Dear Mark: WiFi Effects on Health, Creatine and AGEs, and Introducing Solids

3597145 LoResFor 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 answer a three-part question about creatine and advanced glycation end products. Is there an interaction between supplementary creatine and AGE formation? Are the two contraindicated? Finally, my dear wife Carrie answers a question about introducing solids to a breastfed infant.

Dear Mark: Are Supplements Useless?

vitaminsIt’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) the research on vitamin and mineral supplementation and prevention of various ailments. Understandably, I got a bunch of emails from people worried that their supplements were useless or might even be hurting them. Let’s look at one of them and see what people are saying:

Dear Mark: Peppermint Tea, Heirloom Wheat, Dips, Waking Up When It’s Dark, and Feeding an Adopted Infant

mintteaFor 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 people who haven’t had resounding success with the Primal lifestyle?). Then, I explain what your dip technique (tricep exercise, not chip consumption method) should look like in order to minimize the risk to your shoulder health. Finally, I help a reader out with a conundrum: being unable to get going in the morning because it’s so dark outside upon waking. My wife Carrie takes over from there, giving her take on a few approaches to feeding an adopted infant.

Dear Mark: Full-Fat Dairy Roundup

dairy4Last 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 effect on weight gain. Next, I briefly go over the A1/A2 milk issue. Is it something you actually have to worry about? (Maybe.) After that, I discuss whether dairy has to be raw to be worth eating (or drinking), and I give my rationale for choosing the dairy that I do. Then I give my take on why the osteoporosis rates in the United States are high despite our high dairy consumption, followed by whether using inflammatory forms of dairy to heighten the post-workout spike in inflammatory markers makes sense. And finally, does a gluten intolerance make dairy more problematic?

Dear Mark: Gummy Vitamins, Heirloom Rice, and Regular Checkups

gummybearFor 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 the antinutrients. I also get into the somewhat counterintuitive role of antioxidants after exercise. Last, I give my opinion on the importance (or lack thereof) of getting regular checkups or physicals at the doctor just… well, because.
