You’ve in all probability heard the phrase, “The mitochondria are the powerhouse of the cell.” However what does that imply? Why must you care? I’m right here to elucidate why our mitochondria perform are important to our well being and why we must always give attention to them to extend longevity. 

What Are Mitochondria?

Your physique is made up of trillions of cells that come collectively to make your tissues, organs, and extra. Particular organelles exist inside these cells to assist them do their job. One such organelle is the mitochondrion, which you’ll be able to consider as a bit power manufacturing facility. That’s the place the time period “powerhouse” comes from — it’s fairly actually a home to make energy. The mitochondria produce 90% of the power utilized by our our bodies.

To provide this power, our mitochondria want gasoline. They use oxygen from the air we breathe and vitamins from the meals we eat to create adenosine triphosphate (ATP), our physique’s power foreign money. In different phrases, the carbohydrates, proteins, and dietary fat you eat are absorbed and transformed by the mitochondria into power. Your cells and tissues use that power to perform.

The assorted tissues inside your physique have differing portions of mitochondria in every cell. The tissues that require essentially the most power to perform, comparable to your coronary heart, liver, mind, muscle tissues, and brown fats, comprise essentially the most mitochondria. For instance, an energetic muscle cell comprises as much as 3000 mitochondria per cell. Sadly, mitochondria don’t perform optimally ceaselessly. Over time, they turn into dysfunctional, and this decline is a trademark of getting older1

How Can I Hold My Mitochondria Wholesome and Vibrant?

When mitochondria turn into too broken to provide power in the way in which we’d like them to, they start to interrupt down into fragments. To protect the power manufacturing course of and maintain total mitochondrial effectivity as excessive as doable, our mitochondria then endure a recycling course of referred to as mitophagy. Mitophagy is a sort of autophagy, or a course of that permits our physique to reuse pointless mobile elements to rejuvenate itself. Throughout mitophagy, our our bodies filter these damaged mitochondria fragments and recycle them into contemporary mitochondria which might be able to producing power effectively once more. This manufacturing of recent mitochondria is known as mitochondrial biogenesis. 

Sadly, mitophagy turns into much less environment friendly as we age and expertise stress from our environments. We accumulate extra mitochondrial particles and have total decrease power manufacturing. Fortunately, researchers have discovered three avenues to stimulate mitophagy. 

This isn’t an alternative choice to skilled medical recommendation. See your major care doctor when making adjustments to your way of life.

The Three Methods We Can Enhance Mitochondrial Operate Well being

1. Train

You already know that there are various causes to have interaction in common train, together with advantages to your cardiovascular, pulmonary, psychological, and metabolic programs. However do you know that many of those advantages are literally as a result of train bettering our mitochondrial perform?

For instance, endurance coaching induces mitochondrial biogenesis, which subsequently will increase mitochondrial density (extra mitochondria per gram of tissue) 2. Larger mitochondrial density means an enhanced capacity to provide power. Along with selling mitochondrial biogenesis, train triggers mitophagy3 to take away the buildup of broken mitochondria, making area for the regeneration of higher-functioning organelles. 

2. Food regimen

The primary option to promote mitophagy via food regimen is to make use of a technique referred to as intermittent fasting (IM) or time-restricted feeding (TRF). This requires specifying a window of time every day for fasting. Though the proof has been blended on the efficacy of IM/TRF for well being4, weight administration5, and athletic efficiency6, there’s overwhelming proof that means IM/TRF induces mitophagy7. This means that IM/TRF might be a useful technique to advertise longevity via your mitochondria. 

Nevertheless, fasting will not be at all times acceptable or sustainable for everybody. Skilled athletes, for instance, have grueling schedules with excessive coaching hundreds that require a extra constant consumption of vitamins and energy to maintain up with power expenditure and promote restoration. 

The second technique to enhance mitochondrial well being is to emphasise nutrient-dense fruit and veggies in your each day consuming habits. These are excessive in polyphenols, antioxidants, and different important vitamins that promote mitochondrial well being. They’re additionally low in saturated fat and added sugar, each of which may harm your mitochondria and be dangerous to your total well-being. 

In fact, there could be points with diet-based methods. For most individuals, following a nutritious diet is a problem. Second is the difficulty of bioavailability, which means your physique’s capacity to soak up the vitamins from the meals that you simply eat. For instance, the bioavailability of polyphenols has been proven to differ significantly8,9, so it’s doable to eat a food regimen filled with polyphenols and antioxidants whereas solely absorbing a small fraction of these vitamins. In these circumstances, supplementation could also be mandatory.

3. Dietary supplements

Inside the final 20 years, there was a novel discovery in relation to optimizing mitochondrial well being: a nutrient derived from pomegranates referred to as Urolithin A (UA). UA is useful for mitochondrial well being as a result of, like train and intermittent fasting, it stimulates mitophagy10,11

UA is a postbiotic, which means your intestine microbiome naturally produces it while you eat its precursor meals. These precursor meals embody pomegranates, walnuts, and sure berries, that are all excessive in ellagitannins (a sort of polyphenol). Nevertheless, just like the aforementioned bioavailability challenge, analysis has proven that solely about 30% of individuals have the suitable intestine microbiome to transform ellagitannins into UA12. And even amongst those that can produce UA, most don’t commonly eat sufficient of the precursor meals to see the advantages. This leaves supplementation as one of the best technique for many of us.

By mitophagy mechanisms, UA dietary supplements have been proven to enhance muscular power and endurance in each older13 and middle-aged14 adults. Moreover, there’s rising proof in pre-clinical fashions for its constructive impression on cartilage degeneration15 and immunity16, in addition to mind well being17.

Prioritizing Mitochondrial Operate

Most of us don’t give a lot thought to our mitochondria, however they play a significant position in our muscular well being and longevity. Anybody trying to optimize their well being or efficiency ought to take into consideration easy methods to help these energy-producing organelles. By using focused train, food regimen, and supplementation methods, you possibly can maintain your mitochondria and muscle tissues vigorous.
