Are gluten free diets in violation of the word of wisdom? Aside from celiacs and others with medical disorders which prevent them from eating certain grains, is there an official LDS church stance in relation to people who optionally choose to live a gluten free lifestyle, based on these verses in the word of wisdom:


  14 All grain is ordained for the use of man and of beasts, to be the staff of life, [...]
  
  16 All grain is good for the food of man; as also the fruit of the vine; that which yieldeth fruit, whether in the ground or above the ground—
  
  17 Nevertheless, wheat for man, and corn for the ox, and oats for the horse, and rye for the fowls and for swine, and for all beasts of the field, and barley for all useful animals, and for mild drinks, as also other grain. (D&amp;C 89:14,16-17)
There is no doctrinal condemnation for gluten free diets.  The Lord expects us to make judgement calls based on what we are given in many instances.  Someone living glueten free will not be kept from the temple. 

In Doctrine and Covenants 58, verse 26 the Lord said:


  For behold, it is not meet that I should command in all things; for he that is compelled in all things, the same is a slothful and not a wise servant; wherefore he receiveth no reward.


A lot of things are not black and white. 

In Preach My Gospel, Chapter 4, the missionary handbook, this is the "black and white" of the Word of Wisdom


  Remember that our bodies are sacred. We should treat them with respect and reverence. The Word of Wisdom teaches that we are to eat healthy foods. It teaches very specifically that we are to avoid harmful substances, including alcohol, tobacco, tea, and coffee. We must also avoid harmful drugs in any form.


I believe the answer to this question is personal and between the individual and God.
