In nutrition and food safety theory, there is no such thing as "food is equivalent". So far, no cases and related reports of food poisoning caused by the fact that food has been combined in real life have been seen. The reason for the so-called "compatibility of food" in the society is that food contains a large amount of oxalic acid and tannic acid, which in combination with calcium affects the absorption of nutrients. In fact, most plant foods contain oxalic acid. Take "spinach and tofu" as an example. Although oxalic acid can combine with some calcium, its effect is small, and calcium that has not been combined can still be absorbed by the body. What''s more, spinach and tofu contain protein, multivitamins, minerals, dietary fiber, and other healthful phytochemicals. Therefore, certain uncertain factors will give up the entire food.

　　The second is that it is related to the chemical reaction between foods. Taking "shrimp and fruit as a gram" as an example, it is believed that pentavalent arsenic in shrimp and vitamin C in fruit react chemically, and arsenic trioxide (arsenic trioxide) can be generated to cause poisoning.

　　 my country''s food safety standards regulate the limited amount of arsenic in seafood. The arsenic poisoning dose is 50 mg. According to the conversion factor, even if the arsenic contained in the shrimp reaches the maximum limit and there is enough vitamin C conversion, it is equivalent to one person eating 40 kg of shrimp to reach the poisoning dose.

　　The 110-year-old professor Zheng Ji told you the truth:

　　China’s nutrition expert Professor Zheng Ji once dealt with the so-called “food” food,

Such as

　　green onion+honey

　　sweet potato+banana

　　mung bean+dog meat

　　pine flower egg+sugar

　　 peanuts +cucumbers

　　green beans + caramel

　　kelp + pig blood

　　 persimmons + crabs etc.

　　 experiments with mice, monkeys and dogs The study, in which 7 groups were tested by the investigator on humans, did not observe any abnormal reaction.

　　The Chinese Nutrition Society commissioned Lanzhou University to carry out so-called "Xiang" food trial experiments on 100 healthy people, including

　　Pork + Lily

　　Chicken+sesame< /p>

　　Beef + Potato

　　Potato + Tomato

　　Leek+Spinach, etc.

　　Continuous observation for one week without any abnormal reaction.

　　Many studies have further shown that the notion that "food is relative" is untenable.
