Explanation:
Osteoporosis
Osteoporosis is one of the most common problems among older Americans. It is the primary cause of “shrinkage” in stature and bone fractures among the elderly. Starting in the 20’s for women and somewhat later for men, calcium is gradually lost from the bones. It results in a shortening and weakening of the long bones and greatly increases a woman’s susceptibility to fractures. This loss of calcium accelerates in women after menopause. Past 50 years of age, 25 to 30% of women and 15 to 20% of men suffer a shortening of the spinal column as a result of osteoporosis.
Osteoporosis afflicts one in four American women past menopause. It causes a loss of height with age because spinal vertebrae collapse, producing the characteristic “dowager’s hump.” Osteoporosis is the primary cause of debilitating hip and wrist fractures that commonly afflict older women. It also may be a factor in bone loss in the jaws; it leads ultimately to a loss of teeth through periodontal disease.
Women who are three to six years past menopause can help prevent bone loss by increasing their calcium intake in addition to getting plenty of exercise. While large amounts of calcium supplements are used by older women, the evidence shows that such supplements can prevent or stem the progress of osteoporosis in some people, but not all. Dietary calcium (calcium from foods) is much better absorbed and used by the body than supplements. However, no supplement can replace calcium already lost from bones; at best, it can slow down further deterioration. Thus, prevention is so important.
Fluoride also is important to bone strength. Osteoporosis is significantly less common in communities serviced by fluoridated water; this suggests that fluoride protects against the disease and the fractures that accompany it. Fluoride combines with the calcium in the bone and helps to prevent the loss of calcium common after mid-life.
Other factors, besides the amount of calcium consumed, influence how much of this mineral is absorbed by the body. The following is a partial list.
Vitamin D in an active form is needed for calcium to be absorbed through the intestinal tract; older adults make less of this active form of vitamin D.
Vitamin C improves calcium absorption, as does lactose (milk sugar).
Eating too much protein or fat interferes with calcium absorption; it greatly increases the amount of calcium the body loses.
Inactivity speeds the loss of calcium; physical exercise throughout life helps prevent bone loss with age.
Some foods contain substances that bind up calcium these foods contain in a way that prevents the mineral’s absorption. These substances include:
oxalic acid in spinach, chard, beet greens, and rhubarb; and
phytic acid in the bran of whole grains.
However, such binding is not thought to interfere seriously with the amounts of calcium the body obtains.
Excess phosphorus can increase the need for calcium and, thus, create a shortage even though there is an adequate amount of calcium in the diet. This may be a problem among adults who consume little or no milk products or among teenagers who drink too much soda pop (rich in phosphorus).
Loss of estrogen at menopause greatly accelerates the loss of calcium from a woman’s bones.

Answer:
When someone is undereating ,they are consuming fewer calories than their body needs to function correctly. This can have a severe impact on energy levels, causing feelings of physical tiredness and mental fatigue, which may impair a person's daily functioning
