Reducing consumption of a protein found in fish and meat could
slow the ageing process and increase life expectancy, according to the research.
Scientists have long believed that an ultra low calorie diet - approximately
60 per cent of normal levels - can lead to greater longevity.
But now a
team of British researchers have discovered that the key to the effect is a
reduction in a specific protein and not the total number of calories.
That means that by reducing foods that contain the protein - such as meat, fish
and certain nuts - people should live longer without the need to cut down on
Dr Matthew Piper, from the Institute of Healthy Ageing at
University College London, said that a vegetarian diet could be one way to
achieve the effect.
