1Nutrient intakes from MLPF were based on 3-day food records (n = 13; classical PKU, n = 10; variant PKU, n = 3). Participants that did not consume MLPF at the end of both treatments were removed from the analysis. MLPF were defined as foods modified to be low in protein and specifically made for individuals with disorders that have dietary protein restrictions. Statistical analysis included ANOVA with effects for treatment, genotype, and treatment-genotype interaction. The values in this table represent the treatment comparison. There were no significant differences due to genotype or the treatment-genotype interaction (data not shown); Kruskal–Wallis test was used when data were skewed; MLPF, modified low-protein foods.
