Salt

In a new study researchers have found salt consumption may speed up aging. The earlier said health risks associated to it are high blood pressure, kidney disorder and osteoporosis.

The new study comes from researchers of Medical College of Georgia and presented to the American Heart Association’s 2014 Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions in San Francisco. The team discovered the protective caps on the end of chromosomes are shorter in obese and overweight teenagers who consume more salt than others.

Earlier research says the protective chromosome ends, also called as telomeres, becomes shorter as one gets old and this is accelerated by high body fat, lack of physical activity and smoking.

For the new study researchers examined more than 700 people aged between 14 and 18 years. The teenagers were divided into high intake of salt and low intake of the same. It was found the overweight or obese teens who consumed more sodium were with shorter telomeres compared to those who consumed less sodium.

Researchers also found the obesity is linked to high levels of inflammation, which again hastens shortening of telomere.

It is suggested lowering sodium intake should be first preferred than losing weight in overweight teens.

Lead author Haidong Zhu said, “In a new study researchers have found salt consumption may speed up aging. The earlier said health risks associated to it are high blood pressure, kidney disorder and osteoporosis.

Zhu is a medical doctor and also assistant professor of pediatrics at the medical college.
