The Claim
The optimal cooking process reduces total dietary fiber content by 54.7% in white rice and by 24.8% in brown rice, and processing methods that reduce arsenic levels are associated with these measurable reductions in dietary fiber.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Cooking white rice in the most effective way to lower arsenic removes 54.7% of its dietary fiber, and cooking brown rice the same way removes 24.8% of its dietary fiber.
See the scientific wording
The optimal cooking process reduces total dietary fiber in 10DOP% white rice by 54.7% and in brown rice by 24.8%, indicating that processing methods that reduce arsenic also lead to measurable losses of beneficial nutrients.
When rice is cooked with excess water, the heat breaks open the grain structure, causing the outer layers to swell and dissolve. Fiber molecules that dissolve in water wash away with the cooking water, leaving less fiber behind in the cooked rice.
What the research says
1 studyThe study says you can cook rice to remove arsenic without losing too many good nutrients, which is the opposite of the claim that cooking always removes a lot of fiber. So the claim is too negative.
