After controlling for birth weight, the duration of pregnancy, maternal allergies and many other factors, they found that 17 weeks was the crucial age: babies who were introduced to solids before this age were significantly more likely to develop food allergies.

“Don’t introduce solids until 17 weeks,” said the lead author, Kate E. C. Grimshaw, a nutritionist at the University of Southampton, “and if you can wait longer, that’s fine, too. At whatever age you begin solid foods, you should continue breast-feeding as well. And for those who cannot breast-feed, the advice not to introduce solid foods until 17 weeks is still applicable.”
