• Chocolate is rich in many mood-boosting compounds. Its sugar may improve mood since it’s a quick source of fuel for your brain.
• It may release a cascade of feel-good compounds, such as caffeine, theobromine, and N-acylethanolamine — a substance chemically similar to cannabinoids that have been linked to improved mood.
• 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
• Chocolate has a high hedonic rating, meaning that its pleasurable taste, texture, and smell may also promote a 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.

• 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, which include kimchi, yogurt, kefir, kombucha, and sauerkraut, may improve gut health and mood.
• The fermentation process allows live bacteria to thrive in foods that are then able to convert sugars into alcohol and acids.
• 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 bread, and wine, due to cooking and filtering.

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.

Oats provide the 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.

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.

Nuts and seeds are high in plant-based proteins, healthy fats, and fiber.

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.

• 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.
