New Warning from Researchers; Eating Fatty Foods May Lead to Increased Anxiety

A new study shows that a high-fat diet may affect brain chemicals through a complex process and increase anxiety. Many people tend to eat heavy, fatty foods when they feel anxious in order to achieve calmness. Researchers at the University of Colorado Boulder say this behavior may have the opposite effect. The researchers reached their recent findings after nine weeks of research on two groups of laboratory mice, with results published in the journal 'Biological Research.' Hundreds of species of bacteria live in the large intestine. According to the researchers, consuming a fatty food can disrupt the gut microbiome and disturb the balance and behavior of resident gut bacteria. Based on this new research, the disrupted microbiome in the gut damages its inner lining, allowing bacteria to enter the bloodstream and communicate with the brain via the 'vagus nerve.' As a result of this communication, the functioning of three genes involved in the production and signaling of 'serotonin' is altered. These three genes are associated with anxiety phenomena. Dr. Christopher Lowry, the lead author of the recent study, states that some subsets of serotonin neurons, when activated, may lead to reactions including anxiety in animals. Additionally, an increase in one of the enzymes of these genes, called 'tryptophan hydroxylase 2,' can have consequences in humans, including 'behavioral disorders and suicidal tendencies.' According to Dr. Lowry, it has been known that fatty foods are unhealthy, but it was thought that the worst consequence of such foods was 'weight gain.' He says that now, with the understanding that fatty foods can also increase anxiety, the risks of such foods can be considered even more seriously. Dr. Christopher Lowry suggests that individuals consume more fruits and vegetables and add fermented foods to their diet to maintain a healthy gut microbiome. This researcher from the University of Colorado also advises against eating pizza and fried potatoes and suggests that if one is to eat a hamburger, it is better to consume a slice of avocado alongside it. On the other hand, healthy fats are very beneficial for the body, especially for the brain, and can combat the 'negative effects of unhealthy fats.' Natural fats and oils from fish, olive oil, and nuts are among the beneficial fats.
