Scripture commands "whether you eat or drink, or whatever you do, do it all for the glory of God" 1 Cor 10:31 (NIV). With this counsel as a cornerstone, the author offers inspired advice on an often neglected factor in religion: how to eat for optimum health. The compilers have included almost everything Ellen White wrote on such topics as the relationship of diet to spirituality, vegetarianism, fasting, digestion, overeating, institutional menus, and how best to teach the principles of health to others. Strong counsel against intemperance in the use of fat, sugar, and condiments is balanced with counsel against extremes in diet. Ellen White's writings in the field of health have stood well against the test of time and the advances of science. Generations of readers have found them to be a powerful aid in attaining that self control that promotes clearness of mind and purity of heart.
