On the basis of 2000 kcal/d. Average across a 7-d menu cycle. Values were determined by chemical analysis (Covance Laboratories, Inc.). AAD, average American diet; ALA, α-linolenic acid; MED, Mediterranean-style eating pattern used in the study; MED0.5, MED diet with 14 g (0.5 oz) per day of lean beef; MED2.5, MED diet with 71 g (2.5 oz) per day of lean beef; MED5.5, MED diet with 156 g (5.5 oz) per day of lean beef based on a 2000-kcal diet. % E, percentage of total energy.
2Values were determined using FOOD PROCESSOR (ESHA Research).
