9 Healthy Foods That Lift Your Mood
Thus, you may wonder whether any healthy foods can improve your mood.
Recently, research on the relationship between nutrition and mental health has been emerging. Yet, it's important to note that mood can be influenced by many factors, such as stress, environment, poor sleep, genetics, mood disorders, and nutritional deficiencies.
Nonetheless, certain foods have been shown to improve overall brain health and certain types of mood disorders.
Here are 9 healthy foods that may boost your mood.
1. Fatty Fish
Omega-3 fatty acids are a group of essential fats that you must obtain through your diet because your body can't produce them on its own.
Fatty fish like salmon and albacore tuna are rich in two types of omega-3s — docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) — that are linked to lower levels of depression.
Omega-3s contribute to the fluidity of your brain's cell membrane and appear to play key roles in brain development and cell signaling.
While research is mixed, one review of clinical trials showed that in some studies, consuming omega-3's in the form of fish oil lower depression scores.
Although there's no standard dose, most experts agree that most adults should get at least 250–500 mg of combined EPA and DHA per day.
Given that a 3.5-ounce (100-gram) serving of salmon provides 2,260 mg of EPA and DHA, eating this fish a few times per week is a great way to get these fats into your diet.
Fatty fish like salmon are rich in omega-3 fatty acids, which may lower your risk of depression.
2. Dark Chocolate
Chocolate is rich in many mood-boosting compounds.
Its sugar may improve mood since it's a quick source of fuel for your brain.
Furthermore, it may release a cascade of feel-good compounds, such as caffeine, theobromine, and N-acylethanolamine — a substance chemically similar to cannabinoids that has been linked to improved mood.
However, some experts debate whether chocolate contains enough of these compounds to trigger a psychological response.
Regardless, it's high in health-promoting flavonoids, which have been shown to increase blood flow to your brain, reduce inflammation, and boost brain health, all of which may support mood regulation.
Finally, chocolate has a high hedonic rating, meaning that its pleasurable taste, texture, and smell may also promote good mood.
Because milk chocolate contains added ingredients like sugar and fat, it's best to opt for dark chocolate — which is higher in flavonoids and lower in added sugar. You should still stick to 1–2 small squares (of 70% or more cocoa solids) at a time since it's a high calorie food.
Dark chocolate is rich in compounds that may increase feel-good chemicals in your brain.
3. Fermented Foods
Fermented foods, which include kimchi, yogurt, kefir, kombucha, and sauerkraut, may improve gut health and mood.
During this process, probiotics are created. These live microorganisms support the growth of healthy bacteria in your gut and may increase serotonin levels.
It's important to note that not all fermented foods are significant sources of probiotics, such as in the case of beer, some breads, and wine, due to cooking and filtering.
Serotonin is a neurotransmitter that affects many facets of human behavior, such as mood, stress response, appetite, and sexual drive. Up to 90% of your body's serotonin is produced by your gut microbiome, or the collection of healthy bacteria in your gut.
In addition, the gut microbiome plays a role in brain health. Research is beginning to show a connection between healthy gut bacteria and lower rates of depression.
Still, more research is needed to understand how probiotics may regulate mood.
Since up to 90% of your body's serotonin is produced in your gut, a healthy gut may correspond to a good mood. Fermented foods like kimchi, yogurt, kefir, kombucha, and sauerkraut are rich in probiotics that support gut health.
Bananas may help turn a frown upside down.
They're high in vitamin B6, which helps synthesize feel-good neurotransmitters like dopamine and serotonin.
Furthermore, one large banana (136 grams) provides 16 grams of sugar and 3.5 grams of fiber.
When paired with fiber, sugar is released slowly into your bloodstream, allowing for stable blood sugar levels and better mood control. Blood sugar levels that are too low may lead to irritability and mood swings.
Finally, this ubiquitous tropical fruit, especially when still showing green on the peel, is an excellent source of prebiotics, a type of fiber that helps feed healthy bacteria in your gut. A robust gut microbiome is associated with lower rates of mood disorders.
Bananas are a great source of natural sugar, vitamin B6, and prebiotic fiber, which work together to keep your blood sugar levels and mood stable.
Oats are a whole grain that can keep you in good spirits all morning. You can enjoy them in many forms, such as overnight oats, oatmeal, muesli, and granola.
They're an excellent source of fiber, providing 8 grams in a single raw cup (81 grams).
Fiber helps slow your digestion of carbs, allowing for a gradual release of sugar into the bloodstream to keep your energy levels stable.
In one study, those who ate 1.5–6 grams of fiber at breakfast reported better mood and energy levels. This was attributed to more stable blood sugar levels, which is important for controlling mood swings and irritability.
Although other sources of whole grains can have this effect, oats may be especially advantageous, as they're also a great source of iron, with 1 raw cup (81 grams) boasting 19% of your daily needs.
Iron deficiency anemia, one of the most common nutrient deficiencies, is associated with low iron intake. Its symptoms include fatigue, sluggishness, and mood disorders.
Some research suggests that people experience improvements in these symptoms after eating iron-rich foods or supplementing with iron, but more research is needed.
Oats provide fiber that can stabilize your blood sugar levels and boost your mood. They're also high in iron, which may improve mood symptoms in those with iron deficiency anemia.
Curiously, eating more fruits and vegetables is linked to lower rates of depression.
Although the mechanism isn't clear, a diet rich in antioxidants may help manage inflammation associated with depression and other mood disorders.
Berries pack a wide range of antioxidants and phenolic compounds, which play a key role in combatting oxidative stress — an imbalance of harmful compounds in your body.
They're particularly high in anthocyanins, a pigment that gives certain berries their purple-blue color. One study associated a diet rich in anthocyanins with a 39% lower risk of depression symptoms.
If you can't find them fresh, try buying frozen berries — which are frozen at their peak ripeness to retain the maximum amount of antioxidants.
Berries are rich in disease-fighting anthocyanins, which may lower your risk of depression.
7. Nuts and Seeds
Nuts and seeds are high in plant-based proteins, healthy fats, and fiber.
Additionally, they provide tryptophan, an amino acid responsible for producing mood-boosting serotonin. Almonds, cashews, peanuts, and walnuts, as well as pumpkin, sesame, and sunflower seeds, are excellent sources.
Moreover, nuts and seeds are a large component of both the MIND and Mediterranean diets, which may support a healthy brain. Each of these diets promotes fresh, whole foods and limits your intake of processed items.
What's more, a 10-year study in 15,980 people linked moderate nut intake to a 23% lower risk of depression.
Finally, certain nuts and seeds, such as Brazil nuts, almonds, and pine nuts, are good sources of zinc and selenium. Deficiency in these minerals, which are important for brain function, is associated with higher rates of depression — although more research is needed.
Certain nuts and seeds are high in tryptophan, zinc, and selenium, which may support brain function and lower your risk of depression.
Coffee is the world's most popular drink, and it may make the world a bit happier, too.
The caffeine in coffee prevents a naturally occurring compound called adenosine from attaching to brain receptors that promote tiredness, therefore increasing alertness and attention.
Moreover, it increases the release of mood-boosting neurotransmitters, such as dopamine and norepinephrine.
A study in 72 people found that both caffeinated and decaffeinated coffee significantly improved mood compared with a placebo beverage, suggesting that coffee contains other compounds that influence mood.
Researchers attributed this boost in attitude to various phenolic compounds, such as chlorogenic acid. Still, more research is needed.
Coffee provides numerous compounds, including caffeine and chlorogenic acid, that may boost your mood. Research suggests that decaf coffee may even have an effect.
9. Beans and Lentils
In addition to being high in fiber and plant-based protein, beans and lentils are full of feel-good nutrients.
They're an excellent source of B vitamins, which help improve mood by increasing levels of neurotransmitters like serotonin, dopamine, norepinephrine, and gamma aminobutyric acid (GABA), all of which are important for regulating mood.
Furthermore, B vitamins play a key role in nerve signaling, which allows proper communication between nerve cells. Low levels of these vitamins, especially B12 and folate, have been linked to mood disorders, such as depression.
Finally, they're a good source of zinc, magnesium, selenium, and non-heme iron, which may likewise elevate your spirits.
Beans and lentils are rich sources of mood-boosting nutrients, particularly B vitamins.
The Bottom Line
When feeling blue, you may crave calorie-rich, high sugar foods like ice cream or cookies to try to lift your spirits.
While this might give you a sugar rush, it's unlikely to help you in the long term — and may have negative consequences as well.
Instead, you should aim for wholesome foods that have been shown to not only boost your mood but also your overall health. Try out some of the foods above to kick-start your positivity routine.
While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
