percent
of your body weight). In addition, this diet contains a variety
of heart and brain-protective nutrients, including antioxidants,
omega-3 fatty acids and vitamins C and D.
While resting, your brain is using up approximately 20-percent
of your total body supply of oxygen. Processing that oxygen
comes with a high price tag: One of its by-products is those
free radicals that can damage and prematurely age delicate
cells, including your neurons. Neurons are the specialized
cells that carry messages to your brain. A few antioxidant
rich foods are blueberries, strawberries and cooked spinach.
Vitamin E is a potent antioxidant as well. Vitamin E may protect
against dementia. The recommended daily dose of vitamin E
is 400 IU. Even doctors who are not fond of supplements as
nutrients state vitamin E to be beneficial as a daily supplement
to your diet.
Other vitamins play an important role in the health of our
brains. A daily recommendation of Vitamin C, about 100 to
500mg is beneficial to the brain as well. In addition, B12
appears to protect your neurons. B12, in its natural form,
is in animal products. Those past the age of 50 benefit from
a B12 supplement. Once past this age, the body loses its ability
to absorb natural B12. An excellent source of B12 is fortified
cereal. Folate aids in short-term memory loss, dementia and
acts as an antidepressant. Fruits and vegetables are rich
in this nutrient.
Fish – Truly a
Brain Food
The omega-3 fats in fish might protect you from depression,
which could keep the memory center of your brain from shrinking
– literally. About half of those with major depression
release large amounts of glucocorticoids into their blood
stream. These are the same steroids released by prolonged
stress. The longer the depression, the more severe the shrinkage.
The rate of depression in the U.S. has increased 100-fold
in the past century. This increase coincides with Americans
deserting omega-3 fatty acids in favor of omega 6 fatty acids,
the kind found in soybean and corn oil. This is the major
oil in processed and junk foods. Boost your omega-3 intake.
Eat fish two or three times a week and switch to olive oil
in your cooking and baking.
Quick Tips:
• Strawberries may actually reverse memory loss.
• Low-fat cheese frights a brain robber; high blood
pressure.
• Although the research on diet and the brain is very
new, vitamin E is emerging as a hot prospect for brain-health.
• Have a high carbohydrate breakfast. Tired heads need
a glucose wake-up call. Suggested: cereal, pancakes and syrup,
waffles, milk.
• The omega-3 fats in fish may protect you from depression,
which could shrink your memory center.
