The lack of vitamin D can increase the risk of depression by up to 75% in the elderly, according to a study by members of Trinity College in Dublin (Ireland) after four years of research.
In order to arrive at this conclusion, these specialists analyzed health data from 3,965 people over 50 years and examined them two and four years later, during which 400 people developed depression.
Robert Briggs, one of the scientists involved, says it is "the widest and most representative study of the risk of depression and vitamin D status in older adults in Ireland."
Therefore, these researchers believe that vitamin D can protect the age-old brains from wear, although they estimate that more studies are needed to find out if this is the case.
It is not difficult to find nutritional supplements of this kind and are relatively safe. However, those who are responsible for this research request have updated the guidelines to more accurately determine the recommended intake of vitamin D.
According to MedlinePlus, foods containing vitamin D are naturally: cheese, mushrooms, fatty fish, such as salmon, tuna and mackerel, beef liver and eggs.
