(NaturalNews) Presidential frontrunner Donald Trump continues to lead in most of the polls, with his popularity soaring as the candidate speaks controversial truths that his running mates wouldn't dare vocalize.

So far, Trump has distanced himself from large corporate donors in an attempt to prove that he has no controllers, voiced his concerns about the link between the autism epidemic and the administering of too many vaccines at once, and now, for a brief moment, he's seemingly taken on the world's most evil corporation: biotech seed giant Monsanto.

Yesterday, Trump's Twitter account, @realDonaldTrump, retweeted a post alleging that Iowans have had way too much 'Monsanto corn' that was 'creating issues in their brain'. The tweet, which was promptly deleted, was retweeted by Trump's account after reports broke of a new Iowa poll showing presidential candidate Ben Carson had taken the lead among Iowa caucus-goers.

"Retired neurosurgeon Ben Carson just achieved a milestone in the Republican presidential primary: edging front-runner Donald Trump in a notable poll," reported Business Insider.

"Quinnipiac University released a new Iowa survey on Thursday that found Carson leading Trump 28% to 20% among likely caucus-goers.

"Trump has led almost every national and state-based poll since he surged to the top of the crowded field over the summer, and he has continued to hold decisive leads in several new polls out this week.

"But Carson has been nipping at his heels," Business Insider reported.

Trump blames intern for tweeting about negative effects of Monsanto's GMO corn

Food activist and blogger Vani Hari, also known as the Food Babe, didn't miss a beat when she discovered Trump's diss to Monsanto, promptly reposting it on Facebook with the following caption:

"Calling all Presidential candidates to comment. Did Donald Trump just come out against #Monsanto?"



She later added an update to her post informing her followers that Trump had deleted his tweet.
Trump later posted on his account that the tweet bashing Monsanto, and Iowans, was a mistake, blaming it on a "young intern."



It's a shame that Trump deleted his Monsanto tweet; while he may have lost the endorsement of the biotech industry, he likely would have gained support from a plethora of voters who absolutely despise Monsanto and its controversial cancer-causing crops.

WHO finds glyphosate is "probably carcinogenic"

In March, the International Agency for Research on Cancer (IARC), a research division of the World Health Organization, announced that glyphosate, the primary ingredient in Monsanto's Roundup, which is the world's most commonly used herbicide, is "probably carcinogenic."

The announcement drew criticism from the biotech industry, namely Monsanto, which accused IARC scientists of "cherry picking" data. Subsequently, Monsanto tried to pressure the researchers into retracting their study.

They did no such thing. Instead, the study has gone viral, making headlines across the globe and even prompting some countries to remove glyphosate-containing products from store shelves.

"The Swiss company Coop said on Thursday that glyphosate-containing herbicides are no longer sold as a precaution: 'Even if the Federal Office for Agriculture (BLW) judge glyphosate can be continued without a health hazard for the population, the retailer decided on Monday 18th May not to sell any glyphosate product in the Coop supermarkets and Coop Building & Hobby hardware stores,'" reported FreshPlaza.com.

"In Germany there were relevant changes. Mid-May REWE Group announced an intention to remove glyphosate from their hardware store assortment. 'The 350 DIY stores of the REWE Group will make sure that all glyphosate products are removed by 30 September 2015,' stated REWE. 'As of today (11:05) the markets have no chance to reorder such products.'"
