Does Boiling Rice Affect its Nutrition Facts? Unveiling the Truth Behind Cooked White Rice

When it comes to cooking, one of the most common questions that arise is about the nutritional value of the food we prepare. Rice, a staple food for more than half of the world’s population, is no exception. The question of whether boiling rice affects its nutritional facts is a valid one, considering the significant role rice plays in our diets. This article aims to unveil the truth behind the nutritional facts of cooked white rice, and whether these facts change after boiling.

Understanding the Nutritional Facts of Raw White Rice

Before we delve into the effects of boiling on rice, it’s important to understand the nutritional facts of raw white rice. A 100-gram serving of raw white rice contains approximately 70 grams of carbohydrates, 7 grams of protein, 0.6 grams of fat, and 1.3 grams of fiber. It also contains essential minerals like iron and magnesium.

Does Boiling Affect the Nutritional Facts of Rice?

When you boil rice, its weight increases due to the absorption of water. However, the nutritional content per 100 grams of raw rice does not change significantly. The increase in weight is due to water, which does not contribute any calories, carbohydrates, proteins, or fats. Therefore, if you measure your rice after cooking, it will contain fewer nutrients per 100 grams simply because each gram of cooked rice contains more water and less rice.

What Happens to the Nutrients During Cooking?

While the basic macronutrients (carbohydrates, proteins, and fats) remain relatively stable during cooking, some loss of vitamins and minerals can occur. This is because these nutrients are water-soluble and can leach out into the cooking water. However, the extent of this loss is generally minimal and can be reduced by using less water or by consuming the cooking water, as in the case of a rice soup or stew.

Does the Cooking Method Matter?

Yes, the cooking method can affect the nutritional value of rice. For instance, steaming rice retains more nutrients compared to boiling. This is because steaming uses less water, reducing the amount of nutrients that can leach out. Additionally, rinsing rice before cooking can remove some of the surface starch, which can slightly lower the carbohydrate content.


In conclusion, while boiling does cause some minor loss of nutrients in rice, the overall nutritional profile remains largely the same. The increase in weight of the rice after cooking is due to water absorption and does not significantly affect the nutritional content per 100 grams of raw rice. Therefore, you can continue to enjoy your boiled rice without worrying about significant nutrient loss.
