Requirements For Vitamin D
It has been found that bone loss in post menopause
women occurs mostly in the winter due to falling levels of vitamin D products in the blood. A winter intake
from fortified foods or supplements is strongly recommended to promote bone health. Winter intakes of about
15 ug (micrograms) per day appear to be appropriate to prevent bone loss.
There is growing evidence that low vitamin D levels
contribute to cancer and auto immune disease. If we lived as we evolved - in the open nearer the equator -
we would synthesise vitamin D from sunlight equivalent to 100 ug (micrograms) or more per day and dietary
intake would be irrelevant.
Adult vegans obtain adequate vitamin D if they
regularly spend time outdoors in spring, summer and autumn. A dietary intake of the vitamin in the winter
can be ensured by eating fortified foods or taking supplements. In northern latitudes vegan women who are
breast feeding should ensure their intake during winter by using fortified foods or taking supplements.
Parents are advised to include vitamin D fortified foods or supplements if they wean their infants during
the winter months, especially if they are dark skinned.
