Healthy bones

Healthy bones.

Muscle cells increase in volume, shrink, grow old and die, but multiplied in number. Bone behave differently. From birth to death, they constantly absorb different substances dissolve and thus reformed (by modifying the shape and size), so the cells that make bone, no time for aging. The process of formation prevails until late adolescence (absorption exceeds resorption), so the skeleton grows in size. During the early stages of adulthood weight of the skeleton remains more or less unchanged, and then, after about 40 years, resorption exceeds formation, resulting in a gradual decrease in total bone mass (this process is called osteoporosis) in 0,3-0,5 % per year. A man in his old age loses about 20-30% of skeletal mass, women - up to 50%. They have this process starts earlier and proceeds more rapidly. Men also must take into account this factor, as a result of osteoporosis increases the number of fractures in the elderly. Engage in exercises, spend on your feet for at least 3 hours a day and watch your diet. Bones, like muscles, are strengthened by exercise, and prolonged absence of loads atrophy. Unlike muscles, bones need only exercise with weight-bearing (swimming, for example, do not bring them any good). Bed rest can be catastrophic for the bones, especially the elderly. Studies have shown that patients stay in bed for 9 months, lost over this time bone mass, equivalent to an ordinary loss in 10 years. Being a relatively young and healthy in other respects, they restored the lost bone mass, but it also took 9 months. Exercises for people confined to bed, given some guidelines, strengthens muscles and improves blood circulation, but do not help the bones. Scientists discovered that astronauts in weightless conditions lose bone mass assigned to them by daily exercise, but they proved useless. The skeleton, like many other organs, normal functioning, only doing the work for which it was designed - support the body while resisting the force of gravity. This implies a vertical position of the body, in which men should be in a total of at least three hours a day to ensure adequate bone strength. However, even many young people do not comply with this important condition. During the debate over the bones and the diet comes to mind thinking about calcium. Of course, it is better to have healthy bones, which requires obtaining the appropriate amount of calcium. However, while calcium is a beneficial effect on some bone diseases, osteoporosis is not the case. Higher doses of calcium in their youth will not make bones stronger than usual, as well as excess calcium in the passive way of life does not slow down the natural loss of bone mass. Bone and calcium, are part of them, carry out another one, not structural, function in the body - they are the "acid buffers", therefore, likely to receive excessive amount of acid promotes more rapid dissolution of bone mass.

Citrus juices have little effect on the total content of acids in the body, the major adverse effect on the factors, there may be a diet high in protein and increased consumption of acidic phosphates - the main ingredient in soft drinks.

Dangers of Osteoporosis

Osteoporosis is insidious: a long time the disease is asymptomatic, does not manifesting itself. Sometimes the only manifestation - back pain with prolonged standing, which is reduced when a person takes a horizontal position. The most serious and typical consequence of osteoporosis is hip fracture, which often occurs in older people.

Symptoms of osteoporosis

Self-identify osteoporosis at an early stage is difficult. Alarm are nocturnal cramps in the legs and feet, bone pain, back pain, fractures of the femoral neck, spine, wrist or other parts of the skeleton, the widow's hump - the curvature of the spine forward, the decrease in growth (2-3 cm per year), the fragility or softening of the nails, premature graying
