Older adults with high vitamin D levels may be less likely to develop dementia, according to a six-year, multiethnic study.
Investigators followed more than 1,700 study participants aged 65 or more years without dementia. Participants were assessed using follow‐up visits and food frequency questionnaires. About 320 were subsequently diagnosed with dementia.
Participants with the highest levels of vitamin D intake from food had a lower risk of dementia over time when compared with participants who consumed the least vitamin D from food

发现VD是目前国际上最受关注的营养素和研究的热点之一, 曾搜到个网站, 里面集中收集的都是VD相关的文章, 罗列了几十种疾病与VD研究论文链接.
依据个人目前阅读的这么多文献比较看, 25-(OH)VD标准范围设定20-80最靠谱. 处于40-60间是我给自己定的最理想安全值:)
俺每日5000IU, 数月后只从21变成24。
俺闺女VD也才21。难道遗传了？
