The Link Between Anxiety & Your Food Choices

Have you heard the news? A panel of medical experts recently announced that all adults under the age of 65 should consider getting screened for anxiety. The statement stems from concern that Americans as a whole have been experiencing stressors from all angles over the past few years, resulting in a growing number of mental health concerns. Despite some lingering stigma, new studies continue to show how important mental health is, and how it affects our lives on a day-to-day basis. The good news is, there are plenty of lifestyle changes you can make to help. Today, we are going to talk about changes you can make to your diet, and the science between nutrition, and your mental state.

 

Explaining Anxiety

Anxiety comes in MANY flavors. From Agoraphobia and specific Phobia’s to Obsessive Compulsive Disorder, there are many different conditions that can fall under the umbrella of anxiety. Some forms are more obstructive to everyday life than others, and each person may experience different intensities of these disorders depending on a number of factors. The most common form of anxiety is Generalized Anxiety Disorder, which is what we will primarily focus on in this article.

Generalized Anxiety disorder happens when there is an imbalance between your brains Prefrontal Cortex (the part of your brain responsible for cognitive control functions and decision making) and the Amygdala (the part of your brain linked to processing emotions and memories associated with fear or threats). Under normal circumstances, your Prefrontal Cortex regulates your Amygdala and is able to manage any threat responses that may be stimulated. However, the Amygdala of a person with Anxiety often goes unchecked, and the Amygdala may generate stress or fear signals even without an obvious physical threat.

Essentially what this leads to is a consistent feeling of fear or unease. Symptoms of this kind of Anxiety can include elevated heart rate, flushed skin, tense muscles, inability to concentrate or focus, irritability, insomnia, and general fatigue.

 

Anxiety, Neurotransmitters, and Your Second Brain

Second brain? Yes, you read that right. Believe it or not, your gut is embedded with some 100 million neurons (more than what makes up your spinal cord or peripheral nervous system) and is technically called the Enteric nervous system. Although this ‘second brain’ plays zero part in any cognitive functions, it does play a vital role in our mental state and combatting a number of diseases throughout the body (no surprise there).

This system sends and receives signals from the brain, and secretes neurotransmitters identical to those found in the central nervous system (eg, acetylcholine, dopamine, and serotonin). These neurotransmitters are the key connection between your diet, your gut, and your mental health. Studies have shown that there is a correlation between your gut’s microbiome, and it’s secretion of these neurotransmitters.

Low levels of serotonin specifically have been linked to higher levels of anxiety and depression. For example, many anxiety and depression prescriptions work by blocking the reuptake of serotonin so more of it remains in circulation throughout your body. Going back to what we said about the Brain, higher serotonin levels help the prefrontal cortex communicate and regulate the threat responses of the amygdala.

So to sum it up, a healthy gut = a healthy gut microbiome = healthy levels of important neurotransmitters = healthy communication in the brain = reduced chances of unnecessary or unregulated fear responses = reduced anxiety and anxiety symptoms.

 

That’s great, but how does our diet help?

So we’ve determined that our gut health is really important, and the best way to keep our guts healthy is to eat a wide variety of nutrient-dense whole foods. Specifically, look for food with the following:

  • Fiber – Helps the body slow down the absorption of glucose, which prevents spikes in blood sugar levels and avoids sugar crashes.
  • Antioxidants – Helps to prevent inflammation in the gut and throughout the body.
  • Folate – Promotes production of the neurotransmitter Dopamine.
  • Vitamin D – Promotes production of the neurotransmitter Serotonin.
  • Magnesium – Promotes healthy protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation.
  • Fermented foods – The superfood of gut health, fermented foods are packed with probiotics, or healthy gut bacteria, that are essential to a healthy gut microbiome.

 

Foods that make Anxiety worse.

Although these foods don’t CAUSE anxiety, the effect they have on our bodies may mimic symptoms and make your existing anxiety feel even worse.

  • Processed food, and sugary drinks – an obvious culprit, as processed foods are usually lacking good fiber and nutrient density, while also being high in sugar, bad fats, and sodium. This leads to spikes in blood sugar levels and crashes where you feel fatigued more easily. They also provide very little, if any, nutritional benefits to your gut.
  • Caffeine – Often used as a stimulant to help people feel more awake, alert, or energetic, caffeine’s effects can quickly get out of hand and cause you to feel jittery, and irritable, and can increase your heart rate to uncomfortable levels.
  • Alcohol – Sometimes used as a way to cope with anxiety, alcohol’s long-term negative effects on the body can be serious, and often cause imbalances in bodily systems and sleep patterns.

 

Quick disclaimer:

As we stated at the beginning of this post, anxiety comes in MANY different shapes and sizes. And although we’ve explored how your food choices can help, it’s important to recognize that these lifestyle changes may not be enough in some circumstances, and we encourage you to talk to your doctor if your anxiety is disrupting your everyday life. Mental health is important, and we believe it should always be taken seriously.
