Sometimes eating food together is purely accidental. I believe everyone has heard that tofu and honey can cause deafness, but this is not the case. It can be said that it has a history of many years in China. It is recorded in Synopsis of the Golden Chamber that eating raw meat and drinking some dairy products may lead to white worms. For this statement, scientists have confirmed that it is false, because there is a kind of worm that is parasitic on pork and beef.
If it is not cooked, eggs will be eaten into our stomachs, producing parasites. This is not because of the food itself, but because the food is produced. Some people do have diarrhea when drinking beer while eating seafood, but this does not mean that the food is not clean enough, and some people eat too much, which will also cause this situation. For allergic people, it will cause skin discomfort, but it is definitely not food.
Food is a rumor, and some people deliberately use these rumors to make money. We will find such books on the Internet and in bookstores. If we look closely, we will find that these authors have no professional background, and these books are just crash books. So, don't believe any more rumors about what food to eat together. Believe in science. Eating some foods together will only cause physical discomfort.
