Here is what I think many here at Curezone will consider a fun challenge/activity! Compose what you consider to be the optimal ideal diet for one day -- the healthiest possible things you could ingest! Disregard your personal taste, cost, and how you could actually work various items into reasonable dishes.
Let's say you are assigned to develop an optimal nutrition plan for a human to eat every day for a year, as a test. Yes, variety is important, but pretend this person must eat the exact same things every day.
Just list all the food (as well as herbs/supplements) that you wish to include.
