Why Arsenic is a Concern in Rice
Arsenic is a naturally occurring element present in soil and groundwater, but certain agricultural practices can increase its presence. Rice plants are particularly efficient at absorbing arsenic from their environment, especially when grown in flooded paddy fields. The inorganic form of arsenic found in rice is more toxic than the organic form, posing health risks with long-term exposure. Chronic exposure has been linked to various health issues, including an increased risk of certain cancers, type 2 diabetes, and cardiovascular disease.
The Safest Rice Varieties for Low Arsenic
Not all rice is created equal when it comes to arsenic content. Factors like where the rice is grown and how it is processed play a significant role. Choosing specific varieties and origins can help reduce your exposure.
Low-Arsenic Options
- Basmati Rice (from India or Pakistan): Consumer Reports and other studies consistently identify white basmati rice from these regions as having lower levels of inorganic arsenic.
- Jasmine Rice (from Thailand): Similar to Basmati, Thai jasmine rice is also a strong low-arsenic contender.
- California-grown Rice: For domestic options, rice from California—including white basmati and sushi rice—tends to have significantly lower arsenic levels than rice grown in states like Texas, Louisiana, and Arkansas. Some growers in California, such as Lundberg Family Farms, also provide publicly available arsenic test results.
- White Rice vs. Brown Rice: As a general rule, white rice has lower arsenic levels than brown rice because the polishing process removes the outer bran layer where arsenic tends to accumulate. While brown rice is more nutrient-dense, the higher arsenic content is a trade-off to consider for frequent consumers. Choosing a low-arsenic white variety or a low-arsenic brown basmati from a known region is a balanced approach.
Cooking Methods to Reduce Arsenic
Even with the safest rice, cooking techniques can further lower its arsenic content. Using a high water-to-rice ratio is the most effective method.
The 'Pasta Method'
- Bring a large pot of water (about 6 to 10 cups of water for every 1 cup of rice) to a rolling boil.
- Add the rice and cook until it is tender, much like cooking pasta.
- Drain the excess water thoroughly. This process can remove up to 60% of the rice's inorganic arsenic.
Soaking and Rinsing
While rinsing rice before cooking can offer a minimal reduction in arsenic, soaking the rice for 30 minutes to overnight and then draining and rinsing can be more effective.
The Cooking Water is Key
Using clean, arsenic-free drinking water for cooking is crucial. If your tap water has elevated arsenic levels, it can increase the arsenic content of your cooked rice. Check your local water quality or use a quality filter.
Alternative Low-Arsenic Grains
For those who consume a lot of rice, diversifying your diet with other low-arsenic grains is a highly effective strategy. These grains absorb significantly less arsenic from the soil than rice and are nutritious alternatives.
Safe Grain Alternatives
- Quinoa: A gluten-free grain that is a complete protein source and very low in arsenic.
- Bulgur: A quick-cooking whole wheat product with negligible arsenic levels.
- Amaranth and Millet: Ancient gluten-free grains that are excellent choices for reducing overall arsenic intake.
- Farro and Barley: Two more whole grains with very low arsenic contamination.
Low-Arsenic Rice and Grain Comparison
| Feature | California White Basmati | Brown Rice (General) | Quinoa | Thai Jasmine Rice |
|---|---|---|---|---|
| Arsenic Level | Low | Higher (concentrated in bran) | Very Low | Low |
| Nutritional Value | Lower fiber/minerals, often enriched | Higher fiber, vitamins, and antioxidants | High in protein and minerals | Similar to other white rice |
| Source Dependency | Reliant on California farming standards | Varies widely by region | Less soil-dependent for arsenic levels | Reliant on growing region |
| Cooking Method | Can be cooked with standard absorption | Requires more water for arsenic reduction | Standard cooking methods | Can be cooked with absorption or excess water |
| Best For | Lower-risk white rice option | Nutrient boost if source is verified low-arsenic | Gluten-free, high-protein alternative | Flavorful, low-arsenic white rice |
Special Considerations for Vulnerable Groups
For certain groups, such as infants, pregnant women, and frequent consumers, the risks associated with arsenic are higher and warrant extra caution.
Infants and Young Children
Infant rice cereal and snacks are a common source of exposure. Experts recommend diversifying the baby's diet with low-arsenic options like baby oatmeal, barley, or other non-rice purees. The FDA has set guidance for inorganic arsenic levels in infant rice cereal, but variety remains key.
Pregnant Women
Studies show that maternal rice consumption during pregnancy is linked to higher arsenic concentrations in infants. Pregnant women should be mindful of their rice intake and focus on diversifying grains and using safer cooking methods.
Conclusion: Making Safer Choices
While it is virtually impossible to find any rice with zero arsenic, you can significantly minimize your exposure through strategic choices. The safest rice options typically include white basmati from India or Pakistan, Thai jasmine rice, and California-grown white and sushi rice. Adopting a 'pasta-style' cooking method can also reduce arsenic content by up to 60%. Perhaps most importantly, varying your grain intake with low-arsenic alternatives like quinoa, bulgur, and millet is the best long-term strategy for a healthier, more balanced diet. By understanding the risks and implementing these simple strategies, you can continue to enjoy rice safely as part of a varied and nutritious diet.

How to Check Your Water for Arsenic
If you use well water for cooking, it is crucial to have it tested for arsenic contamination. The Environmental Working Group (EWG) also offers resources for checking public water quality. If high arsenic levels are detected, consider installing a water filter or using bottled water for cooking rice to minimize absorption.
A Note on Organic Rice
Contrary to popular belief, organic rice is not necessarily lower in arsenic than conventional rice. Arsenic is absorbed from the soil, so the contamination depends on the growing location, not whether the rice was grown with pesticides. Some historical arsenic-based pesticides may also remain in the soil of organic farms.
