ANTICANCER AGENTS OF DIETARY ORIGIN VERSUS THOSE OF PHARMACEUTICAL ORIGIN
Molecules naturally occurring in food
• Known chemical structures
• Well-defined cellular and molecular targets
• Natural
• Selected over the course of evolution
• No side effects
• Synergy or antagonism selected over the course of evolution
Pharmaceutically derived molecules
• Known chemical structures
• Well-defined cellular and molecular targets
• Synthetic
• Selected in the laboratory
• Sometimes very pronounced side effects
• Synergy or antagonism rarely observed, due to chance
