Tea compound could help extend lifespan
A new study suggests that an antioxidant abundant in tea leaves could prolong the human lifespan. Chlorogenic acid, also found in prunes, potatoes and aubergines, is already known to improve brain function and reduce the risk of certain cancers. In an experiment focusing on roundworms that have a similar ageing process to mammals and humans, Chinese researchers have now found that it is also able to prolong the age of worms for up to the human equivalent of 175 years. The worms that were fed doses of chlorogenic acid were found to live up to 35 days, or about twice longer than usual. They also remained physically active for longer and benefited from more responsive immune systems. Scientists say that the findings may serve to develop foods and drugs containing chlorogenic acid as an ingredient.
