low fat yogurt is bad when pregnant

Summary- Pregnant women who eat low fat yogurt have a higher risk for their child developing asthma and hay fever. Results showed that milk intake while pregnant was not associated with developing asthma, but it actually protected against asthma. Women who ate low fat yogurt with fruit once a day were 1.6 times more likely to have children who have asthma by age 7, compared to women who didn't eat low fat yogurt.

Impact- This can impact children in the future, because a lot of people eat low fat yogurt.
Critique- This is interesting how some yogurt can cause asthma in children. I would have never guessed that yogurt would be the cause of asthma and hay fever.
