Fish cures depression!: "People with a diet low in fish oil have an increased risk of mood disorders, heart conditions and other general health problems, research shows. Researchers at Sydney's Black Dog Institute found high rates of depression and bipolar disorder could be linked to an omega-3 fatty acids deficiency. Such acids are found in seafood and plants including flaxseed, walnuts and canola oil. Institute executive director Professor Gordon Parker said there was growing interest in the possible role of diet in the increasing rates of depression in Western societies. He said changes in diet over the past 150 years, which have seen omega-3 fatty acids replaced by saturated fats and omega-6 acids from vegetable oils, could be linked to the rise in cardiovascular disease, depression and other neurological disorders."
