Choose wisely, eat safely: Arsenic and rice
Arsenic is a naturally occurring element that can be found in small amounts in soil and water. As a result, it can also be present in rice, particularly when grown in areas with high arsenic levels in the soil or water.
While arsenic is toxic in high concentrations, the levels found in rice are generally considered safe for consumption. However, it's important to be aware of the potential for arsenic contamination and take steps to minimize exposure.
Recent research has revealed higher-than-expected levels of inorganic arsenic in rice cereal and rice pasta. This poses a potential health risk for infants and children.
The Food and Drug Administration's 2013 (FDA) data on 656 processed rice products showed that just one serving of rice cereal or rice pasta could exceed a child's recommended weekly arsenic intake. Additionally, rice cakes and rice drinks can also contain significant amounts of arsenic.
The FDA has established safe limits for arsenic in rice. These limits are based on scientific evidence that shows that consuming rice at or below these levels does not pose a significant health risk to most people. However, it's important to note that some individuals, such as young children and pregnant women, may be more sensitive to the effects of arsenic.
Rice tends to have higher levels of inorganic arsenic compared to other foods. The specific levels of arsenic in rice can vary depending on several factors, including the type of rice, the growing conditions, and the processing methods used.
Brown rice tends to have higher levels of arsenic than white rice. This is because the arsenic is concentrated in the outer layers of the grain, which is removed during the processing of white rice. However, it's important to note that white rice is not completely free of arsenic. White rice can be contaminated with arsenic, especially if it is grown in areas with high levels of arsenic in the soil or water or fertilized with arsenic-containing fertilizers. The arsenic in white rice is typically lower than in brown rice, but it's still present in small amounts.
Basmati rice from California, India, and Pakistan, as well as sushi rice from the U.S., generally have lower arsenic content. Based on new data, adults can safely consume up to 4.5 servings of these low-arsenic rice varieties per week, while children can have 2.75 servings.
The processing methods used to produce rice can also influence arsenic levels. Rice that is processed using older methods may be more likely to retain higher levels of arsenic. However, modern rice processing methods can help to reduce arsenic levels by removing the outer layers of the grain, which tend to have higher concentrations of arsenic.
Many countries and organizations have established limits for inorganic arsenic in food products. For example, the European Union currently maintains a limit of 0.1 milligrams of inorganic arsenic per kilogram of rice.
While rice grown in countries with strict regulations on arsenic levels is generally considered safer, it's important to be aware that arsenic can be naturally present in the soil and water, even in countries with strict regulations. This is because arsenic is a naturally occurring element that can be found in various geological formations, such as volcanic rocks and minerals. Additionally, arsenic can be introduced into the environment through human activities, such as mining, industrial processes, and the use of pesticides. As a result, rice grown in any region can potentially be contaminated with arsenic, although the levels of contamination can vary widely depending on the specific location and growing conditions. For example, rice grown in regions with volcanic soil or near mining sites may be more likely to have higher levels of arsenic.
If you are concerned about your exposure to arsenic from rice, there are several things you can do to minimize your risk.
Organic rice is less likely to be treated with pesticides or other chemicals that can increase arsenic levels. While organic certification does not guarantee that rice is completely free of arsenic, it can be a good way to reduce your exposure to harmful chemicals.
Soaking and rinsing rice before cooking can help reduce arsenic levels by up to 25%. This is because arsenic can be water-soluble, and soaking and rinsing can help to remove some of the arsenic from the rice. Additionally, cooking rice in a ratio of 6 parts water to 1 part rice can also help reduce arsenic levels.
Here's a step-by-step guide on how to soak and rinse rice before cooking:
- Rinse the rice thoroughly under cold water. This will help to remove any surface contaminants and loosen any grains that may be stuck together.
- Fill a large bowl with water and add the rice. The water should cover the rice by at least 2 inches.
- Soak the rice for 30 minutes to 1 hour. Soaking the rice allows the water to penetrate the grains and helps to leach out any arsenic that may be present.
- Drain the water and rinse the rice again. This will help to remove any remaining arsenic that may have been leached from the rice during the soaking process.
- Cook the rice as directed. You can cook the rice in a rice cooker, or on the stove top.
By following these steps, you can help to reduce the amount of arsenic in your rice by up to 25%. However, it's important to note that soaking and rinsing rice is not a foolproof way to eliminate all arsenic.
Diversify your diet. By eating a variety of grains, you can help to ensure that you are not consuming excessive amounts of arsenic from any one source. Amaranth, buckwheat, millet, and polenta/grits generally have negligible levels of inorganic arsenic. Bulgur, barley, and farro also contain low levels of arsenic. While generally low, quinoa can have varying arsenic levels.
Ayurveda recognizes the potential health risks associated with long-term arsenic exposure, categorizing it as dushivisha or chronic sub-clinical poisoning. Panchakarma can help eliminate toxins from the body. Ayurvedic remedies and detoxification therapies can help mitigate the effects of arsenic exposure.
If you are particularly concerned about your exposure to arsenic, you can have your rice tested for arsenic levels. Some laboratories offer testing services for arsenic in food.
Keep up to date on the latest information about arsenic in rice. The U.S. Food and Drug Administration (FDA) and other health organizations regularly monitor arsenic levels in food and provide guidance to consumers.
It's important to note that the risk of health problems from arsenic exposure is very low for most people. However, if you have concerns about your exposure to arsenic, it's a good idea to talk to your doctor.
