New research suggests that eating fewer calories could slow the ageing process and prevent lines and wrinkles. Scientists from the University of Gothenburg, Sweden, have found that sticking to a diet which sees a reduction in sugar and protein consumption, and ensures a healthy balance of vitamins and minerals could slow the ageing process and reduce the chances of developing cancer, dementia and type-2 diabetes.According to the study, lowering the intake of calories can boost levels of peroxiredoxin (Prx1), an enzyme which helps to reduce the levels of hydrogen peroxide which can make us look older. Eating fewer calories also boosted Srx1, the enzyme which repairs Prx1. This anti-ageing enzyme may also be linked to Alzheimers disease and Parkinsons, something scientists plan to look into further. Study author Mikael Molin, a post-doctoral research fellow at the University of Gothenburg, said: We are able to show that caloric restriction slows down ageing by preventing an enzyme, peroxiredoxin, from being inactivated. This enzyme is also extremely important in counteracting damage to our genetic material. Impaired Prx1 function leads to various types of genetic defects and cancer. Conversely, we can now speculate whether increased repair of Prx1 during ageing can counteract, or at least delay, the development of cancer.
