“Broadly speaking, the vagus nerve is always associated with the parasympathetic nervous system and has an inhibitory influence upon the heart and sympathetic nervous system activity. Most importantly, Porges’ research identified that the parasympathetic nervous system has two presentations that depend upon whether you feel safe or feel threatened. In times of safety, the parasympathetic nervous system facilitates rest, relaxation, and digestion. However, in times of threat the parasympathetic nervous system has a defensive mode…”   Source: Polyvagal theory unlocks symptoms of PTSD | Dr. Arielle Schwartz Recommend on Facebook Tweet about it

NIEHS postdoctoral researcher and lead author Kristen Upson, Ph.D., offered a potential explanation for the association between soy formula and severe menstrual pain. She said that data from previous laboratory animal studies suggest that early-life exposure to genistein, a naturally occurring component in soy formula, interferes with the development of the reproductive system, including factors involved in menstrual pain. She said these studies have also shown that developmental changes can continue into adulthood.   However, severe menstrual pain is not the only adverse reproductive health condition that Upson has linked to infant soy formula. She and her collaborators at the Fred Hutchinson Cancer Research CenterRead More →

Salt samples from 21 countries in Europe, North and South America, Africa, and Asia were analyzed. The three brands that did not contain microplastics are from Taiwan (refined sea salt), China (refined rock salt), and France (unrefined sea salt produced by solar evaporation). The study was published this month in the journal Environmental Science & Technology. Source: Microplastics found in 90 percent of table salt: potential health impacts?
