Back in the day of my graduate years, the main topic for my dissertation research project was to investigate what if any differences occurred in breast cancer rates in female rats when given diets containing either omega-3 or omega-6 fatty acids. Spoiler: we found no significant differences in breast tumor incidence between our four groups of rats. So we repeated the study and still found no difference. Needless to say, it was a disappointment since every graduate student is sure they will inadvertently discover the cure for some disease and of course cancer was the big prize. No Nobel Prize here in other words.
Since then, diet and cancer research has progressed from dietary fats to the idea that diet and cancer associations involved the newly discovered phytochemicals found in fruits and vegetables that have the potential for cancer prevention. The study found HERE was observational (no cause and effect). However the study was huge and lasted for 32 years.
Some fear has been generated that conventional produce is not safe to eat due to the presence of harmful pesticides. It is important to know that all produce may have some pesticide residues and that organic crops may use less or less toxic pest control methods. Bottom Line: Enjoy eating more of any kind of produce – conventional or organic. Both have very similar nutritive values and health benefits. It’s your personal choice but we need to know the facts and not avoid fruits and vegetables due to pesticide fears.
