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.
