Anxiety is a common problem for many people. It’s a disorder characterized by constant worry and nervousness, and is sometimes related to poor brain health. Medication is often required as treatment.
Aside from medication, there are several strategies you can use to help reduce anxiety symptoms, from exercising to deep breathing.
Additionally, there are some foods you can eat that may help lower the severity of your symptoms, mostly due to their brain-boosting properties.
Here are 6 science-backed foods and beverages that may provide anxiety relief.
Salmon contains nutrients that promote brain health, including vitamin D and the omega-3 fatty acids eicosapentaenoic acid (EPA) and decosahexaenoic acid (DHA) ( 1Trusted Source, 2, 3Trusted Source, 4Trusted Source).
EPA and DHA may help regulate the neurotransmitters dopamine and serotonin, which can have calming and relaxing properties.
Additionally, studies show these fatty acids can reduce inflammation and prevent brain cell dysfunction that leads to the development of mental disorders like anxiety.
Consuming adequate amounts of EPA and DHA may also promote your brain’s ability to adapt to changes, allowing you to better handle stressors that trigger anxiety symptoms (5Trusted Source).
Even a few servings of salmon a week may be enough to promote anxiety relief.
In one study, men who ate Atlantic salmon three times per week for five months reported less anxiety than those who ate chicken, pork or beef.
Moreover, they had improved anxiety-related symptoms, such as heart rate and heart rate variability (8Trusted Source).
Chamomile is an herb that may help reduce anxiety. It contains high amounts of antioxidants proven to reduce inflammation, which might decrease the risk of anxiety (9Trusted Source, 10Trusted Source, 11Trusted Source).
Several studies have examined the association between chamomile and anxiety relief.
They have found that those diagnosed with generalized anxiety disorder (GAD) experienced a significantly greater reduction in symptoms after consuming chamomile extract, compared to those who did not (12Trusted Source, 13Trusted Source).
Another study found similar results, as those who consumed chamomile extract for eight weeks saw reduced symptoms of depression and anxiety (14Trusted Source).
While these results are promising, most studies have been conducted on chamomile extract.
More research is necessary to evaluate the anti-anxiety effects of chamomile tea, which is most commonly consumed.
Animal and test-tube studies suggest that curcumin may boost the omega-3 fatty acid DHA in the brain by helping your body synthesize it more efficiently (15Trusted Source).
In one study, 20 mg/kg of curcumin produced significant anti-anxiety effects in stressed mice compared to those given a lower dose (17Trusted Source).
Curcumin also has powerful antioxidant and anti-inflammatory properties that have been shown to prevent damage to brain cells (9Trusted Source, 16Trusted Source, 18Trusted Source, 19Trusted Source, 20Trusted Source, 21Trusted Source, 22Trusted Source).
These effects are partly due to curcumin’s ability to reduce inflammatory markers, such as cytokines, which are often linked with anxiety development (9Trusted Source, 16Trusted Source, 23Trusted Source).
More human research is needed to confirm all of these effects, but if you suffer from anxiety, incorporating turmeric into your diet is certainly worth a try.
- Dark Chocolate
Incorporating some dark chocolate into your diet may also be helpful for easing anxiety.
Dark chocolate contains flavonols, which are antioxidants that may benefit brain function.
These effects may allow you to adjust better to the stressful situations that can lead to anxiety and other mood disorders.
Some researchers also suggest that dark chocolate’s role in brain health may simply be due to its taste, which can be comforting for those with mood disorders (26Trusted Source).
In one study, individuals who consumed 74% dark chocolate twice daily for two weeks had improved levels of stress hormones commonly associated with anxiety, such as catecholamines and cortisol (27Trusted Source).
Eating dark chocolate has also been shown to increase levels of the neurotransmitter serotonin, which may help reduce the stress that leads to anxiety (25Trusted Source, 28Trusted Source, 29Trusted Source, 30Trusted Source).
For example, in a study of highly stressed individuals, participants reported significantly lower levels of stress after consuming 40 grams of dark chocolate every day over a two-week period (28Trusted Source).
However, dark chocolate is best consumed in moderation, as it is high in calories and easy to overeat. 1–1.5 ounces is a reasonable serving size.
If you suffer from anxiety, yogurt is a great food to include in your diet.
Studies have shown that probiotic foods like yogurt may promote mental health and brain function by inhibiting free radicals and neurotoxins, which can damage nerve tissue in the brain and lead to anxiety (33Trusted Source, 34Trusted Source).
In one study, anxious individuals who consumed probiotic yogurt daily were better able to cope with stress than those who consumed yogurt without probiotics (35Trusted Source).
Another study found that women who consumed 4.4 ounces (125 grams) of yogurt twice daily for four weeks had better functioning of the brain regions that control emotion and sensation, which may be associated with lower anxiety levels (36Trusted Source).
These findings are promising, but more human research is necessary to confirm the beneficial effects that yogurt may have on anxiety reduction.
It is also important to note that not all yogurt contains probiotics. For the benefits of probiotics, choose a yogurt that has live active cultures listed as an ingredient.
- Green Tea
In one small study, people who consumed L-theanine experienced a reduction in psychological stress responses that are commonly associated with anxiety, such as increased heart rate (40Trusted Source).
Another study found that those who drank a beverage that contained L-theanine had decreased levels of cortisol, a stress hormone linked with anxiety (41Trusted Source).
These effects may be due to L-theanine’s potential to prevent nerves from becoming overexcited.
Moreover, green tea contains epigallocatechin gallate (EGCG), an antioxidant suggested to promote brain health.
It may play a role in reducing certain symptoms by also increasing GABA in the brain (42Trusted Source).
One mouse study found that EGCG produced anti-anxiety effects similar to those of common anxiety medications (43Trusted Source).
The beneficial properties of L-theanine and EGCG may be a major reason why drinking several cups of green tea daily is associated with less psychological distress (44Trusted Source).
While all of these findings are promising, it is worth mentioning that most of the research on green tea and anxiety has been conducted in animals and test tubes.
More human research is needed to confirm its anti-anxiety effects.
Other Foods That May Help With Anxiety
While some of the foods listed below have not been studied specifically for their anti-anxiety effects, they are rich in nutrients thought to improve related symptoms.
- Turkey, bananas and oats: These are good sources of the amino acid tryptophan, which is converted to serotonin in the body and may promote relaxation and anxiety relief (45Trusted Source, 46Trusted Source, 47Trusted Source).
- Eggs, meat and dairy products: All provide high-quality protein including essential amino acids that produce the neurotransmitters dopamine and serotonin, which have the potential to improve mental health (11Trusted Source, 48Trusted Source, 49Trusted Source, 50Trusted Source).
- Chia seeds: Chia seeds are another good source of brain-boosting omega-3 fatty acids, which have been shown to help with anxiety (11Trusted Source, 51, 52Trusted Source).
- Citrus fruits and bell peppers: These fruits are rich in vitamin C, which has antioxidant properties that may help reduce inflammation and prevent damage to cells that may promote anxiety (11Trusted Source, 21Trusted Source, 53, 54).
- Almonds: Almonds provide a significant amount of vitamin E, which has been studied for its role in anxiety prevention (11Trusted Source, 55).
- Blueberries: Blueberries are high in vitamin C and other antioxidants, such as flavonoids, that have been studied for their ability to improve brain health and thus help with anxiety relief (21Trusted Source, 56, 57Trusted Source, 58Trusted Source).
Overall, research is sparse on the topic of specific foods and anxiety prevention.
Most studies have been conducted on animals or in laboratories, and more high-quality human studies are needed.
However, there are several foods and beverages that may help you deal with your anxiety symptoms, as they may reduce inflammation and boost brain health.
