High fructose corn syrup allergy

What you need to know about high fructose corn syrup allergy

Many people report discomfort after consuming foods containing high fructose corn syrup (HFCS), but the term high fructose corn syrup allergy can be misleading. True food allergies involve an immune response to specific proteins, which HFCS, as a sugar-based ingredient, does not contain. Instead, most issues are related to high fructose corn syrup intolerance or high fructose corn syrup sensitivity, both of which involve digestive difficulties rather than an immune reaction.

Understanding Intolerance and Sensitivity

A high fructose corn syrup intolerance is a condition where the body struggles to absorb and process fructose, a type of sugar found in HFCS, fruits, and some vegetables. This leads to symptoms like bloating, gas, diarrhea, and abdominal discomfort. These symptoms occur because unabsorbed fructose ferments in the colon, causing digestive distress.

For others, a high fructose corn syrup sensitivity may present milder symptoms. While not as severe as intolerance, it can still cause discomfort, particularly when larger amounts of HFCS are consumed.

Managing Symptoms

If you suspect corn syrup intolerance, carefully review food labels and avoid products containing HFCS. Instead, choose natural sweeteners or products labeled as HFCS-free. In cases of fructose malabsorption, incorporating dietary enzymes like xylose isomerase may help break down fructose, which helps to reduce symptoms.*

Consult a healthcare professional if symptoms persist, as they can help differentiate between a high fructose corn syrup sensitivity and other conditions like irritable bowel syndrome or fructose malabsorption.

While the term “allergy” might not be accurate, understanding your body’s response to HFCS is essential for managing symptoms.
