UNLIMITED Learning - the new learning revolution and the seven keys to unlock it.

Morgan, formerly a Professor at the Institute of Human Nutrition at Columbia University in New York, recommends a diet rich in lecithin to help improve everyone's memory, but especially that of older people. Foods rich in lecithin include peanuts, soya beans and wheat germ. He also recommends lecithin and choline chloride dietary supplements to boost the neurotransmitters that are needed to improve your memory.
  The Morgans also spell out other dietary deficiencies that impair mental performance, including a polyunsaturated fat called linoleic acid which the body itself cannot manufacture. "Fortunately," say the Morgans, "it is also extremely easy to find: one teaspoon of corn oil is enough to supply an adult with all he needs. But that teaspoon is crucial for proper brain operation. Without it, the brain cannot repair its myelin sheaths, and the result may be a loss of coordination, confusion, memory loss, paranoia, apathy, tremors and hallucinations."
  They say iron deficiency is a major cause of poor mental performance. It probably affects more people in Western society than any other single deficiency. It "decreases attention span, delays the development of understanding and reasoning powers, impairs learning and memory, and generally interferes with a child's performance in school".
  The brain also needs a constant supply of other nutrients. Among the main ones are sodium and potassium. Each of your 100 billion neurons has up to one million sodium pumps. And they're vital for transmitting all your brain's messages. Sodium and potassium supply those pumps with energy. Like glucose, potassium is found mainly in fruits and vegetables. And sodium is found in most foods.
  Put simply, reduce your sodium intake and you reduce the movement of electrical current around your brain; you reduce the amount of information the brain can receive. Reduce your potassium intake drastically and you risk anorexia, nausea, vomiting, drowsiness and stupor. All could be symptoms of your brain's vital pumps not working.

Simple tips on brain food
 
  Fortunately, nearly all fruits are rich in potassium, especially bananas, oranges, apricots, avocados, melons, nectarines and peaches. So are potatoes, tomatoes, pumpkins and artichokes.
  We'll deal with some aspects of diet in later chapters, particularly for pregnant women and children. But for now, if you want your brain to be working efficiently for all forms of learning and work:
