If you have a cold and are in the initial stage of the illness, it is best not to eat beef. However, during the recovery phase, it is appropriate to consume some beef. As beef is a warming and nourishing food rich in protein, trace elements, and other nutrients, it can fulfill the body's various nutritional needs. Eating beef can enhance one’s resistance and aid in quicker recovery from the illness. It is also recommended to eat beef in moderation and not consume too much at once, as excessive intake can lead to gastrointestinal discomfort and potentially burden the digestive system, causing symptoms of indigestion. It is advisable to drink appropriate amounts of water to boost metabolism and improve resistance. Additionally, during a cold, it is important to rest adequately, avoid overexertion, and maintain a light diet.
