Hi - My Name Is Ann Hall. I Am 54

hi - my name is Ann Hall. I am 54 year old female. I have been taking for a long period of time HCTZ, to control blood pressure along with atenolol, and my primary care doctor said my potassium level is a little low to the diuretic I am taking, what foods would you suggest if I want to increase level with diet instead of a potassium supplement. Thank you.
