Back when I started Mark’s Daily Apple, it was a small operation of just a few people with basic goals: offer my take on health, fitness, and nutrition topics. I researched and wrote the articles, and that was pretty much it. Very straightforward.
As everything has grown larger and more complex, my responsibility has expanded. I tackle ever more complicated topics that require even more research – and have a team devoted to research. The business has grown to encompass events, supplements, apparel, services, and a growing list of books, which all comes with additional duties and oversight. And amidst all that, I’m still writing articles on a daily basis.
It’s two days away from Thanksgiving here in the United States, and that means a significant portion of my readership is scrambling to put together a Primal menu. Things are easier now with the rise of the ancestral health community and the growing preponderance of related recipe blogs, but a lot of you are still wasting precious time combing through their volumes or converting standard Thanksgiving recipes into Primal-friendly recipes. You have better things to do. You have family and friends to visit, footballs to toss (or kick, as the case may be), piles of polychromatic leaves to roll around in, and thanks to give. Even if you’re an international reader, don’t celebrate Thanksgiving or know quite what it’s all about, you still like to eat great food.
For today’s edition of Dear Mark, we’ve got a two-parter. First, I cover why our desire for carbohydrates might increase in cold weather (hint: it’s probably all the shivering our muscles do in an attempt to stave off the chill). Second, I discuss why a military man might be losing muscle mass when out in the field, despite (or, perhaps, because of) all the hard physical work he’s doing. Even if you’re not military, the answer will likely still be helpful. And after that, Carrie lends a bit of sage advice to a reader who ends up with debilitating pain in her thighs every time she does high intensity plyometrics. The answer may not be what she had hoped for, but it’s probably the right one.
Mice on a gluten-free diet developed far less spontaneous type 1 diabetes than mice on a gluten-containing diet. These differences in T1D incidence were reflected in the gut microbiome. Adding gluten into the gluten-free diet changed the microbiome and eliminated the protection against diabetes. In mice, at least, gluten appears to increase the risk of type 1 diabetes, a risk controlled by changes to the gut flora.
Nuts may have their share of omega-6 fats, but a recent study shows that their consumption is associated with a rather significant reduction in mortality. Cautionary note: do not assume that nuts confer immortality.
For years now, across multiple posts here on Mark’s Daily Apple, nighttime blue light has gotten a pretty bad rap. Although I’ve mentioned that blue light during the day is important (and natural sunlight is helpful), I haven’t focused on it, mostly homing in on the circadian-disrupting, sleep-inhibiting, melatonin-blunting effects. As a result, many of you may be entirely unaware of the potential positive, beneficial applications of blue light. Recent and not-so-recent research has confirmed that blue light can actually improve our cognitive abilities, including memory, alertness, reaction time, and executive function – at least in the short term. Oh, and it doesn’t always ruin our sleep. It might even improve it if you expose yourself at the right time.
Wait a minute – blue light is good for us? Sisson, you just got done spending the last few years telling me to excise blue light from my vicinity at night if I wanted a good night’s sleep, and now you’re saying we might actually need more blue light. What gives?
