a
Data are expressed as mean (SE) unless otherwise indicated.
b
Adherence score was calculated as 30 points for each vegetable or fruit serving (excluding white potatoes, juice, and iceberg lettuce); 10 points for each ounce of vegetable juice; 5 points for each percentage point of energy from fat below 40% to a maximum of 100 points for 20% energy from fat; and 7.7 points for each gram of fiber per 1000 kcal above 5 g/1000 kcal. Perfect adherence was 600 points.
