Is it poisonous to eat red dates, duck eggs, mung beans, white rice and rock sugar to cook porridge?

Will not be poisoned. These are all good things, and they are not toxic in themselves. And it doesn't produce toxins.

However, it is also possible to cook porridge with red dates, mung beans and white rice, and finally add rock sugar;

Duck eggs are also cooked in porridge, which seems to be a bit inconsistent. It is better not to put them. It's better to fry duck eggs as a dish or eat salted duck eggs.
