In fact, Western medicine does not say this. It is actually a traditional Chinese medicine saying that spicy and hot foods should not be eaten after surgery.
Because you have wounds after surgery, you are more susceptible to infection.
Traditional Chinese medicine believes that beef is warm in nature and eating too much will cause internal heat, which is what Western medicine calls inflammation.
According to Chinese medicine’s understanding of medicinal materials, beef tendons and beef marrow are warm foods like beef, so it is best not to eat them, and if you eat them, don’t eat too much.
p.s. Beef tendons and beef marrow, you shouldn’t be eating hot pot, right? You may be able to eat some beef, but you must not eat hot pot. The hot pot is far more hot than beef and mutton. Just bear with it for a while. The most susceptible to infection is 48 hours after surgery. After 5 or 6 days, the wound will be almost healed, and the diet will no longer be so strict.
