JOEL - The Word of Wisdom(WofW) is more of a guideline for healthy living and for keeping our bodies clean like a temple(1 Cor. 6:19). We are told in Section 89 of the D&C that it is "not by commandment or constraint, but by revelation and the word of wisdom". (D&C 89:2)

So this scripture is not a commandment, even though some members can make a "big deal" about living this doctrine. But rather than worry so much about the details of what is OK and not OK we should at least conform to the spirit of the law in what we take into our bodies.
For active LDS members, especially those who wish to enter the temples, there are certain things we have been asked to not use; Alcohol, tobacco, coffee, and black tea. We demonstrate our obedience to God by refraining from taking these things.
But we have also been advised by our modern-day leaders to not eat or drink anything containing harmful drugs, in a way that would result in a habitual use of the drug (1972 letter from First Presidency).
So, if a person becomes addicted to Mountain Dew then he could be considered is breaking the WofW. If he is not addicted to it and drinks it only occaisionaly then perhaps he is not breaking the WofW.
A person who has a history of cardiovascular disease in the family could be considered breaking the WofW if he eats foods high in cholesterol. This doctrine can be followed according to what is best for any individual's own physiology.
Things have changed over time. Because man keeps inventing new ways to harm the body, we need to use our own common sense and look to current medical studies and our prophet's advise to keep us updated on what is good and not good for our health.
For example, nowhere in the Word of Wisdom does it say we should not take illegal drugs, but in the world we live in today illegal drugs would most deffinately be included as something to avoid.
The wording about eating meat sparingly only says that it is "pleasing unto me that they should not be used, only in times of winter, or of cold, or famine." (D&C 89:13) Not a commandment, but pleasing to God that we do this. Actually the original 1835 edition of the Book of Commandments (Precursor to "Doctrine and Covenants"), leaves out a very important comma in verse 13, causing it to read: "And it is pleasing unto me that they should not be used only in times of winter, or of cold, or famine." With the comma gone after the word "used" it now reads that eating of meats should not be restricted to times of winter or famine. No one knows who put the comma in there for subsequent editions, only that it was inserted by an editor who was preparing the text for a new printing. Researchers are unaware of any direction from Church authorities to make the change. Regardless of this, the previous verse does say we should eat meat "sparingly".
We should live all God's commandments, but God has also 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." (D&C 58: 26)
The Word of Wisdom is one of those things where(except for a few things) God has not specified every little thing we should or should not use. Much of it is left up to the individual.
Members will live this doctrine according to their own personal level of obedience and faithfulness which can vary widely from one person to the next. We demonstrate our obedience to God by at least refraining from the few things that are specified by our church leaders.

WENDY - If Jesus came back today would he be clean shaven with a suit and tie obeying LDS church standards?

JOEL - I don't know how He would be dressed or what He would look like, but I hope I will know Him when I see Him.

WENDY - If Jesus was a mormon missionary what's he doing walking on water, when he's not supposed to be at the beach or near water?

JOEL - Jesus was not a Mormon missionary. He is the God of this world and as such has power and control over everything, everywhere, including the land and the water and Satan. Mormon missionaries do not, therefore they are warned to avoid the water(D&C 61, Rev. 8:8-11).

WENDY - Why do mormons call Catholics idoloatrous for their statues when at the liberty jail in Missouri there's a huge statue of Joseph Smith and a statue of Brigham Young in Utah where he said "this is the place?"

JOEL - The difference between a idol and a statue is that one is worshipped as a god or a representation of a god and the other is just put up in honor of and as a reminder of the person or the ideal it represents.
Americans don't worship the statue of liberty; but it does stand as a symbol of freedom for those who see it. Such is the case with the Joseph Smith and Brigham Young statues. Like a portrait on a wall they merely serve as a reminder of the person's life and what they accomplished.
Idolatry can occur on many levels. Some may worship graven images that represent a God; others worship money or their posessions, others may worship other people. This can happen to anyone in any religion.
Even though the Catholics might look at a crucifix of Jesus as they worship, at least they are worshipping the right person. I assure you we do not worship Joseph Smith or Brigham Young or the Statue of Liberty.
