The Word of Wisdom is a part of the religious system of the LDS Church which declares that the care of the body is a sacred duty. Three objectives have been kept in mind in the preparation of this book. First, to make clear the meaning of the Word of Wisdom in terms of modern knowledge. Second, to show that the learning of the last century confirms the teachings of the Word of Wisdom. Third, to furnish some information for the guidance, through proper nutrition, of those who seek to retain, improve or recover their health.
