Can you be allergic to Red peppers but not green?

It is possible to be allergic to red peppers and not green peppers, as different varieties of plants can contain different allergens. Red and green peppers belong to the nightshade family, which also includes tomatoes, eggplants, and potatoes. Some people may develop an allergy to one or more members of the nightshade family, and the specific allergen responsible can vary.

A person may react differently to different nightshade vegetables. For instance, someone allergic to red bell peppers may tolerate green bell peppers without issue, or they may experience a milder reaction. This phenomenon is attributed to the varying concentrations and types of allergens present in different nightshade vegetables.

It's important for individuals with a known nightshade allergy to consult with an allergist to accurately identify the specific allergen and determine the extent of their sensitivity. In some cases, certain nightshade vegetables may be safe for consumption, while others should be avoided entirely to prevent allergic reactions.
