Plums are stone fruits rich in fiber, antioxidants, vitamin C, and natural sugars. They are consumed fresh or dried (as prunes) and are commonly used to support digestion. The Plum marker on the 1019 IgG Food Antibodies – Bloodspot panel measures IgG antibodies directed against plum proteins. IgG antibodies indicate immune recognition following exposure. They do not diagnose an IgE-mediated fruit allergy and should not be interpreted as a standalone reason for permanent elimination.
Plums and prunes are naturally high in sorbitol and fermentable carbohydrates, which can cause bloating, gas, or loose stools in sensitive individuals independent of immune reactivity. Therefore, digestive symptoms after eating plums may be related to carbohydrate intolerance rather than IgG-mediated response.
Some individuals with elevated plum IgG levels report delayed symptoms such as bloating, abdominal discomfort, headaches, fatigue, skin irritation, or sinus congestion after consumption. Because plums are often eaten seasonally or in dried form, symptom tracking can be especially helpful in determining relevance.
