Brown rice has more fiber, vitamins, and minerals in its bran layer, making it more nutritious than white rice.
It is known to be superior.
However, recently, brown rice has been found to contain higher levels of inorganic arsenic than white rice, which could be harmful to health.
The research results are shocking.
Arsenic in weapons is a heavy metal classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO).
Inorganic arsenic is rapidly eliminated from the human body and does not pose a major problem, but inorganic arsenic found in pesticides and insecticides can
There is a risk of cancer if consumed in large quantities or accumulated over a long period.
A research team at Michigan State University in the United States compared and analyzed arsenic exposure in brown rice and white rice through various research data.
As a result, inorganic arsenic was found to be present at quite high levels in the rice bran.
According to the research results, brown rice had approximately 24% higher total arsenic content and about 40% higher inorganic arsenic compared to white rice.
The arsenic concentration was found to be up to 10 times higher compared to white rice.
This is because brown rice contains rice bran, and arsenic is mostly concentrated and accumulated in the outer shell.
On the other hand, polished rice undergoes refining processes that remove the outer shell, resulting in a relatively lower arsenic concentration.
Brown rice is nutritionally superior to white rice, but it may contain higher levels of toxic substances.
In particular, the research team pointed out that attention is needed regarding children's intake of brown rice.
In adults, the likelihood of experiencing serious health risks due to differences in arsenic content between brown rice and white rice is not high, but
It can be a problem for children under 5 years old who have a relatively high food intake per weight.
Infants and young children aged 6 to 24 months who regularly consumed brown rice had...
The estimated exposure to arsenic was about twice as high.
To reduce worries, it is good to wash rice multiple times in water. Rinse the rice until the water becomes clear, or soak it in enough water, then discard the water and cook the rice with fresh water to lower the arsenic content.
----------------------------------
People who eat brown rice as their main food should wash it a few more times.
That's good~ They just say you shouldn't eat it after washing it a few times!
