A higher intake of magnesium from
food and supplements may keep bones healthy as people
age, according to results of a study in Journal of the
American Geriatrics Society which suggests that greater
magnesium intake is significantly related to higher bone
mineral density (BMD) in white men and women.
According to the paper, there was an approximate
2 percent increase in whole-body BMD for every 100 milligram
per day increase in magnesium.
"Higher magnesium intake through dietary change or supplementation
may provide an additional strategy for the prevention
of osteoporosis," researchers conclude.
Osteoporotic fractures are a significant health problem
in aging adults, Dr. Kathryn M. Ryder, of the University
of Tennessee, Memphis, and colleagues note in their report.
Given the high prevalence of low BMD and fracture, small
improvements in BMD may have a large public health effect,
Magnesium is a "lesser-studied" component of bone that
may play a role in calcium metabolism and bone strength,
they add.
Ryder's group examined magnesium intake from supplemental
and dietary sources in relation to BMD in a total of 2038
black and white subjects between the ages of 70 and 79
years enrolled in the cross-sectional Health, Aging, and
Body Composition Study.
They used a semiquantitative food frequency questionnaire
to assess dietary intake of magnesium and standard tests
to measure BMD.
Less than 26 percent of the study sample met the RDA
for magnesium, the investigators report.
White and black women reported a similar intake of food
magnesium, but because of more frequent magnesium-containing
supplement use, white women had a higher total mean intake.
Compared to black men, white men reported higher food
magnesium, use of magnesium-containing supplements, and
total magnesium intake.
After multivariate adjustment, magnesium intake was positively
associated with BMD in white, but not black, men and women.
The lack of an association in black men and women may
be due to differences in calcium regulation or in nutrient
reporting, the researchers suggest.

Build Better Bones - Bone exercise
monitor is introduced
(NEWTEST OY, Oulu, Finland) has developed and patented a
new NEWTEST BONE EXERCISE MONITOR. The product is designed
for 30 – 50 year-old women who are interested in their
health and well being and especially bone health. The Newtest
Bone Exercise Monitor offers an excellent tool for these
women to personally monitor and evaluate the effectiveness
of their bone exercise.
The monitor is designed for 30 – 50 year-old women
who are interested in their health and well being and
especially bone health (in EU, there are 68 million 30
- 49 year-old women). The Newtest Bone Exercise Monitor
offers an excellent tool for these women to personally
monitor and evaluate the effectiveness of their bone exercise.
Osteoporosis is a serious national health threat and
burden on national health and economy in most industrialized
countries. It is estimated that every other woman and
every forth man over age of 50 will suffer from osteoporotic
fracture. It is estimated that osteoporosis is suffered
by over 75 million people in EU, USA and Japan. There
is a great demand for new methods and tools to counter-attack
this vast health problem.
Good news is that osteoporosis can be prevented and its
impact reduced significantly. Bone exercise is one the
things one must consider when looking for ways to prevent
osteoporosis. Newtest Bone Exercise Monitor shows the
person using it if she has engaged in physical activities
that may have been helpful in strengthening her bones.
Newtest Bone Exercise Monitor is a small device worn
on the hip. The monitor measures and analyzes the user’s
physical activity in real-time and shows how many percentage
of the required daily bone exercise is achieved in very
easy-to-understand format.
Newtest Bone Exercise Monitor is also a new tool for
physicians, physical therapists and fitness instructors
as it offers a new method to follow up, instruct and motivate
women to engage in bone exercise. The monitor is also
a tool for the specialists in helping their clients to
achieve their bone health goals.
Newtest Bone Exercise Monitor is a first of kind product
in the world! It is based on the patented innovations
by the Newtest Oy. The Bone Exercise Monitor has been
used in award winning bone exercise research conducted
by the Medical School of Oulu University and Oulu Deaconess
Institute (Aki Vainionpää, Young Scientist Award,
European Calcified Tissue Society (ECTS), Nice and Timo
Jämsä, Clinical Biomechanics Award 2004, European
Society for Biomechanics).
