All kinds of “fruit diseases”

The fruit is rich in nutrients and tastes good, and is very popular among people. However, from the perspective of medical nutrition, some fruits are not suitable for everyone, blindly eating more, and may suffer from “fruit diseases.”


Mango is known as the “tropical fruit king”. When some people eat mango, the skin of the lips, cheeks and ears will appear red and swollen, erythema, and quickly spread to the trunk and limbs of the body. Some of them have scattered needles and big herpes, accompanied by itching, and eczema after scratching. If you change, you may have fever, chills, and pain.

Treatment measures: stop eating mangoes and other fruits, especially fresh, freshly picked; topical anti-allergic drugs, corticosteroids can be widely used, the effect is particularly good, but can not be used for a long time, otherwise the side effects are large; avoid heat Wash water with soap and soap; avoid allergic foods.


Pineapple is known as the “banquet fruit” because it contains bromelain which helps to digest fish protein, especially for feasting. Although pineapples are delicious, there are many taboos. There are two substances in pineapple that can adversely affect the human body. Some people feel numbness in the mouth, irritated skin and cheeks, and even flustered headaches. This is because serotonin contained in pineapples causes allergic reactions and causes blood vessels to contract and blood pressure to rise. Therefore, people with cardiovascular disease should be careful. Some people have allergic reactions such as nausea and vomiting, headache and dizziness, abdominal cramps and systemic urticaria after eating. This is the effect of bromelain contained in pineapple. This is a proteolytic enzyme that increases the permeability of the gastrointestinal mucosa and allows the gastrointestinal macromolecular proteins to penetrate into the blood, causing gastrointestinal and even systemic allergic reactions.

Control measures: avoid fasting overeating, avoid eating fresh products, avoid eating hard and uncooked products; cut the peel, scales and hairs before eating, slice and soak in light salt water for 30 minutes before eating.
