A large new study, conducted by a team of scientists from the University of Edinburgh in the UK finds a link between iron levels in the blood and lifespan. Scientists found that too much iron in the blood is associated with a higher risk of premature death.
The new research includes genetic information from over 1 million people across three public databases. The data analysis was focused on three key measures of aging: lifespan, healthspan, or years lived without diseases, and longevity, or living to very old age.
Data analyst Paul Timmers from the University of Edinburgh in the UK says: “We are very excited by these findings as they strongly suggest that high levels of iron in the blood reduce our healthy years of life, and keeping these levels in check could prevent age-related damage.”
A new research, published in the Journal of Internal Medicine, finds that consuming more fish and long-chain omega-3s reduces total mortality. However, scientists insist that not all cooking methods are good for that matter.
For the study, a team of researchers performed an analysis of data from NIH-AARP Diet and Health study, which included information on the dietary habits and health of 240,729 men and 180,580 women followed for 16 years.
The authors conclude: “Consumption of fish and [omega-3s] was robustly associated with lower mortality from major causes. Our findings support current guidelines for fish consumption while advice on non-frying preparation methods is needed.”
According to a report published in Nature, humans have reached their longevity limit.
The scientists say that despite life expectancy has been increasing during the last 100 years, it’s unlikely it will continue to rise any more than what it is right now. It is also extremely unlikely that any human is able to live for more than 125 years. Geneticist Jan Vijg from the Albert Einstein College of Medicine, New York, and his team executed this research. The researchers have analyzed aging trends in the USA, UK, France and Japan.
Jan Vijg says: “While there is no reason to think that the ongoing increase in maximum lifespan will end soon, the data strongly suggests that it’s already been attained and that this happened in the 1990s.”
A new study suggests that reading books can extend lifespan by up to 2 years. Moreover, the study says that the more often you read the better. The findings of the study have been published in the journal Social Science & Medicine.
Scientists have come to this conclusion after analyzing the data of 3,635 men and women who participated in Health and Retirement Study, a nationally representative sample of American adults aged 50 and older. They were followed-up for an average of 12 years and their survival rate was monitored during this time.
Compared to adults who did not read books, those ones who were reading books for up to three and a half hours each week were 17% less likely to die over the 12-years period follow-up, and those who read for more than three and a half hours weekly were 23% less likely to die.
Overall, adults reading books survived almost 2 years longer over the period of 12-year follow-up than non-readers.
