A Clip from The China Study by T. Colin Campbell
‘..A pattern was beginning to emerge: nutrients from animal-based foods increased tumor development while nutrients from plant-based foods decreased tumor development. In our large lifetime study of rats with tumors, the pattern was consistent. In mice with hepatitis B virus-altered genes, the pattern was consistent. In studies done with breast cancer, the pattern was consistent. In studies of pancreatic cancer the pattern was consistent. In studies on cancer initiation the pattern was consistent. From the first stage of cancer initiation to the second stage of cancer promotion, the pattern was consistent. From one mechanism to another, the pattern was consistent.
So much consistency was stunningly impressive, but one aspect of this research demanded that we remain cautious: all this evidence was gathered in experimental animal studies. Although there are strong arguments that these provocative findings are qualitatively relevant to human health, we cannot know the quantitative relevance. We need direct evidence from human research. It was time to study the role of nutrition, lifestyle, and disease in the most comprehensive manner ever undertaken in the history of medicine…’
