Is Coffee a Source of Histamine? Understanding the Potential Link


Coffee is a beloved beverage worldwide, cherished for its rich aroma and ability to perk us up in the mornings. However, many individuals may find themselves wondering if coffee could actually be a source of histamine. Histamine is a naturally occurring compound that plays a crucial role in our body’s immune response, causing symptoms like itching, sneezing, and congestion when released in excess. In this article, we will delve into the potential link between coffee and histamine, shedding light on whether coffee can be considered a source of histamine.

The Role of Histamine in the Body

Histamine is a chemical messenger that is produced by the body’s immune cells called mast cells. It acts as a crucial mediator in various physiological processes such as inflammation, gastric acid secretion, and neurotransmitter regulation. When histamine is released in small quantities, it plays a beneficial role in our body. However, excessive histamine release can result in allergic reactions and other unfavorable symptoms.

Histamine Intolerance: A Brief Explanation

Histamine intolerance is a condition characterized by an individual’s inability to adequately break down histamine in their body due to insufficient levels of the enzyme diamine oxidase (DAO). This enzyme is responsible for breaking down histamine consumed through food and other means. Consequently, individuals with histamine intolerance may experience adverse effects even with normal levels of histamine intake, leading them to question the histamine content of coffee.

Does Coffee Contain Histamine?

While coffee does contain histamine, the concentration is typically minimal and unlikely to trigger histamine intolerance symptoms in individuals with normal histamine metabolism. The histamine content in coffee primarily stems from its raw materials, such as the coffee bean itself. During the roasting process, however, a significant portion of the histamine is destroyed. Therefore, the histamine levels in a typical cup of coffee are generally considered to be too low to cause histamine intolerance symptoms.

Factors Influencing Histamine Levels in Coffee

Although coffee itself may contain minimal histamine, certain factors can influence the overall histamine levels in a cup of coffee. For instance, the brewing method and duration can affect histamine levels. Coffee brewed with a longer steeping period or stored for a prolonged duration may have slightly higher histamine content. However, it is important to note that these levels remain significantly lower than those found in other histamine-rich foods, such as aged cheeses or fermented products.

Individual Sensitivity and Histamine Response

While coffee may not pose a significant histamine-related concern for most individuals, it is essential to recognize that everyone’s tolerance and sensitivity levels vary. Some individuals may be more prone to histamine-related symptoms due to underlying conditions or genetic factors. If someone suspects they have histamine intolerance or experiences adverse reactions after consuming coffee, it is advisable to consult a healthcare professional for further evaluation and guidance.

Coffee and Adrenaline Production

Apart from its potential histamine content, coffee can also stimulate the production of adrenaline in the body. Adrenaline, also known as epinephrine, is a hormone released by the adrenal glands in response to stress or excitement. It acts on various body systems, accelerating heart rate, increasing blood pressure, and boosting energy levels. Many individuals consume coffee for its energizing effects, which can be attributed to the release of adrenaline.

Adrenaline and Its Effects on Histamine Release

Interestingly, adrenaline can influence the release of histamine in the body. When adrenaline levels rise, histamine release from immune cells decreases. Consequently, individuals who experience the energizing effects of coffee due to heightened adrenaline stimulation may indirectly benefit from a reduced histamine response.

The Caffeine Factor

Caffeine, a well-known stimulant found in coffee, is responsible for triggering the release of adrenaline. By binding to adenosine receptors in the brain, caffeine inhibits the calming effects of adenosine, leading to increased neuronal firing and adrenaline release. However, it is important to note that caffeine’s effects on adrenaline production may vary from person to person, and some individuals may be more sensitive to its stimulating effects than others.


In conclusion, while coffee does contain histamine, its concentration is typically too low to cause histamine intolerance symptoms in individuals with normal histamine metabolism. Factors such as brewing methods and storage duration may influence histamine levels in coffee, but they remain significantly lower than those found in other histamine-rich foods. Moreover, the adrenaline-stimulating effects of coffee may indirectly inhibit histamine release in the body. However, it is crucial to recognize that individual sensitivity and response to coffee can vary, and individuals with suspected histamine intolerance should consult a healthcare professional for personalized advice. Ultimately, for most coffee lovers, their daily cup of joe can be enjoyed without significant concerns regarding histamine intake.
