HoustonChronicle.com - CDC: Dangers of being overweight overstated

CHICAGO — Being overweight is nowhere near as big a killer as the government thought, ranking No. 7 instead of No. 2 among the nation's leading preventable causes of death, according to a startling new calculation from the CDC.

The Centers for Disease Control and Prevention estimated today that packing on too many pounds accounts for 25,814 deaths a year in the United States. As recently as January, the CDC came up with an estimate 14 times higher: 365,000 deaths.

The new analysis found that obesity — being extremely overweight — is indisputably lethal. But like several recent smaller studies, it found that people who are modestly overweight actually have a lower risk of death than those of normal weight.

Biostatistician Mary Grace Kovar, a consultant for the University of Chicago's National Opinion Research Center in Washington, said "normal" may be set too low for today's population. Also, Americans classified as overweight are eating better, exercising more and managing their blood pressure better than they used to, she said.
[...]

Last year, the CDC issued a study that said being overweight causes 400,000 deaths a year and would soon overtake tobacco as the top U.S. killer. After scientists inside and outside the agency questioned the figure, the CDC admitted making a calculation error and lowered its estimate three months ago to 365,000.

CDC Director Dr. Julie Gerberding said because of the uncertainty in calculating the health effects of being overweight, the CDC is not going to use the brand-new figure of 25,814 in its public awareness campaigns and is not going to scale back its fight against obesity."

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.
