We recommend paying attention to the amount of a nutrient (such as how many mg of sodium) instead of percent, as the standards that these percents are based on are not appropriate for all patients. Percentages can indicate if something is "high" or "low" in sodium, but I would more often educate someone on a maximum number of mg to look for, as everyone's goal or limit is different. A common cardiac guideline is to limit sodium to no more than 200 mg per serving, or no more than 600 mg per meal. I hope this helps!
