This blog post aims to delve into the evidence and provide a comprehensive understanding of whether sweet corn is low histamine.

What is Histamine Intolerance?

Histamine intolerance occurs when the body accumulates excess histamine, leading to symptoms such as headaches, flushing, nausea, and digestive issues. The root cause can vary, including enzyme deficiencies, gut dysbiosis, and certain medical conditions.

Histamine Content in Sweet Corn
