Should We Allow Drugs in Sports?

Dear Mark, I know you used to be involved in triathlon sports administration. I see so much written about “banned substances” and “cheating” going on in the world of professional sports these days, especially with the Olympics looming. What do you make of all this? Ray Ray, my position hasn’t changed on this issue in […]

Relaxation Response

In the last few months we’ve been highlighting new research that illustrates the power of individuals to influence their genetic expression through basic lifestyle choices, whether through diet, exercise, or avoidance of pollution. The message, as always, is that we aren’t passive victims to aging or any propensities in our genetic heritage. How we live […]

Sleep More to Forget Less

A study presented this week at the Forum of European Neuroscience conference in Geneva, Switzerland suggests that a good night’s sleep can improve memory. For the study, researchers from the University of Geneva in Switzerland enlisted 32 volunteers to each learn a new skill, such as following a moving dot on a computer screen using […]

Fat-Oxidation Damage Control

Earlier this week we watched Mark make his signature salad: a veritable cornucopia of vegetable wonder (and anti-oxidant powerhouse). We’ve also heard Mark talk about his personal penchant for a good glass of red wine (another bearer of anti-oxidant goodness). It seems we primal types can’t get enough of those polyphenols, can we? And, wouldn’t […]

Unrestricted Low-Carb Diet Wins Hands Down

The New England Journal of Medicine has just come out with perhaps the most definitive comparison of low-fat, Mediterranean and low-carb diets ever, and the findings dovetail very nicely with what we’ve been discussing here recently about the merits of the Primal Blueprint. I think it also addresses some of the concerns shared about the […]

Watermelon a Natural Viagra?

A study by researchers at the Fruit and Vegetable Improvement Center at Texas A&M University suggests that watermelon may act as a natural version of the erectile dysfunction (ED) drug Viagra. The Food of Lust? While researchers have always been aware of watermelon’s high citruline content, studies had suggested that the bulk of the chemical […]

Single Serving Packs Don’t Curb Overeating

In a study to be published in the Journal of Consumer Research, researchers from the Technical University of Lisbon in Portugal suggest that single-serve packages do little to curb overeating and may actually lead consumers to eat more. To determine the impact of smaller, individually packaged food items on overall consumption, researchers in one experiment […]

Reader Response: Insulin Index

Reader Pete asked for some thoughts on the “Insulin Index,” a measurement chart similar to the glycemic index. While the glycemic index calculates the relative blood sugar rise induced by given foods, the insulin index evaluates the insulin response generated by 38 different foods. The insulin index, which first made its appearance in a 1997 […]

Turmeric: A Spice for Life

The popular Asian cooking spice, turmeric, may help prevent diabetes and help beneficially influence body composition, according to a study slated to appear in an upcoming issue of the journal Endocrinology. Previous research has suggested that turmeric and its anti-oxidative ingredient, curcumin, can help reduce inflammation, help heal wounds and relieve pain. For the most […]

Control Your Lifestyle, Control Your Genes

Results of a dramatic study highlighting (guess what) gene expression were published last week by the National Academy of Sciences, and suddenly the popular media is suddenly paying very close attention. The study, which followed 30 men with low risk, early prostate cancer, demonstrates the dramatic role of lifestyle intervention in gene expression and corresponding […]

Have You Decided to Be Healthy?

For some people, it’s a New Year’s resolution. For others, the scare of a close friend’s or relative’s illness. Maybe it’s a scary diagnosis of their own. Oftentimes, it’s a long pondered goal. Yet even when it’s more of a “spur of the moment” pledge, the decision to be healthy usually comes after good thought […]

Cold Water Therapy

You’re in the middle of a nice, hot shower, feeling your muscles relax, the day’s tension (or night’s sleepiness) melt away. As you bask in the quiet moment of repose, suddenly your body gets a startling jolt. After a second of disoriented shock, you realize something has happened to the hot water. Did someone start […]

Save a Few Bucks, Gain a Few Pounds

The stories are everywhere on news broadcasts, mornings shows, and magazines. Bulk shopping, particularly as it’s defined by stock images of Sam’s Club and Costco, is the key to the current economic crunch, the newscasters tell us. Footage clip after clip show the enormous carts filled to the brim with essentials like toilet paper, diapers, […]

The Importance of Blood Sugar Level

Think this is a post about diabetes? Nope. (Although you wouldn’t be alone in that assumption…) In this country, if you don’t have diabetes, you’re supposedly in the clear. Not so fast, we say! Research from New Zealand offers “the largest study to date of [hemoglobin] A1C levels and subsequent mortality risk” in men and […]

Some Very Intense News

A study (abstract here) published online in the American Journal of Physiology, Regulatory, Integrative & Comparative Physiology suggests that short but intense bouts of exercise can confer the same health benefits for the heart as longer, less-intense activities. For the study, researchers from McMaster University in Ontario, Canada recruited 20 healthy but untrained individuals and […]

Primal Lifestyle Good for Your Heart?

Following a primal eating plan rich in meat, vegetables, berries and nuts may reduce the risk of heart disease, according to a small study published this month in the European Journal of Clinical Nutrition. For the study, researchers at the Karolinska Institute in Sweden recruited 14 healthy volunteers to ditch their normal diet in favor […]

Plants Preserve Muscle Mass

We’ve always been dear friends, staunch allies, and devoted advocates for our edible friends in the plant kingdom. Whatever craziness descends upon our lives and our society, there’s sanity, indeed healthful respite in a bountiful, brimming, vibrant dinner plate of vegetables. And now there’s even more reason for veggie veneration. Research from Tufts University funded […]

Vitamin D and RDA for Children

It’s probably of little surprise that we take issue with some of the Recommended Daily Allowance values and how they’re often determined. Case in point: New research published in the Journal of Clinical Endocrinology and Metabolism suggests that the current children’s RDA for Vitamin D (200 IUs) does not sufficiently support the “bone growth and […]

The Power of the Placebo

A number of months ago we reported that some 45% of Chicago internists (among those who responded to a survey) said they offered placebos to their patients from time to time. The report got people around the country talking – and maybe even wondering about their own prescription history. Clearly, physicians recognize the impact of […]

Not Enough B-6?

Researchers from Tufts University have found that people may not be getting enough vitamin B-6 with the current Recommended Daily Allowance of 2 milligrams. And that goes double for certain groups. Vitamin B-6 plays an integral role in the formation of red blood cells, regulation of blood glucose, digestion of protein, and the function of […]
