Your Brain
Your brain is a three
pound control center of your mind and body requiring
about 20% of the blood pumping out of your heart with each and every
beat. For optimal and long-term power, your brain requires a
continuous stream of nutrition and oxygen. Research on how the brain
endures the damaging effects of everyday life shows that attention to nutrition
can increase your chances against deterioration of your brain at any
age.
Brain cells communicate with your other cells and keep mental
activities in never-ending motion. These very busy cells consume up to
five times more energy and need at least five times more blood sugar than any
other part of your body. Keeping blood vessels clear of impediments
improves brain function. The same kinds of nutrients that can boost
cardiovascular health and keep blood flowing properly also aid your brain's
nourishment.
Among the nutrients your brain craves are mixes of fatty
acids that are incorporated into your brain cells' membranes. These
delicate membranes are crucial for communication among neurons, nerve cells in
your brain. By the time you mature, your brain contains a complicated web
consisting of about 100 billion neurons linked by trillions of
connections.
Within this complex system, about one-fourth of your
brain's weight is fat, called lipids. Lipids serve many important roles,
which include insulating nerve fibers and acting as building blocks of cell
membranes surrounding neurons.
The most important fats you need to
consume to increase cognitive processes are omega-3 fatty acids.
These are best obtained by eating fish, nuts, seeds, and flax and hemp
oils.
Fats that should be avoided are trans fatty acids, found in
many refined, processed and fried foods. These actually have
detrimental effects on your brain. Hydrogenated oils added to many cakes,
cookies, boxed cereals, breads, peanut butter, margarine, microwavable meals,
all chips, and about half of all refined foods sold in containers are slow
poisons. These possess physical characteristics that, when incorporated
in cell membranes, radically alter their performance.
One hour after
eating a fatty meal, blood cells begin to stick together. Within six
hours the "clumping" is so severe that blood flow actually stops in small blood
vessels. In addition, eating fatty foods decreases the bloods oxygen
supply by 20%. The electrical communications between cells can be
hindered. The flow of the bioelectrical current crucial to proper neuron
function can be altered. Membranes can stiffen making them less flexible
and potentially slowing your mental abilities as the harmful fats interfere
with the normal flow of molecules in and out of brain cells.
Kids
that eat too many of the fatty treats sold in supermarkets like candy bars,
pastries, etc, may consequently suffer learning difficulties.
Your
brain does require a steady, large supply of blood sugar. These are
easily supplied by eating whole grain foods like brown rice, whole wheat and
oats. B vitamins are also a good bet. In fact, they are called the
mental health vitamin. But, metabolizing excess sugar depletes B vitamins
in your body and at times there's not enough left over to produce great mental
and emotional chemistry. B vitamins are found in lean meats, whole grain
foods, dried beans and peas, sunflower seeds and nuts, green leafy vegetables,
cheese, yogurt and tofu.
Your brain's large concentration of fat makes
it vulnerable to destructive free radicals. To protect brain cells, the
body produces an amino acid called glutathione, which helps defuse the
destructive force and help salvage oxidized vitamin C so it can continue to act
as an antioxidant.
Natural chemicals called polyphenols can aid in the
protection of lipids in brain cell membranes. Rich sources of polyphenols
include red wine, green tea, and soy.
Since we're talking about the
brain, let's also discuss Depression and
