Here's the question: "Do we know all the essential nutrients (for humans)
including the amounts required by humans for healthy nutrition?" What do you
think? What is the evidence? What is the difference between "essential
nutrients" and "RDI amounts of essential nutrients"? If you were a research
scientist how would you prove your hypothesis? We are not asking about
"foods" but rather "essential nutrients" - there's a difference!. We are not
talking about "therapeutic nutrition" but rather "normal nutrition"
"Science doesn't know everything" is not a good answer. "New foods will be
discovered" is not a good answer. Your answer should not include herbal
medications or drugs or answers like "who knows what we may discover in the
future?" or anything about possible discoveries in the Amazonian rain forest!
You may want to look up "Total Parenteral Nutrition" and see what is currently
being done in clinical nutrition based on current knowledge - does that help

Q3) List and describe the five principles of a healthy
diet.
Q4) Explain Dietary Reference Intakes (DRI) and
Recommended Dietary Allowances (RDA).
