Abstract A prospective investigation of the impact ofingested liquids on 24-hr pH test scores was conducted.Eighty-two patients contributed 142 samples. The liquidsused were coffee/tea (N = 35), water (N = 32), fruit juice (N = 29), cola (N = 34), and beer (N =12). The pH of cola, juice, and beer are approximately3.0. The parameters studied included: total test time,total drink time, total minutes of pH 〈 4.0 during drink, minutes of pH 〈 4.0 10 min beforedrink, and minutes of pH 〈 4.0 10 min followingdrink. Analysis was performed using one-way ANOVA andrepeated measures. Age of patients, total test time, and total time pH 〈 4.0 were notsignificantly different (P 〉 0.05). The total time toconsume the drink was significantly greater (P 〈0.05) for beer than all other liquids. The total time(7.7 ± 6.0 min) pH 〈 4.0 for cola wassignificantly different (P 〈 0.023) than beer (3.3± 3.7 min), tea/coffee (1.4 ± 6.5 min),and water (1.1 ± 2.5 min). The percentage oftotal time pH 〈 4.0 was not significantly different (P 〉0.05) among any of the liquids. The percentage of timepH 〈 4.0 during the drink was the highest for cola(63 ± 47%) and juice (51 ± 57%); water,coffee/tea, and beer were not significantly different (P〉 0.05). Although the impact of cola and juice werethe greatest, none of these had an impact that exceeded0.5%. The lack of impact of beer appears to be due to the increased period of time it takes toconsume. We conclude that the impact of ingested fluidsis minimal and can probably be disregarded in mostpatient groups.
