10.Health experts have long known that vitamin D is important for healthy bones and teeth.It may also help to protect the body against diseases such as diabetes and cancer.And now,researchers say vitamin D might help fight brain diseases called dementias(痴呆).Dementias are brain diseases that damage thinking and memory processes,what scientists call"cognitive abilities."Dementias are difficult to treat.Taking care of someone who has dementia is extremely demanding.And the disease is very frightening to sufferers.Chris Roberts suffers from dementia.He says the worst part of living with this disease was getting lost while driving."The worst thing that I found was getting lost in the car,not just forgetting where I was going-I wouldn't know where I was."More than 47million people around the world suffer from dementia.The World Health Organization reports that 60percent of them live in low-and middle-income countries.
We get vitamin D from some foods like nuts,lentils and fatty fish.We also get vitamin D from the sun.But that is not dependable.In some parts of the world,there is not enough sunlight to provide enough vitamin D.Also,sunblock substances prevent the vitamin from entering the body.To add to the problem,the skin's ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia.The team recently measured vitamin D levels and cognitive ability in older people.Nutritional sciences professor Joshua Miller led the team.He said cognitive abilities differed among the study subjects.He said tests showed that about 60percent of the group was low in vitamin D.
