Fish Consumption and Suicide

Does poor diet lead to depression or depression lead to a poor diet? Maybe people who feel lousy eat lousy to reflect their mood.

A study following people who weren’t depressed over 6 years found those with higher carotenoid intake (fruits and veggies) were 28 percent less likely to get depression.

In a study of suicide across the European Union, Greece had the lowest rates of suicide.

In a study, 10,000 people were followed for years showed those on a Mediterranean diet were less likely to be depressed. Wasn’t due to red wine or fish, but fruits, nuts, legumes and higher plant fat versus animal fat sources. Those with higher dairy and meat consumption showed increased rates of depression.

Similar results from a Japanese study of men and women. Higher intake of vegetables fruits, mushrooms and soy products was associated with less depression. The benefits were not due to seafood, such as fish or shellfish.

Another study following 100,000 Japanese men and women for 10 years found no evidence of higher fish intake protecting against suicide. In fact, study found increased risk of suicide in highest fish omega-3 fatty acid intakes in nondrinkers.

Same results in a Mediterranean study, showing higher fish consumption linked to higher risk of mental disorders. One explanation is the mercury found in fish causes neurological damage. The increased risk of suicide in people who eat lots of fish may be due to the mercury in fish.

A Harvard study of 205,357 people for up to 20 years found no evidence that fish lowered suicide rates, with a trend towards increased suicide risk.

There was previous evidence omega-3 was useful in treating depression and suicide, but that could have been publication bias. Trials that showed no benefit did not get published, leaving only trials that linked a benefit to omega-3 and fish oils.
