Foods for Enhancing Bone Density
As part of a diet for strong
bones, and for your
health in general, you need
to eat a healthy, well
balanced and varied diet that includes at least 5
servings of fruit and/or vegetables a day, plenty of wholegrain cereals and not
too much sugar or fat. Building strong
bones when we are young and helps to
reduce the effects of bone-density loss as we get older means that we can
alleviate many of the symptoms of
Research has shown that a poor diet increases the risk of osteoporosis later in
life. As we have seen, bones are made up of a thick outer shell with a strong,
dense inner mesh that has a honeycomb-like structure. A good calcium intake is
vital because this gives the bones their strength and rigidity. As bone becomes
old it is vital because this gives the bones their strength and rigidity. As
bone becomes old it is removed by the body and replaced with new bone – it has
been calculated that adults replace their entire skeletons every seven to 10
years. Calcium, therefore, gets deposited and withdrawn from the skeleton on a
daily basis. As we get older, this renewal process slows down and bone-density
loss increases. When this happens, the holes in the bone’s inner mesh gradually
become bigger and the bones become more fragile. However, by maximizing bone
mass early in life and by maintaining a
healthy diet, we can reduce the effects
of this process.
In a study to be published in The Endocrine Society’s
Journal of Clinical Endocrinology & Metabolism, researchers found that
diets high in protein and cereal grains increase calcium excretion and can
weaken your bones while a diet high in fruits and vegetables actually
Onions: Several studies since 2005 show
that Onions slow the resorption of
bone. (That is the break down of old bone by our Osteoclasts. One of the reasons
why many people develop Osteopenia or Osteoporosis as they age is that our bone
building cells (Osteoblasts) slow down after age 33 -35 but our Osteoclast
cells, that remove old bone, keep working at the same level. As our bodies are
remove more bone that they build, we soon develop thin or porous bones. Onions slow the removal of bone. It seems the silicon
content in Onions might be helping in building new bone. Silicon is necessary
for turning your calcium into bone.
Prunes: They are top
osteoporosis beaters. They contain a fibre called inulin, which
facilitates better calcium absorption, so strengthening your bones and warding
arthritis. Four a day will keep you in plum (ouch) condition.
Banana: Banana contains your entire RDA of potassium, an electrolyte
that prevents the loss of calcium and therefore maintains good bone-strength.
They also bolster the nervous system, boost
immune function, and
help the body metabolize protein.
Broccoli: The floret is full
iron, and a particularly high concentration
vitamin C, which is vital in creating the optimal bone matrix for overall
skeletal strength. 200g a day will do the magic, and you can use cauliflower,
kale, brussels sprouts and cabbage for variety, as they all possess many of the
same qualities. In addition to calcium, magnesium is just as important for
maintaining strong bones. In a Health, Aging and Body Composition study of 2,038
elderly men and women, the more magnesium they consumed, the higher their bone
density (among white men and women).
Leeks: packed with
a B-vitamin that studies have shown reduces homocystein, an amino acid that
weakens the bones and also makes heart attacks more likely.
Oysters: They are a source of
the zinc necessary to form the basic bone structure of collagen.
Walnuts: Separate animal studies have found that omega-3 fatty acids
may add density to bones and promote bone formation. Dr. Chaim Vanek and Dr.
William E. Connor from the Oregon Health and Science University said the Swedish
study “adds to a growing body of evidence that omega-3 fatty acids are also
beneficial to bone health.” Some excellent food sources of
omega-3 fatty acids
are walnuts, salmon, and flaxseeds.
Kiwis: Like bananas they are
high in bone-protecting potassium. Try to eat at least one or two a week. Don't
peel the skin - it's edible and packed with extra
nutrients. Put up with your
which reinforces bone-mineral density. Spinach is also high in
bone-friendly calcium, phosphorus, potassium and zinc, as well as selenium,
which protects the liver and helps make the risk of Alzheimer.
Twenty minutes of
sunshine each day helps
to prevent a
vitamin D deficiency. Among its many functions, vitamin D
facilitates the absorption of calcium and phosphorous, and helps regulates
normal calcification of the bones.
Be Careful with….
Protein: High intakes of protein increase the excretion of calcium in the urine.
For most people, however, protein intakes are not high enough to give cause for
concern, but it could be a problem if you take protein supplements or follow a
high protein, weight-reducing diet.
Salt: High sodium (salt) intake can also increase the loss of calcium in the
urine. Over three quarters of the sodium in our diet comes from processed foods,
so the simplest way to reduce sodium intake is to eat fewer processed foods.
Food with less salt may initially taste bland, but by gradually reducing the
amount of salt you eat, the tastebuds will adapt as the salt receptors on the
tongue become more sensitive. Try using other flavourings such as herbs and
spices, lemon or mustard.
Caffeine: High intakes of caffeine can reduce absorption of calcium each cup of
coffee prevents the absorption of 6 mg of calcium, which is the amount you would
get from 1 teaspoon of milk. The effect of caffeine is relatively small, but
people with very high intakes should cut back.
Alcohol: Excessive intakes of alcohol
can damage the cells that make new bone. If
you drink, stay within the recommended guidelines (no more than 2-3 units of
alcohol a day for women).
Fizzy drinks: Phosphate, in the form of phosphoric acid, is used as a
preservative in most canned fizzy drinks. When phosphorus levels exceed calcium
levels in the blood, the body responds by stimulating bone breakdown to release
calcium into the blood. Although there is no hard scientific evidence to show a
detrimental effect on bone health, it is probably wise to cut back if you have
an excessive intake, and to limit the amount of fizzy drinks your children
consume. Instead, why not offer a glass of cold milk?
