Mitochondria, the powerhouses of our cells, are crucial for energy production and overall health. As we age, their efficiency declines, increasing the risk of serious diseases.

Mitochondrial dysfunction is linked to age-related conditions like cancer, dementia, type 2 diabetes, and cardiovascular diseases. These diseases often develop due to increased free radical production and oxidative stress caused by failing mitochondria. Free radicals can damage cell DNA, nerve cells, insulin-producing cells, and cholesterol particles, respectively increasing the risk of each disease.

Lifestyle interventions can significantly improve mitochondrial health. Regular exercise is shown to enhance energy production and reduce oxidative stress, even in older individuals. “The more active you are, the less this failure occurs, even if you are over 70,” states Steen Larsen.

Other potential strategies include intermittent fasting and coenzyme Q10 supplementation. Some studies suggest that intermittent fasting may positively impact mitochondria, although results vary. Coenzyme Q10, an antioxidant naturally present in mitochondria, may help reduce oxidative stress, particularly in older adults. However, Larsen advises caution with antioxidant supplements, as cells require some stress to strengthen.

Ultimately, exercise remains the most effective and scientifically supported method for maintaining healthy mitochondria. While research continues on other interventions, physical activity provides clear benefits for individuals of all ages and body types.
