Pres. Monson also counseled us by saying”…may we care for our bodies and our minds by observing the principles set forth in the Word of Wisdom, a divinely provided plan.”
Specific directions have been given to use about the foods we should eat and which substances to avoid.
When you are preparing for difficult situations consider planing your food storage around the principle of the Word of Wisdom.
This is a a great cook book to you help plan for your food storage: A World of Wisdom: Seasonal, Grain-based, Low Animal Product, Whole Foods Recipes
In addition to the above consider the following: We were also counseled by Quinton L. Cook during the Oct 2016 conference to avoid “Looking beyond the Mark”. He says that “Gospel extremism is when one elevates any gospel principle above other equally important principles and takes a position that is beyond or contrary to the teachings of Church leaders.”
Elder Cook in the same talk counsels “If we turn a health law (Word of Wisdom) or any other principle into a form of religious fanaticism, we are looking beyond the mark.” – a prime example: “expensive preparation for end-of-days scenarios”. So finding a balance between your temporal and spiritual preparations are important.
Hope this helps.
