  • Studies have been done in animals, such as monkeys, mice, chimpanzees, & fruit flies, that show there is a possibility for people to live longer.
  • These studies were done by reducing the animal species diet.
  • Most scientists believe that aging is associated with cellular level; however, not all scientists think that aging involves one gene. Many believe that aging is the result of “multiple cellular pathways” where there is no one factor acting out.
  • Most research that is done is not based on how to prevent aging; however, it is done on how to prevent disease, increase health, etc.
  • Getting enough nutrients is more problematic for the aged than for younger adults primarily because the senses of taste and smell diminish with age.
  • Poverty, living alone, and dental problems are external factors that make getting enough nutrients more difficult for some older adults.
  • Life expectancy in Sweden is high; where as life expectancy in Russia and Africa are low.
  • A centenarian is someone still alive after his or her 100th birthday.
  • Four characteristics of long-lived people follow:

         •  Diet is moderate.
         •  Work continues throughout life.
         •  Family & community are important.
         •  Exercise & relaxation are part of the daily routine.

  • Calorie requirements decrease with age, where as vitamin and mineral intake increase with age.
  • Drugs, alcohol, and dehydration also play an important role in nutrition for the elderly.
  • The general public says they want to live longer; however, nobody wants to sacrifice anything to be able to do so.
  • Exercise is needed more among the elderly but they do it less. Continuous rhythmic movements should be done for exercise not sudden, strenuous effort exercises.
  • Fewer than 1 percent of people over the age 50 currently are on a diet or exercise.
