Many things can cause depression, such as financial trouble, the loss of a loved one or an illness. In addition, there may not be a concrete reason for your depression.

However, experts have pinpointed a few surprising things that can cause depression – that most people would never suspect.

1. Not Getting Enough Omega-3

Low intake of omega-3 fatty acids, found in salmon and vegetable oils, may be associated with a greater risk of depression. A 2004 Finnish study found an association between eating less fish and depression in women, but not in men. These fatty acids regulate neurotransmitters like serotonin, which could explain the link. Fish oil supplements may work too; at least one study found they helped depression in people with bipolar disorder.
