Are you Becoming “Bone Brittle”

By Caroline Smith

You’re exercising and feel a slight pain in your shin or foot. You keep going figuring it will get better. When the pain progresses and affects your workout, you decide to see medical assistance. Upon a doctor’s evaluation you are told you have a stress fracture. You find this hard to fathom as there was not direct trauma to the area that you can recall.

Your program is reviewed and it is appears you exercise regularly-including stretching, buying new shoes frequently, and eating a reasonable diet. It appears most dairy products have been eliminated from your diet, since you felt it was the culprit in mucous development in your throat (research now indicates that the mucous could be due to wheat, other food intolerances or an incorrect balance of the protein, carbohydrate and fat ratio). You may be experiencing osteoporosis.

Since dairy products are touted as the most common food group for obtaining dietary calcium, elimination of them could potentially lead to some serious physical problems. Calcium is necessary for the maintenance of healthy bones and teeth. It keeps the heart beating regularly, helps to alleviate insomnia, assists the body in its metabolism of iron and aids your nervous system in impulse transmission. There are other foods that provide calcium (see the chart at the bottom of the article) and bringing some of these sources into your diet can be helpful. Sugar or an acidic pH will leach calcium from the bones and drinking a lot of soda pop can lead to problems.

Our bones are in a constant state of change, a process known as remolding. This is where small quantities of old bones are lost through resorption (broken down and absorbed) while at the same time new bone formation occurs. When the formation of bone does not keep pace with its resorption it is termed osteoporosis.

Osteoporosis, “porous bones”, afflicts an estimated 24 million Americans and contributes to over one million fractures per year. It is more commonly noted in the older, white, fair skin, small framed female population and those who smoke. Other risk factors which increase a women’s chance of getting osteoporosis are: alcoholism, sedentary lifestyle, childlessness, diabetes mellitus, low calcium intake, high protein intake, high phosphorous intake and/or a family history of the problem.

If you fall into several of these categories, you need to consider taking measures to slow the process. Although there is not a cure there are three options for treatment which have been successful. They are exercise, diet and hormone therapy.

EXERCISE

Within the exercise area it is interesting to note that osteoporosis is now becoming a problem with athletes possibly due to a reduction in calcium rich foods, low calorie diets in an effort to get lighter to race, or a decrease in the amount of impact aerobic activities being performed.

Since our bones develop their peak bone mass by the mid-20’s it is very important to fulfill the necessary calcium requirement through these important developmental years, and continue to meet the calcium needs as we grown older. After peak mass is met, the calcium that is loss is not completely replaced and over time the bone density diminishes. As a matter of fact by the time we are 60 years of age most women have only three-quarters of the bone mass they had in earlier years.

Exercise stimulates the activity of the osteoblasts, the cells that make the bone, while slowing the development of the osteoclasts, the cells that break down the bone. Impact aerobic activities helps to keep the bones dense due to the weight bearing stresses to the bone itself. In addition, the development of muscle can better protect the bone in the case of a new fall.

DIET

How much is enough? The new RDA (recommended dietary allowances), printed in 1989, estimates that the absorption rate is about 40% and has derived 1200mg for both sexes ages 11-24 as the guideline. For the older population the previous allowance of 800mg is retained. The amount of calcium can easily be obtained if dairy products are included in the diet. If you are a Blood Type O or A these may not be your best choices as undigested foods leads to other health issues. Other food sources for obtaining calcium are: soybeans, sardines, salmon, peanuts, walnuts, sunflower seeds, dried beans, green vegetables and calcium fortified orange juice. A balanced diet will not only furnish calcium but other nutrients essential for good bone health. Should osteoporosis be a health issue, these guidelines many not be sufficient and it is best to seek medical attention.

HORMONE THERAPY

The final are of concern is postmenopausal women. The rate of decline in bone mineral is strongly dependent on estrogen status. The estrogen slows the rate of bone loss. The research by NRC (National Research Council) in 1989 found minced evidence that supplementary calcium (1.5 to 2.5g/day) could retard the rate of post-menopausal bone loss. The research indicated that calcium alone has only a small effect on bone loss but the combination of estrogen and calcium plus regular exercise is an effective treatment. In addition, supplementing Vitamin D in the tocopherol form can make a big difference in the regulation of the calcium in the body. Vitamin D deficiencies have been linked to many health issues besides osteoporosis. If you live in a cloudy climate during the winter months taking 1-3,000IU of Vitamin D can help stabilize the body. Research has shown doses as high as 10,000 IU in severe health imbalances. I recommend my clients have their D status tested in their blood workups and then we test the appropriate form and amount on the BodyScan machine.

The area of osteoporosis has been one of multiple studies in the past few years due to the large number of Americans affected. It is a crippling bone disease which can be managed through a proper exercise program and a sufficient dietary intake of calcium. These two factors can go a long way in contribution to healthy bones throughout life. If hormone therapy becomes a consideration, weigh all the advantages and disadvantages and include the above options for protecting the bone loss into your health plan.
