Calcium

CALCIUM
Calcium is a major mineral constituent of teeth and bones. In addition to dairy products, green leafy vegetables such as collards, kale, and turnip greens, as well as beans, sea vegetables, seeds and nuts, and other plant quality foods are high in this mineral. Current medical research suggests that calcium from animal sources is processed differently in the body than that from plant sources. The relation between dietary calcium and the calcium in bones appears to be the result of many synergetic factors, so that simply taking in more calcium, especially from dairy products and calcium supplements, may not strengthen the skeletal structure and, in fact, may weaken it. See Dental Health, Kale, Osteoporosis, Protein, Vitamin D.

• Calcium Intake Unrelated to Bone Development - Calcium intake is not linked to strong bones, according to British researchers. In a study of mothers in England and Gambia, scientists found that the Africans, who ate a diet low in calcium and had as many as ten babies and breast-fed each one, had comparable bone masses as English mothers who ate a high calcium diet and had had on average two children and breast-fed them little or not at all. The researchers found that the En-glish women on a high-calcium diet, from dairy foods, were more likely to get osteoporosis later in life than the Gambians. Calcium supplements proved useless in boosting the bone mass of women of childbearing age.

Arthritis

ARTHRITIS
Arthritis, a painful bone and joint disease, affects millions of people. Major forms include osteoarthritis, the painful hardening of bones and joints in the hands or spine, which affects primarily older people, especially men. Rheumatoid arthritis, involving the inflammation and swelling of the joints, especially in the hands and feet, appears primarily in women aged 25 to 50. A balanced diet has benefited some people with arthritis. Excessive animal food and salt appear to be connected with osteoarthritis, while potatoes, tomatoes, and other nightshade plants have been associated with rheumatoid arthritis. See Fibromyalgia, Fish, Lupus, Nightshades, Sesame, Vegetarian Diet.

• Macrobiotic Approach - The macrobiotic approach to arthritis, including a classification of the different types of arthritis, dietary guidelines, home cares, and case histories, is included in several books devoted to this subject. Some arthritis is believed to be caused by strong animal food intake, especially chicken and eggs, while another type is associated with tropical fruits and vegetables, especially nightshades.

• Low-Fat Diet Relieves Rheumatoid Arthritis - Fat-free diets have produced complete remissions in six patients with rheumatoid arthritis. Doc- tors at Wayne State University in Detroit reported that when a low-calorie, low-fat diet in which chicken, cheese, safflower oil, beef, and coconut oil were eliminated, stiffness and swelling of joints disappeared within days. Patients remained symptom free for up to fourteen months, only to experience short-term recurrences within usually 24 to 48 hours of eating foods which were high in fat. “We conclude that dietary fats in amounts normally eaten in the American diet cause the inflammatory joint changes seen in rheumatoid arthritis.”

• High-Fat, High- Sucrose Diet Contributes to Arthritis - In laboratory experiments, rats fed a diet high in fat and sucrose developed abnormal stiffness, reduced energy, and other adverse morphological and structural changes.

• Vegan Diet Helps Arthritis Patients - In a study of 43 patients with rheumatoid arthritis, researchers reported that those assigned to a vegan diet rich in lactobacilli had changes in fecal microbial flora associated with improvement in rheumatoid arthritis activity.

• Arthritic Patients Improve on a Vegetarian Diet - In a case control study, rheumatoid arthritis patients assigned to a vegetarian diet had a significant decrease in platelet count, leukocyte count, calprotectin, total IgG, IgM rheumatoid factor, and other biochemical and immunological variables compared to those assigned to an omnivore diet. The researchers concluded that “dietary treatment can reduce the disease activity in some patients with rheumatoid arthritis.”
