Anxiety is a widespread condition, affecting millions of people globally. Symptoms vary, and some people only experience them now and then. However, someone who experiences symptoms for 6 months or longer may have a generalized anxiety disorder (GAD).
The symptoms of GAD include psychological and physical symptoms, such as:
- excessive worry about everyday events and problems
- difficulty concentrating
- issues with their personal social and work relationships
- heart palpitations, elevated heart rate
- muscle tension
- chest tightness
Doctors often treat GAD with a combination of treatments, including talking therapies, such as cognitive behavioral therapy (CBT), alongside medications. Sometimes, these conventional treatments do not work long-term. However, some research suggests that proper nutrition can help improve symptoms.
Nine foods to eat to help reduce anxiety
1. Brazil nuts
Brazil nuts are high in selenium. Selenium may improve mood by reducing inflammation, which is often at heightened levels when someone has a mood disorder, such as anxiety.
Selenium is also an antioxidant, which helps prevent cell damage. It is also anti-carcinogenic, which helps to prevent cancer from developing.
Other nuts, animal products, and vegetables, such as mushrooms and soybeans, are an excellent source of selenium.
It is important not to consume too much selenium as it can cause side effects. The recommended upper limit for selenium for an adult is 400 micrograms (mcg) per day. So be careful not to take supplements with high doses or eat more than a three to four Brazil nuts a day.
Brazil nuts and other nuts are also a good source of vitamin E. Vitamin E is an antioxidant. Antioxidants can be beneficial for treating anxiety, while some research has shown that low levels of vitamin E may lead to depression in some people.
2. Fatty fish
Fatty fish, such as salmon, mackerel, sardines, trout, and herring, are high in omega-3. Omega-3 is a fatty acid that has a strong relationship with cognitive function as well as mental health.
However, recent research has shown that if a person eats too much of another fatty acid, called omega-6, and not enough omega-3, they may increase their risk of developing mood disorders, such as anxiety.
Omega-3-rich foods that contain alpha-linolenic acid (ALA) provides two essential fatty acids: eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
EPA and DHA regulate neurotransmitters, reduce inflammation, and promote healthy brain function.
A small study on 24 people with substance abuse problems found that EPA and DHA supplementation resulted in reduced levels of anxiety. However, more research is required.
Current recommendations suggest eating at least two servings of fatty fish a week. A studyconducted on men found eating salmon three times a week reduced self-reported anxiety.
Salmon and sardines are also among the few foods that contain vitamin D.
Researchers are increasingly linking vitamin D deficiency to mood disorders, such as depression and anxiety. A report in the Journal of Affective Disorders believes that there is enough evidence to prove that vitamin D positively helps depression. Other studies on pregnant women and older adults have also highlighted how vitamin D might improve mood. Vitamin D may also improve seasonal disaffected disorder (SAD) during winter.
Egg yolks are another great source of vitamin D.
Eggs are also an excellent source of protein. It is a complete protein, meaning it contains all the essential amino acids the body needs for growth and development.
Eggs also contain tryptophan, which is an amino acid that helps create serotonin. Serotonin is a chemical neurotransmitter that helps to regulate mood, sleep, memory, and behavior. Serotonin is also thought to improve brain function and relieve anxiety.
4. Pumpkin seeds
Pumpkin seeds are an excellent source of potassium, which helps regulate electrolyte balance and manage blood pressure.
Eating potassium-rich foods such, as pumpkin seeds or bananas, may help reduce symptoms of stress and anxiety.
Pumpkin seeds are also a good source of the mineral zinc. One study carried out on 100 female high school students found that zinc deficiency may negatively affect mood.
Zinc is essential for brain and nerve development. The largest storage sites of zinc in the body are in the brain regions involved with emotions.
5. Dark chocolate
Researchers have found that dark chocolate may help reduce stress.
Experts have long suspected that dark chocolate might help reduce stress and anxiety. A 2014 study found that 40g of dark chocolate helped reduce perceived stress in female students.
Other studies have generally found that dark chocolate or cocoa may improve mood. However, many of these studies are observational, so the results need to be interpreted with caution.
Although it is still unclear how dark chocolate reduces stress, it is a rich source of polyphenols, especially flavonoids. One study suggested that flavonoids might reduce neuroinflammation and cell death in the brain as well as improve blood flow.
Chocolate has a high tryptophan content, which the body uses to turn into mood-enhancing neurotransmitters, such as serotonin in the brain.
Dark chocolate is also a good source of magnesium. Eating a diet with enough magnesium in it or taking supplements may reduce symptoms of depression.
When choosing dark chocolate, aim for 70 percent or more. Dark chocolate still contains added sugars and fats, so a small serving of 1 to 3 grams (g) is appropriate.
Turmeric is a spice commonly used in Indian and South-East Asian cooking. The active ingredient in turmeric is called curcumin. Curcumin may help lower anxiety by reducing inflammation and oxidative stress that often increase in people experiencing mood disorders, such as anxiety and depression. A 2015 study found that curcumin reduced anxiety in obese adults.
Another study found that an increase of curcumin in the diet also increased DHA and reduced anxiety. Turmeric is easy to add to meals. It has minimal flavor, so goes well in smoothies, curries, and casserole dishes.
