Are Microwave Ovens Safe?

To Nuke or Not to Nuke? The verb itself suggests the unleashing of atomic destruction, but we wondered, “Is there a grain of truth behind the slang?” What’s the real story behind these boxes of convenience sitting in so many of our kitchens? Are microwaves a benign bastion of modern handiness or, as some claim, […]

Dear Mark: Vitamin K2

Dear Mark, I’ve been hearing a lot about vitamin K2 lately. Should I be taking vitamin K2 supplements or is a Primal diet sufficient? Kate Thank you, Kate, for the question. You find it in politics, fashion, entertainment, art, even cooking: the “it” figure, new notable, celebrity du jour. As odd as it is, the […]

Dear Mark: Blood Markers

Dear Mark, Could you write an article on blood “markers” (cholesterols, triglycerides, blood sugar and … C-reactive protein)??? What are they?  How can they be monitored and managed? Thanks mucho!  Can’t wait for your book. Thanks to Rob for the question today. Blood markers are essentially detectable and measurable substances in the blood. Their interpretations […]

The Dirt on Dirt

The prevailing opinion at MDA is that listening to one’s body is good policy. Natural instinct has been kind to us over the years – just as long as we listen to it. Oh, sure, some instinctual behaviors have little relevance nowadays and should be ignored (like our tendency to tribalize and shun newcomers for […]

Eating Habits and Memory Function

Diet is a powerful force as we say time and again. Most of the studies revolve around the physical aspects: inflammation, disease risk, body composition, blood markers, etc. But there’s the promise a good diet can offer other elements of health, including cognitive performance. With climbing rates of dementia and Alzheimer’s, these correlations are nothing […]

Weekend Special: Human Foie Gras

Rejoice! A new clinical study was just released linking a low-carbohydrate diet to reduced liver fat. Get this, though – the scientists actually compared the low-carb diet to a low-calorie diet and found the low-cal diet severely lacking. Their results aren’t surprising, especially to our readers. In fact, we’re almost tempted to put this in […]

Aflatoxins, or Another Reason to Shun Peanuts

We already tend to steer clear of peanuts for some obvious (to our readers) reasons: the fact that they’re legumes, rather than actual nuts; the potentially dangerous, “anti-nutrient” lectins found in them; and their prominent spot in the upper echelons of the “Most Common Food Allergens” list. But there’s another reason to steer clear of […]

Dear Mark: Sunglasses and Sunlamps

Dear Mark, We’re heading into the winter months (it’s chilly even here in Atlanta!) and the days are getting shorter. As “Lights out: sleep, sugar, survival” taught us, we’re wired to handle seasonal patterns of sunlight exposure. What are your thoughts on maintaining a tan year round? Would you be better off letting your tan […]

Your Heart is Telling You to Sleep

A study in a recent issue of the Journal of the American Medical Association suggests that sleep is an integral ingredient for heart health. For the study, researchers from the University of Chicago outfitted 495 healthy, middle-aged volunteers with actigraphs, a device worn on the wrist to measure movement and rest. Accounting for some degree […]

This exciting project is nearing completion, with a planned publication date of April, 2009. In the spirit of the holiday season, I want to give you a detailed sneak preview! The message […]

Dear Mark: Brain Pills

Dear Mark, I’ve been a faithful reader of your blog for a couple of months now since Tony Horton turned me on to it at one of his fitness camps. Anyway, the reason I am writing today is to refer you to an article about some scientists who are proposing “cognitive enhancing drugs” for healthy […]

Dear Mark: Flu Shots

Dear Mark, I’m sure you know it’s gearing up toward flu season again, and the folks at work have started pushing for flu vaccination sign-ups.  I’m always a bit wary of Big Pharm and the “common knowledge” of what’s good for us (more so than ever since I first started reading MDA), so you’ll understand […]

New Findings: The Link Between Cancer and Exercise

Lance Armstrong has always been seen as the exception, rather than the rule. Conventional wisdom told us that he succeeded in spite of his cancer; that exercise is the realm of the healthy, rather than the ill. And it is that popular image of the bedridden, languishing cancer patient so prevalent in movies, media and […]

Don’t Let “D” Stand for Deficiency

Remember how we’re always going off about the importance of getting enough vitamin D in your life? How outdoor activity – and vitamin D producing sunlight – is important for any Primal Blueprinter? It seems some recent scientific research is again making this point for us.

Dear Mark: To Tea or Not to Tea?

Dear Mark, Do the benefits of tea outweigh its negatives (caffeine, teeth staining, etc.)? Is tea a worthy substitute to a glass of water? If so, how many times a week should one drink tea? Given our big fall theme the last week or so, I thought this was an especially timely question. The truth […]

Sports Fans, Fish Eyes and Dental Hygiene

Ah, yes. Another mishmash of random yet relevant contemporary science news updates is upon us. This week’s offering includes news that engaging in sports (or even just being a fan) can improve one’s mental faculties; that though a diet rich in oily fish is supremely beneficial to your overall health, just a once-a-week fishy fix […]

Reader Response: Better Fish Choices

Thanks so much to everyone for their comments and emails on last week’s “Farmed versus Wild Salmon” post. The response, both posted and personal, was amazing. It’s what I love about doing the blog – getting you, our MDA readers, the information you want and the resources you can use. Keep those comments and suggestions […]

Salmon: Factory Farm vs. Wild

Last week I noted in my podcast with Jimmy Moore how expensive genuine wild salmon can cost. Since then, I’ve received a healthy number of emails asking for more info, tips, and the real benefits behind buying “wild.” What exactly are salmon “farms”? How does the farm setting change the nutritional content of salmon? Is […]

New Study: Exercise is Good and Lowers Obesity

In a new study out of the Archives of Internal Medicine investigators discovered that even people with extra copies of the “fat mass and obesity” genes called FTO did NOT get fatter if they were active throughout the day. In other words, a so-called genetic predisposition to obesity was effectively avoided when the owners of […]
