Farmers in Oregon, Washington, and Idaho have been using a plant called “eco-fiber” since the 1970s, and the plant has a long history of being used in agriculture.
But a new study says the fiber may actually be harmful to people, especially people with asthma.
The study, published in the Journal of the American Medical Association, examined the effects of using “eco fiber” in asthma patients.
The fibers have a special way of dissolving in the lungs, making it difficult to breathe normally.
“The fiber has a high degree of toxicity to the lung,” study author Mark B. Hausman told Reuters Health.
“The high dose of this toxin makes it more difficult for the patient to breathe.
In asthma, that is a major problem.”
The study involved 616 patients who were randomly assigned to take either fiber supplements, or a placebo.
The fiber supplements were labeled as “eco” and the placebo as “traditional.”
The researchers found that the patients who took the fiber supplements developed more asthma symptoms than those who took a placebo, with a 95 percent increase in asthma symptoms and a 14 percent increase compared to the placebo group.
The results of the study were similar for people who had chronic obstructive pulmonary disease, a disease that affects the lungs and has been linked to asthma.
Hauseman said that the findings may point to an underlying mechanism of the fiber’s toxicity.
The fibers also cause inflammation in the lining of the lungs.
“People who have asthma tend to have inflammation,” he said.
“That inflammation leads to inflammation in their lungs, which in turn leads to more inflammation in other organs.
So, if you have inflammation in your lungs, you’re more likely to have more asthma.”
The fibers may actually cause inflammation that leads to asthma, according to the study.
The fiber is used as an ingredient in the natural supplement Tumor, but it also can be used as a food supplement.
Hausman said the researchers will be analyzing how the fibers were used, as well as whether the fiber actually helps asthma patients live better.
“We’re looking at the impact on asthma, how the fiber affects the lung, how it interacts with the immune system, and how it affects the overall health of the person,” he told ReutersHealth.
“We’re going to look at how that affects their quality of life, as opposed to the people who are using the fiber as a supplement.”
The results are significant, said B.G. Hochschild, a professor of medicine at Duke University School of Medicine and a medical adviser for the Cochrane Collaboration.
“This is a big study that provides some interesting findings,” Hochloess said.
Hussein M. Salih, a clinical professor of pulmonary medicine at the University of Wisconsin, Milwaukee, agreed that the study provides new information.
“They’re going after something that’s been known for years,” he added.
“I would not have anticipated this result.”
A fiber supplement may actually have a negative effect on people with certain lung diseases, he said, noting that the fiber can be beneficial to people who have chronic obstructives and are taking asthma medications.
“There are studies that show that fiber supplements have some effect on lung function and that the risk of developing asthma increases with lung function,” he explained.
“There are other studies that suggest that the benefit of fiber supplements in asthma may not be the same as it is for asthma, and that there is some risk.”
Hausmann said he hopes the study helps explain the differences between the people in the study who had asthma and those who did not.
“For people who do not have asthma, the benefits of fiber supplementation are very, very clear,” he noted.
“It is not clear whether fiber supplements will improve asthma.
But we’re getting a lot of interesting information.”SOURCE: bit.ly/1Xqkq2m Journal of American Medical Admissions, online March 29, 2021.
