Osteoporosis happens as we age, but certain factors accelerate the process. The foods we eat can leach calcium from our bones such as high-sugar, high animal protein, refined grains, coffee, sodas, alcohol, high sodium diet and tobacco. Various pharmaceuticals such as steroids and gastrointestinal medication can disrupt our calcium levels as well. A higher risk for osteoporosis exists for women, older adults, people with small frames, a family history of hormone imbalances in the thyroid or adrenals, smokers, coffee drinkers, or those who have a sedentary lifestyle.
In one study, it was found that “eliminating meat from the diet cuts the urinary calcium loss in half. Cutting sodium intake by half can reduce calcium requirements by 160 mg per day.” The more protein that is taken in, the more calcium that is lost.
The Physicians Committee for Responsible Medicine (PCRM) reports, “The average calcium intake in Singapore is 389 mg/day, less than half of the recommended daily allowance in the U.S. Yet the fracture rate in Singapore is five times lower than that of the U.S., where the calcium intake is much higher.”
Despite clear scientific proof that calcium is not the answer to osteoporosis, in January 1997, a new advertising campaign promoting milk consumption was launched, sponsored by the National Fluid Milk Processor Promotion Board. The PCRM lodged a complaint with the Federal Trade Commission in Washington, DC, pointing out that, “Increasing milk consumption is one of the weakest possible strategies for protecting the bones and to suggest otherwise is dangerously misleading.”
Bone density machines can help determine the mineral density of your bones. But, in general, it is a good idea to support your bone health as you age regardless.
Here are 3 ways to help support your bone health:
1. Calcium. Calcium is crucial for strong, healthy bones. Not all calcium supplements are equal and some use forms of calcium not easily absorbed by the body. Instead, try adding in calcium rich foods such as leafy greens- bok choy, broccoli, collards, Chinese cabbage and kale. These have greater bioavailability than the calcium found in milk. Spinach, although high in calcium, is not a good source of calcium because the calcium binds to oxalates and is therefore poorly absorbed. Decrease your risk of osteoporosis by restricting animal protein, salt and smoking, while flooding the body with calcium from vegetable sources, along with the proper enzymes to lodge this calcium in the bones.
According to the vegan society, if protein intake is inadequate, (less than 0.8 g of protein per kg of body weight), the body lacks the building blocks for muscle and bone, and growth hormones which stimulate muscle and bone building will decline to undesirable levels. Consuming less than the recommended amount of protein in order to reduce calcium loss is not the correct approach. Individuals with a low calorie intake are particularly at risk of getting insufficient protein.
The choice of protein source can make a great deal of difference. A person trying to increase protein intake using meat or fish will lose 25 mg of calcium from their body for every 100 g eaten. In contrast, a 100 g portion of beans (by dry weight) has an approximately neutral effect on calcium balance while providing the same amount of protein.
2. Trace minerals. Our food supply does not contain the rich mineral content it did 50 years ago. Modern agricultural practices have stripped the soil of its nutrients, leaving the foods we eat in a less nutritious state. Trace minerals provide a broad spectrum of minerals that we need to maintain optimal health.
3. Essential Fatty Acids. The omega oils help lubricate joints and reduce inflammation in the tissue and muscle surrounding our bones. Eat more wild caught non-farm raised fish, olive and flaxseed oils, nuts, and leafy green vegetables.
4. Exercise. Exercise can help build strong bones and slow down bone loss. It is best to have a consistent exercise regimen throughout your life, rather than exercising in small bursts. Alternate strength training with resistance exercise. Always check in with your doctor before beginning an exercise routine.
5. Vitamin D. Vitamin D is an essential nutrient for bone health. Because of our modern lifestyles, we do not get the proper amounts of vitamin D from our environment. Twenty minutes of sun exposure will give you the boost you need, however, when sun exposure is not possible, talk to your Naturopathic Doctor about ways to supplement Vitamin D in your diet.
