Dear Mark: Coronavirus Edition 2 – COVID-19 Questions, Answered

For today’s edition of Dear Mark, I’m answering more COVID-19 (coronavirus) questions. If you’re getting tired of coronavirus content, I understand, but I also owe it to my readers to give them my take on the research—and the questions have been pouring in. Information is coming out at a rapid pace and there are a lot of wild claims and recommendations flying around. With any luck, we’ll all be able to focus on something else in the near future. Thanks for your understanding.

Soothing Soup, Bone Broth, and Tea Recipes

When viruses and bacterial infections swirl around us, and especially during the winter and early spring months when the weather can seesaw between sunny and pleasant, and thundering and soggy, warm soups, bone broths, and teas can fortify and evoke warm fuzzy feelings (even if they’re fleeting until the next bowl or mug). These soup, bone broth, and tea recipes can help soothe when you’re feeling worn out or ill, and warm you up when the weather won’t.

Dear Mark: Synthetic Peptides

For today’s edition of Dear Mark, I’m answering one question from a reader. It’s all about synthetic peptides, small chains of amino acids with potentially huge effects on your health and physiological function. In most cases, these synthetic peptides are based on naturally-occurring compounds found in the human body. Scientists isolate the “active component” of the compound and whip it up in a lab by stringing together the right amino acids. Many of these peptides are available for purchase online, strictly “for research purposes.” But people are using them.

Are these safe for humans? Are they effective?

Dear Mark: Homocysteine, Some Kefir Questions, and the Stress of Worrying

For today’s edition of Dear Mark, I’m answering a bunch of questions from readers. The first one concerns another inflammatory marker, homocysteine. How could CRP be low but homocysteine be high? What could cause that? Next, I answer a barrage of kefir questions, including ones on kefir carb counts, pasteurized kefir, and water and coconut kefir. Finally, I address the elephant in the room: stressing out about your diet.

12 Natural Cold Remedies Examined: What Works and What Doesn’t

Cold season is upon us. Vitamin D levels are down. People are cloistered indoors. Kids are walking petri dishes. Drug stores are advertising free flu shots. It’s that time of year. I’m sure a few of you are even sniffling as you read this, or maybe trying to ignore the pain of swallowing with a sore throat.

Colds seem like an inevitability, maybe not so much since you’ve cleaned up your diet, but nothing is 100% fool-proof. You will get sick. You will catch a cold. Or someone close to you will. What can you do for yourself? For your sick kid or partner? Are there any natural cold remedies that actually work?

Let’s look at them.

The Definitive Guide to Inflammation

Inflammation gets a bad rap in the alternative health world: “Inflammation causes heart disease, cancer, and autoimmune disease! It’s at the root of depression.” These are all true—to some extent.

Name a disease, and inflammation is involved.

Crohn’s disease is inflammatory.

Major depression is inflammatory.

Heart disease is inflammatory.

Autoimmune diseases, which involve an inflammatory response directed at your own tissues, are inflammatory.

Arthritis is inflammatory.

Even obesity is inflammatory, with fat cells literally secreting inflammatory cytokines.

Yes, but the story is more complicated than that. Inflammation, after all, is a natural process developed through millions of years of evolution. It can’t be wholly negative. Just like our bodies didn’t evolve to manufacture cholesterol to give us heart disease, inflammation isn’t there to give us degenerative diseases.

Keto and Cancer: Where Do We Stand?

The ketogenic diet has exploded in popularity over the last few years. Hordes of people are using it to lose body fat, overcome metabolic diseases, improve their endurance performance, attain steady energy levels, make their brain work better, and control seizures. And increasing numbers of researchers and personal experimenters are even exploring the utility of ketogenic diets in preventing and/or treating cancer. After all, back in the early part of the 20th century, Warburg discovered an important characteristic of most cancer cells: they generate their energy by burning glucose. If a particular cancer loves glucose, what happens if you reduce its presence in your body and start burning fat and ketones instead?

It’s taken a while, but the research community is finally beginning to take a few swings at this and similar questions.

HIIT vs. HIRT: Reducing Workout Stress To Increase Fitness

The fitness world is booming these days. You can see it in the popularity of CrossFit boxes, obstacle course and endurance events, and record-breaking gym construction. It’s encouraging. Inspiring even. But there’s also a downside to the rising gym memberships and event registrations. There are still too many people dealing with recurring patterns of breakdown, burnout, illness and injury. More people are trying to do the right thing, but the flawed approaches they often gravitate to end up derailing them.

Nonetheless, there are changes afoot. It’s an evolution of thinking that’s slowly spreading its way through fitness circles. More forward-thinking coaches, trainers, and researchers are helping right the wrongs of the fitness boom with a general rejection of the “more is better” approach for one that respects the importance of balancing stress and rest, one that moves toward an intuitive approach to workout planning.

Life In the Sanitized Bubble (Or Why Probiotics Are So Important)

For the vast majority of human history (and prehistory), men, women, and children had near-constant contact with the natural world around them. They were walking on the ground. They were playing in the dirt. They were digging for roots and grubs. They were eating with their hands. They were field dressing animals and wiping their hands on the grass. Nothing was sterilized; the tools to sterilize the environment didn’t exist. You could boil water, but that was about it. Bacteria were everywhere, and humans were constantly ingesting it. Even as babies, preindustrial infants nursed for almost four years, so they were getting a steady source of breastmilk-based probiotic bacteria for a good portion of their early lives.

Recovery Workouts: Two Simple But Powerful Ways to Speed Fitness Recovery

For my entire athletic career, I considered the gold standard of recovery to be sleeping, resting on the couch watching T.V., and generally being still and inactive. Come on, what could be more effective than couch potato mode to recover from the hormonal and inflammatory stresses of marathon training runs or long days of extreme swim-bike-run workouts? I’m kidding (mostly), but it’s not a total exaggeration. Our understanding of fitness recovery has grown exponentially since I was in the elite arena, and it’s exciting to see new and better approaches taking root that genuinely speed recovery and stave off burnout. I’m sharing two such techniques today. They’re simple, mostly free, and accessible to anyone with the most basic fitness opportunities and venues.
