BEST BRAIN FOOD YOU NEED BEFORE READING FOR SCHOLARSHIP EXAMS

I cannot overestimate in this article the importance of you having a healthy, correctly functioning brain.

Your brain is the master control bio-computer that you have.

It generates every thought and mood. It controls your movements, regulates your breathing, heart heat and temperature, it controls speech, reading and writing.

Your immune system is controlled by your brain. Despite all these the brain is the most poorly nourished organ of the body.

The brain of man weighs about three pounds which represent about 2% of the body mass, yet it uses 20% of the body’s total energy supply. The estimated billion plus neurons in your brain has a voracious appetite for fuel. The fuel includes sugar, oxygen, vitamins and minerals and fatty acids. You must satisfy your brain of all these everyday of your life if the brain is to function efficiently. All these nutrients must be delivered constantly to the brain by your bloodstream. Unconsciousness results if blood flow is interrupted for even 15 or 20 second. The brain is severely demanded or worst still dies if it is deprived of blood and oxygen more than 5 minutes. Your brain needs a lot of energy in the form of the body’s standard energy chemical, ATP (adenosine triphosphate). ATP is a substance the body uses to store chemical energy, just as a car battery stores electrical energy.

When a cell needs energy, it breaks down the ATP molecules to release its stored energy. This is used in many ways
To generate neurotransmiters,
To conduct electrical impulse,
To transport protein to the cells,
To extend new nerve connections to other brain cells, to rebuild worn out cell membranes.

To achieve all these, the brain must produce the energy locally, inside the bullions of neurons that use the energy.

HOW IT MAKES THE ENERGY:
The power plant of the cells are the hundreds of little structures called mitochondrian that we see inside each neuron. Fuel is burned in these power plants to produce the crucial ATP energy which the brain depends for its life.

The brain can only utilize sugar though other parts of the body can use fat or sugar as their fuel. This creates a problem for the brain since this sugar cannot be stored in its cells; the brain is dependent on a constant delivery of this fuel by the blood thatcirculates throughout its blood vessels.

The brain consumes about 50% of all the sugar (glucose) in the body. The blood stream must be relatively free of insulin if the brain will be able to claim this disappropriate amount of sugar. When there is little or no insulin in the blood stream, the other organs of the body ignores the sugar and rely on the fat as their energy fuel, thereby leaving most of the blood sugar for the brain.

THE EFFECT
Our modern day food is characterized by the following:
It Contain High sugar
It Contain Low-fibre.
Is Processed

All these tend to stimulate frequent insulin release into the blood stream. There is surprisingly little sugar in the blood of a healthy non- diabetic person; in fact, the entire blood circulation of the human body normally contains less than one teaspoonful of sugar.

When you consume high-sugar soft, drink, candy, doughnuts, dried fruits, etc you may be flooding your body with ten to twenty teaspoons of rapidly absorbed sugar. A portion of our brain called the hypothalamus is constantly monitoring blood sugar. It tends to send a message to the pancreas to squirt some insulin into the blood in order to lower the level to normal. This is essential, for excessive blood sugar levels can cause many problems- even death.

The insulin in turn signals all body cells to grab sugar from the blood. All other organs like heart, lungs etc thereby compete with the brain for blood sugar. So, ironically the way to get adequate sugar fuel to the brain is simply to avoid simple sugar foods such as soft drinks, candy sweet pastries, jellies and jams in the diet, because these are the foods that most powerfully trigger the release of insulin in your body.
