Your Brain Can Grow Larger with Exercise

Fitness & Health with Dr. Gabe Mirkin: Your Brain Can Grow Larger with Exercise

Your Brain Can Grow Larger with Exercise

Regular exercise makes your brain larger, according to a study from the University of Illinois (Journal fo Gerontology, November 2006). With aging, your brain becomes smaller. This study showed that 60 to 79-year-old men who exercised regularly actually had their brains grow larger. Study participants who did only a stretching and toning program had their brains shrink.

If you feel you are losing your ability to reason or think clearly, or if you suffer mood disorders such as depression, ask your doctor to do blood tests for homocysteine, folic acid, pyridoxine and vitamin B12. If these tests are normal, you should get tests for thyroid function, cholesterol and other causes of arterial damage.

You can suffer from B12 deficiency even if your blood levels are normal. When you body lacks B12, your red blood cells do not mature properly and are much larger than normal, and homocysteine accumulates in your bloodstream, damaging your arteries and brain cells. Having low levels of B12 can damage every nerve in your body including your brain, to make you forgetful and impair your ability to reason and solve problems. If you are low on B12, taking folic acid supplements or eating food heavily fortified with folic acid may cost you IQ points. A study from Tufts University showed that people who have low blood levels of B12 can suffer nerve damage, and those who also had high blood levels of folic acid had far more nerve damage than those with normal levels (American Journal of Clinical Nutrition, January 2007).

Your doctor should also check for diabetes, which can damage blood vessels that supply the brain, heart and other organs. Diabetics may suffer loss of memory long before they are diagnosed as having diabetes. While we await further studies, protect your memory with a lifestyle that will help you avoid diabetes, heart attacks and strokes. Control your weight, eat a wide variety of plants, limit refined carbohydrates and get plenty of exercise

The government has decided we need more Folic Acid, so now they fortify bread with it. The only source of B12 is meat. So now vegetarians are destroying their nerves and brains with every slice of bread they eat.

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking ...

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the...

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
