Thank you for your response. I guess I am confused because when I researched the blood pressure medicine, lisinopril (an ACE inhibitor), which he takes, the research says that this medicine can increase one’s potassium level. So, I thought that if one reduces the dosage of this medicine, then the potassium level would also be reduced. And, if his potassium is lower, he can eat the foods listed under the high-potassium category, as those are the foods he enjoys. The DASH diet sounds good since it includes fruits & vegetables, which he would like to eat, but many of them are high in potassium and his goal is to reduce his potassium level. He has been sticking to the lower potassium foods which makes his food choices very limited. See the dilemma here? Can you offer any additional suggestions? Thanks so much!
