Persimmon cakes are cold, so pregnant women had better eat less. Of course, persimmon cakes and sugar cane are not in conflict with each other, and they will not be poisoned if eaten. If pregnant women are in good health, it should not be too much problem to eat less in moderation. But even if you are not pregnant, if your stomach is weak, you'd better not eat too many persimmon cakes on an empty stomach, which will cause certain irritation to your stomach. In addition, don't eat persimmon with other cold things, such as crab meat, which may easily cause symptoms such as diarrhea and abdominal pain.
