It's too late to dismiss GMO, because there will not be enough food for us all to eat. GMO is being tested again and again.
It's also mentioned in the article itself
The good news is that the reason wheat has become so toxic in the United States is not because it is secretly GMO as I had feared (thank goodness!).
The bad news is that the problem lies with the manner in which wheat is grown and harvested by conventional wheat farmers.
Then again, i don't like these kind of websites. They are usually very single minded and there's no scientific papers or proof to their claims.
