lisinopril actavis and potassium

I have been through medicin detox (triptans and headache pills) for 8 weeks and the doctor has now put me on Lisinopril. I have read online that it can be dangorous to eat a diet high in potassium with the Lisinopril because it inhibbits the kidneys in getting rid of potassium. Now Im worried because I eat a vegan low fat diet where I get most of my calories from bananas and also I eat lots of greens with potassium. Do you have any knowledge about this subject? http://www.ncbi.nlm.nih.gov/pubmed/22431578
