Recently, longevity entrepreneur Bryan Johnson revealed that he has autoimmune gastritis. In this condition, the immune system attacks the stomach’s own parietal cells—the cells responsible for producing hydrochloric acid and intrinsic factor, a protein essential for vitamin B12 absorption. As the damage progresses, stomach acid falls (hypochlorhydria), vitamin B12 deficiency may develop, and digestion becomes increasingly impaired. Immunologists explain this as a loss of imm

The mouth does not exist in isolation. It is connected to the rest of the body through the immune system, circulation, hormones, metabolism, and inflammation.

Because these compounds are extremely resistant to breakdown, they accumulate in the environment and in the human body.
