Comparison Between Antenatal and Postnatal Colostrum From Women With and Without Type 1 Diabetes.
Alexandra Goldberg, Hans Pettersson, Cecilia Ekéus and 3 others
PMID 40071794WHAT IT FOUND
Colostrum fat, carbohydrate, and kcal did not differ between mothers with and without type 1 diabetes; protein changed over time.
Antenatal colostrum had higher protein than formula and resembled day 1 postnatal colostrum.
Key findings
01Fat, carbohydrate, and kcal in colostrum were similar between women with and without type 1 diabetes, while protein differed in a pattern that changed across time points (p = 0.01).
02Antenatal colostrum and day 1 postnatal colostrum had higher protein than postnatal days 2 to 5, and lower fat and carbohydrate than later postnatal days.
03Commercial formula had higher fat and carbohydrate and lower protein than day 1 postnatal colostrum (fat 3.5 vs 2.1 g/100 ml; carbohydrate 7.2 vs 6.2 g/100 ml; protein 1.3 vs 4.1 g/100 ml).

What it does not show
The study included only 20 women, and no formal power analysis was done, so it may miss real differences. Colostrum samples were not collected at the same time of day, and some time points were missing. Maternal diet, health conditions, and medication were not controlled. Participants were recruited in Stockholm, and women with type 1 diabetes came from one clinic, so results may not apply elsewhere. 18 of the 20 participants had a university degree, so diet and lifestyle may differ from other groups. Commercial formula was compared using label values, not laboratory measurement. The study measured colostrum composition; it did not test whether colostrum feeding prevents neonatal hypoglycemia.
The easy way to misread this
Do not conclude that antenatal colostrum prevents neonatal hypoglycemia. This study measured colostrum composition in 20 women and did not test feeding as an intervention. The composition differences do not prove a clinical outcome.
