Landmark study shows simple salt swap could prevent millions of deaths each year

Changing desk salt with a reduced-sodium, added-potassium ‘salt substitute’ considerably reduces charges of stroke, coronary heart assault and dying, in response to the outcomes of one of many largest dietary intervention research ever carried out.

Offered at a ‘hotline session’ on the European Society of Cardiology Congress in Paris on August 29, and concurrently printed within the New England Journal of Drugs, the outcomes additionally confirmed that there have been no dangerous results from the salt substitute.

Excessive ranges of sodium consumption and low ranges of potassium consumption are widespread, and each are linked to hypertension and larger dangers of stroke, coronary heart illness and untimely dying. Utilizing a salt substitute—the place a part of the sodium chloride is changed with potassium chloride—addresses each issues without delay. Salt substitutes are recognized to decrease blood stress however their results on coronary heart illness, stroke, and dying have been unclear, till now.

Lead investigator, Professor Bruce Neal of The George Institute for World Well being, stated that the size of the profit seen within the examine might stop hundreds of thousands of early deaths if salt substitutes have been broadly adopted.

“Virtually everybody on the earth eats extra salt than they need to. Switching to a salt substitute is one thing that everybody might do if salt substitutes have been on the grocery store cabinets,”‘ he stated.

‘”Higher nonetheless, whereas salt substitutes are a bit dearer than common salt, they’re nonetheless very low-cost—just some {dollars} a yr to make the change.”

“In addition to exhibiting clear advantages for essential well being outcomes, our examine additionally allays considerations about doable dangers. We noticed no indication of any hurt from the added potassium within the salt substitute. Definitely, sufferers with severe kidney illness shouldn’t use salt substitutes, however they should avoid common salt as effectively,” added Professor Neal.

The Salt Substitute and Stroke Research enrolled 21,000 adults with both a historical past of stroke or poorly managed blood stress from 600 villages in rural areas of 5 provinces in China—Hebei, Liaoning, Ningxia, Shanxi and Shaanxi between April 2014 and January 2015.

Contributors in intervention villages have been offered sufficient salt substitute to cowl all family cooking and meals preservation necessities—about 20g per individual per day—free-of-charge. These within the different villages continued utilizing common salt.

Throughout a mean comply with up of virtually 5 years, greater than 3,000 individuals had a stroke. For these utilizing the salt substitute, researchers discovered that stroke danger was decreased by 14 p.c, whole cardiovascular occasions (strokes and coronary heart assaults mixed) by 13 p.c and untimely dying by 12 p.c.

Professor Neal stated that as a result of salt substitutes are comparatively low-cost (about US$1.62 per kilo versus US$1.08 per kilo for normal salt in China) they’re prone to be very value efficient too.

‘”Final yr, a modeling examine completed for China steered that about 400,000 untimely deaths may be prevented annually by nationwide uptake of salt substitute. Our outcomes now affirm this. If salt was switched for salt substitute worldwide, there can be a number of million untimely deaths prevented yearly,” he stated.

“That is fairly merely the one most worthwhile piece of analysis I’ve ever been concerned with. Switching desk salt to salt substitute is a extremely possible and low-cost alternative to have a large international well being profit.”

On account of the examine, George Institute researchers are calling for the next actions:

• Salt producers and retailers worldwide ought to change to producing and advertising and marketing salt substitute at scale
• Governments worldwide ought to design polices to advertise salt substitute and discourage common salt use
• Customers worldwide ought to cook dinner, season and protect meals with salt substitute not common salt
