This is a tough combination of health conditions for diet and the best approach would be for the patient to see an RD with experience working in diabates and kidney disease.
For blood sugar control the focus would be managing carbohydrate.
For CHF the focus would be on low sodium.
For CAD, fiber and healthy fats would be a focus.
For kidney disease, there may or may not be restrictions on protein, sodium, fluids, phosphorus, depending on the recommendation from the kidney specialist.
Diet for this patient needs to be individualized and an RD can help translate the recommendations appropriate into a workable meal plan to make it easier.
