Concurrent Beet Juice and Carbohydrate Ingestion: Influence on Glucose Tolerance in Obese and Nonobese Adults

Figure 1

Schematic of experimental visits. Two modified oral glucose tolerance tests were administered, on two separate occasions, in a random order. At the start of one visit, participants completed 3 × 1 min mouthwash regimen. Without delay, they then ingested beet juice supplemented with glucose within 5 minutes. Venous blood (~3–10 mL) was sampled repeatedly over 120 minutes and analyzed for concentrations of glucose and insulin. See text for more details.
