Experimenteel: Low, then high added sugar diet
Participants will consume a low added sugar (5% total energy) diet for 7 consecutive days.
After a 4-week washout period, participants will then consume a high added sugar (25% total energy) diet for 7 consecutive days.

Controlled feeding study.
Participants will be provided with daily coolers containing foods with high (25%) added sugar to consume for 7 consecutive days.
Fasting fingerstick blood samples and weight checks will be performed each morning.

Validity, reliability, and sensitivity of the fingerstick blood d13C AS biomarker during cross-sectional data collection.
Participants will provide 4 separate self-reported, record-assisted 24-hr food intake recalls, and at two of the visits, a fingerstick blood sample will be collected to analyze delta13C biomarker levels.

Change in d13C: delta13C Added Sugar Biomarker
Tijdsspanne: Two 7-day feeding periods, randomized order, with a four-week washout between feeding periods. Outcome is a change in d13C from day 1 to 8, for each feeding period.

Validity, reliability and sensitivity of the fingerstick blood delta13C AS biomarker during feeding study.
Participants are provided 7 days of food with high or low added sugar diet.
Blood samples will be obtained each day via fingerstick to analyze delta13C biomarker levels.

Two 7-day feeding periods, randomized order, with a four-week washout between feeding periods. Outcome is a change in d13C from day 1 to 8, for each feeding period.

Diagnostic Value of d13C Biomarker
Tijdsspanne: 2-3 weeks
|
Determine diagnostic value of d13C biomarker using fingerstick blood.
The area under the ROC was used as a measure for the diagnostic accuracy of the d13C biomarker, with values closer to 1.0 indicating greater ability to distinguish between low and high added sugar and sugar sweetened beverage consumers.
