You can usually eat spicy bars occasionally in small amounts after the new crown vaccine, but try to avoid them as long as you can control them or wait for a period of time when the vaccine immunization effect is relatively stable. The reason why eating too many spicy bars is not recommended is that they are a relatively greasy, spicy food and contain a high level of additives. The following negative effects may occur when consumed in large quantities after vaccination: 1. Aggravating adverse reactions: Due to the inherent characteristics of the vaccine itself, it can have a stimulating effect on the body’s immune system after vaccination. Therefore, after vaccination, some people may have adverse reactions in the gastrointestinal tract, such as nausea, abdominal pain, diarrhea, etc. The consumption of large amounts of spicy strips can cause significant stimulation and additional burden to the gastrointestinal tract, which may aggravate the discomfort of vaccinated patients. 2. Confusing adverse reactions: The gastrointestinal adverse reactions caused by New Crown vaccine are similar to those caused by eating too many spicy strips, which can cause abdominal pain, diarrhea and other gastrointestinal symptoms. Therefore, adverse reactions caused by the vaccination may be mistakenly thought to be caused by eating too many spicy strips. In the case of more severe adverse reactions, the condition may be delayed. It is recommended to eat a light diet, take appropriate supplements of fresh fruits and vegetables, and avoid spicy and irritating foods or alcohol to prevent aggravating the adverse reactions or affecting the effect of the vaccine.
