Health Benefits

Compared to brown rice or other whole grain varieties, white rice has a lower nutritional value due to the removal of the bran and germ components of the grain during processing.

However, white rice can still provide health benefits to those who consume this delicious grain, especially if the rice is prepared in a certain way. Research has shown that eating rice after it has cooled increases the amount of resistance starch present.⁶ Health benefits from resistant starch include improved insulin sensitivity, lower blood sugar levels, reduced appetite, and improved digestion.

Quick Energy Source

White rice is packed with carbohydrates, which allows it to provide energy to the human body very quickly. This is the main reason why athletes choose white rice over other varieties when they need an energy boost.

Gut Healthy

If you ever experienced diarrhea, your healthcare professional may have recommended eating boiled white rice. This advice is based on the fact that white rice contains butyrate, a short-chain fatty acid that reduces inflammation in the gut.⁷

Gluten-Free

White rice is naturally gluten-free, making it the perfect option for individuals with gluten intolerance or celiac disease. It can be used as a replacement for wheat, barley, or rye in many recipes, allowing those with dietary restrictions to enjoy a larger variety of foods. Rice can also be turned into flour, noodles, and bread for people who opt for gluten-free varieties.

Easily Digestible

The outer husk, bran, and germ are removed from white rice during processing. Phytic acid, often causing digestive issues in humans, is also removed, which makes white rice one of the easiest digestible varieties of rice. White rice is also bland and low in fiber, which makes it an optimal choice for individuals with digestive problems, nausea, or heartburn.

Another strategy to reduce blood sugar spikes when eating white rice is to pair this food with a lean protein and healthy fat source. This will slow down the absorption of the white rice, leading to less of a spike in your glucose levels.
