The consumption of fats doesn’t seem like an obvious way to eliminate depression, but if you increase your omega-3 fatty acids, like those found in fish oil, it can actually improve the function of your brain. High levels of omega-3 are also linked to more restful sleep, decreased incidences of insomnia and lower anxiety levels. The anti-inflammatory and heart health benefits of omega-3 fatty acids can also lower overall stress on the body, which can help prevent depressive episodes. Fish oil supplements are widely available around the world, and deliver a concentrated dose of these beneficial fats.
