Oleic acid and er positive status -a bit confused

The concern over flaxseeds and ER/PR is that they contain phytoestrogens and also that ER/PR patients tend to be on anti-estrogen medications and the interactions between these and flaxseeds haven't been worked out. For these reasons, some people think that flaxseeds require further study in ER/PR+ patients.

Fortunately, there are many other sources of oleic acid.
