Studies examining the role of nutrition in depression are surprisingly sparse, but if you read between the lines, the connection is
definitely there. Most professionals still do not focus on nutrition as a contributing factor to depression.
The primary emphasis is still on issues such as a neurochemical aberration, stress, and the like. But from own perspective, doctor believe that nutrition is a factor in about 25 percent of depressed individuals.
Moreover, nutritional deficiencies are common in depressed people, adds doctor, though which comes first—deficiency or depression—isn’t entirely clear. “If people haven’t been eating right their whole lives, it can start to catch up with them in their forties or fifties. And if they have a tendency toward depression, it often shows up around the same time,” he says.
While poor nutrition probably doesn’t cause depression, correcting a deficiency can be beneficial if you’re battling it, says doctor. But nutritional supplements are no substitute for professional evaluation. “If you think you’re depressed,” he advises, “it’s crucial that you see a physician or psychiatrist for help.”
