This Instant Pot rice and grain cooker is mainly valued for making rice with a carb reducing mode and a stainless steel cooking basket. The rice comes out well when the water lines are used, the rice is washed first, and the finished batch rests before fluffing. The 12 quart size also helps with pot in pot cooking and cleanup stays simple. The main cautions are that the carb reduction claim is disputed, the cycle can take about 40 minutes, and some batches can burn, undercook, or turn mushy, especially back to back. A practical pick if you want a large, easy rice cooker with extra features.

  • Rice eaters who want a simple cooker for occasional batches, because it makes good rice and is easy to operate.

  • People managing glucose spikes with carb-reduced rice, because the preset can work well for brown rice and basmati and takes about 40 minutes.

  • People who refrigerate or freeze cooked rice for meal prep, because reheated rice can come out better and the starch benefit is a bonus.

  • Home cooks making pot-in-pot meals, because it fits a larger insert and can avoid burning with that method.

  • People expecting the carb-reducing cycle to reliably lower starch, because the collected water can stay nearly clear and the claim may not hold up.

  • Bulk meal preppers cooking back-to-back rice batches, because successive loads can undercook or heat unevenly.

  • Cooks who need rice to stay fresh and warm for long periods, because it does not do a good job keeping rice warm.

  • Anyone wanting a low-maintenance rice cooker, because it can take extra effort to assemble, use, and clean.

The Japanese government determined that these don't reduce carbs. All they do is make the grains of rice plumper and heavier, fooling you into eating less rice. So yeah, eating less rice means fewer sugar spikes. Please read my prior post for more details.

You might be kidding but it's actually true. The Japanese government determined that these don't actually reduce carbs. But they do make the cooked rice grains plumper and heavier. In other words, you end up eating fewer grains of rice. More details in my previous post.

The claim is false. The Japanese government tested these rice cookers and concluded that it's an illusion. I wrote more details in the post before this one.
Multi-quote is my friend.

I think it varies by the rice cooker too, I don't think the Instant Pot was part of those tests, but I thought they did find some had a few minor reductions if I remember correctly. At any rate, look at the YouTube video "Instant Rice Cooker. Really Reduces Carbs? Instant 20-Cup Rice Cooker, Rice & Grain Multi-Cooker" Someone wore a CGM and measured his blood glucose levels, the carb-reducing one was clearly lower. Make of that with what you will.

I've had this for almost a year. I paid $15 more for it on Amazon. We only used it to make rice. I rate it as, makes about 80% good rice as a $300+ rice cooker. It does not do a good job of keeping it fresh and warm. After a meal, the rice is moved into a glass storage container, to reheat later, and looks and tastes as right out of the cooker. For the price, it is well worth it. We have not had luck on the expensive units, lasting 3 years at most. If this one breaks at three years, at least we're not out a ton of money, and pissed off. Plus, its pretty cool looking, and simple to operate. And makes good rice. I dont use the carb reducer. To this Asian, that is just a marketing gimmick.

From reviews which saved me from buying. For any looking for this exact reason

"I grew up eating rice prepared using a traditional method. My mom in India would cook the rice in plenty of water and then drain the excess liquid once the rice was fully cooked. The drained water was noticeably cloudy because it contained starch removed from the rice. I expected this rice cooker to follow, or at least closely mimic, that same process. Unfortunately, it does not. The rice appears to be cooked mainly with steam, and the water collected underneath remained almost completely clear. That makes me question how much starch is actually being removed. The concept sounds promising, and the cooker may work well as a regular rice cooker. However, based on what I observed, I am not convinced that it produces truly low-carb rice. If the collected water contains little or no visible starch, it seems that most of the starch is still remaining in the cooked rice. This cooker also requires more effort to assemble, use, and clean than a regular rice cooker. Considering that I could not see clear evidence of starch removal, the extra work does not seem worthwhile when other rice cookers are much simpler and more convenient to use."

Yes, blood glucose is lower because you're eating less rice. It's that simple. You'd get the same effect if you eat the identical number of grains of cooked the normal way. Basically, the Japanese government determined that all these do is to make each grain absorb more water (hence the extra water and time needed). Absorbing more water makes each cooked grain plumper and heavier than rice cooked the normal way. As a result, if you eat 2 cups of cooked rice, you're actually eating fewer grains than rice cooked the regular way (because each grain is bigger). Similarly, eating 8oz of this cooked rice means eating fewer grains than normally cooked rice because each grain is heavier.

It's really that simple. The problem with YouTube, Facebook, TikTok, etc videos is that they're not done by scientists who control every variable. In this case it's as simply as counting how many grains of rice is actually eaten. And that was exactly what the Japanese government did.

So no, these don't lower the carbs of rice. All they do is fool you into eating less rice. But you'll likely feel hungry sooner so they're very unlikely to help with dieting. A much cheaper and scientifically proven way to lower the carb intake is to refrigerate the cooked rice overnight. That converts some of the starch into resistant starch which will not be metabolized by the body.

FYI, that video conveniently turned off comments. Gee, I wonder why? Is it so that gullible viewers use his affiliate link to make him money?
