Dear Mark: WiFi Effects on Health, Creatine and AGEs, and Introducing Solids

For today’s edition of Dear Mark, we’ve got a two-parter followed by a question for Carrie. First, I discuss the effects of WiFi on health. Or, rather, I explore whether the potential effects of WiFi on health are worth fretting over or whether we should focus on more actionable factors that affect health. Second, I […]

Dear Mark: Are Supplements Useless?

It’s December 2013, which means it’s time for another round of popular news articles proclaiming “supplements are useless and maybe even dangerous.” This time they’re based on a recent editorial published in the Annals of Internal Medicine entitled “Enough is Enough: Stop Wasting Money on Vitamin and Mineral Supplements” in which the authors looked at (some of) […]

Dear Mark: Peppermint Tea, Heirloom Wheat, Dips, Waking Up When It’s Dark, and Feeding an Adopted Infant

For today’s Dear Mark, we’ve got four questions. Actually, there are five because one of the questions has two parts. First, I discuss the anti-androgenic effects of peppermint tea. Beneficial for PCOS, a mixed bag for males? Next is a two-parter about heirloom wheat (is it Primal?) and failure stories (do I get email from […]

Dear Mark: Full-Fat Dairy Roundup

Last week, I wrote about how the available evidence indicates that full-fat dairy is a very healthy, nutritious source of food for people who tolerate it. The comment section exploded with questions, so I figured I’d use this week’s “Dear Mark” to answer most of them. First up is a question about dairy’s oft-reported positive […]

Dear Mark: Gummy Vitamins, Heirloom Rice, and Regular Checkups

For this week’s edition of Dear Mark, I’ve got three of your questions and three of my answers. First up, I discuss the sugar content of gummy vitamins. Is it a problem for growing kids? Next, find out my take on heirloom rice, including whether it’s worth all the work required trying to get around […]

Dear Mark: Cold Weather Carb Cravings, Muscle Loss in the Military, and Pain During Exercise

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 […]

Dear Mark: Acid Load and Type 2 Diabetes, and the Safety of Homemade Baby Food

For today’s edition of Dear Mark, we’ve got a question about dietary acid load and type 2 diabetes. A new study’s just come out suggesting that the acid load of the diet does indeed have a significantly negative impact on our health and may actually cause type 2 diabetes. The reader is understandably worried, so […]

Dear Mark: Resistant Starch, Zinc Deficiency, and Something New

For today’s edition of Dear Mark, we’ve got a three-parter. In the first section, I discuss the extremely hot (and then allowed to cool off) topic of resistant starch, explaining who might benefit from it, who might not, and where you can find further information on the subject. Second, I briefly go over how a […]

Dear Mark: Grok’s Mobility, Too Much Walking, Fertile Eggs, and the Best Shoes for Babies

Hey folks, it’s time for another edition of Dear Mark. This time around we’ve got a four-parter. First up, I discuss why Grok probably didn’t need to foam roll with boulders or consult with a proto-Kstarr sporting a prominent brow ridge. Next, walking. It’s good, it’s vital, it’s low-stress, but is it possible to walk too much? Yes (but read […]

Dear Mark: Conditioning Bare Feet for Rough Surfaces, and Residual Weight Gain After a Miscarriage

For today’s edition of Dear Mark, I answer two good questions from readers. First up, I discuss the conditioning of bare feet for the purposes of walking across a multitude of surfaces. Believe it or not, much of the conditioning happens upstairs – in the brain. Then I give a little advice to a woman […]

Dear Mark: Calorie Intake While Nursing, Tom Hanks and Type 2 Diabetes, and DHA Bad for Adults?

For today’s edition of Dear Mark, we’ve got a three question roundup. First, I hear from a nursing, weight-lifting, child-chasing mother of four who’s concerned about the amount of food she’s craving – even though she’s already at her pre-baby weight. I (hopefully) allay her concerns in my response. Next, I discuss the ridiculous nature […]

Dear Mark: Bodyweight or Barbells, Restaurant Traps, Primal Egg Coffee Stability, and Post-Exercise Insomnia

Today’s Dear Mark is a four-parter with some fantastic questions (and passable answers, I hope!). First up, I answer a reader question from the comment section of last week’s Barbell Dogma post. Second, I discuss the number one nutritional trap of restaurant foods, and it has nothing to do with grains, sugar, or carbohydrates. After […]

Dear Mark: Salmon Pouches, Ray Peat, and Our Inherent Desire for Crispy Food

Ah, it’s good to be back with a regular old Dear Mark. Today we’re discussing the nutritional value of canned salmon, and whether the canning process negates some or much of the impressive nutrient profile of fresh salmon. After that, I discuss the dietary views of Ray Peat, an increasingly popular topic in the MDA […]

Dear Mark: Your 21-Day Challenge Questions Answered

The 21-Day Challenge is simple in theory, but not always easy, especially if you are brand new to the Primal Blueprint and trying to change decades of bad habits and unhealthy lifestyle behaviors. With the first week of the Challenge behind us, a couple days ago I asked you to share any questions you may have, […]

Dear Mark: What’s the Deal with Fiber?

Last week’s guest post from Konstantin Monastyrsky, author of Fiber Menace, generated a lively, boisterous, and at times combative comment section. I use these descriptors in the best sense possible, mind you; debate is healthy and necessary, even – nay, especially – if it’s impassioned. So right off the bat, I want to thank everyone who wrote in. I […]

Dear Mark: Am I Eating Too Little Food or Too Much Iron?

For today’s edition of Dear Mark, we’ve got a two-parter. First, Mathilde wonders whether she’s eating too little food. A high-fat, nutrient-dense Primal way of eating can have the effect of maximal satiation on fewer calories, and that’s usually fine, but there are instances where too few calories can have negative health effects. I tell […]

Dear Mark: Changing Trajectories, and Magic Mineral Broth

In today’s edition of Dear Mark I field two Mark’s Daily Apple reader questions. First up, I tackle a query from a reader who’s had to make a small but significant shift to his lifestyle due to changing circumstances. What happens when what’s worked for months and years stops working? When your daily habits, your go-to […]

Dear Mark: Cable Machine Weights, Plaque Regression, Lab Grown Meat, and Swiss Ball Chairs

For today’s edition of Dear Mark, we’ve got a four-parter. First up is a question about using the cable weights at the gym to build strength. Should they be discarded by the serious trainee in favor of exclusive barbell work, or do they offer something unique and worthwhile? Next, I discuss potential strategies for the […]

12 Aug

Dear Mark: Soy-Fed Eggs, and Liver-Polluting, Body-Acifiying, Meditative State-Preventing Meat

We’ve got a two-parter for today’s edition of Dear Mark. First, I field a question from a reader who loves eggs, raises his own chickens on open pasture, and wants to know whether or not the soy he currently includes in their diets is going to affect him. Then I evade a silly question about […]

Dear Mark: Paralysis by Overanalysis, Beer, and Liquid Coconut Oil

For today’s edition of Dear Mark, we’ve got three questions to cover. First up is a question from a reader who feels paralyzed by too much health information. Whereas before the basics might have made sense to him, digging further into the literature and the blogs is only making it harder and harder to make […]
