Arsenic isn’t just thought of to be a carcinogen; it’s additionally designated as a “nonthreshold carcinogen, which means that any dose, regardless of how small, carries some most cancers threat”—so there actually isn’t a “secure” stage of publicity. On condition that, it could be cheap to “use the conservative ALARA” method, decreasing publicity As Low As Reasonably Achievable.
I’ve a low bar for recommending folks keep away from meals that aren’t notably health-promoting within the first place. Keep in mind when that acrylamide story broke, in regards to the chemical discovered concentrated in french fries and potato chips? (See my video Acrylamide in French Fries for extra.) My take was fairly easy: Look, we’re unsure how unhealthy this acrylamide stuff is, however we’re speaking about french fries and potato chips, which aren’t wholesome anyway. So, I had no drawback provisionally bumping them from my listing of yellow-light meals into my red-light listing, from “decrease consumption” to “ideally keep away from on a day-to-day foundation.”
One might apply the identical logic right here. Junk meals made out of brown rice syrup, rice milk, and white rice usually are not simply processed meals, but additionally arsenic-contaminated processed meals, so they might belong within the purple zone as red-light meals we should always keep away from. What about one thing like entire brown rice? That’s harder, as a result of there are professionals to assist outweigh the cons. I focus on this in my video Is White Rice a Yellow-Light or Red-Light Food?, the place you possibly can see a graphical depiction of my visitors gentle meals system at 0:49.
The rice trade argues that the “many well being advantages of rice consumption outweigh any potential threat,” which is similar sentiment you hear popping out of Japan in regards to the arsenic-contaminated seaweed hijiki: Sure, “the most cancers threat posed by hijiki consumption exceeds this acceptable [cancer risk] stage by an element of 10,” an order of magnitude, however the Japanese Ministry of Well being stresses the “attainable well being advantages,” equivalent to numerous fiber and minerals, as if hijiki was the one weed within the sea. Why not select any of the different seaweeds and get all the advantages with out the arsenic? So, when the rice trade says the “many well being advantages of rice consumption outweigh any potential threat,” it’s as if brown rice was the one entire grain on the planet. Can’t you get the entire grain advantages with out the dangers by consuming oatmeal, barley, or quinoa as a substitute? Or, is there some distinctive profit to rice, such that we actually ought to attempt to hold brown rice in our weight loss plan?
Shopper Reviews really useful transferring rice to the yellow-light zone—in different phrases, don’t essentially keep away from it fully, however average your consumption. The rice trade, in a truth sheet entitled “The Shopper Reviews Article is Flawed,” criticized Shopper Reviews for warning folks in regards to the arsenic ranges in rice, saying “[t]here’s a physique of scientific proof that establishes…the dietary advantages of rice consumption; any evaluation of the arsenic ranges in rice that fails to take this info under consideration is inherently flawed and really deceptive.” The rice trade cites two items of proof. First, it asserts that rice-consuming cultures are typically more healthy, however is that due to, or regardless of, their white rice consumption? And what about the truth that rice-eating Individuals are typically more healthy? Maybe, however additionally they are inclined to eat considerably much less saturated fats. So, as soon as once more, how do we all know whether or not it’s due to—or regardless of—the white rice?
The rice trade might have cited the examine I focus on at 3:12 in my video that showed that brown rice consumption of two or extra servings per week was related to a decrease threat of diabetes, however presumably, the explanation it didn’t is as a result of consumption of white rice is related to an elevated threat of diabetes, and white rice represents 95 p.c of the U.S. rice trade. Switching out a 3rd of a serving of white rice a day for brown rice may decrease diabetes threat by 16 p.c, however switching out that very same white rice for entire grains basically, like oats or barley, may work even higher! So, different grains have about ten instances much less arsenic and are related to even decrease illness threat. No surprise the rice trade doesn’t cite this examine.
It does cite the Adventist research, although, and a few in vitro knowledge. For instance, in a petri dish, as you possibly can see at 4:05 in my video, there are rice phytonutrients that, at larger and larger doses, can inhibit the expansion of colon most cancers cells whereas apparently leaving regular colon cells alone, which is thrilling. And, certainly, those that occurred to eat these phytonutrients within the type of brown rice at least one time per week between colonoscopies had a 40 p.c decrease threat of creating polyps. (The consumption of inexperienced leafy greens, dried fruit, and beans have been additionally related to decrease polyp incidence.) However, the one cause we care in regards to the improvement of polyps is that polyps can flip into most cancers. However, there had by no means been research on brown rice consumption and most cancers…till now, which I focus on in my video Do the Pros of Brown Rice Outweigh the Cons of Arsenic?.
For these unfamiliar with my visitors gentle system, I speak about it in my guide trailer. Take a look at How Not to Die: An Animated Summary.
