Infant nutrition and development of type 1 diabetes

Previous studies have indicated that early exposure to complex foreign proteins, such as cow's milk proteins, increases the risk of type 1 diabetes in predisposed individuals.

"Therefore, In 2002, we embarked on a large-scale study on more than 2100 infants with a family member affected by and with genetic disease susceptibility to find an answer to the question whether delaying the exposure to complex foreign proteins will decrease the risk of diabetes", tells Professor Mikael Knip from the University of Helsinki, the leader of the TRIGR Study.

After breastfeeding the babies were either weaned to a special formula, where the cow's milk proteins were split into small peptides, or to a conventional infant formula with the regular cow's .

The first study endpoint was positivity for at least two -associated autoantibodies by the age of six years.

The results show that there was no difference in the appearance of autoantibodies between the two study groups. However, the disease process resulting in has clearly two phases, the first being the appearance of autoantibodies and the other the progression from autoantibody positivity to clinical disease.

"The current results do not exclude the possibility that the early dietary modification may affect the latter phase, and therefore it is extremely important to continue to follow the study participants into the final endpoint, which is the age of ten years. That endpoint will be reached in 2017", Professor Knip states.
