Carbon Dioxide lengthens life span

Over the past few months, I’ve published several articles discussing the remarkable health benefits of carbon dioxide (CO2), which is produced in the Krebs cycle in your mitochondria. CO2 is a driver of mitochondrial energy production, and improves the delivery of oxygen into your cells. It also protects against the harmful effects of lipid peroxidation.

It’s rather surprising that the benefits of CO2 have become forgotten considering its historical use. Asian cultures, for example, have a long history of using carbonated water for its health benefits.

The Romans recommended taking baths in naturally carbonated water for all kinds of ailments but especially arthritis, infertility and psychiatric ailments, and this practice extended well into the Middle Ages when monks prescribed it. To this day many visit natural hot springs, and the likely benefit in many of these springs is the CO2 content of the water.

In the 20th century, Russian scientists did loads of research on CO2, and to this day, many Russian clinics offer CO2 baths and other CO2 treatments. There’s even a suit that can be filled up with CO2, which then diffuses into your tissues. You’ll start feeling hot very rapidly and this is a sign of vasodilation, which is one of the cardiovascular effects of CO2.

It’s been shown that CO2 can, over the long term, reverse arterial calcification, as well as other kinds of damage caused by the aging process. In fact, while this may come as a shock to most people, I believe CO2 is one of the most effective longevity interventions available. It may also be a crucial component of cancer prevention and treatment, as discussed in one of my interviews with Georgi Dinkov.

Certain Bacteria Produce CO2 During Fermentation

CO2 is also part of the “magic” that makes fermented foods so good for you. During lacto-fermentation, certain lactic acid-producing bacteria break down sugars into acids, alcohol and CO2 (among other things). CO2 is what creates the fizziness in fermented foods like sauerkraut or pickles, while the acids create an environment with low pH that is free of oxygen, thereby preventing spoilage.

Lactic acid bacteria, such as Lactobacillus brevis — one of 16 Lactobacillaceae strains — also produce antimicrobial compounds such as bacteriocins that prevent the growth of harmful bacteria that can make you sick. The Conversation recently highlighted Lactobacillus brevis, referring to it as a “fermentation superstar” for all these reasons.1

Aside from fermented veggies, L. brevis is also found in raw milk, wine, sourdough bread and certain cheeses.2 It’s known to promote digestive health in general, and can help prevent and treat gastric ulcers by inhibiting Helicobacter pylori. Other health benefits of L. brevis include improved cognitive function and immune function.3

Health Benefits of L. Reuteri

Two other strains in the Lactobacillaceae family — L. reuteri4 and L. fermentum5 — are also CO2 producers. Like L. brevis, L. reuteri is well-known for its ability to promote gut health. It also upregulates systemic immune responses, thereby promoting wound healing, mental health, metabolism and myoskeletal maintenance,6 and has been shown to have “anti-aging” effects.

Research7 published in 2013 found that aged mice fed a commercially-available L. reuteri-containing probiotic yogurt experienced skin and fur changes that mimic the “peak health and reproductive fitness characteristic of much younger animals,” including a thicker dermis, and thicker, shinier, more lustrous coats. In contrast, age-matched controls that ate chow alone had dull fur and suffered from occasional alopecia and dermatitis.

The researchers pointed out that healthy-looking fur (and hair in humans) tend to be a sign of good fertility, and is a recognized sign of health in general:

“Taken together these facts lead us to hypothesize that probiotics may play a role in effecting the ‘glow of health’ associated with youth and reproductive fitness. Further, we postulated that feeding of probiotic organisms recapitulates these beneficial integumentary effects characteristic of youth within aged adult animals.”

Other documented health benefits of L. reuteri include:8

  • Antimicrobial effects
  • Immune-boosting and immune-regulating effects
  • Strengthening the intestinal barrier, thereby decreasing microbial translocation from the gut lumen to other tissues. As a result, a wide variety of diseases rooted in systemic inflammation may be ameliorated

Lactobacillus Inhibits Endotoxin Production

All Lactobacillus strains also inhibit the growth of gram-negative endotoxin-producing bacteria through competitive inhibition,9 and this is crucial for health in several respects.

Endotoxin, also known as lipopolysaccharide (LPS), is produced by gram-negative bacteria in your gut. As explained in several previous articles, endotoxin is one of several factors that destroy mitochondrial function, promotes glycolysis and, ultimately, cancer metabolism.

When complex carbs aren’t digested in your stomach, they travel down to the intestine where they feed these gram-negative bacteria, and as the bacteria grow, multiply and die, they release LPS, which can result in leaky gut, allergic reactions, organ dysfunction and even sepsis.

Endotoxin also catalyzes a series of metabolic reactions that convert tryptophan in your gut to serotonin, which at high levels is not good for your health. You do not want high levels of serotonin because it’s an antimetabolite, meaning it suppresses your body’s ability to create energy in your mitochondria in the electron transport chain, so you become tired and fatigued, your metabolic rate slows and you gain weight.

To address this vicious cycle, you need to heal and seal your gut. Beneficial bacteria such as Bifidobacteria and Lactobacillus, and beneficial yeast like Saccharomyces boulardii, can all help rein in the endotoxin production through competitive inhibition.

Probiotics such as these also strengthen your intestinal barrier (the “seal” part of “heal and seal your gut”) by increasing mucus production, stimulating release of antimicrobial peptides, and increasing tight junction integrity.10

At the same time, you also want to strictly limit your intake of refined sugar and most starches, as these types of carbs tend to feed the bacteria that produce endotoxin, especially if your microbiome is less than optimal.

How to Feed the Lactobacillus in Your Gut

The greater the diversity of your gut microbiome, the more likely you are to be able to maintain overall good health as the beneficial bacteria will maintain homeostasis and make sure opportunistic pathogens (commensal bacteria) won’t get the upper hand.

There are three primary ways to increase the number of Lactobacilli and other beneficial bacteria in your gut:11

  1. Consume fermented foods such as unpasteurized yogurt or kefir made from raw milk, sour cream and fermented vegetables such as sauerkraut.
  2. Take a high-quality probiotic supplement that contains one or more strains.
  3. Eat foods that promote proliferation of Lactobacilli, such as dietary fiber, Konjac flour, wheat bran, buckwheat, barley, apples, walnuts, artichoke and chokeberry.

    Makes sense to me

    As a comparatively recent convert to the benefits of yoga then, I notice that stress busting yoga breath retains CO2 in the lungs for longer. A relaxed count of 4 on the inbreath, a relaxed count of 8 on the outbreath, twice as long so CO2 held in the lungs

    It definitely works and it can be practiced any time any place. Want to chill out? Try that for 10 or twelve cycles

      Yes Pete, CO2 is very important in facilitating oxygen absorption into the body. It also immediately reduces high blood pressure. I came across this info from the work of the late Dr. Peat which was made available by Dr. Mercola recently. Extract below: BELOW IS SOME IMPORTANT INFORMATION on the importance of CO2 to human health and indeed all life as it regulates distribution of oxygen through the body.
      Dr. Mercola was instrumental in bringing to notice the work of the late Ray Peat a Biologist pictured above. Carbon dioxide (CO2) is a driver of energy production, as it improves the delivery of oxygen into your cells. CO2 also helps protect against the harmful effects of lipid peroxidation CO2 and lactate have opposing effects. Lactate is the by-product of metabolising glucose without oxygen in the cytoplasm.
      So, where lactate causes problems, CO2 has beneficial effects Elevated lactate production is a common theme in diabetes, Alzheimer’s, heart failure, shock and general aging. It promotes inflammation and degrades mitochondrial function. Conversely, low CO2 concentrations have been linked to epileptic seizures, muscle spasms, inflammation, hypothyroidism, stroke and clotting disorders
      All these issues, whether caused by elevated lactate or low CO2, can be successfully treated with CO2 therapies of various kinds, such as CO2 baths (where CO2 is pumped into the tub, much like bathing in carbonated mineral water) or adding CO2 into standard hyperbaric treatment
      Simpler ways to raise your tissue content of CO2 include breathing into a paper bag, having an adequate supply of calcium, and supplementing with salt, baking soda or carbonated beverages.
      In this 2010 interview, the late Ray Peat, a biologist and physiologist who specialized in the bio-energetic theory of health, reviewed some of the key benefits of CO2 and how it works within the human body.
      This article is a summary of the key points made in that interview. I apologize for the video quality. The video was recorded 13 years ago, and appears to have been shot on a cell phone. In 2010 the cameras were not very good. However, the audio is fine, and more importantly, this information is really hard to come by since Dr. Peat is no longer with us. Only 2,000 people had viewed it when I first saw it.
      I watched it four times as it is so good. I’m convinced optimising your carbon dioxide (CO2) level is one of the most important strategies you can do to slow down degeneration due to aging.
      On that point, I will be interviewing one of the leading breathing experts in the world, Peter Litchfield, Ph.D., who will educate us on why most breathing techniques don’t work, as they don’t address the underlying triggered breathing habits that lower CO2. CO2 is Crucial for Optimal Health CO2 is typically thought of as nothing more than a harmful waste product of respiration, and a “pollutant” that endangers the earth by raising global temperatures.
      The reality is that CO2 is a driver of mitochondrial energy production, and it improves the delivery of oxygen into your cells. It’s also essential for most life on Earth, plants in particular. In fact, CO2 appears to be a more fundamental component of living matter than oxygen
