A new book, "Gut Check," set to release on January 9, 2024, delves into the complex and intriguing world of gut health, exploring how microorganisms influence our physiology and behaviors.

One fascinating subject in the book is the parasite toxoplasmosis, known for its effect on mammalian behavior. Pregnant women are advised to avoid cats due to the risk of toxoplasmosis, which can adversely affect their unborn children.

Toxoplasmosis uses rodents as an intermediate host to reach its final host—cats. It alters the rodent's brain, affecting the fear and reward centers, making them drawn to cat-related threats.

In various species, such as chimpanzees, wolves, and even humans, toxoplasmosis can reduce natural fears, influencing behavior in significant ways.

The book discusses Neu5Gc, a sugar molecule present in certain animal products, which our immune systems can mistakenly identify as foreign, promoting inflammation.

Recent research shows that Neu5Gc is integrated into bodily structures, prompting an immune response that could underlie multiple health issues.

"Gut Check" highlights leaky gut, confirmed by modern testing, and its established connection to autoimmune diseases. The book discusses how lifestyle changes can significantly remedy these issues.

Tests confirm that leaky gut is prevalent in all patients with autoimmune conditions. Encouraging dietary protocols can substantially improve intestinal barrier integrity and reduce associated health markers.

Although Dr. Gundry provides a sneak preview of these complex health topics, details and solutions will be deeply explored in "Gut Check," intended to arm readers with knowledge for better health choices.
