¹ORs >1 denote greater odds of healthy aging. These analyses included 1517 healthy agers versus 12,301 usual agers for all foods except onions, for which analyses included 1401 healthy agers and 11,036 usual agers (e.g., women with onion intake assessed in 1990). Logistic regression models were adjusted for age (y); education (associate's degree, bachelor's degree, graduate degree); marriage status (married, widowed, or separated/divorced); median income (quintiles), median house value (quintiles); family histories of diabetes, cancer, and myocardial infarction (yes or no); physical activity (quintiles of metabolic equivalent task-hours); energy intake (quintiles of kcal); smoking (never smoker, past smoker of 1–14, 15–24, or ≥25 cigarettes/d, or current smoker of 1–14, 15–24, or ≥25 cigarettes/d); multivitamin use (yes or no); aspirin use (<1, 1–2, or >2 tablets/wk); BMI (in kg/m²; <22, 23–24, 25–29, or ≥30); history of high blood pressure (yes or no); history of hypercholesterolemia (yes or no); and Alternative Healthy Eating Index-2010 score (quintiles). Foods were introduced in separate models.

²Included intakes of fresh fruit and juices.
