Shanice Young is three months pregnant with her second child, and has some nutty cravings. "I'm kind of like addicted to Hershey's with Almonds.
The 27 year-old eats some form of nuts just about every day. A new study finds mothers who eat nuts while pregnant are less likely to have children with peanut or tree nut allergies.
"Women who ate peanuts and tree nuts more than five times a week -- their children had 30 percent reduction in allergies," said Dr. Michael Young with the Harvard Medical School.
The number of kids with peanut allergies in the U.S. has more than tripled in the past two decades. Those allergies cause everything from skin reactions to abdominal issues to severe respiratory problems, even death. While nuts are a good source of protein and folic acid to prevent birth defects, doctors want more proof before they recommend pregnant women eat more of them. "We need more evidence before we can say with certainty that women should eat nuts during pregnancy to prevent nut allergy in their children," said Dr. Anna Nowak-Wegrzyn with the Icahn School of Medicine at Mount Sinai.
Shanice's first child, three year old Lennox, has no known allergies. "If my normal diet is preventing my unborn child from getting a nut allergy, great," she said.
Now she's hoping for a healthy baby girl.
