The study supports the thought that early allergen exposure increases the tolerance and lowers the risk of childhood food allergies. The study compared women who ate nuts five or more times a month compared to those who ate nuts less than once a month.
It was also noted that nursing mothers who avoided peanuts and milk products did NOT affect their child’s risk for food allergies. This means that avoidance of those products may not be beneficial to the child, whereas for pregnant women consuming them WAS helpful.
Also, peanut butter is a good source of folic acid and protein–both of which are needed in pregnant women.
