Many people eat rice every day. It is tasty, filling, and easy to cook. But if you are someone who is trying to manage blood sugar levels or lose weight, you might wonder, “Which rice has the lowest glycemic index?” This is an important question, especially for people with diabetes or those following a healthy diet plan. The glycemic index (GI) measures how quickly food raises your blood sugar levels. Some types of rice have a high GI, while others have a lower GI and are better for your health.
In this blog, we will explain everything in simple language and help you choose the best rice for your health needs.
What is Glycemic Index?
The glycemic index is a number between 0 and 100. It tells you how fast a food with carbohydrates increases your blood sugar after eating it. Foods with a high GI (above 70) raise your blood sugar quickly. Medium GI foods (56–69) raise it more slowly. Low GI foods (55 or below) raise blood sugar slowly and are better for long-term health.
When you eat low GI foods, your body gets energy slowly. This means you feel full longer and don’t get hungry quickly. This helps with weight control and managing diabetes.

Why is the Glycemic Index of Rice Important?
Rice is eaten all over the world, but not all rice is the same. Some types of rice have a higher GI, meaning they increase blood sugar fast. This can be a problem for people with diabetes or those trying to stay healthy.
If you eat rice that has a low glycemic index, it won’t cause sudden spikes in your blood sugar. This helps your body manage insulin better and reduces the risk of type 2 diabetes. It also helps you feel full for longer, so you don’t overeat.
Types of Rice and Their Glycemic Index
Let’s look at some common types of rice and how they compare based on their glycemic index.
1. White Rice
White rice is the most common type of rice. It is soft and cooks quickly. But it has a high glycemic index—usually between 70 and 89, depending on the variety and how it’s cooked. This means it increases your blood sugar quickly. It is not the best choice if you are watching your blood sugar.
2. Brown Rice
Brown rice is a whole grain. It still has the bran and germ, which gives it more fiber and nutrients. Brown rice has a medium GI, usually around 50 to 66. It is a better option than white rice because it raises blood sugar more slowly and keeps you full longer.
3. Basmati Rice
Basmati rice, especially brown basmati rice, has a low to medium GI—around 50 to 58. Even white basmati rice has a lower GI than regular white rice. Basmati is long-grain rice and has a nice aroma and taste. It is a good choice if you want to eat rice but also want to keep your blood sugar stable.
4. Parboiled Rice (Also Called Converted Rice)
Parboiled rice is partially boiled in the husk before being processed. This process helps the nutrients move into the grain. Parboiled rice has a GI between 38 and 60, which is lower than regular white rice. It is a smart choice if you want to eat low GI rice.
5. Black Rice
Black rice is also known as forbidden rice. It is rich in fiber, antioxidants, and nutrients. The glycemic index of black rice is low to medium—usually around 42 to 45. It has a nutty flavor and chewy texture. It is one of the healthiest types of rice.
6. Red Rice
Red rice is another whole grain rice that contains a high level of nutrients. It has a GI of around 55, making it a low GI food. It is rich in fiber and helps control blood sugar and cholesterol.
So, Which Rice Has the Lowest Glycemic Index?
Among all the types of rice mentioned above, the lowest glycemic index is found in parboiled rice, black rice, and brown basmati rice. These types digest slowly, do not spike blood sugar quickly, and help in weight management. If your main goal is to control your blood sugar, these should be your top choices.
Tips to Lower the GI of Rice When Cooking
Even the way you cook rice can affect its glycemic index. Here are some simple tips to lower the GI of rice:
- Use less water while cooking to avoid making it too soft.
- Let the rice cool after cooking. Cooled rice forms something called “resistant starch,” which lowers the GI.
- Reheat the cooled rice before eating. It still has a lower GI even after reheating.
- Add vegetables or protein like lentils, chicken, or beans. These slow down digestion and help lower the overall GI of your meal.
- Avoid frying rice in oil or butter, as it adds extra calories.
Rice and Diabetes: What You Should Know
If you have diabetes, choosing the right kind of rice is very important. Low GI rice like brown rice, parboiled rice, or black rice can help manage blood sugar better. It’s also good to control portion size. Instead of eating a full plate of rice, eat a small portion with lots of vegetables or salad. This balance helps slow sugar absorption.
Rice Portion Control Tips
Even low GI rice can raise blood sugar if you eat too much of it. Here are some tips for portion control:
- Use a measuring cup to serve rice. A ½ cup of cooked rice is a good portion.
- Fill half of your plate with vegetables, one-quarter with rice, and one-quarter with protein like beans or meat.
- Eat slowly and stop when you feel full.
Conclusion
Rice is a major part of many people’s diets, but it’s important to choose the right kind of rice for better health. If you have been wondering, “which rice has the lowest glycemic index,” the answer is simple: go for parboiled rice, black rice, or brown basmati rice. These types of rice help control blood sugar, keep you full longer, and are packed with nutrients. You don’t have to give up rice completely to stay healthy—just choose smarter options and eat them in the right portions. With the right knowledge and habits, you can enjoy rice as part of a healthy and balanced diet.
