Best Brain Nutrients – What to Eat
The right nutrients for you and your children’s brain are important. The foods you eat have a direct effect on your brain. Some foods improve your ability to concentrate. Others aid memory and facilitate the ability to solve problems. Still other generate hormones that stabilize mood and enhance concentration.
These Are the Best Brain Nutrients and the Foods That Contain Them . . .
CHOLINE: Choline is related to the B vitamins. It is converted in the brain into acetylcholine, a neurotransmitter linked to memory and cognitive function. You should make every effort to get adequate choline as you get older because the level of the enzyme needed to produce it, N acetyltransferase, declines as we age. People with Alzheimer’s disease have been found to have significantly reduced levels of acetylcholine. Adequate dietary amounts are essential for normal brain function and may play a role in preserving brain function in people with Alzheimer’s and other neurological diseases.
What to Eat: One or more servings daily of high-choline foods egg yolks, dairy,
soy, beef, liver, wheat germ, oatmeal, brown rice, peanuts and rice.
Vitamin B12 is used to produce a component of nerve cells. Deficiency can cause
impaired transmission of nerve signals as well as declines in memory and other cognitive
functions. B12 inhibits activity of monoamine oxidase (MAO), an enzyme that breaks down brain
chemicals. Alzheimer’s patients given supplemental B12 have improved memory and communications skills.
What to Eat: Two to three servings weekly of B12-rich liver, red meat, eggs
or dairy. Everyone should take a daily multivitamin and mineral supplement. People
who follow a strict vegan diet (no animal foods) should also supplement B12
AMINO ACIDS: The brain is almost completely regulated by amino
acids, the building blocks of protein. Supplemental amounts may offer additional protection:
Tyrosine (involved in alertness), Phenylalanine (linked to memory) and Methionine (involved in
motivation and focus).
What to Eat: 45 grams (g) to 75 g of dietary protein daily
about three servings. Protein from animal foods, such as beef, chicken, fish and dairy, are
complete and contain all of the necessary amino acids. Vegetable proteins (with the exception of
soy) do not typically contain all of the essential amino acids. Vegetarians should eat a variety
of high-protein foods daily, such as combining nuts with legumes, to achieve the proper
FOLIC ACID: The B vitamin, folic acid, appears to affect brain
function. One study found that older adults with dementia or other mental disorders were three
times more likely than normal adults to have low levels of folic acid. Deficiencies of folic acid
have been linked with declines in memory and abstract thinking ability.
What to Eat: Along with a multivitamin, eat two servings daily of foods high in folic acid asparagus, leafy green vegetables, lentils, wheat, fortified cereals, meat and broccoli. As little as 200 mcg. of folic acid has been shown to improve mood and relieve depression and fatigue in healthy older people.
VITAMIN C: The brain and adrenal glands are the body’s main repositories of vitamin C. Because the adrenal glands produce stress-related hormones, it is suspected that vitamin C may play a role in modulating physical and emotional stress. Stress elevates levels of the hormone cortisol, which can eventually damage cells in the hippocampus, the part of the brain involved in memory. Vitamin C is a powerful antioxidant that can minimize physical stress to brain tissue caused by such factors as smoking, alcohol consumption and air pollution. Vitamin C also assists in the production of neurotransmitters and in the processing of glucose, the brain’s primary fuel. One study found that people with low blood levels of vitamin C scored lower on memory tests than those with normal levels.
What to Eat: Two daily servings of vitamin C- rich foods which include citrus fruits and juices, tomatoes, strawberries and potatoes.
COMPLEX CARBOHYDRATES: The brain depends almost
entirely on glucose derived from the breakdown of carbohydrates for energy. Glucose provides
the energy that the brain needs for concentration and other cognitive functions, and it has been
shown to enhance memory and improve performance on standardized tests.
What to Eat: Avoid sugar, Get glucose from complex carbohydrates, such as whole grain, legumes, fruits and vegetables. About half of your daily caloric intake should come from these foods. Caution: A diet high in simple sugars (from pastries, soft drinks, candy, etc.) triggers hormonal changes that cause drops in blood glucose this increases fatigue and impairs memory and concentration. Stroke
patients with excessive blood sugar suffer more nerve and brain damage than those with lower
