7 Key Concepts
Nutritional Psychiatry
This field uses healthy whole foods and nutrients to enhance mental well-being. It is designed to work synergistically with other treatments like therapy and medication, not to replace them entirely.
Gut-Brain Connection
This refers to the communication system between the gut and the brain, which originate from the same embryonic cells and remain connected by the vagus nerve. Chemical messages are exchanged, influencing both physical and mental states.
Food-Mood Connection
This concept explains how the foods we eat impact our mood, primarily through their interaction with the gut microbiome. Healthy foods promote beneficial breakdown products and reduce inflammation, while unhealthy foods can lead to dysbiosis and inflammation, affecting brain health.
Gut Microbiome
This refers to the trillions of microbes and their genetic material living in the gut. These microbes interact with digested food, producing either beneficial short-chain fatty acids or more toxic breakdown products, which in turn affect gut and brain inflammation.
Orthorexia
This is an unhealthy obsession with healthy eating, where individuals become fixated on certain foods and dietary rules. Nutritional psychiatry aims to avoid this by focusing on including more healthy foods and making sustainable, flexible changes rather than extreme exclusions.
Intuitive Eating
This approach encourages individuals to eat what they want, when they want, and in the portions they desire, while listening to their body's hunger cues and maintaining a gentle understanding of nutrition. It emphasizes balance and flexibility over strict dietary rules.
Dysbiosis
This term describes an imbalance in the gut microbiome, often caused by consuming unhealthy foods. It leads to inflammation in the gut, which can then extend to the brain, contributing to mental health conditions like depression and anxiety.
7 Questions Answered
Nutritional psychiatry uses healthy whole foods and nutrients to improve mental well-being, working alongside traditional treatments like therapy and medication.
Food impacts your brain and mood through the gut-brain connection; healthy foods promote beneficial gut microbes and reduce inflammation, while unhealthy foods can cause an imbalance in the gut microbiome and lead to inflammation in the brain.
The science behind nutritional psychiatry is robust regarding the gut microbiome, but it is still a nascent and evolving field, providing guidance for healthier eating patterns rather than diagnostic approaches.
Psychiatric medications can be life-saving for severe illnesses, but nutritional psychiatry suggests that lifestyle and food choices can be powerful tools to either stave off medication use or work synergistically with it, especially given potential side effects and the tendency for quick prescriptions in the medical system.
Vitamins are a type of supplement, but 'supplements' is a broader category that includes various substances like saffron or ashwagandha. Supplements are not as regulated as prescription medications, making it important to discuss their use with a clinician.
To avoid orthorexia, focus on including more healthy foods and widening options rather than fixating on exclusions or extreme diets. The goal is to make slow, steady, and sustainable changes, allowing for flexibility and balance (e.g., an 80-20 rule).
Key anxiety-triggering foods include artificial sweeteners, refined and added sugars, processed foods containing industrialized seed oils, fast foods (which are pro-inflammatory), and trans fats.
