A report by seven researchers has concluded the milk may trigger type 1 diabetes. The researchers say:
“The evidence for milk and, particularly A1 β-casein, as a primary dietary trigger for type 1 diabetes is intriguing although causation remains unproven. The ecological evidence across populations is particularly strong. Exclusive breastfeeding is widely regarded as being protective against type 1 diabetes in early infancy, but its benefits may be lost if the mother supplements breast milk with cows’ milk formula, or if the duration of breastfeeding is too short. It is also conceivable that some dietary triggers might cross into breast milk. These factors might contribute to the inconsistencies in the reported associations between breastfeeding and type 1 diabetes.”
