Yes, jasmine rice is a high glycemic food. In testing, white jasmine rice consistently scores between 96 and 116 on the glycemic index, well above the 70 threshold that marks a food as high GI. This holds true whether the rice is grown in Thailand or the United States. If you’re watching your blood sugar, that number matters, but there are practical ways to bring the impact down.
Why Jasmine Rice Ranks So High
The glycemic index of any rice variety depends largely on the type of starch it contains. Starch comes in two forms: one that digests slowly and one that digests quickly. Jasmine rice is unusually low in the slow-digesting type, containing only about 12 to 17% amylose by weight. That’s less than most other rice varieties. The rest is the fast-digesting form, amylopectin, which your body breaks down rapidly into glucose.
This starch profile is also what gives jasmine rice its signature sticky, soft texture. The same quality that makes it pleasant to eat is what sends blood sugar up quickly. Rice varieties with more amylose tend to be firmer, less sticky, and gentler on blood sugar.
How Jasmine Compares to Other Rice
Not all rice behaves the same way in your body. Basmati rice, another popular long-grain white variety, scores significantly lower. Depending on cooking time and preparation, basmati GI values typically range from the low 50s to the upper 60s. Some studies put it as low as 52. That places most basmati rice in the low to medium GI range, roughly half the glycemic impact of jasmine.
Brown rice varieties generally fall in the medium range as well, with GI values around 50 to 65 in most studies. Wild rice and red rice perform similarly. Even brown basmati rice, despite being whole grain, can creep into the 70s depending on how it’s cooked, so the variety of rice matters as much as whether it’s white or brown.
Jasmine rice also triggers a stronger insulin response than basmati. In one study measuring insulin index scores across ethnic groups, jasmine rice averaged 76 compared to 57 for basmati. That means jasmine rice demands more insulin from your pancreas to process the same amount of carbohydrate.
Cooling and Reheating Lowers the Spike
One of the simplest ways to reduce the blood sugar impact of jasmine rice is to cook it, refrigerate it for about 24 hours, and then reheat it. This process converts some of the fast-digesting starch into resistant starch, a form your body can’t break down as quickly. In a study testing this approach with white rice, the cooked-cooled-reheated rice produced a meaningfully lower glycemic response than freshly cooked rice.
This is why leftover rice and fried rice made from day-old rice are slightly better options from a blood sugar perspective. The resistant starch that forms during cooling partially survives reheating, so you still get the benefit even after warming the rice back up.
What You Eat With It Matters
Jasmine rice is rarely eaten alone, and that works in your favor. Pairing it with protein, fat, or fiber slows down digestion and blunts the glucose spike. A plate of jasmine rice with grilled chicken, vegetables, and a drizzle of oil will produce a very different blood sugar curve than a bowl of plain rice.
Vinegar also has a measurable effect. Research on high-carb meals found that adding vinegar (the equivalent of about one to two tablespoons) reduced both blood glucose and insulin responses in a dose-dependent way. The more acetic acid included, the lower the spike. This is relevant if you’re eating jasmine rice in dishes that include pickled vegetables, soy-vinegar dipping sauces, or a splash of rice vinegar.
The Diabetes Plate Method offers a useful visual guide: fill half a 9-inch plate with non-starchy vegetables, one quarter with protein, and only one quarter with a carbohydrate like rice. That simple ratio keeps the portion of jasmine rice moderate enough to limit its glycemic impact.
Lower GI Swaps Worth Trying
If you eat rice regularly and blood sugar is a concern, switching varieties can make a real difference. Basmati rice is the closest swap in terms of flavor and texture for many dishes, and its GI runs 40 to 50 points lower than jasmine in some comparisons. Brown rice, red rice, and wild rice all tend to land in the medium GI range as well.
Brown jasmine rice exists too, and while specific GI data on it is limited, whole grain versions of rice generally score lower than their white counterparts because the bran layer slows digestion. Expect brown jasmine rice to fall somewhere in the medium GI range rather than the high range of white jasmine, though it likely won’t drop as low as brown basmati.
For the biggest reduction, mixing jasmine rice with a lower GI grain like wild rice, barley, or cauliflower rice dilutes the overall glycemic load of the meal without completely changing the eating experience.
