The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
Today’s guest post is served by a good friend of Mark’s Daily Apple, Dr. Sarah Ballantyne, PhD, or as you might know her—The Paleo Mom.
Regulating blood sugar levels is a key feature of any health-promoting diet [15, 20] . High blood sugar levels after eating are a major stimulator of reactive oxygen species (ROS), which are chemically reactive molecules that have important roles in cell signaling (the complex communication between and within cells) and in homeostasis (maintenance of a stable environment inside and outside the cell). But ROS are also potent signals for inflammation and stimulate the production of proinflammatory cytokines (chemical messengers), and also injure cells and tissue. As a result, chronic high blood sugar levels can cause serious damage throughout the body, including to blood vessels and vital organs. This is why diabetes (chronical hyperglycemia) is associated with higher risk of stroke, cardiovascular disease, vision problems, kidney disease, and nerve damage.
By next year, Americans are expected to spend nearly 11 billion dollars on skin care annually. By some estimates anyway, the biggest share of this market goes to “anti-aging” products. Anti-aging… As I noted in an offhand way a few years back, there’s a certain enjoyment in looking good naked (or just looking good), and there’s nothing wrong with that. Looking “good” is largely a reflection of optimum inner health—nothing un-Primal about that. Great health is what we’re all here for. The “extra” rewards that come with it aren’t anything to shake a stick at—or to be sheepish about.
But the health ambition isn’t really what’s behind the statistics above. At their best, anti-aging products boost the body’s natural processes (or at least don’t undermine them with toxins). At their worst, these products promise a way to cheat effort as well as time. While taking care of your skin is part of basic hygiene, too often the claims have more in common with a hat trick than genuine wellness. But which is which?
For today’s edition of Dear Mark, I’m answering four questions. First, I give a few options for recreating, or at least approximating the emulsification power of the mighty egg yolk for a reader who’s allergic (and give a quick preview of an upcoming Primal Kitchen product). Next, I explain why people with sleep apnea often grind their teeth, and mention an nutritional factor that might also cause grinding. Third, can you ferment frozen vegetables? Should you ferment frozen vegetables? And fourth, is fermented food safe while breastfeeding?
There’s a saying that people who snore always fall asleep first. My days of overnight sports chaperoning and group camping trips have frequently confirmed that notion. Most people would say that snoring is less a problem for the snorer than anyone lying awake in the vicinity, and on those specific nights in memory I probably thought as much. But the health researcher in me knows there’s more to the story.
We know sleep apnea is a big deal. No one wants that. But regular, run-of-the-mill snoring? Is it really an issue? Everyone has someone in their family who does it. It’s often a running joke, in fact. Some estimates suggest more than half of us snore (although that might be an exaggeration, given that the estimated range is so extensive). How concerned should we really be? And what is there to do about it anyway?
For today’s edition of Dear Mark, I’m answering two questions. First, what’s the deal with salt room therapy? Are there actual benefits, particularly for dermatological and respiratory conditions, to sitting inside a room as aerosolized salt wafts over you? Second, what can a reader do who absolutely can’t get to sleep after training at night? Postworkout insomnia is a real drag, and it will impede your gains, so this is an important topic. Luckily, there are a few things to try.
One major downside to having these big prominent heads stuffed with consciousness-spawning brain matter is that they sometimes ache. Nobody likes a headache. You can find fetishists who enjoy pinching, slapping, biting, burning and any matter of objectively painful stimuli. But there aren’t “headache fetishists.” No one’s chugging a 32 ounce Slurpee in search of brain freeze, or getting drunk for the hangover.
The difficult thing about headaches is figuring out why they’re occurring. Pain in other areas is different. You can look at your hand if it’s hurting and figure out why. You can see the cut on your knee and know what’s going on. But you are your head, and the headache is inside. Your consciousness sits behind your eyes observing reality and directing your role in it. It’s all a big mystery. Or so it feels.
