The Fat Burning Brain: What Are the Cognitive Effects of Ketosis?

Although mainstream sources still mistake “the brain needs glucose” for “the brain can only run on glucose,” regular MDA readers know the truth: given sufficient adaptation, the brain can derive up to 75% of its fuel from ketone bodies, which the liver constructs using fatty acids. If we could only use glucose, we wouldn’t make it […]

Top 8 Changes Coming to Nutrition Labels

After years of committees, debates, panels, “consensus-building” retreats, and literature reviews, the FDA has finalized the new nutrition label guidelines. Packaged food companies have two years to incorporate the new labels. At that point, anything in a package that humans eat must have labels that reflect these changes. You’re probably skeptical. I was. The FDA doesn’t have […]

8 Primal Rules for Building Better Bones

Strip away the skin, fascia, muscles, organs, blood vessels of a human and you’re left with the bones: the foundation providing passive structural support. Many people accept that we can affect and even control the health of the rest of our tissues. Muscles? Just lift. Cardiovascular system? Do some cardio and lose weight. Teeth? Stop […]

Why Are Some Wines More Primal-Approved Than Others?

Wine is one of humankind’s oldest and most favorite beverages not for the health benefits, or the antioxidants, or the resveratrol, but because it enhances life. Poets, authors, artists, philosophers, and laypeople across the ages will tell you that wine makes food taste better, promotes richer conversation, unfetters creative expression (a single glass can really […]

Can Exposure to Non-Primal Foods Actually Help?

Are we shortchanging ourselves by complete elimination of potentially allergenic or sensitizing foods like wheat, peanuts, or dairy? Do we become even more sensitive to “bad” foods by avoiding them entirely? This question stems from two things I recently encountered. The first was a recent rewatcing of The Princess Bride. The second was the recent peanut allergy […]

Dear Mark: Red Blood Cell Fatty Acid Content and Obese Paleo Figurines

For today’s edition of Dear Mark, I’m answering a pair questions that, well, question some of the fundamental principles of Primal living and eating. First up concerns a study seeming to show that linoleic acid (from seed oils) is a healthier, less inflammatory choice than olive oil or fish oil. Could it be true? Find out […]

Should You Be Getting More B Vitamins?

When it comes to obtaining sufficient amounts of certain micronutrients, you’re hyper vigilant. Magnesium? You’re eating spinach, throwing back magnesium glycinate, and adding Trace Mineral drops to your water. Iodine? You’re making dulse “bacon.” To bask in the holy triumvirate of vitamin K2, vitamin D3, and vitamin A, you’re willing to eat fermented cod liver […]

Top 14 Ways to Increase Your Metabolism

On a literal level, your metabolic rate describes how much energy you expend to conduct daily physiological functions. This has many practical ramifications, however, because your metabolic rate also influences how you feel, how many calories you burn, how many calories you can eat without gaining weight, your libido, your fertility, your cold tolerance, how much […]

17 Primal Tips for Vegans and Vegetarians

We all know vegetarians and vegans. And while we have our differences, they are our friends, our family, our partners, our spouses, even our children. We all have people in our lives who avoid meat and/or animal products in general for multiple reasons—health, ethics, the environment, squeamishness, animal welfare—but we care about them. We also […]

Grass-fed Vs. Conventional: When Does It Matter Most?

By now, you’re convinced of the general overall superiority of grass-fed, pasture-raised meat. If you come at it from the nutrition angle, grass-fed wins across the board. If you’re more concerned with the ethics of animal husbandry, grass-fed animals live overall better lives than animals in concentrated feedlots. If you worry about the use of […]

Dear Mark: Meat and Yogurt for Babies

For today’s edition of Dear Mark, I’m answering one question. It comes from Kristen, a new mother to a nine month-old who’s grown so passionate about baby nutrition that she’s decided to start a fresh food business for infants and toddlers. She’s a recent reader of the blog, though, and as such needs a little […]

Should You Reduce Your Iron Intake?

Iron has an unequivocally positive reputation among the general public. After all, pregnant women use it to construct tiny humans, tiny humans use it to become slightly larger, more functional humans, and our cells require it to grow. And in many developing countries, iron deficiency is a real issue. Too little iron can have disastrous […]

Dear Mark: Bone Broth Edition

With bone broth bars popping up in cities, broth-based cookbooks appearing on Amazon, and grass-fed bone broth now available for order online, hot bone water is experiencing a renaissance. And not just among Primal devotees. Dr. Oz is recommending it as a coffee replacement and Kobe Bryant uses it to support his aging body. The renewed popularity has brought […]

6 Hidden Superfoods You Probably Already Have in Your Pantry

I generally don’t subscribe to the idea of superfoods. While I’ll try your obscure Amazonian berry that spent a fortnight fermenting in a capybara’s colon, I won’t join your pyramid scheme to help sell it. I may very well add a teaspoon of gelatinized maca root to my smoothie, but I won’t claim it’s responsible […]

Dear Mark: Healing Broken Bones, and Blended Soups

For today’s edition of Dear Mark, I’m answer two questions. First, is there a way to speed up the healing process after a broken bone? What nutrients should we make sure to consume? Are there supplements we can take, foods we can eat, lifestyle modifications we can make? The next question comes from a reader […]

Dear Mark: Lead in Crock Pots, Norovirus in Smoked Oysters, and Creatine and Carbs

For today’s edition of Dear Mark, I’m answering three questions from readers. First, what’s the deal with lead in crock pots? Some say lead leaches into the food when we cook with crock pots, while others aren’t so sure. And if the leaching of lead from crock pot ceramics into our food is, indeed, a […]

Is Conventional Wisdom About GMO Safety Correct?

Conventional wisdom demands skepticism. Whether it’s the official stance on high-fat diets (“they’ll give you heart disease, don’t work, or do work but not for long!”), exercise (“you must jog at a moderate pace for an hour a day, four days a week!”), organic food (“it’s nutritionally identical to conventionally-grown food!”), or sun exposure (“you must always […]

Dear Mark: Fasting Issues, Pullup Neck Pain, and Red Palm Oil

For today’s edition of Dear Mark, I’m answering three questions. The first one comes from Neda, who’s experiencing some issues that may be related to her fasting schedule. How should she modify her fasting? Or should she eliminate it altogether? The second question concerns a common issue: neck pain during pullups. Why does it happen […]

Is All Yogurt Created Equal?

To answer the title, kind of. The same basic principle of yogurt-making applies to all yogurts: the inoculation of milk with specific strains of yogurt bacteria followed by incubation at a temperature warm enough to encourage growth and proliferation. Yogurt is milk transformed into a creamy, tangy, more nutritious product. All yogurt is initially created equal, but […]

What’s So Healthy About Avocado Oil?

It doesn’t take much digging to figure out that most of the oils we eat in this country are fantastically poor choices. There’s the heavy processing to consider as well as the GMO sourcing, the rancidity, and dramatic omega fatty acid imbalance to name a few unsavory points. Sure, we make different choices in our […]
