In a new study, researchers found that a higher intake of manganese is associated with a lower type 2 diabetes risk among older women.
The research was conducted by a team at Brown University.
The team evaluated the association between manganese intake and the risk for type 2 diabetes in 84,285 postmenopausal women without a history of diabetes.
Results were validated in the 62,338 women who participated in the WHI-Clinical Trial (WHI-CT).
The researchers found that compared with the women who had the lowest intake of manganese, women with the highest intake had a lower risk for type 2 diabetes.
In an analysis of biomarkers of inflammation and endothelial dysfunction, the team found a higher intake of manganese was linked to lower circulating levels of inflammation that strongly mediated the association between dietary manganese and type 2 diabetes risk.
The team says consumption of food groups rich in manganese could potentially help fight against type 2 diabetes risk in postmenopausal women.
Foods high in manganese include nuts, beans, cereals, brown rice, leafy green vegetables, fruits, and dark chocolate.
One author of the study is Jung Ho Gong, from Brown University.
The study is published in Diabetes Care.
