1

Values are means ± SDs unless otherwise indicated. *Significant at α = 0.05. AS, added sugars; TS, total sugars.

2

Sample was restricted to participants with 2 complete 24-h urine collections.

3

For 5% AS, one outlier was excluded as a result of SPSS identification as an extreme value for sucrose excretion. The second outlier identified was already excluded via incomplete sample. For 25% AS, 2 outliers were excluded as a result of SPSS identification as extreme values for sucrose excretion; a third outlier identified was already excluded via incomplete sample.

4

Correlations between AS intake and sucrose excretion.

5

Correlations between AS intake and fructose excretion.

6

Correlations between AS intake and TS excretion.
