Does cooking increase glycemic index?

The results of this study showed that cooking increased the antioxidant activities, glycemic indices, and enzyme inhibitory properties of two rice varieties (ofada and foreign), but has no effect on their phenolic contents. However, the rice varieties used in this study could be categorized as low GI food.

Does cooking time affect glycemic index?

As a general rule, the more cooked or processed a food, the higher the GI. There are several factors that can affect the glycemic index (GI) of a food. These factors include: Ripeness and storage time: The more ripe a fruit or vegetable is, the higher the GI.

What factors affect glycemic load?

Factors affecting the glycaemic load

These include: the types of sugar and starches in the food, the way it is prepared, its fat, fibre and carbohydrate content, and the serving size. The rate of absorption and digestion of food products also influences the GI and GL.
