Insulin response difference

This graph illustrates how blood insulin levels (measured in uU/ml) change over time (in minutes) after the consumption of three different macronutrients: carbohydrates (red), proteins (blue), and fats (green).

Carbohydrates (Red line)

This macronutrient triggers the most intense and rapid insulin response.

Peak: It reaches its maximum around the 40-minute mark, well above 100 uU/ml.

Course: After the initial surge, it begins to decrease relatively quickly and by 180 minutes, it approaches the protein level.

Proteins (Blue dashed line)

Proteins elicit a moderate insulin response.

Peak: It also peaks around the 40-minute mark, but at a much lower level (approx. 70 uU/ml) than carbohydrates.

Characteristic: Interestingly, at the end of the graph (after 200 minutes), protein maintains the highest insulin level among the three macronutrients.

Lipids / Fats (Green line)

The consumption of fats results in the smallest increase in insulin.

Effect: Insulin levels rise only slightly (to a maximum of approx. 45 uU/ml) and quickly return close to the baseline.

Summary

The graph clearly demonstrates that insulin secretion is primarily stimulated by carbohydrates, while fats have the least effect on this function of the pancreas.
