Eat vegetables, fruits, things that are good for digestion and respiratory system, pears, kiwis and oranges. When you can eat, you must eat something containing vitamin C, honey water, honeysuckle and Ophiopogon japonicus.
Then there are sea cucumbers (if possible, one a day, it seems useless to eat Poseidon intermittently, especially in winter), bovine colostrum and other things that enhance immunity. You must prevent colds.
Also pay attention to keep the mouth and nasal cavity clean, rinse your mouth more, rinse your mouth with light salt water, and hold it if nothing happens. I feel much better than those hundreds of ointment recommended by the hospital.
Decisively refuse to eat salted fish, pickles, bacon, barbecue, bacon and other foods containing nitrosamines. Taboos such as not stimulating food, not drinking alcohol, etc. Just eat, and it is better to eat more.
Last time I watched TV, I said asparagus is the best anticancer drug.
