Energy balance
Reactive Oxygen Species (ROS) are not the primary cause of aging; instead, they are a consequence of mitochondrial dysfunction, and moderate ROS increases can extend lifespan via mitohormesis.
Avoid excessive antioxidant supplementation that might blunt the adaptive benefits of exercise. Embrace moderate metabolic stress (like exercise) which generates ROS as a signal to improve mitochondrial efficiency and longevity.
GoodRefutesHIGH confidence
increased ROS production was shown to extend lifespan in both yeast and Caenorhabditis elegans... mtDNA mutations that do not cause oxidative stress accelerate aging in mice... Together, these findings implicate that increased ROS generation or oxidative stress is not the primary or initial cause, but rather a consequence of aging
Why this rating
Strong evidence from model organisms (yeast, worms, mice) challenges the human-centric free radical theory.

- Mitochondrial dysfunction, driven by the accumulation of somatic mtDNA mutations and altered dynamics (fission/fusion imbalance), is a primary hallmark and causal driver of aging and age-related pathologies, rather than merely a consequence.Good
- Maintaining mitochondrial dynamics (balance of fission and fusion) and quality control (mitophagy/biogenesis) is critical for preventing age-related metabolic diseases and neurodegeneration.Good
