The results showed that in general, people consumed more sodium throughout the day than the USDA guidelines recommend: an average of 3,900 mg of sodium for sandwich eaters and 3,200 mg for those who didn’t have a sandwich.
This was true for both men and women and across all age groups, the researchers report in the Journal of the Academy of Nutrition and Dietetics.
But the biggest spread was apparent between men who ate sandwiches, who averaged up to 4,800 mg of sodium in a day, and men who didn’t eat them and averaged just under 3,900 mg.
Men in general ate significantly more sandwiches and took in almost twice as much sodium from sandwiches as women did, Sebastian told Reuters Health in an email.
