Ageing with attitude: Dr John McKenna’s formula for cancer prevention

A traumatic experience served as a turning point for Dr John McKenna, who no longer works long shifts or in stressful environments, says Margaret Jennings.

ALTHOUGH Wexford-based medic, Dr John McKenna, has written several books on the importance of nutritional health, it was learning to deal with his own suppression of emotion that was a turning point in his life.

The 64-year-old father of four, who has a new book out, What You Can Do To Prevent Cancer, places a huge emphasis on the quality of the water we drink and the food we eat, for maintaining good health.
