Scientists developed simple way to cook rice that cut calories absorbed by half
- vaidhy 4y agoCan we add 2015 to the title? It was presented then.
- dilippkumar 4y ago>…they added a teaspoon of coconut oil to boiling water. Then, they added a half a cup of rice. They simmered this for 40 minutes, but one could boil it for 20-25 minutes instead, the researchers note. Then, they refrigerated it for 12 hours. This procedure increased the RS by 10 times for traditional, non-fortified rice. From deep inside the article.
- cwillu 4y agoThe team experimented with 38 kinds of rice from Sri Lanka, developing a new way of cooking rice that increased the RS content. In this method, they added a teaspoon of coconut oil to boiling water. Then, they added a half a cup of rice. They simmered this for 40 minutes, but one could boil it for 20-25 minutes instead, the researchers note. Then, they refrigerated it for 12 hours. This procedure increased the RS by 10 times for traditional, non-fortified rice. How can such a simple change in cooking result in a lower- calorie food? James explains that the oil enters the starch granules during cooking, changing its architecture so that it becomes resistant to the action of digestive enzymes. This means that fewer calories ultimately get absorbed into the body. “The cooling is essential because amylose, the soluble part of the starch, leaves the granules during gelatinization,” explains James. “Cooling for 12 hours will lead to formation of hydrogen bonds between the amylose molecules outside the rice grains which also turns it into a resistant starch.” Reheating the rice for consumption, he notes, does not affect the RS levels. So the key ingredient is cooling for 12 hours. Simple, but not exactly in the sense a casual reader might infer from the title.
- danso 4y agoHow essential is the teaspoon of coconut oil?
- gumby 4y agoThe article says they don’t know yet, but want to find out.

- newsclues 4y agohttps://pubmed.ncbi.nlm.nih.gov/26693746/ https://pubmed.ncbi.nlm.nih.gov/26693746/ "In conclusion, cooling of cooked white rice increased resistant starch content. Cooked white rice cooled for 24 hours at 4°C then reheated lowered glycemic response compared with freshly cooked white rice." it's the cooling, I don't understand why this isn't explained.

- jimbob45 4y agoDoes heating it back up change things? Cold rice seems unenjoyable.
- realitysballs 4y agoThe said reheating is fine and does not break the RS bonds down
- thriftwy 4y agoYour body has certain nutritional expectations from eating food, and if you mess with it, your hunger will just go up. That's also why sugarless drinks don't help you - they only confuse your body even more and trick it into eating more. The trick of not being obese is eating less. One of options here is eating fewer times a day, but there's more than one option. Once you adjust you will have no problem eating less.
- tlholaday 4y agoAnd the trick to eating less is to reduce appetite, and the trick to reducing appetite is to chew and swallow plenty of resistant starch (which you can’t eat but which your one-hundred-trillion-cell gut bacteria eat with bliss) so that your gut bacteria stop demanding “feed us” through your vagus nerve.
- p1necone 4y ago> sugarless drinks don't help you Citation needed...
- sammalloy 4y agoHeh, I figured this out quite by accident several years ago. I noticed that I tended to gain less weight when I cooled the rice in the fridge just after cooking it, instead of eating it straight from the pot. I couldn’t explain it.
- ackbar03 4y agoIt's kind of wierd that obesity is such a problem now in developing countries that something like this is a worthy research output. Some of my ancestors had to eat tree bark to avoid starvation. They'd be so confused by this
- mertd 4y agoIn the 90s the predominant fear of overpopulation used to be that we would run out of food. Now we know not that making food is easy, but we wreck the environment along the way.
- justinator 4y agoMaking specific monocrops with petroleum-based fertilizers is easy, but monocrops with petroleum-based fertilizers is not a sustainable practice if we would like to continue to live on Earth.
- deschutes 4y agoIt's a common thought but from what I can tell it's probably not true. Natural gas is simply the cheapest and most scaled way of producing ammonia (which is the critical ingredient in fertilizer production). Apparently electrolysis could come within a factor of 2 in terms of price. Also worth considering that passenger aviation is on the same order of magnitude in terms of CO2 emissions. Remarkable given everyone has to eat. https://ourworldindata.org/emissions-by-sector https://ourworldindata.org/emissions-by-sector
- justinator 4y agoI was thinking of terms of how monocrops work: we kill everything that's living (that's more complicated than a single cell organism let's say) to plant one species, then use fertilizers to help it grow from soil that's being depleted of it's own nutrients, while also spraying it with pesticides to make sure nothing else eats it. Seems that's not a great play, long-term. >Also worth considering that passenger aviation is on the same order of magnitude in terms of CO2 emissions. Remarkable given everyone has to eat. Interesting. Since I don't have to fly, I don't. (I don't drive, either).
- dbsmith83 4y agoImportant to note, the presentation showed a reduction of 10-12%, not half. The half is just a prediction if a more ideal rice candidate were found. https://health.usnews.com/health-news/blogs/eat-run/2015/04/21/does-the-calorie-slashing-method-for-cooking-rice-really-work https://health.usnews.com/health-news/blogs/eat-run/2015/04/...

- pengaru 4y agoThat's pretty neat. The Resistant Starch 2 (RS2) in green bananas has served as my bowel-regulating medicine for decades now. TFA makes me wonder if rice prepared this way could have a similar effect. It's a nuisance to keep green bananas onhand for breakfast daily, and once they turn yellow the RS2 has become sugar and the medicinal value is gone. Rice however...
- justinator 4y agoHa, interesting: green bananas, the first prebiotic.
- antonvs 4y agoPlus rice pudding can make a great breakfast.
- ianai 4y agoHow do you make that work? Practically.
- pengaru 4y agoFortunately it's not unusual for the grocery stores around me (CA) to put out bananas so green it requires a knife to peel them. Those last about a week before turning too yellow just hanging from a hook in the kitchen. When I visited family in IL last summer it proved quite difficult and I was often visiting multiple stores on shopping trips just to find bananas remotely green. My quality of life jumps off a cliff every time I visit, this is part of why. The produce availability sucks there in general compared to CA.
- squarefoot 4y agoI wonder if the same technique could also be effective with pasta, cereals, etc.
- fanf2 4y agoCooling and reheating pasta also converts it to resistant starch. https://www.sciencealert.com/heating-your-pasta-makes-it-significantly-better-for-you https://www.sciencealert.com/heating-your-pasta-makes-it-sig...
- xwdv 4y agoInstead of reducing calories by half why not just eat half?
- Dylan16807 4y agoSo there's this thing called "hunger"
- xwdv 4y agoDon’t you need the calories if you’re hungry???
- Dylan16807 4y agoOnly some of the time.
- amanaplanacanal 4y agoIt appears that if you eat too much sugar over time it fucks your hunger signaling system so that you feel hungry even when you don’t need more calories. Or something like that.
- DontchaKnowit 4y agoWhy? Rice is sustenance food, aint nobody blowing their calorie likits on rice everyday...
- coldtea 4y agoBoiled, fried, in sweets, etc, rice is like 1/4th of what billions eat every day the way westerners eat bread or potatoes... You know, in Asia and everything...
- DontchaKnowit 4y agoRight, I'm just saying like, no one is having issues with too much calorie consumption cause they couldn't stop eating... rice. It would be just as weird as trying to take the calories out of lentils or beans. It's not a particularly calorie dense or indulgent food. Wtf is the point of eating it if you strip the calories out of it? that's what its for, its food. Now something like butter or sugar, sure that makes sense. Calorie dense, and there are a lot of super tasty and addictive foods, that no one is eating as a meal, or to get full, that use a ton of of both of those ingredients.
- andsoitis 4y agoso you could feed two people if the first person just ate less, instead of this cooking hack?
- robbywashere_ 4y agoWho is getting obese eating rice?
- justinator 4y agoThis is actually a fantastic question. My guess is that hardly anyone is.
- sandworm101 4y agoChina is facing a burgeoning obesity crisis. One might hope also that this research could be applied to corn, corn being probably half of the extra sugars in the US diet.
- andsoitis 4y ago> China is facing a burgeoning obesity crisis. surely not due to rice consumption, though?
- paulpauper 4y agoit is basic CICO. does not matter what it is rice can be pretty caloric dense
- wenc 4y agoI can't speak for everyone but I did get obese eating rice. I ate a lot of it. In Asian diets, the one thing people often overindulge in is rice -- not everyone of course, but for those who do overindulge, their preferred carb is rice. (it's the same as eating too much bread and pasta in western diets, which is all too common among my friends) When I cut back on my rice portions (1/4 cup uncooked vs 1 full cup), I went from 160 lbs to 150lbs. At 160 lbs I had obstructive sleep apnea and felt really unhealthy overall. At 150 lbs now I feel so much better.
- sandworm101 4y agoIm not sure that inventing ways to make rice less nutritious, in order to allow us to safely eat more, is going to help the various co2/water/food insecurity battles we now face. We need ways to feed more people with less food/energy, not new ways to shovel more food into fewer people.
- true_religion 4y agoIt's not to help people eat more rice. It's do help people lose weight while eating the same amount when they are unable to change their diet dramatically. In the end, they will eat even less because they lost weight.
- quickthrower2 4y agoSkeptical. If you have the will power or habit changing power to make rice such a staple of your diet that this makes a difference, then you also have the ability to just eat less food. Same thing. Shit diet (cakes, bacon, fries etc.) -> heavy low carb rice diet Shit diet -> Good diet (balanced, carbs, protein, fat, veggies) I would say the second transition is easier. Perhaps more expensive though.
- bagavi 4y agoWhy not both? I want to be able to eat rice without feeling bad about the calorie intake
- sacnoradhq 4y agoRice cakes are this already. They're pressed puffed rice, usually without sugar added. A different kind of puffed rice with sugar added is known as the breakfast cereal Rice Krispies.
- drivingmenuts 4y agoEat less rice, maybe? A lot of our problems with food begin and end with the idea that we need to eat ginormous quantities of it, when moderation would fuel us just as well.
- starfleet_bop 4y agoIn other news, eating half the amount of rice results in half the amount of calories absorbed.
- darth_avocado 4y agoUncle Roger will be very happy with this discovery.
- kleiba 4y agoI bet that most obese people did not become obese from consuming too much rice.
- kleiba 4y agoInteresting observation: the countries in which traditionally the most amount of rice is consumed are not the ones facing the biggest problems with obesity.
- paulpauper 4y agoRemarkable that people are so overfed we have to invent ways to make food less nutritious. This is the first time in all of the existence of humanity that this is a problem. crazy
- siliconc0w 4y agoYou can also do this with potatoes. Repeated cooling/reheating is supposed to increase the RS levels, though I suppose to a limit. I imagine how effective this is varies with the individual, best way to tell how helpful this is for your particular situation would be to get a continuous blood glucose monitor since RS measurement is still not particularly easy to do or even standardized.
- vegetablepotpie 4y agoI am curious if this could be a way to increase the proportional nutrient content of rice, or if nutrient content will also be affected by an increase of RS. Because of rising CO2 levels in our atmosphere crops are going to become more starchy and contain proportionally less nutrients as a result [1]. We’re either going to need to find ways to increase nutrient intake or reduce the starchyness of the food we eat.

- jacknews 4y agoJust eat less. If this helped release calories more slowly, making rice healthier, that would be one thing, but we should not be wasting research effort, let alone agricultural output, to make food actually less nutritious, especially when people are still going hungry.
- jhanschoo 4y agoReducing calories from starch does not make rice less nutritious in the way that it matters...
- sacnoradhq 4y agoThis sounds of low repute since there's zero data or peer reviewed papers to back up these claims.
- Stealthisbook 4y agoI could see how this might be unpleasant. Making up to half the starch into something indigestible means it's still going somewhere...maybe unexpectedly and explosively.
- LorenPechtel 4y agoI wonder if this has anything to do with the fact that I find refrigerated rice very unappetizing even if it's rewarmed.
- crazygringo 4y agoThis is basically why fried was invented. To rewarm rice in a way that's tasty! But my suspicion is yes. It's the way rice firms up, hardens and separates in the fridge.
- quickthrower2 4y agoMy understanding is the body “estimates” the calories in what you eat to regulate hunger. Will regular eating of food like this make you hungrier long term as your body realises it was duped?
- dannyr 4y agoSo you boil water, add coconut oil then add rice. How would this work in a rice cooker?
- bakoo 4y agoI'd probably juat add the oil to the rinsed rice before dumping it into the pot.
- amanaplanacanal 4y agoThe important part is probably not the coconut oil, but the cooling in the fridge after cooking.
- wodenokoto 4y agoThat sounds horrible! That is like throwing out half the food!
- seba_dos1 4y agoSo I'll have to eat twice as much to not feel hungry?
