magnesium in de voeding en supplementen in belangrijk voor een goede botopbouw.
Dit blijkt uit een studie onder 2.000 ouderen van 70-79 jaar. De meeste mensen
bleken veel minder magnesium in te nemen dan de dagelijks aanbevolen
hoeveelheden. Bovendien bleek dat voor iedere extra 100 mg inname per dag nam de
botdichtheid met 1% toe.

In Your Diet Could Lead To Stronger Bones

of magnesium through diet and supplements is positively associated with bone
density throughout the whole body, particularly in older white adults, according
to research published in the Journal of the American Geriatrics Society.
Researchers say the effects are similar to that of calcium.
Over 2,000 black and white men and women ages 70-79 years old were asked to
complete a questionnaire to determine how much magnesium they were receiving
from food and various supplements. Additionally, researchers performed bone
mineral density tests on the participants.
The study revealed that those who ingested more magnesium had significantly
higher bone density than those who got the least amount of magnesium. For every
100 milligram per day increase in magnesium intake, data showed a 1% increase in
bone density.
However, this link was only true for the older white men and women. Previous
research has demonstrated that black men and women may process vitamin D and
other calcium regulating hormones differently than whites, thus possibly
explaining the lack of association between magnesium and bone density among them
in this study.
"Although this [1% increase] seems small, increases across a population may
have large public health impact," states lead researcher Kathryn M. Ryder.
The recommended daily allowance of magnesium is 320 mg/day for women and 420/mg
day for men in this age group. Most people in this age group get far less than
this daily amount.

Lead researcher Kathryn M. Ryder, MD, MS is available for questions and
interviews and can be reached at kryder@utmem.edu. She is currently affiliated
with the University of Tennessee Health Science Center, Departments of Medicine
and Preventive Medicine. Dr. Ryder is currently running a study of 75 men and
women over the age of 55 which will be the largest randomized double-blind
placebo controlled study of the impact of magnesium on bone formation and loss.
