Study shows egg may help alleviate depression

Thursday, March 29, 2012

Japanese researchers have found that an ingredient in eggs appears to alleviate depression.

A group led by Professor Mitsuhiro Furuse of Kyushu University’s graduate school of agriculture released the results of their study at a conference of the Japanese Society of Animal Science on Wednesday.

The group picked sample rats showing lower-than-usual levels of kinetic activity, a sign of depression. They then studied the duration the rats swam after feeding them with liquidated egg for a month.

The results showed that the rats fed with egg, kept swimming 1.3 times longer than other rats not on the special diet.

The study also found increased levels of tryptophan– a type of amino acid — in the prefrontal cortex of the brain of the rats that were fed with liquefied egg. Tryptophan is known to help alleviate depression.

The group says the study indicates the possibility that an ingredient in eggs helps boost levels of the amino acid, and helps alleviate some symptoms of depression.

Furuse says the study points to the importance of diet, although this study is limited to eggs. He says depression is normally treated with drugs, but the study indicates the possibility that nutritional improvement could help patients to reduce their reliance on drugs.
