Every day we recommend to our clients and our Mobile Physiotherapy team to eat several different types of fruit. One of our favourite is Pomegranate, and for good reason. Read below.
As we age, our cells increasingly struggle to recycle their powerhouses. Called mitochondria, these inner compartments are no longer able to carry out their vital function, thus accumulate in the cell. This degradation affects the health of many tissues, including muscles, which gradually weaken over the years. A build up of dysfunctional mitochondria is also suspected of playing a role in other diseases of aging, such as Parkinson’s disease.
The scientists identified a molecule that, all by itself, managed to re-establish the cell’s ability to recycle the components of the defective mitochondria: urolithin A. “It’s the only known molecule that can relaunch the mitochondrial clean-up process, otherwise known as mitophagy,” says Patrick Aebischer, co-author on the study. “It’s a completely natural substance, and its effect is powerful and measurable.”
The team started out by testing their hypothesis on the usual suspect: the nematode C. elegans. It’s a favorite test subject among aging experts, because after just 8-10 days it’s already considered elderly. The lifespan of worms exposed to urolithin A increased by more than 45% compared with the control group.
These initial encouraging results led the team to test the molecule on animals that have more in common with humans. In the rodent studies, like with C. elegans, a significant reduction in the number of mitochondria was observed, indicating that a robust cellular recycling process was taking place. Older mice, around two years of age, showed 42% better endurance while running than equally old mice in the control group.
