London, May 19 (ANI): Lack of Vitamin D, which we get from the sun, can cause depression, suggests a joint Italian and US study.
People aged over 65, and women face a higher risk of depression if they have Vitamin D deficiency.
Scientific studies show that vitamin D affects parts of the brain directly involved in learning and memory and possibly even maternal and social behaviour, reports the Daily Express.
Depression in the elderly can increase the risk of becoming ill, worsen the outcome of some illnesses and could increase the chances of dying.
There is a link between our moods and what we eat too, researchers say.
Ingredients such as zinc, omega-3, folate, St John's wort, green tea and red clover may help to reduce the symptoms of depression.
World Health Organisation has forecast that within 20 years, depression will be the leading cause of disability worldwide, with around 120 million people affected. (ANI)
