2 . Of all the problems that people face today, depression proves to be one of the hardest to pinpoint. People often suffer secretly, not wanting to admit their need of professional help. They continue with their normal routines and, many times, unhealthy eating habits. Now, health professionals are actually linking diet and depression and have found success in using diet to treat the disorder.

Several researchers and Australian institutions at Deakin University in Victoria, Australia, set out to evaluate the direct link between diet and depression. They carried out the study over a 12-week period and observed 67 patients with moderate to severe depression. For their control group, the patients received social support rather than switching their eating habits to a well-balanced diet. The other patients then received dietary counseling sessions where they were advised to eat a diet high in fruits, vegetables, and lean meats. After the trial period, over 30 percent of the patients had gone into remission with their depression. Only 8 percent of the control group actually experienced this same improvement. This trial has greatly helped researchers understand and better help patients suffering from depression.

Most Americans today do not associate their diet and depression together. Nearly 60 percent of Americans eat over processed foods. 90 percent of added sugar comes from these processed foods. For people with depression, this diet might give a short energy burst, but it will eventually cause energy to sink, bringing happy moods down with it. Many people also love caffeine, drinking multiple cups each day. Again, they consume extra sugar. However, the caffeine can also disrupt sleep and cause anxiety. In addition, people with depression may have a tendency to turn to alcohol Unfortunately, alcohol depresses the central nervous system, which will directly influence a person’s mood for the worse, especially those dealing with depression.

According to the research, diet and depression do go hand in hand. Those suffering from depression should do away with processed foods as much as possible. With a few simple changes in lifestyle, these patients can improve their mental health and return to normal activities with renewed energy and joy.
