Calcium, Osteoarthritis & Osteoporosis
American women have 3 times the calcium as Asian women and twice the amount of Osteoarthritis
This article will serve as an example why whole plant nutrient and/or supplements are the only sensible health choice and these alone give the body a balance spectrum of nutrients it needs to do the job of repairing and building.

Osteoarthritis (OA) also known as degenerative arthritis or degenerative joint disease is a group of mechanical abnormalities involving degradation of joints, including articular cartilage and subchondral bone. Symptoms may include joint pain, tenderness, stiffness, locking, and sometimes an effusion. A variety of causes—hereditary, developmental, metabolic, and mechanical—may initiate processes leading to loss of cartilage. When bone surfaces become less well protected by cartilage, bone may be exposed and damaged. As a result of decreased movement secondary to pain, regional muscles may atrophy, and ligaments may become more lax.
Treatment generally involves a combination of exercise, lifestyle modification and analgesics. If pain becomes debilitating joint replacement surgery may be used to improve the quality of life. OA is the most common form of arthritis, and the leading cause of chronic disability in the United States. It affects about 8 million people in the United Kingdom and nearly 27 million people in the United States. Wikipedia
More than 28 million Americans are at risk for osteoporosis, and more than 10 million already have been diagnosed with this bone-degenerating disease. Women make up an astounding 80 percent of those who are affected by osteoporosis. Though most people associate osteoporosis with older people, the disease strikes young and old alike. But osteoporosis does become much more common as you age -- affecting one in two women over age 50. How stuff works
The IOM finds that the evidence supports a role for vitamin D and calcium in bone health but not in other health conditions. Further, emerging evidence indicates that too much of these nutrients may be harmful, challenging the concept that “more is better.” Institute of Medicine
A report today from the influential Institute of Medicine sets the first formal recommendations for daily intakes of calcium and vitamin D for bone health, and suggests that most people are getting what they need.
According to the report, children and adults younger than 71 need no more than 600 international units (IUs) of vitamin D a day and should consume 700 to 1,300 milligrams of calcium a day, depending on their age.
Among the reasons for sufficient intakes: food fortification and more supplement use. Many foods, such as milk and yogurt products, are rich in calcium and fortified with vitamin D. Fatty fish such as salmon, mackerel and tuna also have a lot of vitamin D.

Calcium is essential to bone health, however, it is extremely important not to overlook the other vital nutrients which synergistically promote the maintenance of healthy bone tissue. For instance, megadoses of calcium, in the absence of other minerals such as magnesium, may contribute to abnormal soft tissue calcification. Recent research is showing that magnesium is at least as important as calcium in preventing osteoporosis. Oral supplementation with as much magnesium as calcium helps to prevent bone loss and increase the re-mineralization of weight-bearing, trabecular bone in post-menopausal osteoporotic women (Makgoba NW Datta HK. Eur J Clin Invest. 1992;22:692-696; Abraham GE Grewal H. A total dietary program emphasizing magnesium instead of calcium. J Repro Med. 1990;35:503-507). (Calcium supplementation mostly increases the mineral density of non-weight bearing, cortical bone). Magnesium deficiency is common in patients with osteoporosis (Werbach MR, Nutritional Influences on Illness 1987. Keats Publ. New Canaan, Conn., p. 339; Cohen, L Kitzes R. Israel J Med Sci 1981;17:1123-1125).
This idea of synergistic bone nutrition is reiterated with reports of possible adverse effects from supplementing ONLY calcium in celiac patients, which, "may have exacerbated marginal deficiencies of magnesium, zinc, manganese, or other minerals that are needed to maintain bone mass", since celiac patients have decreased absorption and have multiple nutritional deficiences (Mautalen C. et al. Am J Gastroenterol 1997;92:313-318). As a supplement choice, veal bone meal is approximately 55% magnesium, and includes trace minerals such as zinc and manganese. How convenient that nature provides such a balanced supply of nutrients for bone health!
Phytoestrogens (plant phytochemicals that demonstrate weak estrogenic activity), can contribute to proper bone growth and maintenance. "Phytoestrogens are potentially important in the prevention of postmenopausal osteoporosis caused by estrogen deficiency" (Draper C et al. J of Nutr 1997;127:1795-1799). Phytoestrogens can increase estrogen when levels are low, and also prevent exceedingly high levels by occupying estrogen receptors. Phytoestrogens are found in high quantities in soy (of all foods, tofu contains the greatest amounts of isoflavones), and in the herbs dong quai and black cohosh (black cohosh is contraindicated in pregnancy). The isoflavones may have a direct effect on bone health by inhibiting bone loss (Brandi ML Bone and Mineral 1992;19(Suppl):S3-S14). The herbs ginseng and horsetail can increase estrogen levels and are recommended for women at menopause (Ojeda, L. Menopause without medicine. Hunter House Inc. 1995). Wild yam does not contain progesterone, however it does contain diosgenin, which is a precursor to progesterone. While estrogen mainly prevents bone loss, or osteoclast activity, progesterone stimulates bone growth, or osteoblast activity (Lee J. MD. Natural Progesterone: The multiple roles of a remarkable hormone. BLL Publ. Sebastopol CA 1993). nutri-notes.com
