However, these studies have their limitations, including the race and location of participants
There are, of course, limitations to the studies. One is that the recipients were healthy middle-to-upper-middle-class Caucasians who lived in areas with sunny weather. Other studies have shown that Hispanics, Blacks, and Native Americans are at a higher risk of developing type 2 diabetes. They face vitamin D deficiencies due to the amount of melanin in their skin.
Further studies need to be done to prove that sufficient vitamin D levels will prevent chronic disease. Currently, the studies only show that vitamin D impacts disorders connected to the bones like osteomalacia and osteoporosis.
