Precautions for salmon:
1, Salmon, as a food rich in calcium, contains a lot of mineral elements, so it can't be eaten with some foods with high oxalic acid content, which may form calcium oxalate or magnesium oxalate, reducing its nutritional value, such as spinach, mustard, taro and so on.
2. Salmon is a kind of hot food, but it can't be eaten with some foods containing a lot of hot and dry gases, such as beef, mutton and crayfish. It may increase the dryness and heat, and produce some symptoms such as getting angry and sore throat.
It is best not to eat with fruit. Although there is no clear report, marine fish should try not to eat with fruits, because their ingredients and elements in fruits are mutually destructive.
