Dear Mark: Glutathione, Workout Nutrition, Cartilage Regeneration, Pam, and the Best of the Worst

It’s another round of rapid-fire Q&A with reader questions this week. Ever wonder about olive oil in a spray can, or which meat to choose when dining out? Do you have joint issues, or questions about workout nutrition? These readers do. Read on to learn my answers to these and other questions. And if you […]

Dear Mark: Apple Cider Vinegar, DNA Damage, Lactaid, and Miracle Noodles

I’m really liking these Monday morning rapid fire question-and-answer sessions – are you? At some point, I’ll get back to the musings, but as long as you keep sending in great questions, I’ll probably keep answering them. We’ve got four this week: vinegar and its effect on insulin levels, sugar and DNA damage, the nutritional […]

The Differences Between Grass-Fed Beef and Grain-Fed Beef

When making the transition into the Primal way of life, a lot of people get tripped up on the question of grass-fed beef. Is it necessary? (No.) Is there really that big a difference between conventional beef and grass-fed beef? (Kinda.) What does grass-fed actually mean? How do conventional cows live and what do they […]

Dear Mark: Carob, Psyllium, Chia Seeds, and Vanilla

I enjoyed answering your questions last week, so let’s do it again today. We’ve got another triad this time, including another question from Hilde. There’s going to be a lot of fiber talk, some fecal discussion, and even a few bits regarding multi-level marketing schemes. I’m also going to discuss the virulent menace that is […]

6 Sneaky Ways to Work Offal Into Your Diet

Take a look at that picture to the right. Appetizing? While I wouldn’t be surprised by numerous affirmatives from the Mark’s Daily Apple community, for most people even the sight of brains, kidneys or tongue is enough to turn their stomachs. Nutritionally, of course, we can all agree that offal is fantastic stuff. Leading the […]

Is Eating Too Much Protein Going to Harm My Kidneys?

Dear Mark, I am studying to become a nurse and am taking my first nutrition class at a local college. As one of our assignments we had to record everything we ate for an entire week. After looking at my results my teacher was dumbfounded. To make a long story short, my teacher told me […]

Smart Fuel: Macadamia Oil

What can compare to the sweet, buttery mac nut’s tender embrace? As far as nuts, seeds, and pseudo-nuts go, its fatty acid profile is unparalleled. Throw a handful into a bowl of Greek yogurt, along with blueberries, blackberries, and strawberries (or any berry, really), and you’ve got yourself a rich, masterful dessert with minimal linoleic […]

Dairy and Its Effect on Insulin Secretion (and What It Means for Your Waistline)

Insulin is an old, old hormone. Evolution has preserved its structure across hundreds of millions of years and hundreds of thousands of species. Fish, insects, reptiles, birds, and mammals all secrete insulin with fairly similar amino acid arrangements (insulin from certain species of fish has even been clinically effective in humans), so, clearly, it is […]

Monday Musings: Dairy Fat Good and Placebos Win (with a twist)

Dairy resides in a murky area for some of you guys, but I think most of us can appreciate a good slab of grass-fed butter, maybe a bit of raw cheese, and some fermented dairy, either kefir or yogurt. A select few may not. If dairy makes you feel bad, don’t use it – it’s […]

Dear Mark: Are Hybrid Fruits and Vegetables Healthy?

Dear Mark, I was wanting to know if there is any danger in eating hybrid foods. I recently tried broccolini and then discovered that it was a hybrid between broccoli and Chinese kale. Is this dangerous to eat? Is it similar to GM? I would greatly appreciate your input on this before I start eating […]

A Visual Guide to Yams and Sweet Potatoes (plus How They Fit Into a Primal Eating Plan)

Quick. What’s a suitable, Primal source of post-workout carbohydrates? If the title of this post and the picture to the right didn’t give you a hint then ask your nearest Primal enthusiast and they’ll tell you without batting an eye, “yams and sweet potatoes”. If, for whatever reason, you need some extra carbs “yams and […]

Potatoes: Part Deux

Last week, I made the case that potatoes aren’t nearly as bad as some people make them out to be. They’re carby, sure, but lean, active people who can tolerate carbs are way better off eating potatoes than grains, and even for low-carbers, a potato makes for a good, gluten-free cheat meal. Their place in […]

Is Samwise Gamgee Right About Potatoes?

Potatoes are controversial in the Primal and paleo world. They represent a bolus of dietary starch, which can wreak havoc on the insulin resistant, but they are undeniably whole, real foods that don’t require much processing beyond simple heating. Grains and legumes, on the other hand, are tiny, disparate sources of calories that need soaking, […]

How Bad is Rice, Really?

The cereal grain family prides itself on its powerful, expansive arsenal of lectins, phytates, gluten, and other antinutrients. A single seed of its patriarch, wheat, can punch holes in gut linings with ease, and cousin oat has managed to obtain official recognition as being good for the heart even as it doses you with gluten. […]

In With the New

So you’ve committed to Avoiding Poisonous Things for 30 days. You read the articles from yesterday’s post, cleaned out your pantry and fridge and are ready to get Primal. Now what? After Out With the Old comes in with the new, of course, so it’s time to do some shopping. I want you to fill […]

Learning from Moose

Life adapts when necessitated by changing conditions that impact survival. These are evolutionary pressures, with nutrition being probably the strongest. Flora bend toward the sun and plunge rooty tendrils deep into soil in search of moisture and minerals, while mobile organisms walk, run, fly, crawl, scrounge, or swim for food. Herbivores prefer to go where […]

Primal Blueprint Snack List

So you’ve ditched the bags of chips and boxes of crackers and cookies. You’ve found creative uses for all the junk food that used to make up your regular diet. And you’ve Primalized your pantry, stocking up on all the Primal essentials. With nary a can of Cheese Whiz or a bag of Funyuns in […]

Is All Butter Created Equal?

The embrace (some might say exaltation) of butter is, in some respects, what sets the Primal eating plan apart from strict paleo. It is essentially pure animal fat with only minor traces of dairy proteins and sugars remaining, and for that reason I consider it a worthwhile staple. But, to answer the question posed in […]

A Visual Guide to Sea Vegetables

About 160,000 years ago the human diet expanded to include seafood. Early humans became coastal dwellers at least that long ago, and ever since then we’ve been inextricably linked to the sea. The sea contains our most reliable source (when we aren’t dining on the brains of ruminants) of the all-important, long-chain omega-3 fatty acids. […]

Further Adventures with Leptin

I mentioned a few of the working hypotheses for avoiding leptin resistance in my posts last week, including fructose and lectin avoidance, getting adequate nightly sleep, and eating at or above maintenance levels – or at least throwing in periodic carb refeeds – but there’s even more involved in establishing a good relationship with your […]
