How does nutrition influence longevity of older adults in United States today?

Inquiry question

How does nutrition influence longevity and healthy aging among older adults in the United States today?

Working thesis

Proper nutrition is crucial for increasing the lifespan of older adults in the USA, as it helps reduce the risk of chronic illness, supports overall physical and mental health, and encourages healthy aging. However, challenges such as unequal access to quality diets and limited scientific data prevent fair application of nutritional science to improve longevity.

Synthesis paragraph

Nutrition is increasingly recognized as essential for healthy aging and longevity in seniors. Leitão et al. (2022) conducted a systematic review showing that diet impacts aging at a biological level, with “nutritional patterns influence inflammation, oxidative stress, and metabolic pathways that are strongly associated with aging-related biomarkers” (p. 554). This biological evidence aligns with population data. Molani-Gol et al. (2025) found that older adults who eat a varied diet, including different food groups and nutrients, generally have better functional health, less frailty, and more positive aging markers. While Leitão et al. (2022) focus on cellular mechanisms of nutrition’s effect on aging, Molani-Gol et al. (2025) show how these processes lead to tangible health benefits. Overall, these studies highlight that diet quality and diversity are crucial for biological aging at the molecular level, supporting longer life and better well-being in later years Exploratory analysis essay example.
