Monsanto's GM corn MON810 has damaged rat intestines, according to a new study stored at the NIH. Damaged intestines can lead to poor nutrient uptake, leading to a host of diseases and conditions, although the symptoms may be subtle. This GM corn contained delta toxins, the same emitted by Bacillus thuringiensis (Bt).
