This study, executed by medical schools in Boston, USA, explored whether magnesium intake is associated with a lower risk of diabetes type 2, especially in the context of a diet low in cereal fiber and high in low-quality carbohydrates, which provide quick energy but are mainly devoid of nutrients. Dietary magnesium intake was assessed by food questionnaires every 4 years. Questionnaires also determined the incidence of type 2 diabetes. Type 2 diabetes incidence was documented over 28 years of follow-up. Analyses showed that participants with the highest magnesium intake had a 15% lower risk of developing type 2 diabetes compared with those with the most insufficient magnesium intake. Additionally, higher magnesium intake was more strongly associated with a lower risk of type 2 diabetes among participants consuming carbohydrates of low quality. In conclusion, higher magnesium intake is associated with a lower risk of type 2 diabetes, especially in those consuming carbohydrates of lower quality. More details can be found in the study.
