The popular story of how low-carb diets work goes something like this: Reducing your carbohydrate...
Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
Serotonin is a major regulator of mood and depression risk. These are important, vital roles, to be sure. Your mood describes how you experience and interpret the world. If it’s consistently bad, you’regoing to have a rough time. Yet, serotonin is much more than the “feel-good hormone.” It also influences sexual desire and helps us remember. It’s the precursor to melatonin, the neurotransmitter that allows us to sleep.
With conventional wisdom’s take on oral care, we’re left with a pretty superficial understanding of oral health. What if, for instance, cavities imply more than bad brushing habits? What if we changed the entire template from one focused on cosmetic and sensory criteria to an understanding founded on whole health principles? Answer: we’d be much closer to the truth.
Consider this. A recent study involving over 37,000 dental patients found that “patient-reported general health and risk factors were negatively associated with an overall composite oral health score,” with study authors noting their results supporting a “growing body of evidence linking oral and systemic health.” As for the particular health connections, you’d be surprised at the span of influence: cardiovascular disease, pneumonia, diabetes, even pregnancy issues.
For today’s edition of Dear Mark, I’m answering five questions from readers. First up, why isn’t hiking giving one reader the shifts in body comp they expected? Two, is there actually a way to mask the flavor of liver? Then I discuss a few unconventional testosterone boosters, followed by a brief treatment of the cooked, then cooled, then reheated potato. And finally, are there any dietary activators of sirtuin proteins?
As big-brained hominids, humans have the unique ability to think about the future. The very fact that we can perceive and plan for the time ahead has allowed us to conquer the earth, but it comes with a downside: anxiety. If extreme rumination on past events characterizes depression, worrying about imagined future scenarios describes anxiety.
This inherent capacity and human tendency to think ahead must be reined in and controlled. One way we can do that is make sure we’re getting enough of the nutrients that studies indicate may play an etiological role in anxiety.
Sure, they’re not exactly the sexiest body part, but it’s fair to say that life with substandard ear health would be notably less enjoyable. And as it happens, millions of Americans would be able to speak to that.
Research indicates that an estimated 1 in 5 folks have some form of hearing loss. This rate increases to 1 in 3 for age 65 and over, but some estimates put hearing loss great enough to impair communication even higher for the upper decades at around 40%. Perhaps even more alarming, close to 15% of American kids have some form of hearing loss. In teenagers, prevalence has jumped from 15% in 1994 to almost 20% in 2006. Unfortunately, that hearing difficulty will often go undiagnosed.
Hearing loss is, in fact, the third most common health condition in the country, right on the heels of arthritis and heart disease. And it’s getting worse. Between 2000 and 2015, the number of Americans with hearing loss has doubled, mirroring a worldwide increase of 44% over that same period.
But it’s not all about hearing. What about ear health? Our ears perform plenty more functions than just auditory reception. Let’s not forget that the ears are instrumental in influencing our emotions and state of mind, maintaining our sense of balance, and regulating pressure.
For today’s edition of Dear Mark, I’m answering several questions. First, if a person can’t have coffee but wants the benefits it provides to liver health, what else can they try? Next, what role does vitamin C play in glutathione production? Then, I explore how gelatin and collagen differ from each other, followed by a quick description of NAC. After that, I give my current favorite method for cooking greens, and end with a discussion of how breading meat with potato starch changes the meal.
