In the series ASK DOCTA! "Medicine made simple" by Dr. med. Emmanuel Anyangwe Ngassa this time the focus is again on chronic kidney disease and it's about nutrition as regards to dialysis patients. Ms Bernadette Keyi, a trained nephrology nurse working in the USA, originally from Cameroon, discusses with Ask Docta! about the types of foodstuff that dialysis patients especially in Cameroon and Africa should or should not eat.
