Hidden danger in rice: it may contain arsenic

Why rice?

Arsenic naturally occurs in soil and groundwater, but mining, industrial activities, and pesticide use have further increased its presence. Because rice is grown in water-flooded fields, the plant absorbs significantly more arsenic compared to other grains.

Excessive arsenic intake over time increases the risk of cancer, high blood pressure, type 2 diabetes, and respiratory diseases.

How to reduce arsenic in rice?

Experts recommend several simple cooking methods to lower arsenic levels:

• Rinsing thoroughly: washing raw rice multiple times can reduce arsenic content by about 10%.

• Cooking in excess water: using six cups of water for one cup of rice and draining the excess afterward may lower arsenic levels by 40–60%.

• Rinsing after cooking: washing the cooked rice in clean water can further reduce risk.

Although white rice generally contains less arsenic than brown rice, it also has a lower nutritional value. For a balanced diet, it’s advisable to include other whole grains such as quinoa, millet, barley, bulgur, or amaranth.

What are the signs of arsenic poisoning?

Acute symptoms can include vomiting, numbness or tingling in the hands and feet, as well as dark spots on the palms and soles. While the concentration of arsenic in food rarely causes immediate poisoning, long-term exposure over years can pose serious health risks.
