While Ellen White did not explicitly forbid fish in all circumstances, her writings strongly advise against its consumption, particularly due to concerns about contamination and as part of her broader counsel against flesh foods.
She stated: "In many places fish become so contaminated by the filth on which they feed as to be a cause of disease. This is especially the case where the fish come in contact with the sewage of large cities. The fish that are fed on the contents of the drains may pass into distant waters and may be caught where the water is pure and fresh. Thus when used as food they bring disease and death on those who do not suspect the danger" (
MH 314.3).
More generally, Ellen White taught that animal food was not part of God's original diet for humanity: "The diet appointed man in the beginning did not include animal food. Not till after the Flood, when every green thing on the earth had been destroyed, did man receive permission to eat flesh" (MH 311). She further explained that after the Flood, God permitted animal food to "shorten their sinful lives" (
4aSG 121.2), and that "Since the flood the human race has been shortening the period of its existence. Physical, mental, and moral degeneracy is rapidly increasing in these last days" (Unpublished Testimonies, January 11, 1897, cited in
HL 98.4).
She emphasized that "Flesh foods are injurious to the physical well-being, and we should learn to do without them" (9T 156). She also noted that "It is a mistake to suppose that muscular strength depends on the use of animal food. The needs of the system can be better supplied, and more vigorous health can be enjoyed, without its use" (
MH 316.2).
Therefore, based on her principles, fish is generally not recommended as part of a healthful diet, primarily due to the risk of disease from contamination and the overall counsel against consuming flesh foods.
