6 Foods That Trigger Anxiety, From A Nutritional Psychiatrist

While stress is a normal and healthy reaction to challenges throughout life (we call this good stress eustress), it can become dangerous when it's chronic or excessive. 

My field of nutritional psychiatry addresses the symptoms of anxiety through evidence-based food choices. It operates on the idea that the foods we eat play a key role in reducing or exacerbating anxiety via the gut-brain connection. 

The gut-brain connection highlights the interconnectivity of these two organs, indicating that the gut and the brain are in constant two-way communication and the health of one directly influences the health of the other. Our gut microbes, specifically, are a key determinant of anxiety symptoms. When inflammation is present in the gut, it can lead to inflammation in the brain called neuroinflammation. Evidence tells us that neuroinflammation is increased in those with anxiety1, so those looking to reduce symptoms of stress should avoid anxiety-inducing foods.

Packaged foods that we find on grocery store shelves with lengthy ingredient lists and expiration dates are typically packed with processed additives like sugar and omega-6 fatty acids. When consumed in excess, these ingredients feed the bad microbes in the gut and worsen inflammation2 (and, therefore, stress) over time. These foods are also devoid of brain-boosting vitamins, minerals, and fiber.

Did you know that there are about 262 other names for the sneaky sugars found in food items today? While you expect these to be found in cakes, pastries and baked goods, boxed cereals, and granola bars, you don't think of the sugar in ketchup, salad dressings, or pasta sauces. Sugars can even be found in more savory items like takeout french fries.

The hyper-palatability of these foods may initially please taste buds, but excess sugar ultimately wreaks havoc on gut health, exacerbates inflammation, increases anxiety3, and worsens mood4.

The industrialization of the food industry has led to the development of highly processed, inexpensive oils. These oils are typically created from the byproduct of the system's most abundantly grown crops (such as corn, grapeseed, soybean, sunflower, and palm fruit). Through processing, these oils become high in omega-6 fatty acids and devoid of omega-3s. Excess omega-6 fatty acids in the diet contribute to an excess of inflammatory molecules5 throughout the body, especially in the gut and brain.

One of my pillars of nutritional psychiatry is to follow your body's intelligence regarding anxiety-inducing foods.

This is important because each person's microbiome is unique, so no two people react to foods exactly the same. Therefore, foods that induce anxiety for some may not have such stressful effects on others. While the above foods are all linked to inflammation of the gut and brain, the extent to which individuals will experience symptoms vary. So I encourage people to be mindful when it comes to eating, acknowledge how different foods make them feel, and then choose accordingly.
