This odes to the banana is unattributed and sent to me via email. I can't vouch for all the scientific facts but my feeling is that they are probably true and can be verified. Enjoy a banana everyday!

Bananas Contain three natural sugars - sucrose,
fructose and glucose combined with fiber, a banana
gives an instant, sustained and substantial boost of
energy. Research has proven that just two bananas
provide enough energy for a strenuous 90-minute
workout. No wonder the banana is the number one
fruit with the world’s leading athletes. But energy
isn’t the only way a banana can help us keep fit. It
can also help overcome or prevent a substantial
number of illnesses and conditions, making it a must
to add to our daily diet.

Depression:
According to a recent survey undertaken by MIND
amongst people suffering from depression, many felt
much better after eating a banana. This is because
bananas contain tryptophan, a type of protein that
the body converts into serotonin, known to make you
relax, improve your mood and generally make you feel
better.

PMS:
Forget the pills—eat a banana. The vitamin B6 it
contains regulates blood glucose levels, which can
affect your mood.

Anemia:
High in iron, bananas can stimulate the production
of hemoglobin in the blood and so helps in cases of
anemia.

Blood Pressure:
This unique tropical fruit is extremely high in
potassium yet low in salt, making it the perfect way
to beat blood pressure. So much so, the US Food and
Drug Administration has just allowed the banana
industry to make official claims for the fruit’s
ability to reduce the risk of blood pressure and
stroke.

Brain Power:
200 students at a Twickenham (Middlesex England)
school were helped through their exams this year by
eating bananas at breakfast, break, and lunch in a
bid to boost their brain power. Research has shown
that the potassium-packed fruit can assist learning
by making pupils more alert.

Constipation:
High in fiber, including bananas in the diet can
help restore normal bowel action, helping to
overcome the problem without resorting to laxatives.

Hangovers:
One of the quickest ways of curing a hangover is to
make a banana milkshake, sweetened with honey. The
banana calms the stomach and, with the help of the
honey, builds up depleted blood sugar levels, while
the milk soothes and re-hydrates your system.

Heartburn:
Bananas have a natural antacid effect in the body,
so if you suffer from heartburn, try eating a banana
for soothing relief.

Morning Sickness:
Snacking on bananas between meals helps to keep
blood sugar levels up and avoid morning sickness

Mosquito bites:
Before reaching for the insect bite cream, try
rubbing the affected area with the inside of a
banana skin. Many people find it amazingly
successful at reducing swelling and irritation.

Nerves:
Bananas are high in B vitamins that help calm the
nervous system.

Overweight and at work?
Studies at the Institute of Psychology in Austria
found pressure at work leads to gorging on comfort
food like chocolate and chips. Looking at 5,000
hospital patients, researchers found the most obese
were more likely to be in high-pressure jobs. The
report concluded that, to avoid panic-induced food
cravings, we need to control our blood sugar levels
by snacking on high carbohydrate foods every two
hours to keep levels steady.

Ulcers:
The banana is used as the dietary food against
intestinal disorders because of its soft texture and
smoothness. It is the only raw fruit that can be
eaten without distress in over-chronicler cases. It
also neutralizes over-acidity and reduces irritation
by coating the lining of the stomach.

Temperature control:
Many other cultures see bananas as a “cooling” fruit
that can lower both the physical and emotional
temperature of expectant mothers. In Thailand, for
example, pregnant women eat bananas to ensure their
baby is born with a cool temperature.

Seasonal Affective Disorder (SAD):
Bananas can help SAD sufferers because they contain
the natural mood enhancer tryptophan.

Smoking:
Bananas can also help people trying to give up
smoking. The B6 and B12 they contain, as well as the
potassium and magnesium found in them, help the body
recover from the effects of nicotine withdrawal.

Stress:
Potassium is a vital mineral which helps normalize
the heartbeat, sends oxygen to the brain and
regulates your body’s water balance. When we are
stressed, our metabolic rate rises, thereby reducing
our potassium levels. These can be rebalanced with
the help of a high-potassium banana snack.

Strokes:
According to research in “The New England Journal of
Medicine,” eating bananas as part of a regular diet
can cut the risk of death from strokes by as much as
40%!

So, a banana really is a natural remedy for many
ills. When you compare it to an apple, it has four
times the protein, twice the carbohydrates, three
times the phosphorus, five times the vitamin A and
iron, and twice the other vitamins and minerals. It
is also rich in potassium and is one of the best
value foods around. So maybe its time to change that
well-known phrase so that we say, “A banana a day
keeps the doctor away!”
