Pineapple and pineapple juice help to protect against osteoporosis and strengthen bones. Pineapple contains the microelement manganese. Manganese, like boron, is involved in the metabolism of bones and promotes bone strengthening. In animal experiments, manganese deficiency led to a severe osteoporosis. Osteoporotic women been found to have three times less manganese in their blood than healthy women. The manganese in pineapple is easily absorbed. Foods, like spinach, beans, nuts, oatmeal, cranberries, raspberries, currants and cocoa, are rich in manganese too. Inclusion of these foods in the menu, will strengthen bones and support osteoporosis prevention.

Unfortunately, most of us get only half of the required amount of boron. This is insufficient to promote strong bones and prevent osteoporosis. Boron is found in fruits, especially in apples, pears, figs, grapes and peaches. It is also found in nuts (almonds, waln nuts, peanuts), in legumes, and in soy and honey. Probably due to boron deficiency, people who eat an inbalance of dairy products are prone to have osteoporosis. Vegetarians suffer less from osteoporosis because their diets are rich in fruits and nuts.
Pineapple - osteoporosis prevention!
Helpful to bones - foods that are high in calcium, nuts, fruits, (especially pineapple juice) and vitamin D.
Harmful to bones - an excess of caffeine, salt and alcohol.
Calcium - osteoporosis protection
After menopause, women should intake 900-1000 mg of calcium per day to promote bone health and prevent osteoporosis. A large intake of calcium cannot change the genetic predisposition for osteoporosis. It can, however, correct calcium deficiency and reduce the risk of bone fracture. The best known source of calcium is dairy. If diet restrictions preclude milk, there are other sources of calcium, such as canned fish (including bones), green vegetables (especially cole), and tofu (bean curd). The body does not absorb calcium without vitamin D. With a deficiency of vitamin D, bones weaken and fracture risk increases. New Zealand scientists found that women, who took vitamin D for 2-3 years, were less likely to suffer from fractures than those who took only calcium. Fat fish is a great source of vitamin D. In winter, the assimilation of vitamin D is reduced, and in the spring and summer, the sun increases it's level.
Salt steals calcium. Excessive salt is associated with destruction of bones. It washes away calcium and increases risk of fracture, especially in the elderly. Researchers found that a heavy salt diet will leach out 30% more calcium from the body. This is especially dangerous for elderly women, who have a higher risk of osteoporosis and bone fracture. For osteoporosis prevention, use salt in moderation.
About coffee. Coffeine contributes to osteoporosis. A detailed study of middle-age women, found, that drinking more four cups of coffee per day, increased the risk of hip fracture three times, compared with those who drank less coffee.
Most often, osteoporosis afflicts the skeleton bones of postmenopausal women, who lose calcium, particularly in the lower limbs. Although less common, osteoporosis affects the male half of humanity as well. Everyone knows that calcium helps strengthen bones, and is thereby key to preventing osteoporosis. Though bone diseases may be due to genetic factors, a proper diet helps reduce the risk of osteoporosis. If there is a deficit of boron trace mineral, the body can not absorb calcium. With a shortage of boron in the diet, especially after menopause, women lose more calcium and magnesium. These two minerals strengthen bones, if there is sufficient boron in the diet.
Studies have shown, that by including only 3 grams of boron per day, calcium loss is reduced by 40%. This is very important for osteoporosis treatment and prevention.
Alcohol and osteoporosis. Scientists from the University of Pittsburg found that moderate alcohol intake (up to six glasses of alcohol per week), increases estrogen levels in postmenopausal women and protects against osteoporosis. Excessive consumption, however, does not improve estrogen levels and, to the contrary, harms bones. Consuming more than four servings per day of alcoholic beverages, increases the risk of hip fractures by seven times. A safe dose of alcohol for bones is about the same as that for health in general - no more than 1-2 glasses a day. Obviously, alcoholism isn't compatible with bone health and osteoporosis prevention.
