As someone with Congestive Heart Failure (CHF) and living on Molokai, one of Hawaii's outer islands, I am intimately familiar with dietary requirements.  I'm prepared to deal with celiac, diabetes, renal failure, low salt, low fat and other medically required diets.  I am aware of religious requirements but am not yet ready to cope with full on Kosher or Halal requirements.  I am more than happy to help with vegetarian and vegan meals and prefer the local organic produce.
