Research suggests that various nutritional deficiencies, such as zinc and vitamin B, are present in people with mental health conditions like OCD. Here are foods that can help.

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent, intrusive, and unwanted thoughts, known as obsessions. OCD is also characterized by repetitive, ritualized behaviors, also known as compulsions.

Some experts believe that the foods we eat can help manage symptoms of OCD.

If you’re looking for natural options to treat your OCD, you may consider giving your diet a second look to ensure you take in the best foods and supplements for you.

According to the National Alliance on Mental Illness, the recommended treatment for OCD includes cognitive behavioral therapy (CBT) and medication.

But certain medicines can cause unpleasant side effects that may lead you to look at other forms of treatment, such as dietary supplements. Below are foods you may consider to help manage your symptoms.

Foods high in vitamin D

A much-needed vitamin, your body takes in vitamin D through some foods, supplements, and even the sunlight. It helps with many bodily functions, including:

  • absorbing calcium in our belly and bones
  • bone growth
  • preventing osteoporosis
  • reducing inflammation
  • aiding in cell growth and metabolism
  • improving immunity

Foods that serve as sources of the vitamin include:

  • fish, like trout and salmon
  • beef liver
  • eggs
  • cheese
  • mushrooms
  • milk
  • soy milk
  • oat milk
  • cereal

According to a 2020 review, while there is limited data, research suggests there is a negative correlation between vitamin D and OCD symptoms.

More clinical trials are needed to see if vitamin D supplementation can improve OCD symptoms. Consider speaking with a medical professional to help you decide if vitamin D best suits your needs.

Foods high in vitamin B12

While more research is needed, studies suggest a pattern between vitamin B12 deficiencies and OCD. They also recommend that doctors evaluate each person with OCD for a possible deficit, since it can affect brain function.

Your body needs B12 to aid in its central nervous system function (brain and nerves), formation of healthy red blood cells, and creating and maintaining its DNA.

If you’re looking to add more to your diet, here are some foods high in B12:

  • beef liver
  • clams
  • tuna
  • salmon
  • beef
  • milk
  • yogurt

Foods high in zinc

Zinc is an essential nutrient needed for brain development and aids in digestion, among other things.

People with OCD deal with issues related to their brain’s ability to adapt and change in response to their experiences and environments. But a small 2012 clinical trial suggests that when zinc is taken with fluoxetine it can improve OCD symptoms.

Foods that serve as good sources of zinc include:

  • oysters
  • beef
  • crab
  • lobster
  • pork
  • beans

Foods high in antioxidants

Antioxidants could be a promising alternative treatment for OCD. Research suggests that oxidative stress contributes to your OCD symptoms.

By taking in antioxidants, you help improve anti-inflammatory and antioxidant activities inside your body, thus leading to better brain health.

According to a 2010 study, plant-based foods have significantly more antioxidants than nonplant foods. Foods high in antioxidants include:

  • dark chocolate
  • pecans
  • blueberries
  • strawberries
  • artichokes
  • raspberries
  • kale
  • red cabbage

According to a 2017 study, experts believe that inflammation in your brain can play a role in OCD. So, you may find it helpful to avoid foods that cause inflammation and additional stress on your body.

Foods high in sugar

According to a 2018 literature review of several studies, sugar contributes to your inflammatory processes. To help reduce the chance of inflammation, consider enjoying the following foods in moderation:

  • candies and desserts
  • sugar-sweetened drinks
  • baked goods
  • foods containing high fructose corn syrup
  • honey and syrups

According to the American Heart Association, it’s recommended that you limit excess sugar intake.

They suggest that most American women take in no more than six teaspoons of sugar daily, and no more than nine teaspoons for most American men.

In a large 2021 study, findings indicate that fried meat affects the gut microbiota. This impacts the balance of glucose in your body, and increases inflammation and toxins.

Other foods to consider eating in moderation include refined carbohydrates and red processed meats.

Your mental health is an integral part of your overall health and well-being.

Habits such as eating a well-balanced diet, exercising regularly, and getting an adequate amount of sleep can help you cope with your symptoms.

Regular check-ups with your doctor are also crucial to maintaining a good bill of health.

If you currently take medication prescribed by your doctor to manage your OCD symptoms, consider speaking with them to discover how you can incorporate alternative treatments in support of your medicine.

If you plan on discontinuing your medication it can be helpful to discuss this with your doctor to develop a plan that will best support you.

A note on accessibility

In 2016, as many as 40.6 million Americans lived in poverty, many of whom experienced food insecurity. Despite food stamp programs like the Supplemental Nutrition Assistance Program (SNAP), not everyone can always afford to eat healthily.

Many people don’t have access to fresh and nutritious foods because they may live in food deserts or food swamps, where dollar and liquor stores might be the only options for buying foods and drinks.

If some of the healthier food options suggested in this article are inaccessible to you, know that it’s not your fault.

Remember that frozen and canned foods, such as frozen fruits and veggies or canned fish, can be healthy options too.

It’s also important to keep in mind that dietary changes are not the only self-care strategy you can try to boost your serotonin levels. If you want to learn about other things you can do, consider reading this article.

Therapy may also be a viable option, but if you’re unsure of how to afford it, these tips and free resources may get you started.
