[Researchers] obtained macrophage cells from diabetics and non-diabetics, with and without vitamin D deficiency. When the cells were exposed cells to cholesterol and low vitamin D levels, they found that low vitamin D levels in the culture dish resulted in fewer macrophages becoming foam cells.
On the other hand, when the human macrophages were placed in a vitamin D-rich environment, the uptake of cholesterol was suppressed, and they don't become foam cells, said Bernal-Mizrachi.
The researchers noted that it may be possible to delay or reverse the development of atherosclerosis in diabetics by helping them regain adequate vitamin D levels.
Recently, in a post of about children and their need for vitamin D, Dr. Fuhrman explains it get be difficult to get sufficient vitamin D from food, unless you are spending a lot time outdoors, and even then its tough.
A sufficient amount of vitamin D is difficult to obtain from dietary sources. It is possible to obtain vitamin D from direct sun exposure—without sunscreen (sunscreens block UV-B rays they in turn prevent the body from converting vitamin D). However, since the generous amount of sunshine necessary to assure sufficient vitamin D exposure is potentially harmful and because children often spend too much time indoors watching television, playing video games, or on the computer, it is advisable for all children to assure vitamin D levels with supplements, not sunshine.
To help you get your vitamin D, Dr. Fuhrman recommends his supplement Osteo-Sun, for both children and adults.
