Magnesium is an essential mineral for general good health, affecting every cell in our bodies. According to a new meta-analysis by researchers from Zhejiang University and Zhengzhou University in China, a diet rich in magnesium may reduce the risk of diseases including coronary heart disease, stroke and type 2 diabetes. This analysis of the evidence on health outcomes involved data from more than one million people across nine countries. They found people in the highest category of dietary magnesium consumption had a 10 per cent lower risk of coronary heart disease, 12 per cent lower risk of stroke and a 26 per cent lower risk of type 2 diabetes compared to those in the lowest category. Their results also indicate that an extra 100mg per day of dietary magnesium could reduce risk of stroke by 7 per cent and type 2 diabetes by 19 per cent.
