Elderly Care Providers Where Can I Find Recipes For VERY Special Diets For Elderly People?

Where can I find recipes for VERY special diets for elderly people? - elderly care providers

I am a provider of full-time service for an old man, and every time I saw him to the doctor, we found a new restriction on what they can eat. I'm at the end of my soul. I want a website or a cookbook (or spices, and some of his favorite recipes) foods disturb little sodium, starch / sugar, cholesterol and fat, nor taste enough for him, not the salt.
