A new study by the US researchers has found that intake of a Mediterranean diet may lead to longevity as it helps in keeping people genetically younger.
According to the researchers, an ideal Mediterranean diet may help in stopping the DNA code from scrambling with the aging.
A Mediterranean diet consists of fresh vegetables, fruits, olive oil and fresh fish.
For the study, the researchers involved nearly 5,000 nurses from Boston and followed their health for over more than a decade. It was found that the nurses who strictly followed a Mediterranean diet showed fewer signs of ageing in their cells.
The researchers keenly observed the tiny structures known as telomeres that help in safeguarding the ends of chromosomes, which stores our DNA code.
With aging, our cells divide and our telomeres get shorter. This leads to the weakening of their structural integrity, as a result of which cells to stop dividing and die.
The nurses who strictly followed a Mediterranean diet had longer and healthier telomeres.
Shorter telomeres have been associated to a range of age-related diseases, like heart disease, cancers and several others.
The Mediterranean diet has also been associated with several gains like cutting the risk of heart disease or other cardiovascular ailments.
Dr Mike Knapton, of the British Heart Foundation, said, “These results reinforce our advice that eating a balanced and healthy diet can lower the risk of developing heart disease”
The study was published in the British Medical Journal.
