Harold B. Lee said this quote

There are promises of protection in the Word of Wisdom. The Lord’s word of wisdom commanding abstinence from a worldly “king’s portion” of tobacco, tea and coffee, and alcoholic beverages that are habit-forming, and which counsels the simple diet of fruits, grains, and vegetables in season, with meats used sparingly, has been given you as a revelation of God’s great law of health. It stands today as a challenge to a world surfeited with things condemned as unclean and unfit for the human body.If you have faith as the youthful Daniel and his brethren and purpose in your hearts that you will not defile yourselves with “king’s meat and wine,” even though you may be two thousand miles east of the Suez Canal, your faith will have the reward of hidden treasures of knowledge, of strong bodies that can “run and not be weary and walk and not faint.” If by faith in this great law, you refrain from the use of food and drink harmful to your bodies, you will not become a ready prey to scourges that shall sweep the land, as in the days of the people of Moses in Egypt, bringing death to every household that has not heeded the commandments of God.
