Eating too much salt can lead to increased blood pressure and increased risk of heart disease and stroke. At the same time, according to the British “Daily Telegraph” report, a new study in the United States found that eating too much salt will accelerate the process of human cell aging.
In the new study, scientists from the University of Regent in Georgia, USA, divided 766 14- to 18-year-old juvenile participants into different groups according to sodium intake. The daily intake of salt below 5 grams was low salt group, and more than 10 grams was high. Salt group. Comparative studies have found that the telomere length of adolescents who eat the most salt is significantly shorter than those who eat the least salt, especially those who are overweight.
Dr. Zhu Haidong, head of the new research, said that telomeres are DNA repeats at the ends of linear chromosomes. In normal human cells, telomeres can be gradually shortened as cells divide. When the telomeres are too short, the cells stop dividing and apoptotic. This condition is more common in patients with senile diseases such as heart disease, cancer, and type 2 diabetes.
Dr. Zhu pointed out that a number of studies have also confirmed that body fat will accelerate the process of telomere shortening. For the first time, the new study found that sodium in salt and fat are “wandering”, leading to a faster process of telomere shortening. This situation also occurs among young people. Therefore, when parents prepare food for their children, they should try to let their children eat more fresh fruits and vegetables, eat more low-salt foods, and eat more salty snacks such as potato chips.
