People with skin allergies should avoid eating crab. Crab is cold in nature and salty in taste, containing a rich array of trace elements and is a high-protein food. Traditional Chinese medicine believes that crab has the effects of clearing heat, relaxing tendons and activating blood circulation, and facilitating joints. However, it is also considered a product that can activate internal wind, classified as an allergenic food. Similarly, Western medicine recognizes crab as a form of foreign protein. Clinically, we have seen patients who are allergic to crab, so for those with skin allergies, we do not recommend eating crab.

Does skin allergy affect pregnancy?

When skin allergies occur, they do not affect the normal chances of pregnancy, but they do have some impact on the fetus after pregnancy. This is because skin allergies are reactions to certain allergens, and the response to allergens varies from person to person. Some individuals might have a higher sensitivity, while others may show little to no symptoms. Beyond the impacts these allergic reactions have on the body, there is also the use of medicinal solutions for treatment during allergic episodes. It is advised to identify the allergen causing the skin allergy before trying to conceive, and to avoid it as much as possible while planning for pregnancy.

Can you eat fish if you have a skin allergy?

Skin allergies are primarily caused by contact with allergens, resulting in skin conditions. Fish, being a stimulating food with a strong smell, belongs to the category of irritants. Therefore, it is best to avoid eating fish during an allergic reaction period as it might worsen the skin allergy. During this time, it is preferable to consume foods that aid in digestion and are lighter, such as vegetables.
