But, on the other hand, the idea that women, because of their special condition, may let the appetite run riot, is a mistake based on custom, but not on sound sense. The appetite of women in this condition may be variable, fitful, and difficult to gratify; and custom allows her to have anything she may fancy, without consulting reason as to whether such food can supply nutrition for her body and for the growth of her child. The food should be nutritious, but should not be of an exciting quality. Custom says that if she wants flesh meats, pickles, spiced food, or mince pies, let her have them; appetite alone is to be consulted. This is a great mistake, and does much harm. The harm cannot be estimated. If ever there is need of simplicity of diet and special care as to the quality of food eaten, it is in this important period. CH 77.1
Women who possess principle and who are well instructed will not depart from simplicity of diet at this time of all others. They will consider that another life is dependent upon them and will be careful in all their habits, and especially in diet. They should not eat that which is innutritious and exciting, simply because it tastes good. There are too many counselors ready to persuade them to do things which reason would tell them they ought not to do. CH 78.1
Diseased children are born because of the gratification of appetite by the parents. The system did not demand the variety of food upon which the mind dwelt. Because once in the mind it must be in the stomach, is a great error, which Christian women should reject. Imagination should not be allowed to control the wants of the system. Those who allow the taste to rule, will suffer the penalty of transgressing the laws of their being. And the matter does not end here; their innocent offspring also will be sufferers.... CH 78.2
