LOW CALORIE DIETS/CANCER/LONGEVITY
Dr. Robert A. Good, president and director of Sloan-Kettering Cancer Center in New York reported that extensive investigations with laboratory animals have demonstrated that a low calorie diet reduces cancer risk and prolongs life. By restricting calories from the time of weaning, they were able to double or triple the lifespan of the experimental rats. Dr. Good emphasizes that the fact that for best results the caloric restriction must begin early in life.
The incidence of malignancies in the experimental animals, normally 90 percent in breeding females, and 60-80 percent in unbred females dropped to zero.
"Everything that I have ever really understood in these mice is directly applicable to man," says Dr. Good. "We already know that females who are extremely overweight have 8 to 10 times the incidence of endometrial cancer than females of normal weight."

ANALGESICS/DEMENTIA
Patients who use excessive amounts of pain medications containing phenacetin may develop an Alzheimer's disease-like dementia. The overuse of phenacetin may overpower the body's protective system, producing premature accumulation of lipofuscin (wear and tear pigment), and speeding neuronal aging.

BODY WEIGHT/LONGEVITY
Americans whose weight is at least 10 percent below the United States average appear to be lower risk of death than are heavier individuals. (Journal of the American Medical Association 257(3)353-358, January 16, 1987) Copyright Phylis Austin

EXERCISE/MENTAL FUNCTION/ELDERLY
Elderly people who are physically fit have higher fluid intelligence scores than sedentary peers. An Ontario, Canada study revealed that a 45-minute exercise period improved mental and cognitive (perception) function. Even light exercise was sufficient to induce this improvement.

SALT SENSITIVITY/AGING
People may become more salt sensitive as they age. Dr. Myron Weinberger, director of the hypertension research center at Indiana University, points out that sodium chloride (salt) restriction is very important in the treatment of high blood pressure in the elderly. He cautions that diuretic use may be dangerous in the older patient. (Medical World News 29(9)23, May 9, 1988) Copyright Phylis Austin

EXERCISE/AGING BRAIN
Regular physical exercise improves the mental ability of people from their mid-50s and on, according to a Scripps College of Claremont, California study.
A study of 300 people, aged 55-91 revealed that reasoning, reaction time, and memory tests improved with exercise. A significant difference was seen even in those who exercised for 30 minutes a day, but more exercise leads to better test scores. The researchers speculate that the benefits may be due to improvement in brain blood flow. (USA Today, June 21, 1989) Copyright Phylis Austin

BREEDING/LONGEVITY
A study on fruit flies conducted by Michael Rose, Ph.D., of the University of California at Irvine, suggests that delaying breeding may lead to a longer lifespan. Fruit flies in his studies lived 10 percent longer after 10 generations of delayed breeding; after 30 generations they lived 30 percent longer. Dr. Rose reported that not only did the fruit flies live longer, but they were healthier and more active longer into their lifespan. (Longevity 1(10)81, July, 1989) Copyright Phylis Austin

EXERCISE/AGED
Elderly people, even up to 96-years-of-age, have been shown to benefit from a high-intensity exercise program. A group of ten elderly persons in a nursing home placed on an exercise program demonstrated marked improvements in strength, walking speed, and mobility. Some of the people in the study group were able to discard their canes. They group demonstrated greater stability on their feet, and were less likely to suffer falls. The study showed increases in leg strength ranging from 61 to 374 percent over the study period. (Journal of the American Medical Association 263:3029-3034, June 13, 1990) Copyright Phylis Austin

EXERCISE/HEART DISEASE RISK IN ELDERLY
Leisure time exercise in elderly people has been shown to increase HDL cholesterol levels, and may reduce the risk of ischemic heart disease. (Journal of the American Geriatric Society 38:847-854, 1990) Apparently we are never too old to benefit from exercise. Retirement is a good opportunity to increase your exercise.

SUNLIGHT/SLEEP IN ELDERLY
Institutionalized elderly often have sleep problems, which are often treated with sleep medications, which often lose their effectiveness after a few weeks, and expose the patient to increased risk of falls, mental disturbances, and rebound insomnia.
A group of twelve elderly, demented men were placed out-of- doors in a brightly lit area twice a day, from 9-10 a.m. and again from 2-3 p.m. each day. There were no particular activities planned during the sun exposure time; patients who wished to sleep were allowed to do so. Some patients demonstrated improved sleep patterns the first night after sun exposure was begun. The men in the study slept more hours at night (and during the day) and their sleep was much more likely to be uninterrupted.
Earlier studies have demonstrated more sleep disturbances in blind individuals, suggesting that lack of sunlight may contribute to disturbed sleep.
Caretakers in the nursing home observed that the sun exposed men also demonstrated improved appetites, better bowel habits, increased attention spans and improved affect during the sun exposure.
Care should be taken that the patient not suffer sunburn during the exposure. Hats and sunscreen were utilized in this study.
The patients quickly returned to their poor sleep habits when the sun exposure was discontinued. (Journal of the American Academy of Physician Assistants 4:321-6, 1991) Copyright Phylis Austin

EXERCISE/MEMORY IN AGED
Memory in elderly individuals may be improved by a regular exercise program. A group of elderly individuals ranging in age from 61 to 83 years of age demonstrated improvement in verbal memory following a 9-week water aerobic exercise program.

EXERCISE/AGED
A group of veterans aged 65-74 were exercised three days a week for 90 minutes with warm up and cool downs, bicycling, strength development, and walking. Over the two year follow-up the participants demonstrated increased flexibility and improved cardiac function. (Journal of the American Geriatric Society 39:549-554, 1991) Even the elderly benefit from exercise! Another study revealed that exercised individuals demonstrated better cognitive function and sustained cerebral (brain) blood flow. (Inactive individuals suffer decreased brain blood flow).

BATHS/ITCHING/ELDERLY
Many elderly people suffer itching, dry skin, particularly during the winter months. Heating and lower humidity may lead to a condition often called "winter itch," which can be quite distressing. Dermatologists suggest that itch sufferers bathe without the use of soap, or use a cold-cream based soap. Water should be only tepid, not hot, and drying should be done in a patting rather than rubbing motion. (Medical Tribune 32(20)11, October 3, 1991) Copyright Phylis Austin

SLEEP PROBLEMS IN ELDERLY
Many elderly people complain of sleep difficulties. Researchers at Duke University Medical Center in Durham, North Carolina, studied 24 men over the age of 60. Half of the men in the study exercised regularly and were physically fit; the other half of men were healthy, but inactive.
Men who exercised fell asleep at night in half the time it took non-exercisers, woke up fewer times during the night, and had longer periods of refreshing, energy-restoring slow-wave sleep. (Medical Tribune 33(12) June 25, 1992) Copyright Phylis Austin

NATURE/ELDERLY APARTMENT DWELLERS
Elderly adults who had access to nature in their surroundings were significantly more satisfied with life than those who did not have this exposure. An apartment overlooking a park or wooded area may be very helpful to the elderly. (International Journal of Aging and Human Development 33(2)119-130, 1991) Copyright Phylis Austin

POOR APPETITE IN ELDERLY
Elderly people often complain that food does not taste good. In some cases this causes a reduction in the amount of food consumed, which may lead to malnutrition. Fergus Clydesdale, a University of Massachusetts food scientist reports that brightly colored foods may allow the sight to adjust for the lack of flavor, making food more appealing.

ELDERLY/WEIGHT TRAINING
Weight training decreases the risk of hip fractures in the elderly by improving muscle strength, and decreasing the risk of falls. It also provides cardiovascular benefits, and improves mental outlook. (Internal Medicine News and Cardiology News 27(19)1, 18, October 1, 1994) Copyright Phylis Austin

AIR POLLUTION/LONGEVITY
The air pollution which occurs in large cities may shorten lives. Heart disease, lung disease, and lung cancer were all highest in cities with the highest levels of air pollution. Tiny, invisible pollutants may be inhaled deeply into the lungs where they may cause disease.

EXERCISE FOR ELDERLY
High-intensity resistance exercise programs reduce physical frailty and counteract muscle weakness in elderly persons. (New England Journal of Medicine 330:1769-1775, June 23, 1994) It reduces the number of painful falls by increasing muscle control and dexterity. Therefore the person suffers fewer fractures.

WALKING/ELDERLY/HEART DISEASE
Walking more than four hours a week significantly reduces the risk of heart disease or death from heart disease in the elderly. (Journal of the American Geriatric Society 44: 113- 120, 1996) Copyright Phylis Austin

EXERCISE/DEPRESSION IN AGED
Inactive elderly persons are more likely to be depressed than are those who exercise regularly. Regular, intensive physical exercise was associated with better overall health and a meaningful life and satisfaction with life. Other studies have demonstrated improved cognitive function in exercising elderly. (Age and Aging 24:282-296, 1995) Copyright Phylis Austin

EXERCISE/AGING
Exercise is effective in slowing, or even preventing, many age- related declines in physical function. Muscle strength decreases 10 to 20 percent between the ages of 20 and 50, but decreases an additional 25 to 30 percent during the next 20 years. This decline can be slowed, or even prevented, by exercise. One study showed that 70-year-old men who actively participated in strength training from middle age were as strong as 28-year-olds who did not train. Strength training can double or triple the strength of 80- or 90- year-olds in just months.
Stretching is also important in maintaining good physical function into old age. It has been estimated that each decade of life brings a five percent reduction in flexibility. A regular stretching program may prevent this stiffness-related decline in function.
Inactive persons will benefit from exercise regardless of their age. Older individuals should warm up for five to ten minutes, and cool down slowly after the exercise period. A sudden cessation may produce dizziness, fainting, or other adverse effects.
Adequate fluid intake is important, the elderly are less likely to feel thirsty. Drinking 16 ounces of water about two hours before the exercise session and eight ounces every 20 minutes during the exercise session, and another cup about 30 minutes after exercise will prevent exercise-induced dehydration.

DIABETES/GLUCOSE INTOLERANCE/AGED
A study of over 7,000 men and women aged 55 or older revealed that undiagnosed diabetes mellitus and impaired glucose tolerance are common in the elderly. As the study group aged the incidence increased. Eleven percent of women under 60 years of age and 34.7 percent of women over 85 had abnormal glucose metabolism. Almost 9 percent of men less than 60 years of age and 24.3 percent of those 85 or older had abnormalities. Both diabetes and impaired glucose tolerance increase the risk of heart disease.

DIET/MENTAL ALERTNESS IN ELDERLY
A 15-year study from Loma Linda University revealed that elderly individuals with high caloric intake had lower cognitive function than did those who consumed a diet lower in calories.
Low educational attainment and the use of psychotropic drugs (drugs which affect mental function) were also associated with poorer mental function. (American Journal of Epidemiology 143(12)1181-1190, June 15, 1996) Copyright Phylis Austin

MODERATE EXERCISE/SLEEP IN ELDERLY
A study of elderly persons reporting sleep problems revealed that a moderate intensity exercise program (brisk walking for 30 to 40 minutes four days a week over a course of 16 weeks) improved sleep quality. Eight weeks into the study there was no marked difference between the exercising group and the non-exercisers, but by 16 weeks the benefits of exercise were evident.
Sleep problems are common in middle-aged and elderly persons, and this simple, drug-free treatment will not only improve sleep, but will improve over all health. (Journal of the American Medical Association 227(1)32-37, January 1, 1997) Copyright Phylis Austin

WALKING/MENTAL FUNCTION IN ELDERLY
Elderly cardiac patients with brain atrophy or dementia have improvement in their mental abilities, including memory, with a walking program. Those patients who walked the most had less brain atrophy than non-walkers. (Journal of Internal Medicine 238:423- 428, 1995) Copyright Phylis Austin

ANTIOXIDANTS/MEMORY IN AGED
People 65-years-of-age and older have better memories with higher levels of ascorbic acid and beta-carotene plasma levels. These antioxidants may slow the manifestations of brain aging. (Journal of the American Geriatric Society 45:718-724, 1997) Copyright Phylis Austin

HIGH BLOOD PRESSURE/BRAIN CHANGES IN ELDERLY
Structural changes occur in the human brain as we age. High blood pressure accelerates these changes, particularly shrinking the temporal and occipital regions. (Stroke 28:1410-1417, 1997) ED - Since most persons with high blood pressure who would participate in such a study are under the care of physicians who use drug medications to treat their hypertension we postulate that it is possible that the medications cause the shrinkage. We would like to see a comparison of patients treated with drugs and those treated with diet, weight loss, and herbal remedies. Copyright Phylis Austin
