Special characteristic of food 1

I was watching a series last night about traditional food and cooking. I was reminded of the special characteristic of foods that we prepare, the effects to those who eat them.

One ingredient has many elements.
If mixed with a certain thing it may bring out the best effect, but sometimes it may cause harm and cannot be mixed with certain ingredients. That is the special characteristic of food.

Just like for example, in order to remove the odor of the pork, clover flower bud is added, but if it is added to turmeric herbal soup, if will cause diarrhoea and vomiting.
