Going Grubby: The Primal Benefits of Dirt, Dust and Dishevelment

Clearly, cleanliness is next to godliness, as they say, in this country. The number of products devoted to the sacred rite of purging and scouring American households staggers the imagination. (Ever roamed the cleaning supply aisles at Target? It’s a trip unto itself.) Every strength, size, scent, packaging, active ingredient, and formula (Would you prefer […]

Science News Roundup

While we here at MDA like to pay close attention to our bodies and use common sense to help determine what is and isn’t healthy, actual scientific evidence forms the backbone of our philosophies. We scour breaking health and nutrition news releases to make sure our ideas are supported by science. It’s important, we think, […]

Cranberry Juice and UTIs

You’ve known for years that cranberries can help stave off urinary tract infections (UTIs), but now scientists have figured out the mechanism behind the benefit! In a study published in this month’s Colloids and Surfaces B: Biointerfaces, researchers from Worcester Polytechnic Institute in Massachusetts analyzed the Gibbs free energy of adhesion changes between bacteria and […]

Workout in a Pill?

As you probably already know, we here at MDA are all about making informed decisions that produce the best results with a minimal amount of effort. For example, what’s the point in running yourself to death when you can achieve better results with a short and intense workout session? In this sense we are all […]

Carbs: The Gift that Keeps on Giving

Earlier this week I addressed the question of ideal weight and the research that suggests people in their later years benefit from a few extra pounds. But just as I cautioned that a little goes a long way, new research shows that older men and women, particularly those who eat more carbohydrates, may have a […]

Are New Prescription Drugs Safe?

In the midst of the Primal Challenge and provocative issues like insect eating, we’ve gotten away lately from our more “salty” side, shall we say. Truth be told, we realized this week that we haven’t quite felt like ourselves. We couldn’t put our proverbial finger on it until the realization set in. It was time, […]

Eggs – It’s What’s for Breakfast

Stop the presses: A new study published online in the International Journal of Obesity suggests that eating two eggs for breakfast (and not just the whites!) is healthier than eating a bagel. As avid Mark’s Daily Apple readers, this one is easy to chalk up as a “well…duh” type of study, but the researchers note […]

Exercise Variety is Key

Boredom. Monotony. Tedium. The same day after day. Dull as tombs. Nothing new under the sun. As fun as watching paint dry. While we hope these phrases don’t apply to any part of your life, we definitely hope they don’t describe, above all things, your workout! We’re half-kidding, of course. Nonetheless, variety is definitely the […]

Calorie Restriction and Bone Loss

It can seem like a cruel contradiction: lose weight, lose bone mass. Lose a lot of weight and lose even more. (Rest assured there’s more to the story, but we continue….) A collaborative study involving researchers from the University of Kansas and the University of Missouri highlights the downside of weight loss by calorie restriction […]

Weekend Backsliding?

Researchers say Tuesdays and Wednesdays are the most productive days of the week. Monday tends to be “recovery” day from the weekend, and the rest of the week, well, we’re often coasting along waiting for the weekend to arrive, aren’t we? (Ah, the lure of the weekend: the free time, the social activities, special occasions, […]

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 […]
