White rice: how much you eat decides what the data says

In a meta-analysis of randomized trials, whole-grain rice lowered the blood glucose area after a meal by 730 mg/dL (40.5 mmol/L) x min compared with white rice (95% CI 21.3 to 59.6). Those were single-meal tests in mostly healthy people, and they say nothing about the long run. Over years, the diabetes link is observational and tracks dose. Across 352 384 people in seven cohorts from four articles, each daily serving of white rice went with 11 percent higher risk of type 2 diabetes (RR 1.11, 1.08 to 1.14). The top intake in Asian cohorts carried 55 percent higher risk, with no significant link in Western cohorts, where people ate one to two servings a week. In the PURE study of 132 373 adults in 21 countries, 450 g or more of cooked rice a day went with 20 percent higher diabetes risk than under 150 g. The link was 61 percent in South Asia and not significant in China, gaps that may reflect what rice is eaten with and how active people are.

The bottom line

Boiled long grain white rice gives 131 calories, 31.1 g of starch, 2.8 g of protein and 0.5 g of fiber per 3.5 oz (100 g) in the UK tables. The US dietary survey weighs one cup of cooked rice at 158 g, which recalculates to about 207 calories. Milling rice to white removes 75 to 90 percent of its thiamine, niacin, vitamin B6 and vitamin E, according to WHO background resting on a single reference, and enriched US rice puts some of that back. Across 15 laboratory studies, cooking lowered arsenic in the grain by 0.04 mg/kg on average (95% CI 0.03 to 0.05), with rinsing and parboiling ranked most effective. That measures the rice and not the people eating it, and cooking in excess water also washes some B vitamins out of enriched rice. How you eat the rice shifts the glucose curve in small trials. In 18 young women, vegetables eaten before boiled white rice lowered glucose and insulin at 30 and 60 minutes, even when the meal took 10 minutes. In 12 healthy women, drinking 6.8 fl oz (200 mL) of green tea with 5.3 oz (150 g) of white rice raised post-meal glucose above rice alone by speeding stomach emptying. In 10 healthy adults, brown rice left the stomach more slowly than white. All three were single meals, and none of the abstracts gives the size of the effect. Heart disease is where the fear outruns the data. Pooling seven cohorts for each outcome, white rice showed no link with cardiovascular disease (HR 0.93, 0.86 to 1.00) or stroke (HR 1.03, 0.93 to 1.14), with unmeasured confounding likely, and that null does not cancel the diabetes signal. A meta-analysis of 12 cohort studies tied high rice intake to 40 percent more chronic disease in women and 13 percent lower mortality in men. Those sex splits rest on few studies with high heterogeneity, and the overall estimates were null. Among 1565 Japanese adults with type 2 diabetes, the link between rice and obesity in older women lost significance once fiber density was accounted for, a cross-sectional result that points at the rest of the diet. The caution with evidence behind it is arsenic for babies. In 2016 FDA proposed an action level of 100 parts per billion of inorganic arsenic in infant rice cereal, a limit that applies to infant cereal and not to table rice. In a US survey of 2635 children under two, 58 percent of babies aged 6 to 12 months ate rice or rice foods on a given day, about 12 g on average. That was one day of recall, and it counts rice eaten and not arsenic taken in. We found no card on rice in pregnancy or with medicines.
