Here I am saying eat lots of fruits and veggies to prevent cancer, but you may have heard about this study published last Summer. Took women diagnosed with breast cancer asked them to eat a diet very high fruit and veggie diet to see if they’d live longer, and… they did not live any longer, leading to headlines like this: “Diet high in fruits and veggies no particular benefit” “Extra servings of fruits and veggies fail.” And you can always count on the British tabloids: “Cancer fruit flop,” and “veggies blow!”

Before you empty out your crisper Just what exactly did they mean by very high consumption. At baseline, before the study began, these women were eating 3.5 servings of fruit a day. Then, after three years of nutritional counseling, cooking classes and newsletters meant to boost fruit and veggie consumption, they started at 3.5 and ended up at the “very high” intake of… 3.4. Fruit consumption went down. No wonder they didn’t live any longer.

Now they did eat a few more veggies, but combined, after 3 years, their fruit and vegetable consumption went up 1.8 servings. That, ladies and gentlemen, is their idea of a diet “very high” in fruits and veggies. What a joke.

    Dr. Greger,

    What do you think of this research on antioxidents? They do mention vitamins are not good, as you say. But to eat blueberries only because they taste good?
