Here I give two examples:
One is asked by Dr Alka Rani in the thread:

Another is "Why then do experimental animals not survive on diets lacking essential amino or fatty acids?", asked by Dr C.A. (Kees) Kan in the thread:
https://www.researchgate.net/post/Protein_fat_carbohydrate_are_interconvertible_in_the_body_Can_we_survive_on_zero_protein_Any_Scientific_experiments
These questions have helped me to understand the importance of microbiome to our health.
Do you have encountered any good questions in researchGate that inspires and enlightens you?
