Avocado Toast Histamine Information

The avocado toast, a popular breakfast and lunch choice, comprises mainly of avocado and bread. Avocados have been known to contain low levels of histamine. They are also not typically considered histamine liberators nor do they significantly affect the breakdown of histamine within the body, making it less likely for avocados to contribute to elevated histamine levels (1,2). Meanwhile, bread, depending on its ingredients, may vary in its relationship to histamine. Traditional bread with no yeast does not affect histamine levels and are not histamine liberators. However, any bread containing yeast, which is indeed a high histamine-content food, can increase histamine levels (3). Assuming basic avocado toast is prepared with bread that doesn't contain yeast, it stands relatively safe for consumption regarding histamine levels. However, many people add various toppings to their avocado toast which could change its histamine content. For instance, additions like tomatoes, aged cheeses, or cured meats would significantly boost the histamine level of the meal, given their high histamine content. At this time, no specific studies were found detailing a direct link between avocado toast and histamine levels. More comprehensive research is required to quantify its direct impact. For now, it is recommended to be mindful of the ingredients accompanying the avocado and bread when preparing avocado toast. References: 1. Maintz, L., & Novak, N. (2007).
