Nanoparticles in food packaging could be harmful to digestion

The video discusses oxide nanoparticles, focusing on their antimicrobial properties and the impact of zinc oxide nanoparticles on the human body. Binghamton researchers found that zinc oxide nanoparticles in the small intestine can exceed the recommended daily allowance by 100 times, leading to the remodeling or loss of microvilli and reduced nutrient absorption. High doses also trigger pro-inflammatory signaling, increasing intestinal permeability and allowing harmful compounds to enter the bloodstream.

What is one of the primary properties of oxide nanoparticles?

• Antimicrobial

• Radioactive

• Magnetic

• Conductive

What did researchers at Binghamton discover about zinc oxide nanoparticles?

• They are harmless in the small intestine.

• They exceed the recommended daily allowance by 100 times.

• They improve nutrient absorption.

• They have no effect on microvilli.

What effect do zinc oxide nanoparticles have on microvilli?

• They enhance microvilli growth.

• They cause remodeling or loss of microvilli.

• They have no impact on microvilli.

• They protect microvilli from damage.

What is a consequence of high doses of zinc oxide in the intestine?

• Decreased intestinal permeability

• Improved digestion

• Increased nutrient absorption

• Triggered pro-inflammatory signaling

How can increased intestinal permeability affect the body?

• It prevents harmful compounds from entering the bloodstream.

• It allows harmful compounds to pass into the bloodstream.

• It enhances the immune response.

• It reduces the risk of infections.
