Dealing with Uncertainty
• A safe guide to each and all is this: If in doubt as to any food or drink, whether it is good or harmful, let it alone until you have learned the truth in regard to it.  If anything offered is habit-forming, we will be safe in concluding that it contains some ingredients that are harmful to the body and should be avoided.
