This diet promotes healthy aging in women

A diet rich in fruits, vegetables and whole grains, as well as low in added sugar, sodium and processed meats, may promote cellular health as women age, according to a new study.

A diet rich in fruits, vegetables, and whole grains, as well as low in added sugar, sodium, and processed meats, may promote cellular health as women age, according to new research published in the American Journal of Epidemiology.

“The key takeaway is that following a healthy diet can help us maintain healthy cells and avoid certain chronic diseases. Emphasis should be placed on improving the overall quality of your diet rather than isolating individual foods or nutrients,”explained lead author Cindy Leung, assistant professor of nutrition at the University of Michigan School of Public Health …

The researchers used telomere length to measure cellular aging. Telomeres are DNA-protein structures located at the ends of chromosomes that contribute to the stability and protection of DNA. Age is the strongest predictor of telomere length (they shorten during each cell cycle).

However, recent research has shown that telomere contraction is possible due to behavioral, environmental, and psychological factors. Shorter telomeres are associated with an increased risk of heart disease, type 2 diabetes, and certain cancers.

The researchers studied the diets of 4,758 healthy adults between the ages of 20 and 65. They compared the quality indices of four evidence-based diets - Mediterranean, for the treatment of hypertension, and two other diets developed by the US Department of Agriculture and the Harvard THChan School of Public Health.

For women, with higher scores for each of the indices, there was a strong relationship with telomere size - they turned out to be longer.

“We were surprised that the results were comparable regardless of the Diet Quality Score we used,” said Lune. - All four diets emphasize eating lots of fruits, vegetables, whole grains and plant proteins and limiting sugar, sodium, and red and processed meats. Overall, the results show that longer telomeres are associated with adherence to these guidelines, and the risk of serious chronic disease is reduced.”

Study co-author Elisa Epel, professor of psychiatry at the University of California, San Francisco, said: “The commonality of all healthy dietary models is that they are antioxidant and anti-inflammatory diets. They create a biochemical environment favorable for telomeres."

For men, the results were similar, but not statistically significant.

“We've seen some gender differences in previous studies on nutrition and telomeres,” Lun said. - In our study, as in previous studies, men tended to have lower dietary quality scores than women. Men also had higher intake of sugary drinks and processed meats, both of which were associated with shorter telomeres in previous studies. It is possible that not all foods affect telomere length equally, and you need more protective foods to offset the harmful effects of others. However, more research is needed to explore this deeper."
