This seems like common sense to me, but I guess any positive news about dairy is good news!
A study using 62 rats found those that didn’t have enough calcium in their diet, and were breastfeeding, were more likely to have deteriorating bone around their teeth and gums.
Breastfeeding rats that had enough calcium didn’t suffer any bone loss. Experts said the demands for calcium are greater immediately after a baby is born. They said studies in humans are needed to confirm the findings.
The study also found rats that had low calcium levels but were not breastfeeding had some bone loss, however, it was not as significant as those that were breastfeeding. Experts recommend women undergo a periodontal exam when they find out they are pregnant, and have more frequent teeth cleanings during pregnancy and up to 3 months after delivery.
