¹ Models adjusted for carbohydrate intake at breakfast, lunch, or dinner, as appropriate. Data used in the analyses were from 57 breakfast meals among 37 women, 50 lunch meals among 34 women, and 50 dinner meals among 35 women. DI, disposition index; GLUC_2hPP, 2-h postprandial glucose area under the curve.
