This important mineral helps the activity of vitamin D in promoting calcium absorption. Osteoporosis sufferers are frequently low in zinc. Good sources arc oysters, fish, animal foods, pumpkin seeds and eggs.
We need some phosphorus to help make bone. But most of us have far too much of it, which upsets the calcium chemistry in the body. Excess phosphorus in the bloodstream sends a message that more calcium is required and stores are released from the bones. Some scientists believe that getting the calcium/phosphorus ratio right is more important than calcium alone in protecting bones. Nowadays it’s very easy to consume far too much phosphorus. It’s there in all kinds of food – instant soups and puddings, meat, cheese, toppings, cola drinks and fizzy drinks. Cut down on all of these. The ideal balance is equal parts of calcium to phosphorus. But research suggests we consume four times as much phosphorus as calcium. Cottage cheese, for instance, contains far more phosphorus than calcium.
Diets deficient in vitamin B6 produced osteoporosis in rats. It appears to increase the strength of connective tissue in bone. You can find vitamin B6 in everyday foods such as whole-grains, fish, nuts, bananas and avocados.
Vitamin К is known primarily for its effect on blood clotting. But it is also needed to synthesize osteocalcin, a unique protein found in large amounts in bone. Osteocalcin helps harden calcium, so vitamin К is vital for bone formation. In one study of sixteen osteoporosis patients blood levels of vitamin К were found to be 35 per cent lower than in healthy people of the same age. Frequent use of antibiotics can result in vitamin К deficiency. The best source is of vitamin К is green vegetables.
