A new study published in the American Journal of Clinical Nutrition suggests that people who eat large amounts of super-processed foods age faster. Telomeres are small segments of DNA-protein complex present at the end of the line chromosomes of ethyrocytes, which maintain chromosome integrity and control cell division cycles. Telomeres, silk grains, and replication origins are the three main elements of chromosome integrity and stability.
In addition to providing buffers for non-transcriptional DNA, telomeres protect the ends of chromosomes from fusion and degradation, play an important role in chromosomal location, replication, protection and control of cell growth and longevity, and are closely related to apoptosis, cell transformation and peronalization.
Telomeres are considered to be one of the hallmarks of biological age, reflecting the history of cell replication and replication potential. As the cells divide once, the telomeres of each chromosome become shorter one by one.
Superprocessed foods are processed foods based on processed foods, which usually contain more than five industrial preparations, and are high-sugar, high-fat, high-calorie foods, long-term consumption will increase the risk of cancer.
Scientists say super-processed foods are less nutritious than the same foods that are less processed. There is also a strong correlation between superprocessed foods and high blood pressure, obesity, depression, type 2 diabetes and certain cancers.
These conditions are usually associated with aging because they are associated with known oxidative stress and inflammation that affect telomere length. This also means that super-processed foods will accelerate the aging of the body.
To further test this fact, the scientists studied DNA samples from nearly 886 subjects over the age of 55 and looked at detailed data on their eating habits every two years and divided them into four groups based on their intake of super-processed foods.
It was found that subjects with higher intakes of ultra-processed foods were more likely to have a family history of cardiovascular disease, diabetes and blood lipid abnormalities. And they eat less olive oil, fruits, vegetables, solid foods related to the Mediterranean diet.
The researchers said the other three groups were 29 percent, 40 percent and 82 percent more likely to have shorter telomeres than the least-consuming group of super-processed foods. Eating three or more servings of “super-processed food” a day doubles the chance of telomeres being shortened.
