Anti-GMO groups draw FDA rebuke over misrepresentation of Golden Rice nutrition

Finally, the FDA weighed in on Golden Rice, with its May 24 announcement approving it for use in the United States. This approval, just a few months after Canada, Australia and New Zealand’s agencies issued theirs, is largely symbolic, since the International Rice Research Institute, now the makers of Golden Rice, have no intention of selling the product in the United States.

However, an FDA approval carries a lot of gravitas worldwide, and the decision is being met with attempts by anti-GM groups to discredit the nutritional value and usefulness of Golden Rice.

Just after the FDA’s approval, Independent Science News, a website known for its opposition to genetic engineering and recombinant technologies, published an article headlined “GMO Golden Rice Offers no Nutritional Benefits Says FDA.” Sustainable Pulse, another anti-GM organization reprinted the article, focusing on a misleading nutritional fact that both groups (among others) have perpetuated:

But, in a surprising twist, the US Food and Drug Administration (FDA) has concluded its consultation process on Golden Rice by informing its current developers, the International Rice Research Institute (IRRI), that Golden Rice does not meet the nutritional requirements to make a health claim.

This has been a common criticism of golden rice from groups like ISN and Greenpeace, which argue the approved version of Golden Rice doesn’t have enough beta-carotene, the precursor to Vitamin A, to make a nutritional difference. Instead, these groups advocate planting bananas, carrots, spinach or sweet potatoes, none of which are as affordable or even practical in places suffering from Vitamin A deficiency.

The article, written by ISN Executive Director Jonathan Latham and Assistant Editor Allison Wilson, pointed to a line in the FDA approval letter that observed that “the version of Golden Rice approved, called GR2E, contains very little of the key ingredient, beta-carotene. Worse, even the little that it does contain rapidly degrades during storage. For the reasons, FDA has told its developed…that no health claims may be based on it.”

The FDA did state that. Also, Health Canada wrote that “Replacement of all rice and rice products in Canada with GR2E rice would result in a very small 0.8-8% (34 µg-239 µg per day) increase in ß-carotene intake.” But a health claim is not the same thing as a nutrition statement. So the FDA and Health Canada statements don’t translate into “no nutritional value,” nor does it mean that, as Latham and Wilson wrote, “the tradeoff experienced by the Golden Rice project between beta-carotene production and yield in its various GMO rices has not been resolved.”

The FDA also has since rebutted Latham and Wilson’s article, saying the claim of “no value” is misleading. In the comments section of the ISN website, this response was posted from Marianna Naum, communications team lead from the FDA’s Office of Food and Veterinary Medicine:

It is unfortunate that the statement you reference in our letter responding to BNF 158 has been misconstrued to suggest that there would be no value of the pro-vitamin A in golden rice for its use in the countries where it is intended for distribution.

Our statement applies only to labeling considerations in the United States, in that golden rice contains insufficient pro-vitamin A to warrant differential labeling for nutrient content based on the low levels of rice consumption in the U.S. Requirements for nutrient content claims on labels in the United States take two factors into account, the amount of the nutrient needed as well as it’s concentration in the food and the typical or average level of that food consumed in the U.S. For the rice to be labeled in the United States with a claim containing provitamin A, our regulations stipulate that the food must contain 10-19 percent of the RDI or DRV for the substance per reference amount customarily consumed (essentially a measure of consumption).

Additionally, U.S. consumers eat rice at very low levels compared to consumers in the specific Asian countries with vitamin A deficiency for which golden rice was developed. IRRI reports that consumption of rice by children in Bangladesh is 12.5 g/kg body weight/day, compared to about 0.5 g/kg bw/d for U.S. consumers). Rice is the major staple in those countries and levels of rice consumption are many-fold higher than they are in the U.S. While a U.S Consumer would be unlikely to eat enough of the rice to achieve that value (10-19 % of the NDI or RDA), that does not mean that the level of consumption of golden rice in the targeted countries would be insufficient to accomplish the intended effect of supplementing their very low consumption of vitamin A-containing foods. Consuming rice containing the levels of pro-vitamin A in GR2E rice as a staple of the diet could have a significant public health impact in populations that suffer from vitamin A deficiency.

The FDA, Health Canada and even Australia and New Zealand were looking at overall safety, and applying nutritional claims to their own, healthy populations. The Vitamin A/beta-carotene deficiency targeted by Golden Rice do no exist in those nations. That’s why IRRI has no intention of introducing Golden Rice to these industrialized countries—it does want to introduce it to countries, especially in Asia, that are experiencing high levels of Vitamin A deficiency among children and infants, killing up to two million children every year and making hundreds of thousands of them go blind.

golden 6 9 18 3In a letter to Latham that was obtained by the Genetic Literacy Project, Golden Rice Humanitarian Board Executive Secretary Adrian Dubock pointed out that these “first world” agencies did not access the nutritional benefit of added beta-carotene in developing countries. That’s because no recommended daily allowances exist for developing countries. So, the FDA considers a “nutrition claim” to address any food that has more than 10 percent of the daily RDA in a 45 gram serving. And golden rice doesn’t have that much carotene, but, as Dubock points out, it has enough:

Nutritionists calculate that 30-40% of the EAR (estimated average requirement) for a source of Vitamin A, consumed daily is sufficient to prevent the two separate morbidities of Vitamin A deficiency, blindness and the loss of a functional immune system,” Dubock wrote. “Only a few tens of grams of dry Golden Rice, when cooked and consumed daily, is expected to combat vitamin A deficiency and save life and site.

In countries throughout Asia that consume up to 300 grams of rice every day, this means a lot more beta-carotene could be consumed than in the United States, where even 45 grams might be a high figure. Rice is a much cheaper stape, and also much more affordable than meat and other animal products, and colored fruits and vegetables like bananas and carrots (the latter which was bred to enhance beta-carotene content, incidentally, in the 14th century).

Latham and Wilson’s article states that:

In an attached memo, FDA notes the beta-carotene content of unmilled Golden Rice GR2E ranged from 0.50-2.35 ug/g. That is, beta-carotene levels in Golden Rice are both low and variable. This compares to beta-carotene levels measured in non-GMO foods such as fresh carrot (13.8-49.3 ug/g); Asian greens (19.74-66.04 ug/g); and spinach (111 ug/g).

But, as Michigan State University plant biologist Chad Niederhuth wrote in a response to the article, these are comparing apples and oranges:

It is obvious in the FDA letter than beta carotene levels are considerably higher than that of normal rice. The FDA letter states that beta carotene in the non-Golden Rice controls was below the limit of quantification of 0.07 mg/kg, in Golden Rice it was 0.504 to 2.35 mg/kg…many times higher. Wilson and Latham never actually tell you how much higher Golden Rice’s beta carotene levels compared to equivalent consumed rice varieties. Instead they compare it to older versions of Golden Rrice or other crops like carrots.

Carrots, spinach and sweet potatoes can’t be easily or cheaply grown in southeast Asia.

  1. I just left the statement from Health Canada in a comment on that article because they essentially accused Canada of being part of a conspiracy to, in the words of Jonathan Latham in a comment: “I think also it is clear that these approvals (Canada, Australia/New Zealand; USA), which IRRI is now boasting about on its website, are really to pressure the Philippines and Bangladesh to approve GMO Golden Rice.” Here is the statement from Health Canada that, unlike the FDA, does not figure nutritional value of GR2E in terms of Canadian consumption:
    Following this assessment, it was determined that the changes made in this rice variety did not pose a greater risk to human health than rice varieties currently available on the Canadian market. In addition, Health Canada also concluded that GR2E would have no impact on allergies, and that there were no differences in the nutritional value of GR2E compared to other traditional rice varieties available for consumption except for increased levels of provitamin A.
    Let’s see if Wilson and Latham have the guts to post it.

        • Playing the shill gambit is always a forfeit of the debate at hand. It is a shitty form of cheating by trying to poison the well rather than countering with a cogent refutation that might prove your point or win a debate. I see lameoids pull this stupid blunder 10 times a day in the GMO debate. If you want to prove a fault in science, use the tools scientists use, peer reviewed studies and unbiased information sources. If you don’t have solid evidence, consider what a fool you are being. Shill shill shill just makes you look like a blathering idiot and forfeits every time, the win goes to science truth. Explained simply here: https://en.wikipedia.org/wiki/Poisoning_the_well This is especially ludicrous when you consider the GMO safety debate ended two full years ago and no company for profit anywhere would spend a single penny paying a “shill” to promote something already attained.

      • Hey, they’ve got to make room for the new inventory. Transgenics are so 2015; get with the times, 2018 is all about:

        Cisgenics! We don’t know why it’s bad, but corporations like it so it must be!

    • Amazing. A non-profit like IRRI is able to buy the FDA, Health Canada and the Australian and New Zealand regulatory agencies. Not to mention all the scientists, including Nobel laureates, that concur with the safety of this rice. It’s almost like they also have to own all the banks to create that bribe money out of thin air.
      There is a point where a conspiracy theory goes beyond ridiculous and becomes farce. You have passed that point.

        • I hear that back from pro-disease cheerleaders, flat earthers, young earth creationists and all sorts of science deniers. You know, the ones in the full sensory deprivation echo chambers.

          • Oh, dear. A shill accusation. Straight off of the cheat sheet for how to lose an argument automatically.
            I would tell my handler, but since I am the only one who has that job, I try to avoid talking to myself more than necessary. I try to save it for muttering under my breath about the low level of intellectual capacity of some responders.

          • If you are so bright how about offering some actual evidence instead of just making dumb comments about blinders and shills.

          • Well for starters I stand on my own two feet I do not have a bunch of industry..or in my case anti-everything…shills come to defend me I speak my peace & call a spade a spade. I actually have a weekly production about agriculture news.
            Yesterday it was discovered…another crock as this has been spoken about for 10 years now…that GMO wheat has been illegally grown in Canada . a strain that was not supposed to be in production except in controlled environment testing areas & not grown since 2004…but you and the other deceptive gutless pathetic poltroons that cannot think for themselves wish to claim has been a conspiracy theory…as you do here.
            It is only the MPM that gang up in folks in social media nit the ones speaking truth and talking common sense.
            You & cohorts play some sort of intellect in social media. The reality is your a sad lot

          • Yet you still fail to present any evidence of any harm and you certainly didn’t present a shred of evidence of any problem with golden rice. You just yammer on about shills.

          • I present evidence in my podcasts with links…unlike you idiot shills i actually present a case. In addition when it comes to golden rice a 14 year old embarrased an industry shill on how pathetic your side of of the isle is with the propaganda and lies. America is not the target of need so why are we growing it? Why are the countries that need this remedy refusing it?
            You want evidence stop being lazy the truth is there unless as in your case you’re too brainwashed to see it

    • Cliche and intellectually lazy comment. Not saying FDA bats 1000%, but as this article demonstrates, substituting Latham’s wisdom gets us much further from the truth. I’ll trust FDA on its worst day over Latham any day.

  2. I love how they want to argue that there’s no health benefits and think they can also scaremonger on the harm.

    They always have it both ways–anti-GMO folks are so delightfully flexible with their misinformation!

  3. Wow, the mendacity of the anti-GMO crowd is just beyond belief. They have been waging a war on Golden Rice from the get-go because it doesn’t fit their pesticide-soaked-frankenfood narrative. I frankly would love to eat Golden Rice. Maybe the IRRI should sell it here as a fund-raiser? If you don’t like rice, you can at least throw it at the Antis. Hmmm, lets see, if I get normal rice and soak it in turmeric water for a while…
