### How Breastfeeding May Help Prevent Type 2 Diabetes
Recent research suggests that breastfeeding can help prevent type 2 diabetes by improving metabolic health. This improvement is due to an increase in the number of beta cells in the pancreas and a boost in insulin production. A study published in April 2020 in *Science Translational Medicine* followed 85 women who breastfed and 99 who did not. Initially, both groups had similar glucose tolerance. However, after 3.6 years, the breastfeeding group showed better glucose tolerance and higher insulin sensitivity.
In animal studies, the hormone prolactin, which stimulates milk production, also caused more beta cells to grow in the pancreas. These cells help produce insulin, which is crucial for regulating blood sugar levels. Even after weaning, the mice that breastfed had more beta cells and higher insulin production.
Previous studies also support these findings. For example, a 2017 study found that women who breastfed for up to six months were 25% less likely to develop type 2 diabetes, and those who breastfed longer had their risk reduced by more than half. Another study in 2015 showed that even women who supplemented breastfeeding with formula had a lower risk of developing diabetes.
While breastfeeding has clear benefits, it is not the only way to reduce the risk of type 2 diabetes. Lifestyle changes such as regular exercise and a healthy diet can also help. Foods with a lower glycemic index, such as whole grains, fruits, and vegetables, are particularly beneficial.
In summary, breastfeeding can have long-term benefits for metabolic health and may significantly reduce the risk of developing type 2 diabetes. However, other healthy lifestyle choices are also important in managing diabetes risk.
