Damage to Food Quality and Nutrition
A 1999 study by Dr. Marc Lappe published in the Journal of Medicinal Food found that concentrations of beneficial phytoestrogen compounds thought to protect against heart disease and cancer were lower in genetically modified soybeans than in traditional strains. These and other studies, including Dr. Pusztai's, indicate that genetically engineering food will likely result in foods lower in quality and nutrition. For example the milk from cows injected with rBGH contains higher levels of pus, bacteria, and fat.
