Studies have shown that high intake of omega-6 oils (corn, safflower, sunflower, peanut, canola, and soybean oils) increases the risks of major depression because it increases inflammation in the brain.
On the other hand, omega-3 oils - especially their DHA (fatty acid) component - have been associated with reductions in depression, particularly in the orbitofrontal cortex. Low DHA levels in this brain area are also associated with bipolar disorder.
There is evidence that the medications used to treat bipolar disorders may work by altering the effects of DHA on the brain. Lithium, one of the most effective treatments for bipolar mania, improves DHA effectiveness.
Another study found that diets high in omega-6 oils and low in omega-3 oils (the typical American diet of processed foods) were associated with depression and neurotic behavior.

A separate study found that college students under stress who were also low in omega-3 intake had greater stress-induced elevations in inflammatory cytokines than students with higher DHA levels. This stress-related increase in brain inflammation gets much worse as we age, meaning that higher DHA intake is vital for brain protection.
Populations such as the Japanese, Koreans, and Norwegians, who eat a diet high in omega-3 fatty acids, show much lower rates of depression, bipolar disorder, and suicide risk.
What all this means is that you should avoid processed foods and take high-quality DHA supplements daily. The average adult should get around 1,000 mg of omega-3 oils a day. A high-DHA, low-EPA (fatty acid) supplement is best. Children under age 14 can take 200 mg a day; pregnant women can take around 1,000 mg a day.
a frog has in common with a bird ? Depression is a mental disorder that like most mental disorders are being produced by our system. However they get into the sphere of pathology and need treatment when they recurr, keep on for a long time and are also intense. What you eat and drink have nothing to do with them.
