It is incorrect to say that soy sauce is not a stimulating food and usually has no significant effect on the recovery of wounds. There is no scientific basis for the rumor that eating soy sauce can cause hyperpigmentation of wounds, so you should not listen to it at will, but it is recommended to eat soy sauce in moderation and avoid too much on a daily basis. Soy sauce is mainly made from fermented soybeans. During the fermentation process, tyrosine is oxidized and amylase hydrolyzes starch to produce glucose and amino acids, which in turn produces melanin-like pigments, making soy sauce reddish-brown and blackish. Because soy sauce is a condiment and is consumed in small amounts on a daily basis, eating soy sauce will not enter the skin cells with the blood and thus have an adverse effect on the wound, and most of it will be excreted in the feces. The local damage to the wound is mainly caused by the lack of attention to personal hygiene or the consumption of irritating food during the recovery period, resulting in infection of the wound, as well as the lack of attention to sun protection and local pigmentation. Thus, it is possible to eat soy sauce with wounds, but it is not recommended to eat too much, because soy sauce is rich in salt, and excessive consumption of soy sauce can easily make the daily intake of salt exceed the limit, which is not conducive to health. In addition, for patients with wounds, disinfection should be carried out in a timely manner, and active medical debridement is required for larger wounds, followed by regular medication changes as prescribed by the doctor. Avoid spicy and irritating diet, such as chili, onion, alcohol, etc., and pay attention to no local water, so as to avoid secondary infection, which is not conducive to the recovery of the wound. At the same time, during the recovery period, local sun protection, scratching the wound is strictly prohibited to help the wound healing and reduce the possibility of hyperpigmentation.
