Yellow rice: white rice with a color, and usually a salted mix

The turmeric in yellow rice is sometimes credited with steadying blood sugar. The trial behind that idea gave 16 healthy volunteers a single 180 mg curcumin tablet before a standard meal, and their rise in blood glucose was 36% smaller than with placebo. That was one dose of a tablet. No trial has measured blood glucose after yellow rice itself. What the dish reliably carries is salt. The US food survey database puts a cup cooked with fat at about 572 mg of sodium, a figure calculated for a typical seasoned mix, so rice colored at home with turmeric or saffron and no salted mix will be far lower. Underneath the color it is white rice. Across seven cohort analyses of 352,384 people, each extra daily serving of white rice was associated with an 11% higher risk of type 2 diabetes (relative risk 1.11, 95% CI 1.08 to 1.14). That is an association, clearest in Asian populations, and the turmeric or saffron in yellow rice was never studied in it.

As people eat it, per 3.5 oz (100 g)

How much is actually in it

• Cooked yellow rice in the US food survey database carries about 350 mg of sodium per 3.5 oz (100 g), so one cup with fat added holds about 572 mg. — USDA FNDDS records Yellow rice, cooked, fat added (FDC 2708421) and Yellow rice, cooked, no added fat (FDC 2708420) (n = 2 records) Evidence E source
  Sodium 351 mg per 3.5 oz (100 g) (fat added) and 340 mg per 3.5 oz (100 g) (no added fat); 572 mg per 163 g cup and 537 mg per 158 g cup

What a real portion looks like

• Cooking yellow rice with fat moves a cup from about 139 to 168 calories, and one cup of cooked yellow rice weighs 5.6 to 5.7 oz (158 to 163 g). — USDA FNDDS records Yellow rice, cooked, fat added (FDC 2708421) and Yellow rice, cooked, no added fat (FDC 2708420) (n = 2 records) Evidence E source
  Energy 103 calories per 3.5 oz (100 g) with fat added vs 88 calories without; monounsaturated fat 1.068 g vs 0.11 g per 3.5 oz (100 g); 1 cup 163 g vs 158 g

What your body absorbs

• Curcumin is absorbed far better from turmeric than as pure curcumin powder: with 400 mg curcumin in a meal with cream, peak blood curcumin was 8.4 ng/ml from turmeric powder against 0.19 ng/ml from curcumin powder. — Healthy men after an overnight fast, crossover, each meal holding 400 mg curcumin as curcumin powder, turmeric powder or fresh grated turmeric with mashed potatoes and cream Evidence B source
  Plasma curcumin Cmax 8.4 ng/ml (95% CI 4.4 to 12.48) turmeric powder, 4.9 ng/ml (2.2 to 7.5) fresh turmeric, 0.19 ng/ml (-0.08 to 0.47) curcumin powder

What cooking and storage change

• Boiling rice in excess water and draining it cut inorganic arsenic by 40% in long grain white rice in FDA laboratory tests, but also cut added iron, folate, niacin and thiamin by 50 to 70%, while rinsing barely changed arsenic. — Multiple rice varieties cooked rinsed and unrinsed with varying amounts of water in a US FDA laboratory Evidence D source
  Inorganic arsenic down 40% (long grain polished), 60% (parboiled), 50% (brown) with excess water; enrichment nutrients down 50-70% in enriched polished and parboiled rice

What it does to your health

• Yellow rice is white rice underneath, and cohort data link each extra daily serving of white rice to an 11% higher risk of type 2 diabetes, most clearly in Asian populations. — 352,384 participants in seven prospective cohort analyses from Asian and Western populations, followed 4 to 22 years, 13,284 incident cases of type 2 diabetes (n = 352384) Evidence C source
  RR 1.11 (95% CI 1.08 to 1.14) per serving a day; highest vs lowest intake RR 1.55 (1.20 to 2.01) in Asian and 1.12 (0.94 to 1.33) in Western populations

Safety, limits and interactions

• CDC notes that B. cereus is often present in uncooked rice and its spores may survive cooking. If cooked rice is then held at room temperature, the bacteria multiply and make a heat-stable toxin that can survive brief heating such as stir frying. — General population (home food handling) (n = -) Evidence E source
  Spores survive cooking, toxin forms at room temperature and survives brief reheating
• In a 1994 cholera outbreak among cruise passengers, illness was associated with eating yellow rice at one Bangkok buffet restaurant. — 630 cruise ship passengers to Southeast Asia, surveyed by questionnaire with serum testing of those reporting diarrhea (n = 630) Evidence C source
  6 confirmed cases of Vibrio cholerae O139, illness associated with yellow rice at one buffet (P = .005)

What people believe that the data does not support

• The blood sugar benefit tied to curcumin comes from a 180 mg tablet before a meal: in 16 healthy volunteers it cut the rise in blood glucose by 36% against placebo, which says nothing yet about turmeric used to color rice. — 16 healthy volunteers, randomized crossover, single dose of placebo, 180 mg curcumin, fish oil or both before a standard meal, one week apart (n = 16) Evidence B source
  Glucose AUC reduced 36% with curcumin vs placebo (P = 0.003); insulin AUC reduced 26% (P = 0.01)

Who this works differently for

• In one case report, doctors hypothesized that a 12-year-old girl's fixed drug eruption was caused by her family switching from natural achiote to a commercial yellow rice dye containing tartrazine. — One 12-year-old girl recently moved from Ecuador to the United States, with no medication exposure (n = 1) Evidence D source
  Fixed drug eruption attributed by history to tartrazine (Yellow 5) in a commercial dye mix used for yellow rice

The bottom line

Cooking the rice with fat moves a cup from about 139 to 168 calories in the same survey database, which assumes a standard amount of fat. Real side portions often run larger than one cup. Turmeric does deliver more curcumin to the blood than purified curcumin powder does. In a crossover study in healthy men, a meal of mashed potato and cream holding 400 mg of curcumin gave a peak of 8.4 ng/ml (95% CI 4.4 to 12.5) from turmeric powder and 0.19 ng/ml from curcumin powder. The meal was potato, the dose was far above what a portion of yellow rice holds, and the abstract does not say how many men took part. In FDA laboratory tests, boiling long grain white rice in excess water and draining it cut inorganic arsenic by 40%, and also washed out 50 to 70% of the added iron, folate, niacin and thiamin. Rinsing barely changed arsenic. Yellow rice is usually cooked by absorption in a set amount of water or stock, which keeps both the arsenic and the added vitamins. We hold no card on arsenic from rice for infants, young children or pregnancy, so this page cannot say how often those groups can eat it. Two cautions come from single events. In a 1994 outbreak investigation of 630 cruise passengers, 6 confirmed cholera cases were linked to yellow rice eaten at one Bangkok buffet, which points to how that rice was handled rather than to the dish itself. This page holds no card on how cooked rice should be cooled and stored. A 12-year-old girl developed a fixed drug eruption after her family switched from natural achiote to a commercial yellow rice dye containing tartrazine, though that cause was inferred from her history and never tested. We have no card on yellow rice in pregnancy or alongside medicines.
