Nutrition and Mental Health: What Foods Help with Depression?

Depression is a common mental health disorder that affects millions of people worldwide. While there are many treatment options available, including therapy and medication, nutrition also plays an important role in managing depression symptoms. Research has shown that certain foods and nutrients can help support mental health and improve mood. In this article, we’ll explore the link between nutrition and mental health, and focus on specific foods that can help with depression. By incorporating these foods into a balanced diet, you can take a proactive approach to managing your mental wellness.

Omega-3 Fatty Acids

Omega-3 fatty acids are a type of polyunsaturated fat that are found in foods like fatty fish, flaxseeds, and walnuts. These healthy fats play an important role in brain function and have been shown to have a positive impact on mental health, including depression.

Studies have found that people with depression often have lower levels of omega-3 fatty acids in their blood compared to those without depression. This suggests that omega-3s may play a role in regulating mood and reducing the risk of depression.

To incorporate more omega-3s into your diet, try adding fatty fish like salmon, mackerel, or sardines to your meals a few times per week. Plant-based sources of omega-3s include flaxseeds, chia seeds, and walnuts. You can also consider taking an omega-3 supplement, although it’s always best to talk to your doctor or a registered dietitian before adding any supplements to your routine.

Complex Carbohydrates

Carbohydrates are an important source of energy for our bodies and brains. While simple carbohydrates like sugar and white bread can cause blood sugar spikes and crashes, complex carbohydrates like whole grains, fruits, and vegetables provide a steady stream of energy and can help regulate mood.

Studies have found that people who eat a diet high in refined carbohydrates have an increased risk of depression, while those who eat a diet rich in whole foods and complex carbohydrates have a lower risk. This may be because complex carbohydrates contain important nutrients like B vitamins, which are important for brain health.

To incorporate more complex carbohydrates into your diet, try swapping out refined grains like white bread and pasta for whole grain options like whole wheat bread and quinoa. Add fruits and vegetables to your meals and snacks, and aim to fill half of your plate with non-starchy veggies like broccoli, peppers, and leafy greens.

Vitamin D

Vitamin D is an important nutrient that plays a role in many aspects of health, including bone health and immune function. It’s also been linked to mental health, with research suggesting that low levels of vitamin D may be linked to depression.

One study found that people with depression who took a vitamin D supplement for eight weeks experienced significant improvements in their symptoms compared to those who took a placebo. While more research is needed to fully understand the link between vitamin D and depression, it’s clear that this nutrient plays an important role in mental health.

The best source of vitamin D is sunlight, as our bodies can produce it when our skin is exposed to UV rays. However, many people don’t get enough sun exposure, especially during the winter months or if they live in northern latitudes. Good food sources of vitamin D include fatty fish like salmon and tuna, egg yolks, and fortified foods like milk and orange juice.

B Vitamins

B vitamins are a group of nutrients that are important for many functions in the body, including energy production and nervous system function. They’re also essential for brain health and have been linked to a lower risk of depression.

Studies have found that people with depression tend to have lower levels of certain B vitamins, including folate and vitamin B12. Low levels of these vitamins may affect neurotransmitter levels in the brain, which can lead to mood changes and depression.

Good food sources of B vitamins include leafy greens, whole grains, legumes, and animal products like meat and dairy. Some breakfast cereals and other foods are also fortified with B vitamins.

If you’re not getting enough B vitamins from your diet, supplements can be a good option. Talk to your healthcare provider to determine the best dosage and type of B vitamin supplement for you.


Antioxidants are compounds that protect cells from damage caused by harmful molecules called free radicals. Free radicals can damage cells and contribute to the development of many diseases, including mental health conditions like depression.

Studies have found that people with depression tend to have higher levels of oxidative stress, which occurs when there are too many free radicals in the body. Antioxidants can help combat this oxidative stress and protect cells from damage.

Good food sources of antioxidants include fruits and vegetables, especially those that are brightly colored, like berries, tomatoes, and leafy greens. Other sources of antioxidants include nuts, seeds, and dark chocolate.

If you’re not getting enough antioxidants from your diet, supplements can be a good option. However, it’s important to talk to your healthcare provider before starting any new supplement, as some can interact with medications or have other side effects.


Probiotics are beneficial bacteria that live in the gut and help support digestive health. However, research has also shown that they may have a positive effect on mental health.

Studies have found that taking probiotics can help improve symptoms of depression and anxiety. One theory is that the gut-brain axis, the communication network between the gut and the brain, plays a role in mental health. Probiotics may help improve the gut microbiome, which in turn could improve mental health.

Good food sources of probiotics include fermented foods like yogurt, kefir, kimchi, and sauerkraut. However, not all fermented foods contain probiotics, so it’s important to check the label.

If you’re not a fan of fermented foods, supplements are also available. Look for a high-quality probiotic supplement with multiple strains of bacteria and at least 10 billion colony-forming units (CFUs).

Caffeine and Sugar

While some foods can help improve mental health, others can have a negative effect. Caffeine and sugar are two culprits that can contribute to depression and anxiety.

Caffeine is a stimulant that can disrupt sleep and cause feelings of anxiety and irritability. It can also interfere with the absorption of some nutrients that are important for mental health, like magnesium.

Sugar, on the other hand, can cause rapid spikes and crashes in blood sugar levels, which can lead to mood swings and feelings of fatigue and depression.

While it’s not necessary to completely avoid caffeine and sugar, it’s important to consume them in moderation. Try to limit caffeine to no more than 400 milligrams per day, which is about the amount in four cups of coffee. For sugar, aim to limit added sugars to less than 10% of your daily calories.

Meal Planning

One of the best ways to ensure you’re getting the right nutrients to support mental health is through meal planning. Planning meals in advance can help you make sure you’re getting a variety of nutrient-dense foods, and can also help you avoid the temptation to reach for less healthy options when you’re short on time.

Start by taking an inventory of the foods you have on hand and making a list of the meals you want to make for the week. Try to include a variety of foods from different food groups, including lean proteins, complex carbohydrates, healthy fats, and plenty of fruits and vegetables.

When planning your meals, think about incorporating some of the foods we’ve discussed in this article, like fatty fish, leafy greens, whole grains, and probiotic-rich foods. You can also experiment with new recipes and ingredients to keep things interesting.

Once you’ve planned your meals, take some time to prep as much as you can in advance. This might mean chopping vegetables, cooking some grains or proteins, or making a big batch of soup or chili to have on hand for easy meals throughout the week.

By taking the time to plan and prep your meals, you’ll be setting yourself up for success when it comes to supporting your mental health through nutrition.


When it comes to supporting mental health, nutrition can play a powerful role. By incorporating foods rich in omega-3 fatty acids, complex carbohydrates, B vitamins, vitamin D, antioxidants, and probiotics into your diet, you can help support your mood, reduce inflammation, and promote healthy brain function.

It’s important to remember that nutrition is just one aspect of mental health, and that there are many other factors that can contribute to depression and anxiety. If you’re struggling with mental health issues, it’s important to seek help from a healthcare professional.

That being said, making small changes to your diet can be a great place to start when it comes to supporting your mental health. By incorporating some of the foods we’ve discussed in this article and being mindful of your caffeine and sugar intake, you can take a step towards a healthier, happier you.
