We’re diving into real nutrition in the wake of Nutrition Week (14-20 October—did you miss it too?!), let’s shine a light on one of the most crucial, yet often overlooked, parts of our health—our mitochondria. These tiny powerhouses, known as the “little engines” of our cells, are responsible for converting nutrients into energy. Keeping them hydrated and fueled with real nutrition is key to long-lasting vitality and disease prevention.
The average adult has approximately 37.2 trillion cells, and each cell contains between 100 to 10,000 mitochondria, depending on the cell type and its energy needs. Cells that require more energy, like muscle cells, liver cells, and neurones, tend to have a higher number of mitochondria. On average, it’s estimated that the human body houses 500 to 2,000 mitochondria per cell, making the total number across the body reach the trillions!
Why Mitochondria Need Saturated Fat and Essential Nutrients
Mitochondria thrive when nourished by healthy fats and essential nutrients. Saturated fats, in particular, are vital for keeping these cellular engines lubricated and running efficiently. Foods rich in saturated fat like grass-fed butter and freeze-dried beef suet provide a powerhouse of energy. Beef liver, a now-known superfood, is packed with B12, an essential multivitamin that fuels energy production. But B12 isn’t the only star in beef liver; it’s loaded with a host of other nutrient and mineral “friends,” including folate, iron, and vitamin A, which are crucial for supporting mitochondrial function [1].
Another key nutrient for your mitochondria is iodine, best sourced from clean, organic kelp. Iodine helps regulate thyroid function, which plays a significant role in mitochondrial energy production [2]. Without enough iodine, mitochondria can falter, leading to energy dips and long-term health consequences.
The Dangers of Ultra-Processed Foods
Ultra-processed foods are a major threat to mitochondrial health. These nutrient-depleted, additive-laden products can dehydrate and damage your mitochondria over time. When mitochondria become compromised, they struggle to produce energy, eventually dying off. This cellular decline has been linked to the rise in conditions like diabetes, autoimmune diseases, and neurodegenerative disorders such as Alzheimer’s and Parkinson’s—conditions that are becoming more prevalent today [3] [4].
Sunlight – The Perfect Morning Kick-Start
Consuming real nutrition isn’t the only factor in supporting mitochondrial health. Sunlight plays a vital role in fueling your body and brain, acting as a natural reset for your biological circadian clock. Getting morning sun, especially at sunrise, helps kick-start your metabolism, improves sleep patterns, and boosts energy levels throughout the day. Sunlight exposure signals your mitochondria to ramp up energy production, keeping you energized and focused [5] [6].
How to Nourish Your Mitochondria
- Eat real, whole foods: Prioritise nutrient-dense options like beef liver for essential vitamins and minerals, and kelp for iodine.
- Incorporate healthy fats: Keep your mitochondria hydrated with quality saturated fats like grass-fed butter and beef suet.
- Limit ultra-processed foods: Avoid foods that can dehydrate and damage your mitochondria. We all know which foods these are—the ones lining the central aisles of the supermarket!
- Get morning sunlight: Start your day by seeing the sunrise to align your body’s circadian rhythms and boost mitochondrial health.
By focusing on real nutrition and daily sunlight, you can give your mitochondria the support they need to keep your body thriving for years to come. Support your mitochondrial health and optimise your health – and longevity! For a comprehensive list of what foods repair mitochondria read the associated blog here.
