Diet and depression are linked, and understanding this connection can help in managing symptoms. There are many benefits to a healthy lifestyle, and one of them is its positive impact on mental health. Your brain functions at its best when it’s fueled with healthy, nutrient-dense foods.

However, a good diet is just one part of an overall mental health care plan. If you’re dealing with depression, a whole-person treatment plan including therapy and potentially medication, can also be incredibly beneficial.

How Diet Impacts Mental Health

Several scientific studies highlight the importance of diet on mental health. Those who eat a varied diet full of vegetables, fruits, whole grains, and legumes tend to have a lower risk of developing mental health concerns like depression and anxiety. Diets full of vegetables, fruits, legumes, and whole grains can reduce inflammation while boosting the vitamins and minerals our brains need to thrive.¹

Inflammation

Inflammation occurs when the body’s immune system releases chemicals in response to pathogens or injuries. This natural process helps fight off infections, but when it becomes chronic, it can lead to a wide range of health problems, including depression.²

Certain foods, like refined sugars and processed meats, can increase inflammation, while others, like fruits and vegetables, have anti-inflammatory properties.

Vitamins & Brain Health

Your brain needs certain vitamins and minerals to function properly, like B and D vitamins, magnesium, and omega-3 fatty acids. These vitamins are involved in the production, transmission, and synthesis of important neurotransmitters like serotonin and norepinephrine, which are responsible for mood.³

The Gut Microbiome

The gut-brain connection is a growing area of research, and evidence suggests that a healthy gut microbiome can positively impact mental health. Eating foods rich in probiotics, like yogurt and kimchi, can promote good gut health.²

How Food & Depression Can Cause a Spiral

Studies have shown that people who eat a healthy diet are at a lower risk for developing depression, and at the same time, being depressed can make it more difficult to do so. When depressed, people often reach for fast food and other snacks high in sugar and fat.

While perfectly fine in moderation, if one’s diet consists of mostly refined foods and a lack of vegetables, fruits, whole grains, and lean proteins, this means that they probably aren’t getting those important vitamins and minerals that boost brain health. Plus, those highly processed foods can spike inflammation levels.

Foods That May Help with Depression

While there’s no specific “depression diet,” there are certain foods that may have mood-boosting benefits. Many studies have shown that diets that are high in vegetables, whole grains, legumes, and some healthy fats and lean meats, like the Mediterranean diet, can be a protective factor against depressive symptoms.

These foods have been investigated as positively impacting depression symptoms:

• Antioxidants: Foods rich in antioxidants are anti-inflammatory and promote brain health, and include berries, broccoli, spinach, carrots, and potatoes
• Protein: Lean proteins like fish, chicken, and legumes can boost your energy levels and keep the mind clear.
• Selenium: Selenium promotes serotonin and dopamine in the brain and protects against inflammation. Foods rich in selenium include beans and legumes, lean meats, nuts and seeds, and whole grains.
• Omega-3 fatty acids: Found in fatty fish like salmon, mackerel, and tuna, as well as in plant-based sources like flaxseeds and chia seeds, omega-3s have been found to have anti-inflammatory effects and may help reduce symptoms of depression.
• Complex carbohydrates: Whole grains, legumes, and starchy vegetables like sweet potatoes are complex carbs that release energy slowly and can help stabilize blood sugar levels. This can keep mood swings and energy dips at bay.
• Dark leafy greens: Leafy greens like kale, spinach, and collard greens are rich in folate, a B vitamin that has been linked to better mental health. They also contain magnesium, which has been found to have a calming effect on the brain.

However, don’t be afraid to incorporate the foods you love into your diet. All foods can fit into a balanced, healthy eating plan, and depriving yourself of your favorite treats can actually make you feel worse. Moderation is key, and it’s better to think about adding healthy foods to your diet, not restricting what you eat.

Tips for Making Healthy Dietary Changes for Depression

If you’re dealing with depression, it can be hard to just get off the couch, let alone make a healthy meal. However, even just a few small steps toward adding in more nutrients to your diet can make a big difference. There’s no shame in buying the “convenience” version if that means you’ll actually eat it, such as pre-cut veggies or healthy frozen meals.

Here are a few tips for incorporating more nutrient-rich foods into your diet if you’re dealing with depression:

• Start a food mood diary: Starting to notice which foods make you feel worse versus which give you an energy boost can be a great place to start when considering how your diet is currently impacting your mood.
• Add (or eliminate) one thing at a time: If you’re depressed, you’re likely already overwhelmed. Try thinking through small shifts you can make, like snacking on fruit in the evenings or swapping your chips for carrots at lunch. Small changes can add up over time.
• Keep healthy snacks on hand: Take the guesswork out of snack time by keeping healthy snacks easy to access. This could be pre-peeled hardboiled eggs in the fridge, individual bags of nuts, or pre-sliced fruits and veggies.
• Try eating mindfully: Instead of eating while watching TV or scrolling social media, try slowing down and enjoying your meals.
• Focus on consistency vs perfection: The point of shifting your diet is to add more nutrients into your body, not to hit some level of “perfection.” Think about what you’re consistently adding, and don’t beat yourself up on days when all you can do is eat some chicken nuggets. Fed is still best.
• Schedule a checkup: Talk to your doctor about your symptoms and any physical changes you’ve noticed. They may request some bloodwork, as several factors can contribute to both physical and mental symptoms. For example, a vitamin D deficiency could be diagnosed, which contributes to mood and energy levels.
• Talk to a registered dietitian or nutritionist: For individualized tips and plans, even just a couple of meetings with a dietitian or nutritionist could be incredibly helpful. They can assist you in thinking through what you can actually stick to.

Diet Should Be Part of a Comprehensive Care Plan for Depression

In the end, while the foods you put in your body can have a big impact on your mental health, if you’re dealing with depression you shouldn’t expect to “fix” it just by shifting your diet. If you’ve experienced low mood, irritability, changes to sleep or diet, or feelings of hopelessness for more than a couple of weeks, you should reach out for professional depression treatment.

A therapist can help you untangle your thoughts and feelings, and develop new coping skills for dealing with depression symptoms. For some, medication may be a necessary part of healing as well. Working with an empathetic care team can make a big difference in how you feel.
