Dear Mark: Safe Tick Repellent, Fish Intake on Mediterranean Diet, and Therapeutic Value of Wine

For today’s edition of Dear Mark, I’m answering a few questions from recent comment boards. First, with all the scary tick-related news coming out lately, are there any non-toxic tick repellents that actually work? Are there essential oils that repel and/or kill ticks? Is there a safer way to use insecticides? Next, were the people in the Mediterranean keto study actually eating a kilo of fish on their fish days? And is the wine an important part of the Mediterranean diet? Is the wine therapeutic or just for pleasure?

Dear Mark: Collagen vs Whey Follow-Up

For today’s edition of Dear Mark, I’m answering questions from last week’s Collagen vs Whey post. You guys had a lot of questions, mostly about collagen, and I’m here to answer them. Can collagen help with plantar fasciitis? Should you take collagen and whey together in the same smoothie, or do they cancel each other out? If a person can’t have whey, is there an equivalent protein powder source? Is glycine a good replacement for collagen? What about liquid whey from raw milk—how does it compare to powdered whey? If I wanted to get my glycine from foods, what would I need to eat and how much of it?

Dear Mark: Increased Red Meat, Reduced Carb, Increased Death?

For today’s edition of Dear Mark, I’m answering three questions. First, what’s the deal with the new Harvard study claiming that eating more red meat increases the death rate? Does it actually prove this? Second, how about the one claiming that reduced carb diets also increase death? Should you worry? And finally, why do I recommend eating locally farmed farmer’s market produce, even if it isn’t organic?

I’m addressing questions about alcohol, uniform carb allowances versus personalized, potassium supplementation, salt appetite, salt water, electrolytes after the transition, whether fruits fit in, and why I don’t count above-ground non-starchy vegetables.

Dear Mark: CBD Edition

For today’s edition of Dear Mark, I’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re all piecing things together based on limited data—which, I suppose, is the fundamental human experience.

Dear Mark: What Breaks a Fast Follow-Up

For today’s edition of Dear Mark, I’m answering a round of questions drawn from the comment section of the “What Breaks a Fast” post. You folks had tons of follow-up questions about whether other types of foods or compounds break a fast. Does a teaspoon of honey? Does elevated insulin from BCAAs? Does coconut milk? Does pure prebiotic fiber? What about longer fasts—are they recommended? And how about unsweetened cocoa powder? What explains my ability to predict your questions? Do sausages break a fast? Does liquor? How should you exercise? (For questions on supplements, check out this week’s feature: “What Breaks a Fast: Supplements Edition.”)

Dear Mark: Protein Efficiency in Seniors, Earned Carbs, Hardgainer with Limited Time

For this week’s edition of Dear Mark, I’m answering three questions from readers. First, is the reduced protein efficiency in older adults due to inactivity, or is it something inherent to the aging process, or both? Second, how does a person know if they’ve actually “earned” any carbs? Does everyone on a keto diet earn carbs by virtue of exercising, or is there more to it? And finally, how can a hardgainer with a packed schedule all week long and limited gym time maintain what little muscle mass he’s managed to gain?

Dear Mark: Fasting, Training, and Growth Hormone; Wear and Tear on the Arteries

For today’s edition of Dear Mark, I’m answering a couple of questions from the comment sections of the last couple weeks. First, it’s been established that fasting and exercise both raise growth hormone. What about fasted exercise—does that have an even stronger effect? And what about continuing to fast after your fasted workout? Then, I discuss the inevitability (or not) of wear and tear on the arteries from blood flow-induced shear stress. Is shear stress “bad,” or do certain factors make it worse?

Let’s dig in.

Dear Mark: How Does LDL Even Penetrate the Arteries, New Zealand Farmed Salmon, Elevated Ferritin

For today’s edition of Dear Mark, I’m answering three questions. First, can LDL actually infiltrate the arteries, or is there more to the story? Malcolm Kendrick says there’s more to the story, so I dig into some literature to see if they corroborate his position. Second, is New Zealand farmed salmon good to eat? And finally, what should you do about elevated ferritin levels—and why else might they be elevated if not because of your iron?
