Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, refuted the claim that tomatoes and crabs eat together as arsenic. After mixing the two, the determination result of inorganic arsenic is less than 0.06 mg/kg, far below the national standard, and this substance is already in crabs, but it has not increased at all after adding tomatoes.
Each ingredient has its own unique effect, but sometimes when inappropriate ingredients are eaten together, the effect may become an inducement, which is what we call food mutual grams.
Extended data:
There are also the following rumors about food cannibalism:
Spinach and tofu: Spinach and tofu are considered to be similar to each other by many people. The reason is that tofu contains calcium and spinach contains oxalic acid. Eating the two together will form calcium oxalate, which is easy to get stones.
In fact, this problem is very easy to solve. Blanching spinach in advance will reduce the oxalic acid content in spinach and reduce the generation of calcium oxalate, thus improving the utilization rate of calcium in tofu. Except spinach, such as rape, Chinese cabbage and amaranth with high oxalic acid content, it is recommended to blanch with clear water before eating to avoid the loss of minerals such as calcium in the body. ?
Cucumber and tomato: some people say that eating cucumber and tomato together will lose vitamin C, so they can't eat together! We know that cucumber contains vitamin C decomposing enzyme, which will destroy VC, but it will destroy its own vitamin C first, instead of looking for the vitamin C of tomatoes. It makes no sense that the two are mutually exclusive!
Potatoes and eggs: when I was a child, I heard adults say that eating potatoes and eggs together would be toxic. Someone believes it! In fact, there is no scientific reason. Potato omelet made of eggs and potatoes is nutritious, healthy and delicious, which not only has high-quality protein provided by eggs, but also has delicate starch, vitamins and dietary fiber provided by potatoes. Foreigners often mix these two ingredients to make potato and egg cheesecake, which is very delicious.
