Nutrition and Mental Health

A variety of healthy foods arranged on a pink background, including bananas, blueberries, avocado, salmon, eggs, walnuts, broccoli, and a jar of tea, with a chalk drawing of a brain in the center.

We are so grateful to present a special blog post written by Tucson local Sarah Bodey, FNTP.

Food for Thought: How Nutrition Shapes Mental Health

More and more research is showing what we eat and digest affects all aspects of our life including mental health. We have known this since at least the 1960s when the ketogenic diet was used with schizophrenic patients and they experienced fewer symptoms.

But it doesn’t take a scientist to realize this — spend any time with a child that has eaten a ton of candy and you will quickly see a decrease in their ability to control their emotions. Not that mental illness is in any way comparable to a child that has had too much candy.

Now can diet heal your mental illness?

No, but it can be a valuable modality to add to any treatment plan.


Junk Food and Inflammation

We all know that eating chips and cookies or Ultra Processed Foods is not good for our health. I mean there is a reason they are called junk food.

These foods cause inflammation not only in our digestive system, but also in our brain.

  • In the digestive system, inflammation can present itself as intestinal pain, constipation, bloating, or diarrhea.
  • In the brain, inflammation can look like brain fog, anxiety or depression.

How Gut Inflammation Affects the Brain

So how does gut inflammation lead to issues in the brain?

Our intestines are a long tube, a single cell layer in thickness. These cells are held tightly together and only allow selected things to pass through into the body.

When the gut becomes inflamed, these tight junctions open and allow anything to enter our body. This could be:

  • Microbes
  • Large food particles
  • Toxins

More and more research is coming out that chronic inflammation is linked to different neurological disorders such as:

  • Autism
  • Depression
  • Anxiety
  • Schizophrenia

Repairing the tight junctions reduces inflammation which in turn can help to lessen symptoms.

Illustration comparing normal tight junctions in the intestine with leaky junctions, showing how harmful substances can leak into the bloodstream.

The Role of the Microbiome

Chronic inflammation changes the composition of the gut microbiome where over 60% of our serotonin is made. Serotonin is one of our “happy” hormones.

The gut microbiome produces many of our neurotransmitters, and by changing the make-up of this microbiome, we see an increase in our neurotransmitters and therefore mood.


Finding Support

The good news is you do not need to figure out your best diet, repair the tight junctions in your intestines or improve the microbiome on your own.

I am Sarah Bodey, a Functional Nutritional Therapy Practitioner (FNTP), and founder of SB Nutritional Foundations.


As an FNTP, I:

  • Evaluate not only your diet, but also how well you are digesting and absorbing those nutrients
  • Look at the quality of your sleep and stress
  • Use an extensive questionnaire and initial interview to determine which systems of your body need support
  • Identify which nutrients may be lacking in your diet
  • Consider your lifestyle and ability to prepare meals when building a plan

Together, we come up with a plan, help guide and support our clients towards better health, giving the body the nutrients and space it needs to repair.

Important note: An FNTP cannot cure or heal, but we can support the body in coming into balance and help relieve symptoms.


Final Thought

If you are on medication and in therapy but still experiencing symptoms, diet and lifestyle could be the missing piece in your treatment plan.
