Basically, lotus seeds have no taboos. You can eat them with any food. Lotus seeds can calm the mind, relieve troubles, and replenish qi and blood. Lotus seeds can be combined with red dates, lilies, pig hearts, white fungus, rice, and beans. The effect is better when eaten together.
Medical book explanation: Pork belly and lotus seeds, when boiled with white eggplant branches to make a fire, become highly poisonous and will cause death if eaten. I don't think it's necessarily true. Who will eat pork belly and lotus seeds? It definitely doesn't taste right.
