Document Summary
Chapter 12- nutrition through the life span: later adulthood. Life expectancy in the united states increased dramatically in the 20th century. Factors that enhance longevity include limited or no alcohol use, a plant-based eating pattern, weight control, adequate sleep, abstinence from smoking, and regular physical activity. Nutrition alone, even if ideal, cannot guarantee a long and robust life. At the very least, however, nutrition--- especially when combined with regular physical activity--- can influence aging and longevity in human beings by supporting good health and preventing disease. Cataracts, age-related macular degeneration, and arthritis afflict millions of older adults, while others face senile dementia and other losses of brain function. Oxidative stress plays a significant role in the development of cataracts, and the antioxidant nutrients and phytochemicals in fruits and vegetables may help minimize the damage. Weight loss can help overweight people with osteoarthritis.
