Health experts recommend that most people eat no more than 2,300 milligrams of salt a day, the equivalent of 1 teaspoon. But children and adults alike are consuming, on average, about 3,400 milligrams daily, according to the study.
The study authors found that when young people increased their daily salt levels by 1,000 milligrams, the risk for high blood pressure increased 74% for overweight or obese youngsters, but only 6% for kids in the normal weight range. The researchers looked at more than 6,200 young people, ages 8 to 18. More than a third were overweight or obese and 15% had elevated or high blood pressure.
Most of the salt we consume is already in the foods we eat, not what we add at the dinner table.
Breads and rolls, cold cuts, pizza, fresh and processed poultry, soups, sandwiches, cheese, pasta dishes, meat dishes and snacks are the top 10 food sources that account for 44% of sodium consumed, according a report released by the Centers for Disease Control and Prevention in February.
"If you have high blood pressure in childhood, it's likely that the effects will last into adulthood. Increased blood pressure is one of the most significant risk factors for cardiovascular disease (heart disease)," explains lead study author Quanhe Yang, who works with the Division for Heart Disease and Stroke Prevention at the Centers for Disease Control and Prevention.
