Sandwiches boost daily sodium intake
A majority of Americans include sandwiches in their daily diet, but most don't realize that sandwiches today, with their mulitple ingredients, have the potential to carry a considerably higher level of sodium than in the past., according to new research.
A study published in the Journal of the Academy of Nutrition and Dietetics has found that on any given day, 49 percent of American adults eat at least one sandwich, and sandwiches can provide between 20 and 50 percent of the daily recommended intake.
The researchers analyzed data from a 2009-2010 survey in which 5,762 adults over the age of 20 recorded everything they ate and drank the previous day. The scientists analyzed the data by assigning each food and beverage with one or more codes so nutritional value could be assessed. They concluded that by replacing higher-sodium ingredients with lower-sodium ones, a person could significantly reduce their sodium intake.
They also found that those who ate a sandwich on the survey day consumed about 300 more calories, and they also had higher total sodium intakes per day - around 600 mg more than those who did not eat a sandwich.
High sodium levels have been linked to high blood pressure, which can lead to strokes and heart disease.
