... Health status indicators, including life expectancy and heart disease death rates, have shown improvement, as have economic indicators. Among health risks and behavior indicators, Madans observed that diet quality is poor and the proportion of older Americans meeting recommended physical activity levels is quite low.
From page 2...
... In 2013, the average American life expectancy was 77 years, but average American "healthy life expectancy" was estimated at only 67 years. Whereas some may think of biomarkers as "things you can measure in your blood," Johnson presented that there is an extensive range of biomarkers for healthy aging, from markers of disease onset, progression, and severity to what Johnson described as "functional markers" of physical capability (e.g., strength, balance)

... She described recent trends in several risk factors for cardiovascular diseases, including the slow, steady increase in obesity among both adults and children; the decreasing but still high cholesterol levels, again, in both adults and children; and the increase in type 2 diabetes in children. She then went on to describe evidence from several studies showing how these and other cardiovascular risk factors in children relate to cardiovascular risk later in life.

... More specifically, they are related to skeletal muscle changes known as "sarcopenia," which Fielding described as age-associated loss in muscle mass and function. Age-associated difficulties in mobility, specifically a decreased ability to walk one-quarter mile, have been associated not only with increased functional decline, but also increased hospitalization rates and health care costs.

... . In addition to the effects of caloric restriction on longevity, de Cabo elaborated on the extensive mouse model work by Mark Mattson and colleagues showing a connection between energy restriction and the maintenance of optimal brain function and resistance to injury and disease.

... Based on this evidence that significant proportions of the population have inadequate nutrient intakes, combined with evidence that nutrient supplementation can improve nutrient intake, Mackay argued that the supplement industry's role in supporting healthy aging is to promote the responsible use of dietary supplements in combination with a healthy diet as a way to ensure nutrient adequacy. He listed the several ways they fill this role, such as investing in health care cost analyses of savings associated with achieving targeted nutrient intakes.

... However, she also stressed the need to come up with tangible markers of successful aging that span multiple domains and uses. In her opinion, health care providers need markers of aging that can be used to identify at-risk people and know when intervention is appropriate; governments need markers of nutritional intakes or other lifestyle changes that can be used specifically to guide the development of recommendations for older people; and the food industry needs markers of aging that can be used to validate the efficacy of products in specific target groups.

... The National Academies of Sciences, Engineering, and Medicine's planning committees are solely responsible for organizing the workshop, identifying topics, and choosing speakers. The responsibility for the published Proceedings of a Workshop -- in Brief rests with the institution.
