Feature Article: Nutrition
Food when converted into glucose is the source of brain energy.
Glucose cannot be stored. As blood sugar it requires constant
renewal. If glucose is not renewed the body and the mind shows
evidence of fatigue, mental confusion, faintness, headache, memory
loss, dizziness, vision problem, cold hands and feet.
Reduced blood pressure, tension, depression and hunger are
all symptoms of hypoglycemia. This can be caused by the lack of
a balanced meal within the past five hours. Ten hours without
food will severely affect decision-making ability, alertness,
coordination, and perception. Skipping breakfast causes fasting
hypoglycemia. All hypoglycemia types can be aggravated by other
physiological factors.
Altitude can incapacitate a pilot through dehydration. Increase
your fluid intake prior to and during flight. What you eat is
just as important as just eating. Reactive hypoglycemia can cause
lack of consciousness. This is a reaction to the doughnut/candy
bar meal. The student pilot who does not eat because of possible
airsickness is endangering himself if flying solo. High sugar
meals cause the pancreas to create excess insulin. Insulin allows
the body to use sugar. Too much insulin and deplete sugar to such
a low level as to incapacitate the body and mind. Adding caffeine,
alcohol and nicotine acerbates the problem. Flying should be preceded
by a balanced meal. Neuronutriments are the vitamins and minerals
that the body can change into neurotransmitters. Trace minerals
such as potassium, zinc, iron, and chromium are essential to control
the body’s sugar burning process. The more balanced our meals
the better will be our mental functioning and memory.
