Individuals without knowing make poor food choices and select foods that might actually contribute to depression or worsen. There has been evidence that suggests a link between low levels of serotonin and suicide. Low serotonin levels are often attributed to anxiety, depression, panic attacks, insomnia, obesity, fibromyalgia, eating disorders, chronic pain, migraines, and alcohol abuse.
The function and production of the neurotransmitters like serotonin is highly influenced by the billions of “good” bacteria that make up a person’s intestinal microbiome, which is the genetic material of all the microbes bacteria, fungi, protozoa, and viruses that live on and inside the human body (Hair, Sharpe, 2014). These bacteria play an essential role in a person’s health because they protect the lining of a person’s intestines and ensure they provide a strong barrier against toxins and “bad” bacteria. It limits inflammation and improves how well a person absorb nutrients from their food. They activate neural pathways that travel directly between the gut and the brain (Selhub, 2015).
