Improved nutritional status is an important component of efforts to improve the health of older adults, whose ability to consume a healthy diet is affected by comorbidities and behavioral, cognitive, and psychological factors. In addition to genetics and nutrition intake, nutritional status of the elderly could be affected by socioeconomic factors, such as education and income levels, and environmental factors, such as proximity to stores and transportation, that can affect food variety and availability. Nutrition and aging are connected inseparably because eating patterns affect progress of many chronic and degenerative diseases associated with aging. Anthropometric measurements are often used for nutritional assessment of older adults and are reliable across ethnicities. The Mini-Nutritional Assessment (MNA) tool was developed to evaluate the risk of malnutrition among frail older adults. Dietary patterns may better capture the multifaceted effects of diet on body composition than individual nutrients or foods.
