Summary of recommendations on sodium reduction in guidelines.

Guideline	Sodium reduction	Class of recommendation and level of evidence
2017 ACC [10]	Sodium reduction is recommended for adults with elevated BP or hypertension. Optimal goal is <1500 mg/d, but aim for at least a 1000 mg/d reduction in most adults	I A
2018 ESC [11]	Salt restriction to <5 g per day is recommended	I A
2019 NICE [12]	Encourage people to keep their dietary sodium intake low, either by reducing or substituting sodium salt, as this can reduce blood pressure	NA
2020 CAN [13]	To prevent hypertension and reduce BP in hypertensive adults, consider reducing sodium intake toward 2000 mg (5 g of salt or 87 mmol of sodium) per day	Grade A
2020 ISH [14]	Reduce salt added when preparing foods, and at the table. Avoid or limit consumption of high-salt foods such as soy sauce, fast foods, and processed food including breads and cereals high in salt	NA
