Get Your Magnesium: Avoiding Type 2 Diabetes
We know that obesity is the single strongest risk factor for developing type 2 diabetes. That said, it also appears that eating certain foods helps to reduce the risk of type 2 diabetes. These foods, which include whole grains, beans, nuts, and fruits and vegetables, are all high in magnesium.
What is the right diet for people with diabetes?
Over the years there have been a number of different strategies for diabetic diets. For a long time diabetics were taught to use exchange lists, but a lot of people found it complicated and hard to use. More recently the training has focused on counting carbohydrates at each meal or snack. For diabetics who take insulin (Type 1 diabetics), carefully regulating when and what they eat is key and counting carbs in this way works well for them.
How to Exercise with Disabled or Weak Legs
Spending long hours sitting in a wheelchair or in a bed can not only be uncomfortable, but can also lead to weight gain, weakened muscles, joint and muscle stiffness and weakened heart and lungs. Thus, moving as much as possible is very important for anyone with disabled or weak legs.

It's all too common to see a loss of skeletal muscle mass in the elderly, a condition known as sarcopenia. It's a strong risk factor for both disability and mortality. We also know, from studies in the young, that magnesium supplementation can help increase muscle strength, and that the elderly tend to be magnesium-deficient. Scientists in Palermo, Italy wondered if the two, magnesium deficiency and muscle strength, might be related in the elderly as well as the young (Am J Clin Nutr 2006;84(2):419-26).
To find out, a team from the Department of Internal Medicine and Geriatrics at the University of Palermo recruited 1,138 men and women, of whom 77% were over 65 years of age. None of the participants had kidney disease, cognitive impairment, or hypercalcemia (overly high blood calcium levels). Their Body Mass Index, level of exercise, muscle area, and muscle density were recorded, along with age and sex, as variables.
Each participant's strength was tested at four different points: handgrip strength, knee extension, single leg extension, and ankle extension, and their blood was tested for serum magnesium levels.
Even after adjusting for age, sex, and BMI, the researchers found that physical strength was highly correlated with serum magnesium levels: the stronger the subject, the higher the blood levels of magnesium.
The typical Western diet is often magnesium-deficient, and other studies have shown that magnesium intake decreases with age. Magnesium deficiency can also cause irregular heartbeats. The Recommended Daily Allowance of magnesium is 320mg for women and 400mg for men. Make sure you're getting enough magnesium in your diet by referring to this list of foods containing magnesium.
