Give them a try Mazzy and let us know! It's potassium that is lacking which causes my problems.
"Good sources of potassium include: potatoes, sweet potatoes, bananas, tomato sauce (without added salt or sugar), orange juice, tuna (fresh, frozen or tinned, but avoid tuna packed in brine), yoghurt and fat-free milk.
"If you have kidney disease, or are taking certain blood pressure medications, a large increase in potassium could be harmful. In this case, avoid taking potassium supplements and check with your doctor before dramatically increasing your potassium intake.

I eat a varied diet. DH cooks with lots of tomatoes, ginger, garlic - the base for most of our evening meals. I don't like tomatoes per se. Haven't eaten as many bananas in recent months. Don't like fish much

…… nor oranges ……… and can never see the point of 'fat free' milk !
