Adding extra salt to your food at the table associated with a greater risk of CVD, heart failure

Regularly adding a little more salt to your meals may be having a significant impact on your risk of developing cardiovascular disease (CVD) or heart failure, according to new research published in the Journal of the American College of Cardiology.[1]

The analysis focused on more than 176,000 participants from the UK Biobank study. All patients were free of CVD when the study began. A questionnaire was used to learn about each participant’s eating habits, including how often they shake a little extra salt onto their food before they eat it.

The group found that regularly adding more salt to your meals was associated with a higher risk of poor cardiovascular outcomes such as CVD, heart failure and ischemic heart disease.

“Overall, we found that people who don’t shake on a little additional salt to their foods very often had a much lower risk of heart disease events, regardless of lifestyle factors and pre-existing disease,” senior author Lu Qi, MD, PhD, a professor at the school of public health and tropical medicine at Tulane University in New Orleans, said in a prepared statement. “We also found that when patients combine a DASH diet with a low frequency of adding salt, they had the lowest heart disease risk. This is meaningful as reducing additional salt to food, not removing salt entirely, is an incredibly modifiable risk factor that we can hopefully encourage our patients to make without much sacrifice.”

Adding salt to foods less often was more likely when the person was a woman, white or had a lower body mass index. They were also more likely to already have high blood pressure or present with chronic kidney disease. In addition, they were more likely to adhere to a DASH-style diet and eat a higher amount of fruits, vegetables, legumes and whole grains, but less likely to drink sugar-sweetened drinks or eat red/processed meats.

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.
