Can your diet and health change your breast milk? Review uncovers the key maternal and birth factors

Sun, 08/03/2025 - 23:40
This review highlights how maternal, obstetrical, and neonatal factors influence the energy and macronutrient content of breast milk. The findings underscore significant variability in milk composition, with implications for tailored nutritional support in early life.

Metformin’s blood sugar control starts in the brain, not just the liver, study finds

Sun, 08/03/2025 - 22:40
Low, clinically relevant doses of metformin lower blood glucose by inhibiting the Rap1 protein in specific neurons of the hypothalamus, revealing a brain-first mechanism. This action is essential for metformin’s effect at therapeutic doses and highlights new directions for diabetes treatment.

AI spots hidden diabetes risk even when test results look normal

Sun, 08/03/2025 - 22:03
Researchers used continuous glucose monitoring and multimodal data from over 3,000 people to reveal hidden patterns in glucose spikes across normoglycemia, prediabetes, and type 2 diabetes. Their AI-driven model exposed high individual variability and offers a personalized path for early detection and prevention of diabetes.
