Depression and diet
Abstract
Especially low vitamin B12 or folate and low intake of omega-3-fatty acids, but also low vitamin D may associate with increased risk of depression. B12 and folate may also be useful in the treatment of depression. The importance of individual fatty acids is unclear. The causal relationship between depression and diet, the efficacy of vitamins or dietary supplements in the treatment of depression, or the impact of diet compared with other treatment options need to be scrutinized. An overall healthy diet rich in vitamin B12, D or folate and fish oils may have positive effect also on depression.
