Fish Oil and Depression: How to Make Depression A Thing of the Past With all the research done to know more about the virtues of fish oil and Omega-3, it’s no surprise that we constantly learn about new benefits to consuming, or adding these supplements into our dietary regimen. Not only does omega-3 give you a healthier heart, protects you from certain diseases and lowers your cholesterol levels, studies have recently found that omega-3, and food items that are rich in omega-3 such as fish oils, can reduce the effects of depression as well. Depression is a type of mood disorder associated with low mood and aversion to activity that can affect a person's thoughts, behavior, feelings and sense of well-being.Those that suffer from depression can feel sad, anxious, empty, hopeless, worried, helpless, and even worthless. They may lose interest in activities that once were pleasurable, experience loss of appetite or overeating, have problems concentrating, remembering details, or making decisions, and, in severe cases, may contemplate, attempt, or commit suicide. And to make things worse, insomnia, excessive sleeping, fatigue, loss of energy, or aches, pains, or digestive problems may also be present during depression. Now you may be wondering, what does omega-3 have to do with depression? Well, according to researchers, the answer lies in the reduced intake of long-chain omega-3 fatty acids. The researchers have deduced that since one of the benefits of high-dose fish oil is to increase serotonin levels, it is not unreasonable to think that the decrease in fish oil consumption in the past century led to a decrease in the natural levels of serotonin in the brain.Serotonin is the body’s natural anti-depressant and is popularly thought to be a contributor to feelings of well-being and happiness.
