Newborn Allergies – It’s no secret that young children are having a massive increase in allergy issues. But one researcher thought he could turn the tide of allergies…wait for it…by giving pregnant mothers probiotics! To test this theory, Dr. Ortiz-Andrellucchi gave expecting mothers 6 weeks of L. casei supplementation. This supplementation increased the milk’s concentration of T helper-1 and T helper-2 cells in the mother’s milk, compared to the placebo group. So this was a very good sign that the Lactobacillus casei was doing something.
