Alcohol: The Good and the Bad

What do we make of alcohol? In sufficient amounts, it’s a poison. It’s incredibly addictive. It destroys entire communities. It tears families apart and compels otherwise reasonable, upstanding individuals to commit terribly senseless acts. On the other hand, it’s a powerful social lubricant. The good stuff tastes great and can enhance the healthfulness of certain […]

9 Ways You Might Be Inadvertently Sabotaging Your Weight Loss Efforts

Whenever friends, co-workers, or loved ones complain about not being able to lose weight and turn to us for answers or advice, we can all generally rattle off a few suggestions that, if followed, usually set them on the right track. For the soda-swilling cubicle mate who keeps a recycling bin just for cans beneath […]

Dear Mark: First Trimester Frustration, Liver Dosage, and NY Times Barefoot Piece

Being pregnant is tough – or so I hear. You’re tasked with creating a child, with actually building an entire human being bit by bit from scratch. You have to carry that child, even as it grows to seven, eight, or even nine pounds or more inside your body. And all the while, your body […]

So, Is Organic a Scam?

Over the past several weeks, I’ve laid out a considerable amount of evidence showing that there indeed are substantive differences between organic produce and conventional produce. Organic is often more nutritious, with a greater concentration of phytonutrients (contrary to what the popular media has been saying). Conventional produce shows up in your kitchen with far […]

The Problems with Modern Wheat

This may seem like a redundant topic, since most of you following a Primal eating plan are already avoiding wheat. The occasional dabbing of soy sauce, maybe a bit of crusty bread at a restaurant, sure, but for the most part, you’re not munching on baguettes in parks on sunny days, wolfing down huge sandwiches, […]

Should You Worry About Genetically Modified Food?

A new study came out last month out of France. In it, researchers found that rats on diets consisting of 11%, 22%, and 33% Roundup-resistant genetically modified corn developed far more mammary tumors than control rats on non-GMO corn diets. GMO diet rats died earlier and in greater numbers. Why is this study notable amidst all […]

Fall Foods: Why Seasonal Eating Primes the Body for Fat Burning

This is a guest post from Mira and Jayson Calton of Calton Nutrition. As many of you know, I’ve written extensively on the seasonality of eating, and the fractal nature of early human existence. In this guest post, the Caltons share a few of their own insights and discoveries on seasonal eating patterns, and provide […]

Is Organic a Scam? – Nutrient Differences

Even if you can get folks to begrudgingly admit that organic foods tends to contain fewer pesticide residues than conventional (and that this might even impact a person’s health or the way a child develops), they’ll dig in their heels when it comes to the nutritional content. And why shouldn’t they? Organic isn’t really about […]

Is Organic a Scam? – Fetal and Child Development and Antibiotic Resistance

A few weeks ago in Weekend Link Love, I mentioned the great big much-ballyhooed study that appeared to show organic produce was no more healthy than conventional produce. Many people with an axe to grind championed its findings, with some proclaiming the undeniable ringing of the final death knell of organic farming. Science Based Medicine […]

Dear Mark: Ornish Strikes Again, Vitamin D from Light Boxes, and Kimchi and Cancer

Ah, it’s good to be back in the saddle again. The challenge was a lot of fun – don’t get me wrong – but ultimately both you guys and I come here for the dispensation of musings and information and writings and discussion on health, fitness, and any other number of lifestyle topics. So, let’s […]

How Common is Gluten Sensitivity?

I’ve long suspected that everyone has some degree of sensitivity to gluten, even if they’ve never been formally diagnosed and even if they don’t notice any overt symptoms after eating it. Now we have concrete evidence that non-celiac gluten sensitivity actually exists. My own story was that of a lifetime grain-eater who defended my “right” to eat […]

Is Your Olive Oil Really Olive Oil?

For thousands of years, humans have been picking, prizing, and pressing the fatty drupes found among the oblong leaves of the gnarled, twisted olive tree into rich, green-gold extra virgin olive oil. And for almost as many thousands of years, humans have been coming up with ways to fake it, to pass off cheaper, less […]

Dear Mark: Should I Increase Carb Intake for Weight Loss?

Sometimes, weight loss slows. Sometimes, what worked amazingly well before, stops working quite the same. Although this can be scary, frustrating, annoying, or all of the above when progress slows, stops, or requires new input to continue like it was is ultimately okay, because we are an adaptive species. We can change things up, shift stuff […]

Is Wheat Addictive?

Within the Primal/paleo community and elsewhere, it’s often stated offhandedly that wheat is addictive. And absolutely, wheat for many people feels like something they could never give up. I hear it all the time: “I couldn’t live without bread.” “What would I do without cereal, dinner rolls, toast, {insert your favorite grain-based food item here}.” […]

Why Did My Cholesterol Go Up After Going Primal?

While the majority of people who go Primal see their blood lipids improve, a significant minority do not in the short term. They see LDL cholesterol skyrocket, or their total cholesterol increase, and sometimes triglycerides even mysteriously elevate despite a low-carb intake. What’s going on here? Should you go on statins? Should you add grains […]

Dear Mark: Preservatives in Lard, Ace-K, Raspberry Gorging, and Veal

What would you do if someone gifted you with a 5-pound tub of lard? Jump for joy? Grab a spoon? All reasonable responses, but what if that tub of lard had a label that said “contains BHA and BHT”, two antioxidants commonly used to preserve processed food, cosmetics, and pharmaceuticals – how would you react?

How Bad is Peanut Butter, Really?

Man, you guys really love your peanut butter. I get at least one email a week from a devoted reader of the blog who just can’t shake the desire (that feels like a need) to eat peanut butter on a regular basis. They’re on board with everything else. They’ve ditched grains and vegetable oils. They’re […]

Nuts and Phytic Acid: Should You Be Concerned?

Who doesn’t like nuts? They’re crunchy, fatty, nutritious, and convenient. They travel well. Tossing them into the air and catching them with your mouth is a fun way to impress any onlookers (this effect is enhanced if you sit in a chair backward at the same time). They even turn into butter. Nuts are the […]

2 More Common Nutrient Deficiencies (and What to Do About Them)

In our rush to ditch processed, boxed, packaged, refined foods, we run the risk of missing out on several key nutrients that they come fortified with, courtesy of food producers (what would we do without them?!) who recognize that the people who live off their nutrient-free food products need some actual nutrition amidst the sugar […]

Should You Chew Your Child’s Food?

By now, you’ve probably seen the Alicia Silverstone pre-mastication video. It’s totally safe for work (maybe not for lunch, but your mileage may vary), but some viewers will find it a bit unsettling: Silverstone feeds her baby pre-chewed food directly from her mouth, just like a bird. I found it pretty fascinating and not at […]
