I have read this article and it is very important for me to share to all my friends and all buddies...especially for student, it is very useful for u....
The food we eat affects uor body, and that includes our brain. Good nutrition is needed for the brain to receive nourishment. Only then will the brain receive a regular healthy supply of blood and oxygen, and be in prime condition.
What is good for our brain?
WATER: Water is a main component in the human body and makes up more than two-thirds of the body. It facilitates communication within the brain and the central nervous system because it is an efficient conductor of electrical and chemical energy. Drinking an adequate amount of water each day will keep you alert and is supposed to help you improve your memory. It is best to drink water at room temperature, in small doses, throughout the day.
FISH: Fish provides us with the ingredients which help in the development of human intelligence and genius. The flesh and oils from cold-water fish are good for the brain. Avoid shellfish, however. Some cold-water fish include: salmon, tuna, mackerel, anchovy, lake trout, bluefish, and herring.
What food is not good for our brain?
SHELLFISH: may contain oceanic toxins and pollutants, and it is best to keep clear of them.
MEAT: can take quite some time to digest. Pork and beef take the longest time to digest, and turkey inherently contains a chemical which makes you feel sleepy. If you are to stay alert after a meal, with your concentration at peak level, it is best not to eat them. Take chicken instead. Meat can also contain synthetic chemicals. Wild meat and game are free from synthetic chemicals, and can be very good.
PROCESSED SUGAR: and products made from it are harmful for a person’s memory. The immune system is weakened, as the ability to resist and fight infection is greatly reduced. When you take processed sugar, insulin in the blood is churned up, the pancreas goes wild, and a sugar rush occurs. This results in "high highs" followed by a "crash" which leads to depression. Your ability to focus and your memory will suffer. Sugar in natural form is either labeled molasses or muscovado, and it can be found naturally in fruits.
COFFEE AND TEA: If you drink coffee to keep awake for an examination, you may have to think twice. Drinking several cups of coffee and tea a day will have a diuretic effect where essential minerals like potassium, magnesium and calcium are flushed out of one’s system. Caffeine, the stimulant that keeps you awake, is known to raise blood pressure, and can lead to high blood pressure, heart attack or stroke. Consistently high blood pressure can do great harm to the brain, heart and kidneys.
SOFT DRINKS: These drinks contain a lot of processed sugar, and a regular high intake can lead to hypoglycemia or Attention Deficit Disorder. The latter is an affliction that has struck numerous children who are inherently bright, but unable to maintain concentration in the classroom. Water and fresh fruit or vegetable drinks are desirable alternatives to soft drinks.
ALCOHOL: Unless taken in moderation, it ravages the brain cells and impedes the immune system. When the immune system is not allowed to function properly, a person’s ability to recall information can be adversely affected.
