Getting enough magnesium in your diet could help prevent diabetes, a new study suggests.
People who consume high amounts of magnesium in foods and from vitamin supplements are about half as likely to develop diabetes as compared to those who do not take enough magnesium concludes a new study by Dr. Ka He of the University of North Carolina, USA.
Dr Ka He et al studied magnesium intake and diabetes risk in 4,497 men and women 18 to 30 years old, none of whom were diabetic to start with. During a 20-year follow-up period, 330 of the subjects developed diabetes and it was found that people with the high magnesium intake (200 mg of magnesium for every 1,000 calories consumed) were 47 percent less likely to develop diabetes than those with the low intakes.
This inference can have a great significance for Europe. A 2002 study called ‘Diabetes trends in Europe’ predicted an epidemic expansion of diabetes incidence in Europe. Carried out by Saint-Louis Hospital, Paris, France, the study evaluated trends in type 1 and type 2 diabetes in seven European countries (Finland, Denmark, the UK, Germany, France, Spain, and Italy). It found increasing incidence of type 1 and type 2 diabetes in most European countries. The report also mentioned that costs of in-hospital diabetic care have increased even more rapidly than has the number of affected patients .
Magnesium is essential to many processes in our body. Magnesium plays a major role in carbohydrate metabolism, which establishes a link between magnesium and diabetes. Magnesium can influence the release of insulin, which in turn is responsible for controlling blood sugar (glucose) levels . People with diabetes tend to have lower magnesium levels, and it can either aggravate insulin resistance or be a consequence of insulin resistance. When the blood glucose levels go high, the kidneys lose their ability to retain magnesium, leading to excess excretion of magnesium in the urine. The loss of magnesium in this way leads to low levels in the blood, called hypomagnesemia. Also, insulin resistance decreases the cellular uptake of magnesium and therefore the intercellular levels become too low.
Two studies – the Nurses’ Health Study (NHS) and the Health Professionals’ Follow-up Study (HFS) [4,5] – monitored over 170,000 health professionals through questionnaires. In addition to evaluating diet, dietary supplement and multivitamin information was also collected. To examine the link between magnesium and diabetes, over 127,000 participants (with a female-to-male ratio of roughly 2-1) with no history of diabetes, heart disease or cancer were monitored. It was observed that the risk of developing type 2 diabetes for men and women was greater where there was a lower intake of magnesium .
Another study called the Women’s Health Study also examined the link between magnesium and diabetes and noted that the risk of developing type 2 diabetes were significantly higher when the magnesium intakes were lower .
Aside from these observational studies, there have also been clinical studies to examine supplemental magnesium and diabetes, specifically the control of the disease. One of these studies had 63 subjects who had below normal serum magnesium levels (amount of magnesium in blood). They were given either a 2.5-gram dose of oral magnesium chloride (equivalent to 300 mg magnesium), or a placebo, on a daily basis. After the 16 weeks, those who received the supplemental magnesium showed improvements in their serum magnesium levels and exhibited significantly improved control of their diabetes. 
You could start by getting more magnesium through diet. Eat plenty of leafy greens and unrefined foods. However, if you are a diabetic on a restricted diet, you may find it hard to get the required amount of magnesium from your food. Oral magnesium supplements like Mag365 are the obvious choice for diabetics. Mag365 is a superior supplement with a very high amount of bioavailable magnesium. You can also try transdermal magnesium supplements like Magnesium Rub or Magnesium Gel as a medium for massage. Magnesium Rub is a sea water concentrate, with the sodium removed, and when applied directly to skin, it is absorbed quickly and has a calming effect on the nerves.
