Does fast food contribute to depression? Can a healthy diet combat mental illness?
In an unusual experiment, James Cook University researchers in Australia have found that among Torres Strait Islander people the amount of fish and processed food eaten is related to depression.
A JCU research team led by Professors Zoltan Sarnyai and Robyn McDermott looked at the link between depression and diet on a Torres Strait island, where fast food is available, and on a more isolated island, which has no fast food outlets.
Dr. Maximus Berger, the lead author of the study, said the team interviewed about 100 people on both islands.
“We asked them about their diet, screened them for their levels of depression and took blood samples. As you’d expect, people on the more isolated island with no fast food outlets reported significantly higher seafood consumption and lower take-away food consumption compared with people on the other island,” he said.
The researchers identified nineteen people as having moderate to severe depressive symptoms: sixteen were from the island where fast food is readily available, but only three from the other island.
“People with major depressive symptoms were both younger and had higher take-away food consumption,” said Dr. Berger.
