The Facts:
* About 4,100 African American women took part in a study to investigate the link between dietary magnesium and calcium and the risk of developing type 2 diabetes.
* Food intake questionnaires completed over an 8-year period showed that women with a low intake of dietary magnesium had a greater risk of developing type 2 diabetes than those who had a higher intake.
* Women who ate whole grains and low-fat dairy produce daily were less likely to develop type 2 diabetes than those who ate these foodstuffs less than once a week.
Shaun’s comment: It is becoming increasingly common to test treatments in different ethnic groups. There are many examples of where certain treatments work better in one group than another, and this is almost certainly related to the different groups having some different genes. This is of particular relevance in New Zealand where we have several major ethnic groups. This study confirms previous research showing that magnesium in the diet can reduce the chances of getting diabetes, and that this occurs in another ethnic group.
