GW 241
(Gospel Workers 1915 241)
Another cause of ill-health and of inefficiency in labor, is indigestion. It is impossible for the brain to do its best work when the digestive powers are abused. Many eat hurriedly of various kinds of food, which set up a war in the stomach, and thus confuse the brain. The use of unhealthful food, and overeating of even that which is wholesome, should alike be avoided. (GW 241.1) MC VC
Many eat at all hours, regardless of the laws of health. Then gloom covers the mind. How can men be honored with divine enlightenment, when they are so reckless in their habits, so inattentive to the light which God has given in regard to these things? (GW 241.2) MC VC
Brethren, is it not time for you to be converted on these points of selfish indulgence? “Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain corruptible crown; but we an incorruptible. I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: but I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway. 1 Corinthians 9:24-27. (GW 241.3) MC VC
Insufficient Diet VC
Do not, however, feel it your duty to live on an insufficient diet. Learn for yourselves what you should eat, what kinds of food best nourish the body, and then follow the dictates of reason and conscience. At meal-time cast off care and taxing thought. Do not be hurried, but eat slowly and with cheerfulness, your heart filled with gratitude to God for all His blessings. And do not engage in brain labor immediately after a meal. Exercise moderately, and give a little time for the stomach to begin its work. (GW 241.4) MC VC
