Food packaging could be negatively affecting the way in which your digestive tract operates, according to new research by faculty and students at Binghamton University, State University at New York.
"We found that zinc oxide (ZnO) nanoparticles at doses that are relevant to what you might normally eat in a meal or a day can change the way that your intestine absorbs nutrients or your intestinal cell gene and protein expression," said Gretchen Mahler, associate professor of bioengineering.

According to Mahler, these ZnO nanoparticles are present in the lining of certain canned goods for their antimicrobial properties and to prevent staining of sulfur-producing foods. In the study, canned corn, tuna, asparagus and chicken were studied using mass spectrometry to estimate how many particles might be transferred to the food. It was found that the food contained 100 times the daily dietary allowance of zinc. Mahler then looked at the effect the particles had on the digestive tract.

"People have looked at the effects of nanoparticles on intestinal cells before, but they tend to work with really high doses and look for obvious toxicity, like cell death," said Mahler. "We are looking at cell function, which is a much more subtle effect, and looking at nanoparticle doses that are closer to what you might really be exposed to."
"They tend to settle onto the cells representing the gastrointestinal tract and cause remodeling or loss of the microvilli, which are tiny projections on the surface of the intestinal absorptive cells that help to increase the surface area available for absorption," said Mahler. "This loss of surface area tends to result in a decrease in nutrient absorption. Some of the nanoparticles also cause pro-inflammatory signaling at high doses, and this can increase the permeability of the intestinal model.

An increase in intestinal permeability is not a good thing—it means that compounds that are not supposed to pass through into the bloodstream might be able to."

Although Mahler studied these effects in the lab, she said she is unsure what the long-term health implications might be.
"It is difficult to say what the long-term effects of nanoparticle ingestion are on human health, especially based on results from a cell culture model," said Mahler. "What I can say is that our model shows that the nanoparticles do have effects on our in vitro model, and that understanding how they affect gut function is an important area of study for consumer safety."

The researchers are looking at how an animal model (chickens) responds to nanoparticle ingestion.
"We have seen that our cell culture results are similar to results found in animals and that the gut microbial populations are affected. Future work will focus on these food additive-gut microbiome interactions," said Mahler.

it's true ,though

he's wrong, there are plenty of studies that show how light goes through glass and plastic to fuck up food

Could be worse, could be Calcium.

Yes there are other studies about food and packaging. Why does water in a plastic bottle have an expiration date? The plastic leaches into the bottle. Oh leave the water bottle in your hot car in the sun, it most likely leaches more and faster.

This why you gotta take the food out of the packaging before eating it.

Brilliant! I've been eating whole tuna cans all this time! Thank you Anon, truly you are a lifesaver!

>>244505
actual studies that are INCONCLUSIVE, are not the same as fearmongering by NRA or rightwingers doing the bidding of multinaitonals and hedge funds.

cause those bottles are biodegradable

thank god I can steal high quality glass bottled water from work,
