Data are presented as mean±SD (Baseline), covariate-adjusted, mixed-model-based mean±SE (Intervention and Control) or covariate-adjusted, mixed-model-based mean (95% CI) (Difference). DASH: Dietary Approaches to Stop Hypertension (range 0–9 with higher scores indicating better DASH concordance); ACQ: Asthma Control Questionnaire (range 0–6 with higher scores indicating worse asthma control); MiniAQLQ: Mini Asthma Quality of Life Questionnaire; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity.
servings were calculated using the Nutrition Data System for Research per the 2000 Dietary Guidelines for Americans (fruit: one serving=1 medium apple, banana, orange or pear, 0.5 cups of chopped, cooked or canned fruit, 0.25 cups dried fruit or 4 fl. oz of fruit juice; vegetables: one serving=1 cup of raw leafy vegetables, 0.5 cups of other cooked or raw vegetables or 4 fl. oz of vegetable juice; dairy: one serving=1 cup of milk or yogurt, 1.5 oz of natural cheese or 2 oz of processed cheese).
