Mercola cites a study of lifelong elite endurance athletes in which half showed heart muscle scarring, and a rat study finding similar damage after prolonged exercise. He notes it remains impossible to predict the threshold for any given person.

This Part of Your Mouth Accurately Reflects Your WHOLE Body's Health...
Dentist and fluoride opponent Bill Osmunson tells Mercola that the mouth reflects what is happening in the rest of the body, and that diet outweighs cleaning. He says bottle caries, from leaving a baby overnight with juice or formula, is entirely dietary and no fluoride prevents it.

Breastfed children have stronger cardiovascular system?
Among 306 five-year-olds, those exclusively breastfed for three to six months had carotid intima-media thickness 21 micrometers greater than formula-fed children. Shorter or longer breastfeeding matched formula feeding, and carotid stiffness did not differ between the groups.

Breastfed babies not bothered by pacifiers
A Cochrane review pooling two trials with 1,302 mothers highly motivated to breastfeed found that permission to use pacifiers made no significant difference in exclusive or partial breastfeeding at three and four months, whether offered from birth or later.

Spanking and why new dads might do it
A Pediatrics study following 1,746 US fathers found 7 percent had a major depressive episode in their child's first year. Depressed fathers were close to four times as likely to report spanking a 1-year-old in the past month and less than half as likely to read to their child.

QuickStats: Average Daily Intake of Kilocalories
NHANES data for 2007-2008 show men ate an average 2,504 kilocalories a day and women 1,771. Men consumed significantly more than women in all three age groups, and both men and women aged 60 and over ate less than their younger counterparts.

Low birth weight from poor maternal nutrition causes later obesity
Researchers at LA BioMed found that in animal models, low birth weight caused by poor maternal nutrition inhibits division of neural stem cells, leaving fewer of the brain signals that control food intake, which they say programs offspring to overeat.

Protect Your Kidneys by Controlling Diabetes and High Blood Pressure
Diabetes and high blood pressure are common causes of chronic kidney disease, which often advances with few symptoms until dialysis is needed. Marking World Kidney Day on March 10, the CDC urges people with either condition to get tested and control sugar and pressure.

Teen eating disorders and associated mental health issues more common than known
Kathleen Merikangas and NIMH colleagues interviewed about 10,000 teens aged 13 to 18 and found lifetime rates of 0.9 percent for bulimia, 1.6 percent for binge eating and 0.3 percent for anorexia. Most also had at least one other mental disorder tied to social impairment.

Poll suggests technology is keeping Americans from sleep
The National Sleep Foundation's 2011 poll found 63 percent of Americans report a sleep problem every night, and that light-emitting laptops and phones are widely used in the hour before bed. Harvard's Charles Czeisler says evening light suppresses melatonin and delays sleep.

Obesity linked to higher risk of breast cancer
Among 155,723 Women's Health Initiative participants, those with the highest body mass index were 35% more likely to develop triple-negative and 39% more likely to develop estrogen-receptor-positive breast cancer, while the most active women had lower risk of both.

What dangers lay in tanning beds?
The American Academy of Pediatrics wants teenagers barred from tanning salons, noting that more than a million people a day visit them and that artificial UV radiation is classed as a human carcinogen. It says a tan means DNA damage and offers no protection against later sun exposure.
Lifestyle
Online images of self inflicted injury are popular
Canadian researchers examined the 100 most-viewed YouTube self-injury videos, seen over 2 million times. Explicit imagery was common, cutting was the most frequent method, and 58 percent carried no warning. They caution the videos may normalize the behavior.

Physical activity helps fight prostate cancer
Among 2,705 men who lived at least four years after a prostate cancer diagnosis, those walking more than 90 minutes a week at a brisk pace were 46 percent less likely to die of any cause, and those with more than three hours of vigorous activity 49 percent less likely.

Does a child's health pay the price for working moms?
Melinda Sandler Morrill reports in the Journal of Health Economics that maternal employment raised the probability of overnight hospitalizations, asthma episodes and injuries among children aged 7 to 17 by nearly 200 percent. Earlier studies found only a modest adverse effect.

Baldness could be reversed and even prevented
Researchers studying gut function in mice found that blocking the stress compound CRF for five days regrew hair, an effect that held for four months, prevented loss when started early, and restored skin pigmentation. The authors suggest it might hold potential for human baldness.

Football fanatics could risk heart attacks
A Clinical Cardiology study found heart-related deaths rose 15% in men and 27% in women in the two weeks after the 1980 Super Bowl loss, with people 65 and older most at risk, while death rates ran slightly lower after the 1984 win.
