The current webpage is designed to make additional research available concerning how certain fruits or their major bioactive components can increase the treatment effects of aromatase inhibitors. At the bottom of this webpage are links to studies relating to the beneficial fruits in Foods to eat & avoid during aromatase inhibitor treatment.
The following fruits, their juice and extracts have been tested and found specifically to increase the inhibition of aromatase:
Fruit inhibits aromatase primarily through the actions of polyphenols, among them:
- Beta-carotene (apricots, cantaloupe, mangoes)
- Chrysin (passion fruit)
- Ellagic acid (blackberries, muscadine grapes, pomegranates & pomegranate juice)
- Lycopene (watermelon)
- Quercetin (black currants, cranberries & lingonberries, raspberries)
- Resveratrol (blueberries & bilberries, red grapes, red currants)
as well as melatonin (cherries, especially sour or tart).
Fruit micronutrients should be obtained by eating fruit rather than taking supplements. When a beneficial micronutrient is administered at low doses by consuming food, it is likely to have subtle chemopreventive effects, whereas the same compound administered at high doses is more likely to have pharmacological effects, with possible unwanted outcomes. For example, resveratrol has been reported to promote proliferation of ER+/PR+ cells under some circumstances. In fact, while resveratrol has been shown to reduce ER+ cell growth at the earlier stages of cancer development, it can promote ER+ proliferation during later stages.
