JAKARTA - Croissant is a part of pastry that is popular and liked by many people. However, as part of a pastry that is rich in fat, the consumption of croissants certainly has an influence on blood sugar in the body.
Quoted from Verywell Health, on Monday, December 15, 2025, croissants are made from a mixture of flour, butter, milk, sugar, water and salt. The combination of these ingredients makes croissants high in carbohydrates and fat, but relatively low in fiber and protein.
When eating croissants, the digestive system will break down carbohydrates into glucose which then enters the bloodstream. The food has a high glycemic index, so the process occurs quickly, and blood sugar can rise in a short time.
The spike usually gives a quick sense of energy. However, it can then cause a decrease in energy that feels like being tired or sleepy after some time.
However, on the other hand, there is an assumption that croissants that are already cold can reduce blood sugar spikes. This is because there is a change in starch structure, where some of the starch can turn into a resistant that is more difficult for the body to digest.

This type of starch does not immediately increase blood sugar and can actually be beneficial for intestinal health. However, in croissants, this effect is very small because the amount of starch that can turn into resistant starch is very limited, so cooling the croissant does not make a significant difference to the blood sugar response.
"When a baked bread like a croissant cools, the gelatinous starch, especially amylose, begins to reassociate and recrystallize into a more ordered structure," said associate professor at the University of South Florida, Heewon Gray, PhD, RD.
Therefore, there are several ways that can be done for croissant consumption to be healthier. The key lies in portion and food combinations.
Like eating croissants in smaller amounts and combining them with foods rich in protein and fiber. This way can help reduce blood sugar spikes.
"If you eat a croissant with a little protein, think cheese or eggs, it will have a better effect on your blood sugar. If you pay attention to your blood sugar, what it does is reduce the portion of the croissant," said nutrition lecturer, Amanda Sauceda, MS, RD.
