The Definitive Guide to Fats

Cholesterol usually gets the gold for most demonized nutrient, and fats undoubtedly take the silver. It’s time to confront the misunderstandings around fats.

When I switched from a high-carb, low-fat diet and started to eat healthy fat as a nutrient, my health rapidly transformed. As important as fat is to your body, the fact remains that not all fats are created equal.

A few fats, including but not limited to trans fats, deserve every bit of disparagement they get and then some. But many types of fats are beneficial, and we’d like to put in a good word for them. Here, we’ll go through good fats, harmful fats, and how to eat more of the best kinds of fats. At the end of this article, I’ve included a video explaining how to get more healthy fats and why you would want to in the first place.

Omega-3s: Everything You Need to Know

As a health-minded individual, you’ve no doubt gotten the memo that omega-3 fatty acids are important. You may dutifully eat your weekly servings of small, oily fish. Perhaps a fish oil pill is even part of your daily supplement routine. But do you know why?

Looking back, I used to write about omega-3s a lot in the early days of Mark’s Daily Apple (more than a decade ago, geez!). Since then, I’ve covered the topic here and there, but I thought it was time for a refresher. Today I’m going to focus on giving you a broad overview of their function and an update on the state of the research literature.

It would be impossible to cover all the reasons that omega-3s are important for health in a single post, nor all the areas of ongoing research. I’ll try to hit the big ones here. Let me know in the comments what else you’d like me to cover in future posts.

Natural Cold Remedies: What Works and What Doesn’t

No matter how much you wash your hands or clean up your diet and lifestyle, it’s hard to avoid the common cold entirely. Eventually, if you encounter other humans out in the world, you will catch a cold. Those of you with kids in school or daycare might feel like you spend more time sick than you spend healthy, especially in the winter months.

Given the inevitability, we all have a shared interest in learning how to beat a cold as quickly as possible. There’s no shortage of folk remedies out there—everyone’s grandma probably had her own tried and true method of kicking a col. But which natural cold remedies actually work?

Let’s look at some of the most popular recommendations for natural cold remedies, distinguishing between those that could help you get better more quickly, ones that will at least provide some symptom relief, and ones that won’t hurt but might not help.

The Definitive Guide to Inflammation

Inflammation is your body’s response to infection and injury. When something triggers an inflammatory response, the immune system kicks into gear, isolating the area, removing harmful or damaged tissue, and beginning the healing process. “Inflammation” refers to both the immune processes happening under the surface and the outward signs of an inflammatory response—symptoms like pain, swelling, or fever.  Inflammation gets a bad rap in the alternative health world: “The root of all chronic illness!” This is true to some extent. Name a disease, and inflammation is involved.   Crohn’s disease, major depression, heart disease, arthritis—all inflammatory. Every autoimmune disease—inflammatory, involving an inflammatory response directed at your own tissues. Even obesity is inflammatory, with fat cells literally secreting inflammatory cytokines. Yes, but the story is more complicated than that. Inflammation is, after all, 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.  The popular refrain that “inflammation is bad” misses the fact that inflammation is necessary and beneficial in certain circumstances and in the right amounts. Where we run into problems is when there is too much for too long, as is so often the case. So how do you know when the line between helpful and harmful has been crossed? What Causes Inflammation? In order to understand what causes inflammation, we first need to distinguish between acute inflammation and chronic inflammation: Acute Vs. Chronic Inflammation Acute inflammation Acute inflammation is the body’s relatively brief response (lasting several days or less) to a specific injury or illness. All sorts of things can cause an acute inflammatory response, including  Trauma or injury, whether serious (car accident, stabbing, broken bone) or trivial (paper cut) Infection by bacterial or viral pathogens Burn (including from the sun) Chemical irritant Allergic reaction When an injury or invasion occurs, the body launches a defense involving the vascular system (veins, arteries, capillaries), immune system, and cells local to the injury. As a result, you’ll likely experience one or more of the five signs that an acute inflammatory response is underway: heat, redness, swelling, pain, or a loss of function.  Heat, redness, and swelling signal that leukocytes (white blood cells) have arrived to clean up the injury site, mop up pathogens, and oversee the inflammatory process. Pain and immobilization remind you—or force you—to proceed with caution, lest you re-injure the area. Although annoying, these symptoms are only temporary. And they’re a small price to pay. Without acute inflammatory processes, we would quickly succumb to even minor illnesses and injuries.   But not all acute inflammation is the result of something harmful. Some things that cause acute inflammation are actually good for us. Sun exposure is one example. Exercise is another. Immediately after a single hard workout, inflammatory markers go up because exercise stresses the body—but in a beneficial way. The short-term damage that exercise induces allows us to be stronger, fitter, … Continue reading “The Definitive Guide to Inflammation”

Dear Mark: EVOO, Supplements, Autoimmune Arthritis, Sauna, Keto Camping, Ketones for Autoimmune

For today’s edition of Dear Mark, I’m answering another round of questions asked by Twitter followers. First up is a three-parter, including a query about extra virgin olive oil, one about supplements everyone should take, and one about autoimmune arthritis in an athlete. Second, I cover whether sauna is a hormetic stressor or a way to relax (or both). Next, I give my recommendation for staying keto or carnivore while camping (it’s a quick one). And finally, I explore a potential protocol for using exogenous ketones to curb autoimmune inflammation.

Dear Mark: Oily Fish Limit, Diet and Posture, Acid Reflux, Whey Replacement, Milk and Fasting, and Remembering to Live

For today’s edition of Dear Mark, I’m answering six questions from some of my Twitter followers. Yesterday, I asked the community for questions and got some great ones in return. For instance, how much oily fish should one eat each week? And how does diet and nutrition influence posture and coordination? Third, how should a low-carb diet affect acid reflux? Fourth, is there a good replacement for whey protein? Fifth, does milk with your coffee break a fast? And sixth, how does one stop viewing and using food as an indulgence? I’ll get to the rest next time.

Dear Mark: Does Chicken Cause Cancer, Should You Neuter, Dog Collagen, and Skipping Dinner

For today’s edition of Dear Mark, I’m answering a few questions. First came in from an email and regards a new study showing a link between chicken eating and several types of cancers (melanoma, prostate cancer, non-Hodgkin’s lymphoma) among British adults. What do I think of the study? Second, did I really tell people not to neuter or spay their dogs? Third, can dogs take collagen powder, and if not, are there any alternatives? And last, I address a comment about early time restricted feeding.

What’s TMAO, and What Does It Have to Do With My Health?

With the last few weeks’ definitive guide and follow-up on fish, a reader asked me about trimethylamine N-oxide, or TMAO. What is it?

TMAO is the latest justification given for why eating meat just has to be bad for you. Saturated fat didn’t take. Animal protein didn’t work. Iron was a dud. IGF-1 hasn’t panned out. Methionine isn’t enough. So now they’re using TMAO to convince you not to eat that steak.

How’s it supposed to work?

Dear Mark: Is Fish Enough, Do Carnivores Really Need It, and More

For today’s edition of Dear Mark, I’m answering several questions you guys asked in response to the fish post from last week. First, is being a pescatarian enough? Can you get what you need from seafood without eating meat, dairy, or eggs? Next, how important is fish for a carnivore? Third, how’s that Whole Foods farmed salmon? Healthy or not? Then I write a bit about canned cod liver, the underrated seafood, followed by a short blurb about whether we should worry about wild salmon sustainability as well as a question about taking chlorella to reduce heavy metal absorption from fish.

The Definitive Guide To Fish: Why and How To Eat It

In nutrition, there are very few universal consensuses. Conventional wisdom says that fat makes you fat and whole grains are essential, and millions of people agree, but the ancestral health and keto communities (and reality) disagree. Primal and keto folks don’t worry much about saturated fat and limit polyunsaturated fat; conventional health advocates do the opposite. The opinion on meat intake varies wildly, with some people suggesting we eat nothing but red meat, others recommending “palm-sized” pieces of strictly white meat, and still others cautioning against any meat at all. Pick a food and you can find a sizable group that hates it and a sizable one that loves it. You can find researchers who spend their lives making the case against it and researchers who spend their lives making the case for it.

But not fish. Fish is about as close to a universal as any food. Barring the vegans and vegetarians (some of whom, however, are sneaking wild salmon when their followers aren’t watching), everyone appreciates and extols the virtues of eating seafood. Including me.
