A recent paper in the Journal of Bone and Mineral Research found that increased bone mineral content (BMC) and bone mineral density (BMD) in childhood are positively associated with time spent doing high-impact physical activities (PA), even for those with a genetic risk of low bone mass in adulthood (1).

A concern over BMC and BMD generally arises in those over 60 years old, when low bone mass and osteoporosis can occur. However, the time of maximal bone mineral… Continue Reading

Why your doctor only wants to see you after something has gone wrong.

Dr. Stephen Schimpff calls it the paradox of American medicine.

“We have really well-trained, well-educated providers. We are the world’s envy for biomedical research. We’ve got excellent pharmaceutical (and) biotechnology companies and diagnostics (tools). But the paradox is on the other hand we have a terribly dysfunctional health-care delivery system,” said the retired CEO of… Continue Reading

A look at the effect of moderate alcohol consumption on fitness and health.

A few years ago I stopped drinking alcohol Sunday through Thursday.

I’ve never been a heavy drinker, so it wasn’t a difficult transition. For me, two drinks is letting loose and three is really getting wild, but a few nights a week I’d have a beer or glass of wine while making dinner. Once I started CrossFit, I… Continue Reading

Point-of-view combat footage offers a dramatic look at the National Guard in Afghanistan.

“It’s jammed again. I hate this thing!”

The same words are likely spoken hourly near printers and copiers in offices all around the world.

In this case, the words were uttered by an American soldier struggling with an Mk 19 grenade launcher mounted to a combat vehicle in Afghanistan.

“Oh, fuck me!” a soldier yells as rocket-propelled… Continue Reading

Thomas Seyfried, Dr. Eugene Fine explain how cancer is affected by sugar, insulin and inflammation.

Accounts of deadly tumors date as far back as 3,000 B.C. in ancient Egypt.

Yet despite centuries of study, cancer is—after cardiovascular disease—the world’s second-leading cause of death, claiming more than 8 million lives in 2012 alone, a number that’s expected to nearly double over the next 20 years.

Prevailing theories on the origin of cancer held… Continue Reading

Dr. Eugene Fine and Thomas Seyfriend talk about the links between sugar and cancer.

This year, 1,685,210 people in the United States will get cancer; 595,690 will die from it.

It’s the second-leading cause of death after heart disease, responsible for nearly 1 in 4 deaths in the U.S., and researchers have spent lifetimes studying its countless mutations in search of a cause, pointing their fingers mostly at genetics and physical, chemical and biological carcinogens.

But mounting… Continue Reading

When a pegboard showed up in Event 12 of the 2015 Reebok CrossFit Games, a lot of people were shocked.

That’s a weird reaction by any follower of a sport in which competitors sign up to face the “unknown and unknowable,” but it’s even weirder when you consider CrossFit’s Founder and CEO wrote about pegboards back in 2002.

In the second issue of the CrossFit Journal, Greg Glassman listed and sourced all the equipment a person would need to turn a garage into a “world-class strength and conditioning facility.” The article, … Continue Reading

Theresa Couture uses CrossFit to rebuild her body after suffering a stroke.

Theresa Couture fell out of her wheelchair in her kitchen, sending the chair flying across the room. As she lay there, home alone, she knew she didn’t have the strength to drag herself to the chair and get back in it.

“That was the final straw for me,” said Couture, who has mitochondrial disease (mito), which manifests itself through dysautonomia, strokes… Continue Reading

Physicians explain what “prediabetes” is and what the diagnosis means for your health.

The word “prediabetes” makes Dr. Donna Polk’s patients pay attention.

She can tell them about their risk of a heart attack, a stroke—“they don’t care,” she said.

“But when I say ‘prediabetic,’ they say, ‘What? I don’t want to be diabetic,’” explained Polk, medical director for cardiac rehab at Brigham and Women’s Hospital, a nonprofit teaching affiliate of Harvard Medical School.

The word, she… Continue Reading

Kahn is the former chief scientific and medical officer of the American Diabetes Association. He… Continue Reading

(Corrects to clarify relationship between blood sugar and sleep.)

More and more, science is confirming what athletes report anecdotally: Avoiding sugar can dramatically improve health and performance.

The first week was hard. Really hard.

“My body told me it wanted sugar,” said Tanya Chick.

An athlete at CrossFit E-Town in Evanston, Illinois, Chick said she was addicted to Trader Joe’s freeze-dried mangoes. Chick’s mango fetish came to an end the moment she signed… Continue Reading

Bill dies in committee but supporters say anti-soda legislation is just a matter of time.

The effort to pass a recently failed bill requiring health-warning labels on sugar-sweetened beverages in California is a marathon, not a sprint, said sponsoring Sen. Bill Monning.

“While it’s obviously a disappointment that we don’t have an immediate vehicle … we won’t just lie dormant. We will use 2016 to continue to educate… Continue Reading

Marion Nestle talks about how Big Soda is under attack from communities and people who are tired of obesity, diabetes and bad science.

The ingredients in soda are simple: carbonated water, high-fructose corn syrup and sucrose, caramel color, phosphoric and citric acids, caffeine, and natural flavors. The ingredients may be simple, but their impact is profound.

Selling this flavored sugar water has turned The Coca-Cola Co., PepsiCo Inc. and Dr Pepper Snapple… Continue Reading

T.J. Murphy explains how he ditched his traditional running diet, lost weight, didn’t bonk and felt better.

On Aug. 9 The New York Times published “Coca-Cola Funds Scientists Who Shift Blame for Obesity Away from Bad Diets.” The report focused on Coca-Cola’s financial support of a group of scientists pledging to fight the obesity crisis by calling for more exercise rather than intake of fewer calories.

The article created a backlash that set… Continue Reading

Clinton Foundation sends mixed signals by partnering with Coca-Cola while claiming to work for health and wellness.

The exhibit marks “The Coca-Cola Bottle’s 100-year anniversary” and features iconic images from the last century of Coca-cola marketing, complete with the classic small-town… Continue Reading

Scientists link repeated hydration with sugar-sweetened beverages to kidney disease and early death in Central America.

It’s called La Isla de Viudas: Widows’ Island.

The name comes from the rural sugarcane-worker community of La Isla in Nicaragua, where thousands of men have died from the same epidemic over the last two decades. All perished of chronic kidney disease, referred to as “CKD,” and researchers estimate the overall death toll in Central America is at least 20,000. The… Continue Reading

Our bodies fight restrictive diets in every way possible, resulting in weight gain, not weight loss, over the long term.

Starting a new diet can be thrilling. It’s a time of hope and possibility. The process often starts with a trip to the drugstore for a notebook to write down the details of every meal. Then it’s off to the grocery store to fill the cart with strange ingredients such as chia seeds and apple-cider vinegar… Continue Reading

Researchers say traditional weight-loss guidelines obscure the effects of calories from different sources.

It’s a law of thermodynamics: A calorie in equals a calorie out. Energy is neither created nor destroyed.

In other words: Calories don’t disappear. The idea is that as long as you’re eating fewer calories than you’re expending, you shed pounds. You can do this with a diet of Twinkies and candy bars or with salmon and arugula.

But food is more than just its caloric value.
