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 […]

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 […]

Dear Mark: Rancid Fat, Store-Bought Mayo and Rice Bran Oil

It’s been a while since I published a Dear Mark post and it’s been a fairly anemic news week, so I thought I’d address a trio of (related) reader questions. If you’ve ever wondered what it means for a fat to be rancid (both for the fat and your body if you consume it), whether […]

Dear Mark: Seasonal Affective Disorder and Light Box Therapy

With holiday fun come and gone, it’s the time of year when we all truly settle into winter. Spring is a long way off at this point. The cold and darkness aren’t going anywhere any time soon. Most people find their way through the season with a mixture of enjoyment and impatience (and maybe a […]

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 […]

Dear Mark: Sun Exposure and Glass

These days many of us go to work in the dark and leave greeted by the same. Those lucky enough to have windows next to their desks or work stations might think, “Hey, at least I get some sun exposure during the day.” But how does sun exposure through glass compare with direct sunlight? One […]

Dear Mark: The Origin of Human Infectious Disease

Just a light and playful topic for your Tuesday morning…. What can I say? Since my posts on human longevity, I’ve had germs on the mind. Aaron Blaisdell’s response to Part 2, however, truly inspired today’s topic: Excellent post! I wonder how much infection afflicted human populations prior to the adoption of animal domestication. Jared […]

Dear Mark: Primal Advice for High Schoolers

It’s a question that frequently comes my way. Teenagers, who have found MDA and jump on board with the PB, have their brand of difficulties going Primal: skeptical – if not disapproving – parents, decidedly un-Primal school lunches and social outings, team fast food stops, etc. How does a high schooler go Primal when his/her […]

Dear Mark: Primal Wedding Menu

A couple weeks ago, I received an interesting request from a reader: Hi Mark – first, I know you’ve got a gob of emails beckoning you….I just hope that you can get back to me at some point I love reading your blog, so much so that I’ve decided I would like to pursue a […]

Dear Mark: Acupuncture

With all the recent focus on alternative and complementary therapies, the number of people using acupuncture and the variety of conditions it’s used for are quickly expanding in the U.S. A good number of MDA readers use it, I know, and quite a few have asked about it over the years. A few I know […]

Dear Mark: Nursing and the Primal Eating Plan

I’ve received the question numerous times, and last month several readers raised the issue in my “Ask Me Anything” post. For all the innumerable benefits of the Primal Blueprint diet, there are a handful of situations that oblige a few modest accommodations. In the past I’ve suggested Primally-minded adaptations for endurance athletes. Today I’ll take […]

Dear Mark: Curbing Compulsive Eating

Living the Primal Blueprint is all about taking ownership of your health and everyday choices. A lot of readers tell me that once they had made the commitment and jumped in with both feet they enjoyed a sense of control and peace with both their health and physical selves that they’d missed for years. For […]

Dear Mark: Rapid Fire Answers to Your Most Pressing Primal Questions

Last week I said “ask me anything” and you came back with nearly 300 comments! From funky-smelling Vibrams to Primal supplementation to training recovery, it was a mixed bag. Below you’ll find rapid fire responses to more than a dozen of them. Check back later this week when I’ll be providing more solutions to your […]

Dear Mark: The Low Carb Flu

Conquering carbs offers a whole constellation of rewards, not the least of which is a steady, brisk energy unlike most people have known before (well, maybe since the whirling age of 10 or so…). People tell me constantly that they can finally make it through the day without being down for the count every midafternoon. […]

Dear Mark: Seasonal Allergies

By numerous accounts, this spring has been the most brutal in years for seasonal allergy sufferers. (Do I see some nodding heads out there?) As much as everyone looks forward to spring, some folks grit their teeth for several weeks or live on a steady dose of allergy pills. I always get questions this time […]

Dear Mark: Sleep and Oxidative Stress

Dear Mark, The time change pretty hit me hard this year. I’ve noticed that as I age I value my sleep more and more. When I was in my 20s and 30s I use to be able to get by on about 6 hours of sleep each night. Now if I don’t get at least […]

Dear Mark: Nuts and Omega-6s

Nuts have gotten a surprising amount of flack as of late. Many nuts have a fairly high PUFA content, and most of that PUFA is Omega-6, which is the bad one. It’s easily oxidized, highly unstable for cooking, usually rancid on the shelf, and, thanks to government farm subsidies and public hysteria over animal fat, […]

Dear Mark: Embodied Cognition

The following reader email brought to mind a NY Times article I read a few weeks ago. The article discusses a fairly new field of research that is uncovering the surprisingly fundamental and intricate ways our bodies influence our thinking and vice-versa. We’ve discussed the mind-body connection in the past, but embodied cognition puts the […]

Dear Mark: Omega-3s and Fish Allergies

By now we all know the benefits of fish oil and its omega-3s: lower risk of heart disease, stroke and cancer, less systemic inflammation, lower risk for depression, better skin, and so on. Although fish and fish oil supplements are the best sources for these omega-3 benefits, there are nonetheless scenarios that rule out these […]
