No one is immune to the occasional bad mood. Whether it's the weather, waking up on the wrong side of the bed or another variable, various factors can have an adverse affect on a person's mood.
Food is one factor that can have a positive effect on mood. Certain foods have been found to positively affect mood, so incorporating them into your diet may help you stay positive even on those days when you get up on the wrong side of the bed.
• Fatty fish: A study from British researchers published in the Archives of General Psychiatry found that a daily dose of an omega-3 fatty acid called eicosapentaenoic acid, or EPA, helped patients with depression significantly reduce their feelings of sadness and pessimism. Hackensack Meridian Health notes that salmon, albacore tuna, sardines, trout, and anchovies are rich in omega-3 fatty acids.
• Nuts and seeds: The minerals selenium, copper, magnesium, manganese, and zinc have all been linked to mental health, and nuts are rich in each of those minerals. Hackensack Meridian Health notes that almonds, sunflower seeds, pumpkin seeds, walnuts, and peanuts are particularly good sources of the immune system-boosting minerals zinc and magnesium.
• Dark, leafy greens: Dark, leafy greens like kale, spinach and collards are rich in iron and magnesium, both of which can increase serotonin levels and help reduce feelings of anxiety. Dark, leafy greens also help the body fight inflammation, which can have a positive effect on mood. A 2015 study published in the journal JAMA Psychiatry found that brain inflammation contributed to certain behaviors, including low mood, that appear during major depressive episodes.
• Dark chocolate: Chocolate lovers may be happy to learn that dark chocolate can improve mood. A 2009 study published in the Journal of Proteome Research found that dark chocolate helped to reduce levels of the hormone cortisol, which has been linked to stress. Hackensack Meridian Health notes that, when consumed in moderation, dark chocolate made of at least 70 percent cocoa can help people relax.
Various foods can have a beneficial effect on mood, potentially helping people to stay positive when doing so proves challenging.
