How to Cook Rice to Remove the Most Arsenic

It’s downright Victorian, but alas, our rice is rife with arsenic – here’s how to enjoy the grains without the poison.

Victorian women used magical potions made from ammonia, mercury and lead to achieve their wan glow. And although murder by poison was all the rage and feared by many, there was also no shortage of products like Arsenic Complexion Wafers, “simply magical” confections consumed to improve “even the coarsest and most repulsive skin and complexion.”

Thankfully we’re no longer being lured into eating arsenic-laced cookies. But arsenic-laced rice? That’s a different story. It’s not new news that our rice is spiked with this toxic element nor is it an urban myth. Even the FDA chimes in on the topic, noting that arsenic is an element in the Earth’s crust, and is present in water, air, and soil. The agency explains:

Rice has higher levels of inorganic arsenic than other foods, in part because as rice plants grow, the plant and grain tend to absorb arsenic more readily than other food crops. In April 2016, the FDA proposed an action level, or limit, of 100 parts per billion (ppb) for inorganic arsenic in infant rice cereal. This level, which is based on the FDA’s assessment of a large body of scientific information, seeks to reduce infant exposure to inorganic arsenic. The agency also has developed advice on rice consumption for pregnant women and the caregivers of infants.

But as the popularity of rice and its products (rice cakes, rice milk, et cetera) are on the rise, so should concern be for people beyond infants and pregnant women who eat rice on a regular basis. It can be quite toxic and in the European Union, arsenic is classified as a category 1 carcinogen, meaning that it’s known to cause cancer in humans.

Rice has around 10 to 20 times more arsenic than other cereal crops because it is grown in flooded fields which make it much easier for arsenic to leave the soil and enter the rice, notes an article by the BBC program Trust Me I’m a Doctor. For the program, Michael Mosley met Prof Andy Meharg from Queen’s University, Belfast, who is an expert on the topic of rice and rice products.

Where the arsenic is high and low

• Basmati rice contains lower levels than other rice.
• Brown rice usually contains more arsenic than white rice (because of the husk).
• Growing rice organically doesn’t make a difference to levels.
• Rice cakes and crackers can contain levels higher than in cooked rice.
• The levels of arsenic found in rice milk far exceed the amounts that would be allowed in drinking water.

Mosley and Meharg did some fancy footwork to test various arsenic levels as determined by cooking methods. Arsenic leaves the rice for the water when cooking – but if you cook your rice until it’s not swimming or use a rice cooker, the arsenic goes right back into the rice when all is said and done. The solution? Use more water than is required to cook the rice so that there is a leftover reservoir of it where the arsenic can remain. The team explains that when they used 5 times as much water as rice when cooking, only 43% of the arsenic remained in the rice. When they also soaked the rice overnight before cooking, only 18% of the arsenic remained in the rice.

How to cook rice to remove the most arsenic

  • Soak your rice overnight – this opens up the grain and allows the arsenic to escape.
  • Drain the rice and rinse thoroughly with fresh water.
  • For every part rice add 5 parts water and cook until the rice is tender – do not allow it to boil dry.
  • Drain the rice and rinse again with hot water to get rid of the last of the cooking water.

And hey, when you’re done you can even use that drained arsenic water to splash on your face for that petal-perfect Victorian pallor. Or not.

between the dyes and preservatives in everything we consume this is no big shocker I guess it's best to not consume too much rice at one sitting and we're just draining the arsenic back into the water system so round and round it goes

how do you drain the rest of the water after cooking w/o it becoming soggy?

I had no idea that there was arsenic in rice.

Have heard about the arsenic contamination, good to hear there's a means to remove it. Thanks.

Good to hear Basmati is lower, not so good about the brown rice though. I do rinse my rice well, but I didn't realize about the arsenic. I love my rice cooker, so I would like to be able to continue using it. Perhaps soaking the rice overnight first would help a bit, even if I didn't use the 5:1 water ratio. I could also give that ratio a try in my rice cooker and see how that goes. Doesn't hurt to try!
