Dear Mark: Cruciferous Vegetables and Hypothyroidism, Sprint Frequency, Protein Sources for Orthodox Lent, and Saunas

For today’s edition of Dear Mark, I discuss the connection – if one even exists – between cruciferous vegetables (and their goitrogens) and thyroid function. A theoretical interaction exists, but should this impact your decision to eat steamed broccoli? Next, I explain why I recommend one, maybe two days of sprinting a week, in contrast […]

Dear Mark: Milk Thistle and Estrogen, Low Libido, and Pollution Mitigation

For today’s edition of Dear Mark, we’ve got a three-parter.

Dear Mark: Cold Weather Sprint Alternatives, Palm Olein, Podcast Questions, and Dark Circles

For today’s edition of Dear Mark, we’ve got a four-parter. First, I discuss some alternatives to traditional outdoor sprinting for people in cold weather. Just because you can’t go run 100 meter dashes doesn’t mean you can’t get a fantastic sprint workout. Running is unnecessary. Next, I give my take on the suitability of palm olein […]

Dear Mark: Salmon and Mercury, Fruit and Sugar, plus Seniors Gaining Muscle

For today’s edition of Dear Mark, I’ll be covering three topics. First, salmon and mercury. We’re often told to watch out for mercury in wild fish, but the story is actually more complicated than that. Learn how to tell if wild fish is safe to eat and whether wild salmon should be limited. Next, I […]

Dear Mark: Garcinia Cambogia, Ultra Pasteurization, Getting Better All the Time, and How Much Walking is Enough

For today’s edition of Dear Mark, I’ve got a four-parter for you. First, I address the popular new supplement being touted as a powerful fat-burner: garcinia cambogia. Does it measure up to the hype? Next, I discuss the effects of ultra pasteurization on the proteins, vitamins, and health effects of milk. Is ultra pasteurization a […]

For today’s Dear Mark, we’ve got a series of questions and answers related to the successful realization of your New Year’s resolutions. No matter what you’ve actually resolved to try to do, you’ll probably find something of interest in today’s post. First, I cover the eternal question everyone ponders when attempting a lifestyle overhaul: cold […]

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 […]
