My special diet is killing me

Naturally, I don’t crave for foods that are high in sodium nitrates, salts and fats.
I am generally a fruit, veggie and fluid person but due to some problems in my kidney, I am retaining water and my low-density lipoproteins (LDL) has shot up about 200% the normal value.
As such, I have instructed to eat generally bland food.
Arrgh!
 I pray that this problem would just go away.
