A Centers for Disease Control and Prevention study in the United States has identified bread and dinner rolls as the main source of salt in the country

According to the reports, the average consumption of salt in the country is 3,266 milligrams per day which is 42 percent more than the recommended limit of 2,300 milligrams.
Stating that the increased consumption of salt has led to increased risk of high blood pressure, CDC director Dr Thomas Frieden said, “One of the things that is driving blood pressure up is that most adults in this country eat or drink about twice the amount of sodium as is recommended. Most of that extra sodium comes from common grocery store and restaurant items and a very small proportion from the salt shaker at the table.”
