Research into ageing could also help in the battle against diseases such as Alzheimer's, it is suggested.
Professor Linda Partridge, director of the Institute of Healthy Ageing at University College London, believes tackling the causes of ageing will offer better prospects for dealing with the resulting diseases.
She pointed out that research on diseases associated with ageing are often done by separate groups of scientists.
"But by tacking the causes of ageing itself we could treat, or at least delay, a broad spectrum of conditions simultaneously," Professor Partridge added.
It has been suggested that drugs could replicate the effects of a healthy diet, increasing lifespan and targeting age-related diseases such as Alzheimer's.
Professor Partridge believes broad-spectrum preventative medicines could be used to increase the number of years people enjoy in good health.
Earlier this month the UK government was urged to consider further research into Alzheimer's disease.
The Alzheimer's Research Trust said if the onset was delayed by five years, the number who die from the condition could be halved.
