Infants who are at genetic risk of developing type 1 diabetes and who were given probiotics before 3 months of age had a 33% reduction in the risk of pancreatic beta-cell islet autoimmunity, according to new results from an ongoing international study in over 7000 children.

Ulla Uusitalo, PhD, a nutritionist at the University of South Florida, Tampa, and a member of The Environmental Determinants of Diabetes in the Young (TEDDY) study, presented the results at the European Association for the Study of Diabetes 2014 Meeting.

Probiotics containing mainly Lactobacillus and Bifidobacteriumwere given either as a supplement or in probiotic-fortified infant formula.

The TEDDY study is an ongoing prospective birth-cohort study of 8676 children carrying type 1 diabetes–associated HLA-DR-DQ alleles. It started in 2004 in Finland, Sweden, the United States (Colorado, Georgia, and Washington State), and Germany.
