Rice nutrition statistics span food composition, dietary exposure, glycemic response and food-safety trade-offs. The figures below distinguish observed measurements, survey estimates, clinical-trial results, forecasts and FDA risk scenarios by population, period and geography.
Key Rice Nutrition Statistics
These are the most useful headline figures across the available evidence:
- Global primary-crop production reached 9.9 billion tonnes in 2023 worldwide, although this FAO total covers all primary crops rather than rice alone.
- Maize, wheat and rice together represented 91% of global cereal production in 2023, with FAO reporting the combined share rather than a separate percentage for rice.
- Cooked long-grain brown rice provided 123 kcal per 100 g in the USDA composition record, with values affected by variety and cooking.
- Cooked long-grain brown rice contained 25.58 g carbohydrate per 100 g in the USDA record, on a cooked-food basis.
- USDA listed 1.8 g total dietary fiber for cooked medium-grain brown rice per reference amount, a product-specific database entry.
- USDA listed 0.9 g total dietary fiber for cooked enriched parboiled white rice per reference amount, using the table’s stated reference basis.
- A peer-reviewed review described white rice as more than 90% starch, with the exact composition basis requiring care when comparing dry and cooked food.
- Tested white rice had a glycemic index of 82.5 in a randomized trial, reflecting one rice and preparation rather than all white rice.
- Tested brown rice had a glycemic index of 58.7 in the same trial, under the study’s specific testing conditions.
- Replacing white rice with brown rice lowered glycemic load by nearly 20% in the trial, which also involved accompanying whole cereals and legumes.
- The RCT baseline diet supplied 60.3% of energy from carbohydrates, among overweight Asian Indian participants.
- FDA estimated 94.1 ng/kg body weight/day of inorganic arsenic exposure from all rice sources for U.S. children younger than 1 year, using a 2003–2008 exposure model.
- FDA estimated 54.4 ng/kg body weight/day from rice for U.S. people aged 0–6 years, using modeled survey intake and concentration data.
- FDA’s rice and rice-product samples ranged from below 1 to 545 ppb inorganic arsenic, across products rather than a typical serving.
- Average inorganic arsenic in sampled rice grain ranged from 59 ppb for instant rice to 160 ppb for brown rice, with nonrepresentative category sampling.
- Cooking rice in excess water reduced average inorganic arsenic by 40% to 60%, depending on rice type and the cooking method.
- The same excess-water method reduced iron, folate, niacin and thiamine in enriched rice by 50% to 70%, according to FDA-reviewed studies.
- FDA modeled 39 rice-attributable lung and bladder cancer cases per million people over a lifetime, not observed cancer counts.
- A modeled 75-ppb inorganic-arsenic limit reduced risk by 17% to 79% depending on product, while also representing a counterfactual policy scenario.

Global Rice Production Context and Dietary Importance
FAO production statistics provide scale, but they do not measure rice intake, nutrient adequacy or the nutritional role of rice in individual diets. The 2023 figures are therefore agricultural context rather than direct nutrition outcomes.
- The FAO Agricultural production statistics 2010–2023 release reported 9.9 billion tonnes of global primary-crop production in 2023.
- Global primary-crop production was 3% higher in 2023 than in 2022 and 27% higher than in 2010, for the world’s combined primary crops.
- World cereal production increased by 61 million tonnes from 2022 to 2023, equivalent to a 2% increase in cereals overall.
- Maize, wheat and rice together accounted for 91% of total cereal production in 2023; the FAO source does not split that combined percentage among the three crops.
FAOSTAT agricultural production data harmonize information for 199 countries and territories in the 2010–2023 release. The broader FAOSTAT database covers food and agriculture statistics for more than 245 countries and territories from 1961 through the latest available year, but those coverage figures are not rice-intake estimates.
Brown and White Rice Nutrition Data
Food-composition statistics are item-specific. Water absorption, enrichment, variety and cooking method can change the values, so cooked, per-100-g and reference-amount bases should not be treated as interchangeable.
The USDA composition record used in the trial context reports the following for cooked long-grain brown rice:
| Nutrient | Amount per 100 g cooked | Food basis |
|---|---|---|
| Energy | 123 kcal | Long-grain brown rice |
| Carbohydrate | 25.58 g | Long-grain brown rice |
| Protein | 2.74 g | Long-grain brown rice |
| Fat | 0.97 g | Long-grain brown rice |
| Fiber | 1.6 g | Long-grain brown rice |
| Magnesium | 39 mg | Long-grain brown rice |
| Phosphorus | 103 mg | Long-grain brown rice |
| Manganese | 0.974 mg | Long-grain brown rice |
These composition values come from the peer-reviewed randomized controlled trial record and its cited USDA food-composition reference. They describe cooked long-grain brown rice, not every brown-rice variety or serving size.
The USDA National Nutrient Database total dietary fiber table provides separate reference entries:
- Cooked medium-grain brown rice contains 1.8 g total dietary fiber per reference amount.
- Cooked enriched parboiled white rice contains 0.9 g total dietary fiber per reference amount.
- Cooked white steamed Chinese-restaurant rice also contains 0.9 g total dietary fiber per reference amount.
The USDA table’s reference amount is specific to the database entry; it should not be equated automatically with a household serving. The restaurant entry is also a distinct preparation, so it is not a universal value for white rice.
Rice Carbohydrates, Fiber and Glycemic-Response Statistics
The peer-reviewed review on improving rice dietary fiber states that white rice is more than 90% starch, while noting that the exact basis matters when interpreting dry versus cooked composition. The same review cited a forecast that Southeast Asia diabetes prevalence would reach 120 million people by 2030; this is a forecast, not a current prevalence count or a causal estimate for rice.
The RCT involved overweight Asian Indian adults and compared controlled diet periods. Its baseline table reported 2,918 kcal/day of energy intake and 437.5 g/day of carbohydrate, with carbohydrates supplying 60.3% of energy.
| Trial measure | Baseline or test result | Population and period |
|---|---|---|
| Protein intake | 87.3 g/day; 11.9% of energy | Overweight Asian Indian participants, baseline |
| Dietary fiber | 38.6 g/day | Same trial population, baseline |
| Weighted glycemic index | 63.9 | Same trial population, baseline |
| Glycemic load | 251.5 units/day | Same trial population, baseline |
| White-rice GI | 82.5 | Trial test food |
| Brown-rice GI | 58.7 | Trial test food |
Replacing white rice with brown rice lowered glycemic load by nearly 20% in this intervention comparison. The paper attributes part of the difference to accompanying whole cereals and legumes, so the result should not be treated as proof that brown rice alone caused every observed change.
During the white-rice diet period, refined cereals contributed 72% of glycemic load. Whole cereals contributed 49.4% during the brown-rice period and 48.8% during the brown-rice-plus-legumes period, all within the trial’s diet composition.
Rice Nutrition by Age and Dietary Exposure
FDA’s exposure figures are modeled estimates based largely on NHANES/WWEIA 2003–2008 intake data and FDA concentration data. They are not direct measurements of every person’s intake or biomonitoring results.
The FDA Arsenic in Rice and Rice Products Risk Assessment Report estimated the following inorganic-arsenic exposures:
- U.S. infants younger than 1 year: 94.1 ng/kg body weight/day from all rice sources.
- U.S. males and females aged 0–6 years: 54.4 ng/kg body weight/day from rice, including 48.0 ng/kg/day from white rice and 7.1 ng/kg/day from brown rice.
- U.S. males and females aged 0–50 years: 31.9 ng/kg body weight/day from rice.
FDA estimated 62.4 to 216.8 ng/kg body weight per eating occasion, depending on rice type and age range. Among the NHANES/WWEIA race/ethnicity categories, 17.3% of people classified as “other” reported eating rice at least twice per day, and FDA noted a modeled daily exposure of 435 ng/kg body weight/day or more for that high-frequency scenario.
These results combine survey frequency, modeled concentrations and population definitions. NHANES did not distinguish varieties such as jasmine and basmati, which limits fine-grained comparisons among rice types.
Arsenic Levels and Rice-Cooking Nutrition Trade-Offs
FDA analyzed 481 rice-grain samples for its revised 2016 exposure assessment: 202 were collected by FDA at retail locations and 279 were supplied by the USA Rice Federation. FDA states that the sampling was not market-share weighted or statistically representative of all U.S. rice.
Across rice and rice products, reported inorganic-arsenic concentrations ranged from below 1 to 545 ppb. Average rice-grain concentrations ranged from 59 ppb for instant rice to 160 ppb for brown rice, but these are category averages from samples that were not statistically representative of the market.
FDA-reviewed cooking studies found that cooking rice in excess water, using 6–10 parts water to 1 part rice, reduced average inorganic arsenic by 40% to 60%, depending on rice type. The FDA consumer guidance also reports that the method reduced iron, folate, niacin and thiamine in enriched rice by 50% to 70%.
This creates a measurable nutrition trade-off: the method can lower arsenic in cooked rice while also reducing selected nutrients in enriched polished and parboiled rice. Nutrient losses vary by nutrient and preparation, so the percentages should not be read as one uniform loss for every cooking method.
Modeled Health Outcomes and Rice-Nutrition Policy Scenarios
FDA modeled lifetime cancer risk attributable to arsenic in all rice and rice products at 39 cases per million people in the general U.S. population. The modeled total comprised 10 bladder-cancer cases per million and 29 lung-cancer cases per million, compared with 90,000 lung and bladder cancer cases per million from all causes over a lifetime.
These are scenario outputs, not observed cancer counts. FDA also modeled one serving per day as producing 74 to 184 cases per million, depending on rice type.
The policy scenarios illustrate how assumptions change modeled risk and availability:
| Modeled inorganic-arsenic limit | Modeled risk reduction | Modeled availability effect |
|---|---|---|
| 150 ppb | 0%–23%, depending on product | Not supplied |
| 100 ppb | 2%–47%, depending on product | Availability could decrease 4%–93%, depending on rice type |
| 75 ppb | 17%–79%, depending on product | Not supplied |
FDA modeled eliminating rice exposure during infancy as reducing attributable lifetime cancer risk by 5.6%, and eliminating exposure during ages 0–6 as reducing it by 23.4%. A 50% reduction in childhood exposure was modeled to reduce lifetime cancer risk by 2.8% for infants and 11.7% for children aged 0–6.
The scenarios are counterfactual model outputs rather than clinical intervention results. Their interpretation depends on the exposure, concentration, product and age assumptions used in the FDA assessment.
