Common Food Additives May Promote Anxiety and Reduce Social Behavior: Mouse Study

P80 ice creamNote: I scream! You scream!

This study uses a mouse model - the results are thought provoking to say the least. We have seen a huge increase in anxiety especially in children and teenagers. GI issues are also on the rise. And those of us in the autism community are painfully aware of gut issues in our children. Polysorbate 80 is  also an ingredient in many infant vaccinations. That, however, is not mentioned in this article. This month, Dr. Paul Offit co-authored the following and just look what he says about P80 below. Is he admitting that in food doses P80 does cause harm? And how exactly does he know that vaccine injected dosages are safe? Gut instinct?

From the Children's of Philly Vaccine Education Center:

Stabilizers are used in vaccines to protect the integrity of the active ingredients during manufacture, storage and transport. A commonly used stabilizer that can be associated with allergic responses to vaccines is gelatin.

The HPV vaccine contains polysorbate 80 as a stabilizer. Some stories on the internet have suggested that polysorbate 80 in this vaccine causes infertility. First, it is important to know that the HPV vaccine does not cause infertility. Second, polysorbate 80 has been used for many years as an emulsifier to make ice cream smooth and to slow melting. A typical serving of ice cream (1/2 cup) may contain about 170,000 micrograms* of polysorbate 80. On the other hand, the amount of polysorbate 80 in each dose of the HPV vaccine — 50 micrograms* — is very small. Therefore, polysorbate 80 isn’t contained in vaccines at quantities that could possibly do harm.

Summary: A new mouse study reveals common food additives, such as the dietary emulsifiers CMC and P80, may increase the risk of anxiety related disorders and adversely affect social behaviors.

Source: Georgia State University.

Food additives known as dietary emulsifiers, commonly found in processed foods to improve texture and extend shelf life, may adversely affect anxiety-related and social behaviors in mice, Georgia State researchers have found.

The scientists also observed sex differences in the mice’s behavioral patterns, suggesting that emulsifiers affect the brain via distinct mechanisms in males and females.

The study, published in Scientific Reports, was led by Geert de Vries, professor of neuroscience and associate vice president for research at Georgia State, and Benoit Chassaing, assistant professor of neuroscience. Andrew T. Gewirtz, professor in the Institute for Biomedical Sciences, also contributed.

Previous research by Chassaing and Gewirtz has shown that emulsifiers can cause low-grade intestinal inflammation by altering the composition of gut microbiota, a diverse population of trillions of microorganisms that are vital to health. Their research has linked emulsifier consumption to obesity, metabolic syndrome and inflammatory bowel diseases such as colitis, conditions whose incidence has significantly increased since the mid-20thcentury.

In the same period there has also been an increased incidence of behavioral disorders such as autism, leading scientists to theorize that brain function may be affected by environmental exposure to modern chemical substances as well.

“We asked the question: Can emulsifiers’ effects on general systemic inflammation also be extended to the brain and to behavior?” de Vries said. “The answer was yes.”

The researchers added one of two commonly used emulsifiers, polysorbate 80 and carboxymethylcellulose, to the drinking water of male and female mice. After 12 weeks, they observed that treatment with emulsifiers altered the gut microbiota of males and females in different ways. They then conducted tests to assess the effects of the emulsifiers on behavior. The researchers found that emulsifiers altered anxiety-like behavior in male mice and reduced social behavior in female mice.

Sooooo, it is not genetic but environmental then.

Finally the game begins of "lets start looking. "

Dr. PrOffit appears not to know the difference between "stabilizer" and "emulsifier." Must have been asleep at that lecture. The GSU study is important work, an ominous finding. Alters the gut microbiota, and not for the better. Mice and humans share many of the bacterial species in the gut.
