Chemicals that can make you feel good but could also cause serious health problems may be making their rounds in your food.
The synthetic fibers made from genetically modified plants are often called “fiber” and have been linked to health issues like asthma, obesity, and cancer.
Now, scientists are looking at the health effects of using synthetic fibers in foods like bread, cookies, and pasta.
While some studies have shown some health benefits of the synthetic fibers, some scientists are concerned that the synthetic fiber could pose health risks to consumers.
“It has to be treated with caution, because there’s been no scientific research that really looks at the long-term effects,” said Katherine R. Stahl, an associate professor of environmental health sciences at the University of North Carolina, who is also a lead author of a study published in the journal Environmental Health Perspectives.
In her study, Stahl and her colleagues evaluated synthetic fibers that had been produced by using synthetic genes from bacteria to make polystyrene.
They found that the fibers made in this way were “probably not harmful to consumers” and could help make bread and pasta more nutritious.
The study found that people who ate a lot of these synthetic fibers had lower levels of body fat and less insulin sensitivity than people who were not exposed to the synthetic polystyrenes.
“There are no good and bad consequences associated with the use of these fibers,” Stahl said.
“They’re just making more products and there are no health risks associated with it.”
Some scientists are worried that the use a synthetic fiber might be harmful to people who eat it.
“I’m not going to say they’re bad for us, but we need to be aware of what’s going on in our bodies,” Stahls said.
If you’ve ever eaten bread, you know the fiber can make it seem like it’s made of gluten or flour.
“We eat wheat and other grains for a reason,” Staisels said.
But Stahl believes that there’s no reason to worry about a synthetic polysaccharide or polyethylene.
“The synthetic fibers don’t seem to pose any adverse health effects to humans,” Stuhls said, “and the long term effects of exposure to them are very small.”
The synthetic polyester fiber is used in a variety of products, from cooking oil to paper to plastics.
“This is just a very basic polymer, and it’s just a small percentage of the total polyester fibers in the world,” Stichls said in an interview.
“But it’s not like we can’t find any other types of polymers that can be used in these products.”
Stahl also said that she believes that synthetic fibers could pose a health risk for some people.
“People may have higher rates of chronic diseases that they’re genetically predisposed to,” she said.
This could be a concern for people with a family history of certain types of cancer, such as lung cancer.
She also said she is concerned that synthetic polymers might be “bad for the environment.”
Synthetic fibers were originally developed for use in the manufacturing of paper and plastics.
But scientists are now developing other products using the synthetic materials, such a polyvinyl alcohol that can help make paints, and even other synthetic fibers.
In the past, synthetic fibers were found in some products that had to be cleaned and dried before they could be used.
But some of these cleaning products can be toxic.
“When you’re cleaning your home with cleaning products, you can get some chemicals in there that you wouldn’t expect to be there,” Sthl said.
Stahl said that the study is just one step in a bigger investigation.
The FDA has issued guidelines that require chemical companies to study the health impacts of the chemicals they use in their products and report back to the agency on how to reduce the exposure of consumers to chemicals.
“You want to make sure that the health concerns are addressed before you start using them in your products,” Stoll said.
The research was conducted by Stahl’s group at the Icahn School of Medicine at Mount Sinai in New York, and was funded by the National Institutes of Health (NIH) and the National Science Foundation.
