⏱ Blood Sugar Timeline
- 0–15 min: Minimal impact as cornstarch is not consumed alone and its effect depends on how it's used in cooking.
- 30–60 min: Blood sugar levels may begin to rise depending on the amount of cornstarch used and its combination with other foods.
- 2–3 hr: Blood sugar levels may peak if cornstarch is consumed in significant amounts, especially in processed or thickened dishes.
