Infant Nutrition and Development of Type 1 Diabetes – Is It Possible to Prevent Diabetes by Avoiding Cow’s Milk?

The long-awaited result of the TRIGR Study published this week shows that baby formula in which the cow’s milk proteins have been split does not prevent type 1 diabetes in children with genetic risk for type 1 diabetes.

Previous studies have reported that early exposure to complex foreign proteins, such as cow’s milk proteins, may increase the risk of type 1 diabetes in individuals with genetic risk for type 1 diabetes.

“In 2002, we therefore embarked on a large-scale study on 2159 infants with a family member affected by type 1 diabetes and with genetic risk for type 1 diabetes, to find an answer to the question whether delaying the exposure to complex foreign proteins will decrease the risk of diabetes,” says Anita Nucci, PhD, RD, LD from Georgia State University, the USA coordinator for the study, and Professor Mikael Knip from the University of Helsinki, the leader of the international TRIGR study (

After breastfeeding infants were either weaned to a special formula (extensively hydrolyzed casein formula), with the cow’s milk proteins split into small peptides (small pieces of the protein), or a regular cow’s milk based formula with intact cow’s milk proteins. Infants received the study formula for at least 2 months until the age of 6-8 months and at the same time avoided cow´s milk proteins from all other food sources. All subjects were followed for at least 10 years to assess the numbers of children who developed diabetes.

The results show that in this large international randomized trial, weaning to an extensively hydrolyzed casein formula during infancy did not result in a reduction in the incidence of type 1 diabetes compared to regular intact cow’s-milk-based formula after about 11.5 years of follow up. This study provides an answer to a long term controversial area regarding the potential role of cow milk formula in the development of Type 1 diabetes . Accordingly, there is no evidence to revise the current dietary recommendations for infants at high risk for type 1 diabetes.

The study conducted in 15 countries around the word was mainly funded by the National Institutes of Health (NIH), the Canadian Institutes of Health Research (CIHR) and the Commission of the European Communities.
