Is Bacon High in Histamine? Understanding the Relationship


Bacon is a beloved and versatile ingredient in many dishes, but for individuals with histamine intolerance, concerns about its histamine content may arise. In this article, we will delve into the question of whether bacon is high in histamine and explore the factors that contribute to histamine levels in this popular meat.

Histamine and Bacon

Histamine is a compound naturally found in certain foods and is also produced by bacteria during fermentation and aging processes. It can lead to adverse symptoms when the body has difficulty metabolizing or clearing histamine, causing histamine intolerance. Thus, those with histamine intolerance often need to be mindful of their dietary choices.

Histamine Content in Bacon

Due to various factors related to its manufacturing and processing methods, bacon is considered a high histamine food.

The Histidine Conversion

The histidine content of pork, the meat used to produce bacon, can be readily converted into histamine by bacteria containing the enzyme histidine decarboxylase. This conversion process occurs during the long period of time involved in manufacturing bacon.

Manufacturing Process and Histamine Formation

The manufacturing process of bacon involves aging and microbial fermentation for preservation, which can lead to the production of histamine. The meat is left to cure for weeks or even months in refrigeration, allowing for a significant rise in histamine levels. Unlike living tissue, the pork used for producing bacon does not contain the neutralizing enzymes capable of destroying histamine. This allows for the accumulation of histamine in the meat that is consumed.

Grilling and Histamine Levels

When cooking bacon at high temperatures before consumption, histamine levels are known to increase. The heat applied during cooking can further raise histamine levels, potentially aggravating symptoms in individuals with histamine intolerance. Therefore, those with specific dietary concerns should be mindful of bacon consumption.

DAO Inhibition

By acting as a DAO inhibitor, bacon can also affect histamine levels. DAO (diamine oxidase) is the enzyme responsible for degrading histamine in our bodies. When DAO is inhibited, it compromises histamine clearance, leading to higher histamine levels and potential symptoms.

Nitrates and Histamine Liberation

Nitrates, commonly used in the manufacturing of bacon as a preservative and flavor enhancer, can act as histamine liberators. Some studies have linked nitrates to increased blood levels of histamine in certain individuals, potentially leading to symptoms such as headaches or migraines.

Managing Histamine Intolerance and Bacon Consumption

For individuals with histamine intolerance, managing bacon consumption may be necessary to minimize symptoms. Here are some tips to consider:

1. Freshness

Choose fresh, uncured bacon whenever possible. Freshly prepared bacon is less likely to have accumulated higher levels of histamine during the curing and aging processes.

2. Moderation

Consume bacon in moderation, especially if you are sensitive to histamine. Balancing your overall histamine load is key to managing symptoms.

3. Cooking Methods

Consider alternative cooking methods for bacon, such as baking or low-heat cooking, to minimize histamine formation.

4. Individual Sensitivity

Pay attention to your body’s individual response to bacon. Keep a food diary to track any symptoms or reactions that may occur after consuming bacon or other histamine-rich foods.


In conclusion, bacon is considered a high histamine food due to the histidine conversion process, the manufacturing methods involved, and the potential for histamine formation during cooking. For individuals with histamine intolerance, it is important to be mindful of bacon consumption and consider alternative options to minimize symptoms. As always, consulting with a healthcare professional or registered dietitian specializing in histamine intolerance can provide personalized guidance and support tailored to your specific needs and concerns.
