Washington dc: People tend to report more gastrointestinal disturbances when they consume a diet rich in salt, the recent results suggest. Scientists again analyzed the data from a large clinical trial: the dietary approach to stop the sodium hypertension trial (DASH-Sodium), which was carried out two decades ago and found that a high Sodium consumption increased swelling among the participants in the trial. The researchers also discovered that the high fiber DASH diet increased the swelling among trial participants compared to a low fiber control diet.
The study was published in the American Journal of Gastroenterology. "Swelling is one of the main gastrointestinal complaints in the U.S. and it can be exacerbated in some people through a diet rich in fiber; our results suggest that they could reduce this swelling without compromising on healthy fiber, reducing the intake of Sodium, "he said, is studying the main author Noel Mueller.
It is estimated that swelling affects up to one third of American adults in general and more than 90% of irritable bowel syndrome. The swelling presents an accumulation of excess gas to the intestine. The production of gases can be attributed to intestinal bacteria producing gases that break down the fiber.
There is also evidence that sodium can stimulate swelling. According to the researchers, the study is the first to examine sodium as a cause of swelling in the context of low and high fiber diets.
The study analyzed data from the DASH-Sodium trial, conducted in four clinical centers during the period 1998-99, and tested the DASH diet, a diet rich in fiber that is relatively low in fats and in fruits, fruits nuts and vegetables, against low fiber control diet.
Each of the two diets was tested at three levels of sodium and the 412 participants had high blood pressure at the beginning of the trial. The trial was mainly established to determine the effect of dietary sodium and other blood pressure factors, but included data from participants' reports on swelling that Mueller and his colleagues analyzed for the new study
The team found that, before the trial, 36.7% of the participants reported swelling, which is more or less in line with the national surveys on the prevalence of swelling. They also discovered that the high fiber DASH diet increased the risk of inflation by around 41%, compared to the low fiber content diet, and men were more susceptible to this effect in comparison with women
But scientists also determined that sodium was a swelling factor. When data on DASH and control diets were combined and compared the highest level of sodium intake to the lowest, they found that the high sodium versions of these diets increased collectively the risk of Inflammation around 27% compared to low sodium. versions.
The key implication is that sodium reduction can be an effective way to reduce swelling – and, in particular, it can help people maintain a healthy and high fiber diet.
