Salt Substitutes Lower Hypertension Risk in Older Adults
Updated June 15, 2025
Replacing regular salt with a salt substitute could considerably decrease the incidence of hypertension, or high blood pressure, among older adults. A study published in the Journal of the American College of cardiology found that salt substitutes did not elevate the risk of low blood pressure episodes.
The study revealed that individuals using a salt substitute experienced a 40% reduction in the likelihood of developing hypertension compared to those using regular salt. This is especially relevant given that the World Health Institution identifies hypertension as a leading contributor to cardiovascular disease and mortality,affecting over 1.4 billion adults and causing 10.8 million deaths annually.
One key strategy to combat hypertension is reducing sodium intake. This research explores salt substitutes as a more effective method for managing healthy blood pressure than simply cutting back on salt alone.
Yangfeng Wu, MD, PhD, lead author of the study and Executive Director of Peking University Clinical Research institute in Beijing, said adults often consume too much salt through processed foods. He emphasized the importance of recognizing the impact of dietary choices on heart health and increasing awareness of lower-sodium options.
The DECIDE-Salt study, conducted in China, involved 611 participants aged 55 and older from 48 care facilities. The facilities were divided into two groups: one replaced regular salt with a salt substitute (313 participants), while the other continued using regular salt (298 participants). Participants had blood pressure below 140/90 mmHg and were not on anti-hypertension medication at the start of the study. Researchers tracked the incidence of hypertension, initiation of anti-hypertension medications, and major cardiovascular events.
After two years, the hypertension rate was 11.7 per 100 people-years in the salt substitute group, compared to 24.3 per 100 people-years in the regular salt group. The study also found that salt substitutes did not cause hypotension, a common concern in older adults.
“Our results showcase an exciting breakthrough in maintaining blood pressure that offers a way for people to safeguard thier health and minimize the potential for cardiovascular risks,all while being able to enjoy the perks of adding flavorful flavor to their favorite meals,” Wu said.
Wu added that salt substitutes, with their proven blood pressure-lowering effects, could benefit both hypertensive and normotensive individuals, making them a desirable population strategy for preventing and controlling hypertension and cardiovascular disease.
Rik Olde Engberink, MD, PhD, from Amsterdam University Medical Center, noted the study offers an appealing alternative to reducing salt intake. He suggested salt substitutes should be adopted early in the food chain by the food industry to improve the sodium-potassium ratio of processed foods.
what’s next
Further research is needed to explore the long-term effects of salt substitutes and their broader request in the food industry to reduce hypertension rates globally.
