Women who are already obese at the beginning of their pregnancy are more likely not to pass on the appropriate levels of vitamin D to their babies, according to new research.
Researchers at Northwestern University explained that because vitamin D is fat-soluble, it tends to be absorbed by overweight people. Consequently, obese people will have lower levels of this important vitamin in their blood.
Their inference was confirmed when they found that slim women's babies had a third more vitamin D than babies born to obese mothers.
"Nearly all of mothers in this study reported taking prenatal vitamins, which may be the reason why their own vitamin D levels were sufficient, but the babies born to the obese mothers had reduced levels of vitamin D," commented Jami L Josefson, author of the study.
"It’s possible that vitamin D may get sequestered in excess fat and not transferred sufficiently from an obese pregnant woman to her baby."
Vitamin D is important for the upkeep of the human body and is derived mainly from the sun. Other sources include oily fish like salmon, eggs and fortified breakfast cereals.
