Can people with skin allergies eat peanuts?

If you have skin allergies, be a little cautious with peanuts. If you have never been allergic to peanuts, eating them while having a skin allergy should not be a problem. Peanuts have high nutritional value and can be compared to animal foods such as eggs, milk, and meat, earning them the nickname "longevity fruit." Traditional Chinese medicine says that peanuts can strengthen the spleen and stomach and moisten the lungs to reduce phlegm. Clinically, we still see patients who are allergic to peanuts. Therefore, if you have been allergic to peanuts before, you should avoid eating them.

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.

What should I do if I have skin allergies and itching?

Skin allergies and itching require actively searching for the triggering factors, i.e., allergens. Identifying what has irritated the skin and caused the allergic reaction is crucial, then avoiding further contact to prevent recurrence or worsening of the condition. If the allergy is triggered by consuming fish, shrimp, seafood, tropical fruits, etc., it is important to avoid eating similar foods in the future. If the use of certain cosmetics or skin care products causes allergies, avoid using other products containing the same ingredients. If the allergy is caused by certain medications, typically appearing within four days to a month of usage, it is advised to switch medications and avoid taking the same one again. For more severe allergic symptoms, such as significant itching, oral antihistamines like loratadine, desloratadine, cetirizine, and ebastine can be taken. Topical anti-itch medications like calamine lotion can be used, and for more severe conditions, topical corticosteroids or tacrolimus ointment can be applied. If symptoms do not improve or worsen with the aforementioned treatments, short-term oral steroids might be considered to manage the condition. (Note: Medication should be used under the guidance of a physician.)

Can people with skin allergies eat grapes?

People with skin allergies can generally eat grapes. If there is no allergic reaction to the components of grapes, eating them during an allergy period will not worsen the condition. Skin allergies are often closely related to diet. Consuming foods that commonly cause allergies, such as milk, eggs, seafood, fish, shrimp, and crab, can trigger allergic reactions in the body. People who are prone to allergies may also react to airborne dust, pollen, and animal fur. When experiencing skin allergies, it is important to use antihistamine medication under a doctor’s guidance and identify the cause to avoid contact and prevent recurrence. It's also advisable to avoid spicy and irritating foods when suffering from skin allergies.
