Can a common food preservative harm the immune system?

Various common chemicals may harm the system , causing it to malfunction. this is often referred to as immunotoxicityTrusted Source. These harmful effects could also be temporary or permanent.

Possible immunotoxic effects include:

-hypersensitivity
-chronic inflammation
-immunosuppression, or an impairment of the body’s ability to repel infections
-immunostimulation, which may cause tissue damage through immune responses
autoimmunity
-In particular, if an immunotoxic substance causes the body to supply fewer antibodies, it can have an impact on the fight against active infections and therefore the protection against future ones.

-The FDA currently require immunotoxicity testing for food additives. However, most food additives received approval decades ago, and therefore the FDA don’t mandate updated testing on previously approved additives.

TBHQ and PFAS
TBHQ may be a common preservative that manufacturers use to prolong their products’ shelf lives.

According to the Environmental working party (EWG), it’s present in almost 1,250 processed foods, including Cheez-It crackers, Pop-Tarts, Reese’s spread Cups, and tiny Debbie Swiss Rolls.

However, this chemical has had immunotoxic effects in animal studies.

Chemicals can also leach from packaging or food processing equipment into food. Some bags, boxes, and food wrappers are coated with per- and polyfluoroalkyl substances (PFAS).

PFAS-based materials also are common in non-stick coatings on cookware, gaskets in food processing equipment, and repeat-use plastics.

The FDATrusted Source require immunotoxicity testing just for food contact substances with a high daily exposure. The immunotoxicity of the many food additives and food contact substances is essentially unknown.

The Environmental Protection Agency (EPA) use high throughput in-vitro testing in their ToxCast program. this sort of testing exposes living cells, proteins, or biological molecules during a laboratory environment to chemicals to assess and identify any potential toxic effects. This potentially limits the necessity for animal testing.

The sparsity of current immunotoxicity data prompted the researchers from the EWG to conduct a study to guage the immunotoxic effects of common food additives and food contact substances. They also assessed the utility of ToxCast data in screening for immunotoxicity.

Lead study author Dr. Olga Naidenko, Ph.D., EWG’s vice chairman for science investigations, emphasizes the urgency of this research:

“The pandemic has focused public and scientific attention on environmental factors which will impact the system . Before the pandemic, chemicals which will harm the immune system’s defense against infection or cancer didn’t receive sufficient attention from public health agencies. to guard public health, this must change.”

The researchers analyzed a complete of 63 direct food additives present on quite 10 product labels sold within the U.S. in 2018–2020. They also specifically assessed nine identified PFAS that migrate from food packaging to food.

The findings now appear within the International Journal of Environmental Research and Public Health.

The study evaluated these substances, concentrating on those with the very best number of active ToxCast assays. It focused further analyses on those substances with activity toward multiple immune-related targets and proteins involved in immune reaction , inflammation, and defense mechanisms.

The study compared the results of high throughput ToxCast data with available data from animal and epidemiological studies.
