How watercress can help prevent DNA damage during exercise?
The 2012 study into DNA protection after exercise
In 2012 Doctor Fogarty et al widened the research into the powerful properties watercress possesses in preventing DNA damage by examining its affect in an exercise environment.
The study used a sample of ten ‘healthy’ males who were required to consume 85g of watercress daily for 8 weeks. The participants were then asked to engage in high intensity exercise on a treadmill. This was compared to a control group with the same program of activity where no watercress was to be consumed, as well as a further group who consumed watercress acutely two hours before exercise.
The results found that exercise increases DNA damage, as well as increasing lipid peroxidation, whilst watercress consumed over 8 weeks or for 2 hrs before exercise reduced DNA damage as well as lipid peroxidation. This provides support for the belief in the powerful protective effects of this leafy green vegetable and highlights its contribution in mitigating exercise induced DNA damage. Commenting on his previous research and future expectations for watercress, Dr Fogarty said:
