Percentage of fast-food items (n = 222) that contained each salt substitute/enhancer and comparison of the proportion of foods that decreased (n = 140) and did not decrease (n = 82) in sodium per serving. Salt substitutes were identified using Appendix D in Strategies to Reduce Sodium Intake in the United States published by the Institute of Medicine.¹² *p < 0.001 for χ2 test comparing the association between the presence of a particular salt substitute/enhancer in a food and the likelihood that the sodium level (mg/serving) in that food decreased between 2010 and 2016.
