The glycemic index (GI) measures how a carbohydrate-containing food raises blood glucose. Fat and fiber content tend to lower the glycemic index (GI) of a food. As a general rule, the more cooked or processed a food, the higher the GI. When starches are cooked in boiling water (as with home-cooked rice or boiled potatoes), their GI is fairly low, around 50-60: but when they are roasted at high temperatures, their GI often approaches 100. Avoid industrially prepared foods.
Does heat 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.
How can I lower my glycemic index quickly?

Does cooking potatoes lower the glycemic index?
The GI is a measure of the blood glucose raising potential of carbohydrate containing foods. We previously found that eating cooled or reheated potatoes reduces their GI by 30–40%.
Does cooking fruit lower glycemic index?
Ripeness: The sugar in fruit breaks down as the fruit ripens, increasing the GI score. Preparation: The cooking process can break down carbohydrates, increasing the meal's GI score.
Does cooking alter the glycemic index of rice?
The results showed that cooking slightly altered the GI of two rice varieties used in this study: raw [foreign rice (48.4%) and ofada rice (49.2%)] and cooked [foreign rice (49.0%) and ofada rice (51.8%)]. The effect of cooking on the amylose and amylopectin contents is presented in Table 2.
Do low glycemic index foods improve glycemic control?
Howlett and Ashwell (2008) reported that low GI foods improve glycemic control by lowering glycated end‐products and improving insulin sensitivity. However, GI does not measure the quantity of carbohydrate, but its quality (Foster‐Powell, Holt, & Brand‐Miller, 2002).
What is the concept of glycemic index (GI) of food?
The concept of GI was proposed with the aim of assisting diabetic subjects in selecting their foods, with recommendation that foods with low GI are good for diabetic patients (Thorne, Thompson, & Jenkins, 1983). Using glucose as standard, foods can be classified into low (≤55), medium (55–69), and high (≥70) GI (Jenkins et al., 1981).
How does starch affect the glycemic index?
The slower a starch is digested (broken down and converted into simple sugars), the lower its glycemic index, which is a measure of how much glucose, the main sugar your body uses (also known as dextrose), is present in a typical person’s blood a set time after a particular food is consumed.
