"You are what you eat". I know you have heard this phrase, as it has been around for centuries. Though how we treat symptoms of the gut has been updated more recently. In the 19th century it was believed that one can suffer from auto-intoxication. Auto-intoxication was believed to be the result of poisons emanating from the gut. These poisons cause infections that were linked to depression, anxiety, and even psychosis.
2016 has brought some scientific evidence that pulls us right back to the 1800's without the horrific scientific procedures (thank goodness). Scientists are now more than convinced that the vast assemblage of macrofauna in our intestines may have a major impact on our state of mind. It is more profound than they originally thought. The brain and gut are bidirectional in the communication. The brain acts on gastrointestinal and immune functions that assist to form the gut's microbial makeup and gut microbes make neuroactive compounds including neurotransmitters and metabolites that also act on the brain. Bidirectional communication can occur in many ways, here are three of them.
- Via the vagus nerve the microbial compounds are communicable, connecting the brain and digestive tract.
- Microbially derived metabolites interact with the immune system, maintaining it's own communication with the brain.
- A brilliant scientist, Svn Patterson, has shown that gut microbes help control leakage through both the intestinal lining and the blood-brain barrier.
The scientists are finding many links to human disorders and your gut. Disorders such as autism, depression, anxiety stress, ADD, ADHD. Today you can easily participate in an unsolicited study of probiotics in your yogurt and daily vitamins.
Have a great day and enjoy your yogurt.
