When it comes to its dietary properties, rice is notoriously blubbery for the human body. Just one cup of cooked white rice contains around 205 calories- not too good for the waistline. Hence, over the years, experts have been attempting to figure out ways to reduce calorie content in cooked rice, and it seems, they’ve found one. In a 2015 study, researchers from Sri Lanka discovered a way to cook rice that promises to reduce as much as half of its calorific content, reported Science Alert. The key to this method lies in a magical ingredient that rice contains: resistant starch.

Unlike digestible starch, “resistant starch” is a special type of carbohydrate that has the property that it resists digestion. Instead of getting converted into glucose molecules in the small intestine, it is simply metabolized in the colon and fermented into short-chain fatty acids that lubricate the colonies of healthy gut bacteria. The more resistant starch a food has, the lesser its ability to trigger a huge blood sugar spike in the body. By simulating the human digestive system in test tubes, the researchers devised a remarkable recipe that can slash nearly 60% of calories from the rice by increasing its resistant starch.

The method is simple. It just involves adding a spoonful of coconut oil to the boiling water, adding white rice, and then cooling the cooked rice in the refrigerator for about 12 hours. This cooling process increases the resistant starch, which decreases the amount of sugar the body will absorb when this rice is consumed. “Resistant starch acts like a dietary fiber,” Darrell Cockburn, associate professor of food science at Penn State University, told TODAY. “In addition to feeding the microbes in the gut, resistant starches slow down sugar production and absorption, which means they do not spike blood glucose as much as other starches.”

Grace Derocha, registered dietitian and spokesperson for the Academy of Nutrition & Dietetics, further explained how the cooling process cuts down the calorific value of cooked white rice. Cooking, she said, typically destroys all the resistant starches in the foods. When served hot, rice carries a loose structure of glucose molecules that are easily digestible and can, therefore, increase blood sugar. The enzymes in the stomach can easily break down these loosely held glucose chains and instantly convert them into body fat.

The process of cooling ensures that these loose-bound structures are tightened and resist digestion. “When you cook the rice and cool it in the refrigerator, what you’re doing is tightening those molecular bonds (so) they’re more resistant to digestion... which builds up the resistant starch,” Derocha told the media channel. She further added that consuming cooked rice after cooling it down results in a double benefit, “Not only are you cutting out some of the carbs so your blood sugar doesn’t rise as fast, (but) you now have this resistant starch that works like fiber to feed good bacteria in the gut.”

Pushaparaja Thavarajah, lead co-author of the 2015 study, affirmed the same point in an interview with TIME, saying, “The resistant starch is a very good substrate, or energy source, for the bacteria inside the human gut.” Researchers are now wondering if they can apply similar hacks to cut calories from foods like potatoes and bread. If an individual could eat a potato sandwich or a bag of potato chips at half the calories, it could turn out to be revolutionary for the generation that is still grappling with the temptations of taste.
