More produce does not produce more cancer protection

No more bolting more blueberries which, when eaten in a hurry and underchewed, come out looking about like they did going down. Apparently the daily five as in five servings of fruits and veggies is good breast cancer prevention, but more is not better.

While my medical partner is a star when it comes to packing a little lunchbox full of baby carrots, cherries, grapes, etc., my produce produces mold and turns to slime in my crisper bin. I was pleased, therefore, to read the results from this study of 3,000 breast cancer survivors. One group followed the five per day formula while the other half were schooled in the more the merrier philosophy of vegan fare. There was no statistically significant difference in breast cancer recurrence between one group or another.

Lead author John Pierce of the University of California, San Diego concluded "You don't need to go overboard." He did note that daily exercise remains clearly associated with better outcomes in breast cancer survivors. And, as Susan Gapstur of Northwestern University adds, "At the end of the day, it's never wrong or bad to eat healthfully."
