The Benefits of exercise for the aging brain


     
The numbers of Americans with Alzheimer's Disease is growing.  By the year 2050,  there will be an estimated 16 million people with the disease.("How Fitness Protects Aging Brain", Dr. Mercola) Sadly, if an individual develops Alzheimer's Disease, it will make treatment of other diseases more difficult.  What are some things that can be done to prevent the onset of this disease?

Three Requirements for a healthy brain
The onset of many diseases in aging is as a result of years of poor diet and lifestyle, rather than solely being isolated to the aging process. Aging, coupled with poor diet and nutrition, poor exercise habits and exposure to environmental toxins and stress take their toll on the body.

But, there are three things that play a powerful role in maintaining sharp mental function, even in the aging brain:

  1. Regular exercise.
  2. Foods/diet.
  3. Managing stress.
The importance of staying active physically by engaging in exercise programs of walking, aerobic and strengthening exercises can't be underscored enough.  This is important in addition to mental exercises such as learning a new language, traveling, playing mentally stimulating games and puzzles. To emphasize this point, study results at the University of Edinburgh (" How Fitness Protects Aging Brain") demonstrate that people aged 70 and over were monitored via daily logs of their physical, mental and social habits.  Three years later their brains were imaged for shrinkage and damage to the white matter.  People who engaged in the most physical exercise showed the least amount of brain shrinkage. The hippocampus area of the brain (this is the brain area related to memory, showed an increase in volume).

Exercise and Stress Hormones

Stress plays its part in damage that accumulates in cognitive decline.  But, exercise can help:

  • Create new brain cells
  • Helps the brain cells to join the existing neural network.
  • Lifts the mood by boosting the production of neurotransmitters such as serotonin, dopamine and norephinephrine.
  • Increases insulin sensitivity.

Noteworthy is the fact that exercises doesn't have to be exhausting, just three to five hours per week has shown to extend its protective effects.

Diet and Cognitive Function

What we eat is of utmost importance.  Cut down on carbs and limit protein consumption to one gram/kilogram of lean body mass. Replace these with healthy fat such as butter, nuts, avocados and coconut oil. Antioxidants are also very important so make sure to consume five or more helpings of vegetables and fruits of different colors and plenty of water to help flush out toxins and keep everything well lubricated. Add in omega 3s from healthy fish such as salmon.

Supplement to battle Alzheimer's

Current research demonstrates that a diet low in vitamin can contribute to the development of Alzheimer's and mental decline.  Vitamin D is essential in fighting inflammation and probably best to have your PMD do a blood test to see where your vitamin D level is, and then follow his instructions for supplementation. Make sure to get out in the sun, this helps build levels of vitamin D. Follow your doctor's instructions regarding protection from the sun. (This can also block absorption).

Limit the intake of fructose to less than 25 grams/day. (The metabolizing of fructose over burdens the liver which takes it away from performing other important jobs like  making cholesterol).

Get adequate amounts of Vitamins B-12 and folate; both are important in the central nervous system for neuron formation and neurotransmitter formation.

Avoiding health problems that can steal your memory

Drawing of the human brain, from the publicati...Image via Wikipedia
I am constantly scouring the net for great information about natural topics.  I just found something in "O" Magazine that is a real eye opener on memory stealers.  And, how many of us couldn't stand an improvement in the memory?  I found that so many of the little stressors in our everyday lives add up to a large impact on the mind and memory.

The article covered five areas that impact mental health. I'd like to share some of the information right here.

Chronic Stress

Prolonged exposure to the fight or flight hormone, cortisol, can actually kill neurons by exciting them to death.  Hmm, does this sound like a day in your life?

How do you cope?  Well, the article suggests that people with the largest social networks had the slowest rate of memory decline.  Family and friends can mute the intensity of stress-and the brain's chemical response.

Cholesterol

If plaque gets lodged inside one of the tiny blood vessels in the brain, it can cause a "silent" stroke.  The harm this can do to the brain tissue could slow the speed at which you absorb new information.

Attacking the problem.  Well, in addition to eating a healthy diet and getting plenty of exercise, Eat about 2.4 ounces of nuts a day.  This can lower bad cholesterol by ten points.  Just make sure that you are eating raw nuts.

Sleep Apnea

The hallmark of sleep apnea is loud snoring and exhaustion upon waking. Further, the airway closes or becomes blocked for several seconds at a time.  The result is a dip in the oxygen level in the blood which can cause blood cells to starve.

The fix?  Losing 10 percent of body weight is enough to improve symptoms.  The doctor may also recommend using a CPAP machine while you sleep.  This machine delivers oxygen continuously to keep the airway open.

Hypothyroidism

An underactive thyroiod slow the metabolism which leads to faigue which causes a foggy brain.  One of the symptoms of this disorder, affecting 17 per cent of women sixty and over, is difficulty committing new information to long-term memory.

A common cause of the problem is insufficient levels of iodine, which the body needs in order to produce thyroid hormones, to seek out lots of iodine rich foods such as seafood and dairy products.

Brain rich foods high in B12, antioxidants and EFA

Bananas
tomatoes
Kale
Blueberries
Swiss cheese
Chocolate
Salmon
Brussels sprouts
Apples
Olive oil
Coffee beans
Oranges
