Most health experts believe that excessive intake of salt is harmful to health, specifically in increasing blood pressure, increasing the risk of heart disease and stroke. A team of the US Centers for Disease Control and Prevention found that dietary “more salt and less potassium†is more unhealthy and increases the risk of death.
Researchers published a paper in the new issue of Internal Medicine that they started with data from the United States on health census and analyzed the links between sodium and potassium intake and mortality rates of more than 12,000 people over 15 years. The results showed that excessive intake of salt will increase the risk of death due to multiple diseases by 20%, while increased potassium intake can reduce the risk of death by 20%.
They also found that the "high-salt and low-potassium" dietary structure with a high sodium-potassium ratio is the most dangerous. The highest proportion of sodium and potassium diet in the diet compared with the lowest sodium and potassium diet, the risk of death was 46% higher, in particular, the risk of death from coronary heart disease was more than doubled.
Dr. Elena Cooklina, who participated in the study, said that the sodium in table salt will increase blood pressure, and potassium will have the effect of lowering blood pressure. It should also pay attention to the balance between potassium and salt. She said that the “more potassium and less sodium†diet is more healthy and more fruits, vegetables and low-fat dairy products should be added to the diet.
For this discovery, the parties have different opinions. Dr. Thomas Farley and others from the New York City Department of Health and Mental Health commented in the same issue of the Internal Medicine literature that previous investigations have found a relationship between high salt and low potassium diets and hypertension and cardiovascular disease. Discovery provided strong evidence to support it. The United States Salt Industry Organization does not approve.
The World Health Organization recommends that adults eat no more than 5 grams of salt per day, that Americans eat twice as much salt, and that about 90% of Americans have excessive sodium intake. The restaurant's dishes and deep-processed foods sold in stores are generally high in sodium.
