Vitamin D Research Papers Meaning Of Critical Thinking
“Maybe people will stop taking vitamin D supplements, but somehow I doubt it.Vitamin D may also play a role in muscle function and the immune system.You can get vitamin D through sun exposure, your diet, and supplements.Vitamin D is produced when your skin is exposed to sunshine.
Other ways vitamin D is thought to help us, and how much we would need to take, is an area of active research (and controversy).
Of course, there are some cases when supplementation can be helpful: During pregnancy, for example, or for people who have been diagnosed with health conditions that may lead to vitamin deficiencies, like liver disease or multiple sclerosis.
People with asthma, those who don’t get into the sun at all (like the homebound or institutionalized), or those from ethnic backgrounds with darker skin — African, Afro-Caribbean, and South Asian — may also benefit from a supplement.
And early observational research on the benefits of vitamin D uncovered associations between higher levels of vitamin D intake and a range of health benefits. More recent randomized trials — that introduce vitamin D to one group and compare that group with a control group — have shown little or unclear benefit for both vitamin D testing and supplementation in the general population.
But the studies could only tell about correlations between vitamin D exposure and disease outcomes, not whether one caused the other. And reviews that take these trials together to come to more fully supported conclusions, like the paper, are similarly lackluster.
In 2010, the Institute of Medicine (now known as the National Academy of Medicine) brought together an expert committee to review the evidence on the vitamin and figure out whether there was a widespread deficiency problem in North America.
