THIS RESEARCH has confused many nutritionists as it also contradicts the statement of American Medical Association, American Health Association and Center for Disease Control and Prevention, which states that higher consumption of sodium increases the risk of heart diseases.
The study was done on 3,681 healthy European men and women below the age of sixty, for about eight years. The sodium levels in the urine were checked for the individuals, in the beginning and at the end of study. The participants were divided into three groups, the first group consumed low amount of salt, the second group consumed moderate amount of salt and the last group used higher amount of salt.
The result showed that, there were 50 deaths in the first group, which consumed low salt, 24 deaths in the moderate consumption group and 10 deaths in the high consumption group. The research concluded that heart disease risk in low consumption group was 56 percent higher than the high consumption group.
The scientists don't have the accurate explanation of the results, but they say that low levels of salt in body can affect the nervous system, lower the sensitivity towards insulin, and affect the blood pressure, which can cause heart diseases.
Some experts contest the study, saying that the participants used for the study were whites, young enough and reasonably healthy with normal blood pressure and the other study says that black people with hypertension and at an older age, react negatively on eating more salt, reported the Daily Mail.
The optimal level of the salts in our diets has been a subject of contradiction from past 20 years and till now there is no answer, because salt consumption does not have the same affect on everyone.
