Sore Throat: What Fruits Should Not Be Eaten
Generally speaking, when experiencing a sore throat, one should avoid eating fruits such as mangoes, durians, lychees, pineapples, and longans. Detailed explanations are as follows:

1. Mango
Mango is a heaty fruit, and consumption may increase internal body heat. Sore throats may be caused by inflammation, such as pharyngitis or tonsillitis; heaty fruits may intensify inflammatory responses in the body, worsening symptoms such as throat pain and swelling. Additionally, mangoes contain certain allergenic substances. People with sore throats and weakened immunity may face an increased risk of allergic reactions after consuming mangoes.
2. Durian
Durian is also a heaty fruit, with high calorie and sugar content. High-sugar foods may promote bacterial growth, potentially creating a more favorable environment for bacteria when the throat is already inflamed, thus hindering recovery.
3. Lychee
Lychee has a sweet and sour taste and a warm nature. Its warming properties may intensify internal heat in individuals with sore throats. Furthermore, lychees contain high levels of sugar; excessive sugar intake can increase the osmotic pressure in the mouth and throat, causing dehydration of the local mucous membranes and further aggravating throat discomfort. When the throat is sore, the mucous membrane is already in a sensitive and fragile state, and eating lychees might cause additional irritation.
4. Pineapple
Pineapples contain bromelain, an enzyme that breaks down proteins. Normally, moderate amounts of bromelain aid digestion. However, when experiencing a sore throat, bromelain may irritate already damaged throat mucosa, worsening pain and potentially causing allergic reactions.
5. Longan
Longan has a warm nature and may easily promote internal heat. Eating longan when experiencing a sore throat may worsen throat inflammation. Longan also contains high levels of sugar, which may remain in the mouth after consumption, promoting bacterial growth. This may delay recovery, and could also trigger other symptoms such as coughing.
During treatment for a sore throat, in addition to avoiding irritating foods, it is important to get sufficient rest, drink plenty of water, and use a humidifier to maintain moist indoor air, which also helps alleviate symptoms.
