The China Study: The Most Comprehensive Study of Nutrition Ever Conducted and the Startling Implications for Diet, Weight Loss and Long-Term Health

by T. Colin Campbell

In the China Study, we assessed antioxidant status by recording the intakes of vitamin C and beta-carotene and measuring the blood levels of vitamin C, vitamin E and carotenoids. Among these antioxidant bio-markers, vitamin C provided the most impressive evidence. The most significant vitamin C association with cancer was its relationship with the number of cancer-prone families in each area.42 When levels of vitamin C in the blood were low, these families were more likely to have a high incidence of cancer.III Low vitamin C was prominently associated with higher risk for esophageal cancer,III for leukemia and cancers of the nasopharynx, breast, stomach, liver, rectum, colon and lung.
