The Claim
Cooking parboiled rice with a 1:6 water-to-rice ratio after five washes reduces arsenic levels by an average of 33% compared to cooking with a 1:2 water-to-rice ratio, but also reduces selenium by 49%, zinc by 17%, and manganese by 22% in Bangladesh.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Cooking parboiled rice with six times its volume in water after five washes lowers arsenic by 33% but also reduces selenium by 49%, zinc by 17%, and manganese by 22% compared to cooking with two times its volume in water.
See the scientific wording
Cooking rice with a 1:6 water-to-rice ratio after five washes reduces arsenic levels by an average of 33% compared to cooking with a 1:2 ratio, but also reduces essential nutrients such as selenium by 49%, zinc by 17%, and manganese by 22%, indicating a trade-off between reducing toxic element exposure and preserving nutritional value in parboiled rice consumed in Bangladesh.
When rice is washed multiple times and cooked with a large amount of water, arsenic and essential minerals like selenium, zinc, and manganese dissolve into the water and are poured away, reducing their levels in the cooked rice.
What the research says
1 studyWashing rice five times and cooking it with six times as much water removes about a third of the arsenic, but it also washes away nearly half the selenium and big chunks of zinc and manganese — so safer rice means less nutrition.
