Below are links to backup studies concerning the fruits listed in Foods to eat & avoid for triple negative breast cancer. This makes more applicable research available to those who want additional information about how various fruits influence triple negative (ER-/PR-/HER2-) risk, development, growth and prognosis.
Fruit consumption inhibits triple negative disease primarily through the actions of component polyphenols such as ellagic acid (found in blackberries and muscadine grapes), fisetin (apples, strawberries), quercetin (black currants, cranberries), resveratrol (bilberries, lingonberries), rutin (blackberries, raspberries) and ursolic acid (apples, cherries), as well as melatonin (cherries).
Fruit micronutrients should be obtained by consuming them in 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 when the same compound is administered at high doses, it is more likely to have pharmacological effects, with possible unwanted outcomes. For example, resveratrol supplementation has been shown to promote mammary tumor growth and metastasis in mouse models of ER- breast cancer.
