Histamine is a biogenic amine that plays a crucial role in various physiological functions, including immune response, gastric acid secretion, and neurotransmission. However, excessive intake of histamine through food can lead to adverse health effects, particularly in individuals with histamine intolerance or certain medical conditions such as atopic dermatitis and asthma. This article explores the impact of histamine-rich foods on health, drawing on findings from recent research studies.
Histamine and Atopic Dermatitis
Atopic dermatitis (AD) is a chronic inflammatory skin condition that can be exacerbated by dietary histamine. A study investigated the role of ingested histamine in patients with AD by having them follow a histamine-free diet for one week, followed by histamine provocations. The results showed that 12 out of 36 patients experienced significant improvement in their condition after the diet, and 11 out of 36 showed aggravation of eczema after histamine provocation1. This suggests that dietary histamine can worsen symptoms in a subset of AD patients.
Histamine Intolerance in Healthy Individuals
Histamine intolerance can manifest as various symptoms, including diarrhea, hypotension, headache, pruritus, and flush. A study conducted on healthy female volunteers found that 75 mg of pure liquid oral histamine could provoke immediate and delayed symptoms in 50% of the participants, despite them having no history of food intolerance2. This indicates that even non-toxic doses of histamine in food can cause intolerance-like symptoms in healthy individuals.
Histamine and Food Allergies in Children
Children with atopic dermatitis often exhibit hypersensitivity to certain foods, which can lead to increased plasma histamine levels. A study involving double-blind placebo-controlled food challenges in children with AD found that positive food challenges resulted in significant rises in plasma histamine concentrations, implicating mast-cell or basophil mediators in the pathogenesis of food allergies3. This highlights the role of histamine in allergic reactions to food in children with AD.
Impact on Asthma
Dietary histamine intake can also affect asthma symptoms. A pilot study on children with mild intermittent asthma revealed that a high-histamine diet led to significantly higher mean air flow obstruction and more severe symptoms compared to a low-histamine diet4. This suggests that dietary histamine may exacerbate asthma symptoms, making diet management a potential strategy for asthma control.
Histamine and ADHD
Food additives that release histamine can exacerbate ADHD symptoms in children. A study found that genetic polymorphisms affecting histamine degradation moderated the adverse effects of food additives on ADHD symptoms5. This indicates that histamine may mediate the effects of food additives on ADHD, and genetic factors can influence individual responses.
Histamine Release from Basophils
Patients with food hypersensitivity and atopic dermatitis have been shown to have higher rates of spontaneous histamine release from basophils. A study found that dietary elimination of relevant food antigens significantly reduced histamine release, suggesting that dietary management can help control histamine-mediated symptoms in these patients6.
Effects on Digestive Physiology
High levels of dietary histamine can impair digestive physiology and muscle quality in animals. A study on hybrid grouper fish found that increased dietary histamine levels led to decreased digestive enzyme activities, damaged gastric and intestinal mucosa, and reduced muscle quality7. This indicates that excessive histamine intake can have detrimental effects on digestive health.
Antiallergenic Properties of Chongkukjang
Chongkukjang (CKJ), a traditional Korean fermented soybean product, has been shown to reduce histamine-induced skin wheal responses in healthy participants. A randomized, double-blind, placebo-controlled trial found that CKJ supplementation significantly reduced skin wheal areas compared to placebo, suggesting its potential as a functional food to suppress allergies8.
Insufficient Histidine Intake and Anxiety
Histidine is a precursor of histamine, and insufficient intake can reduce brain histamine levels, leading to anxiety-like behaviors. A study on mice demonstrated that a low-histidine diet resulted in lower brain histamine concentrations and increased anxiety-like behaviors, highlighting the importance of adequate histidine intake for mental health9.
Counteracting Histamine’s Negative Effects
Oligomeric proanthocyanidins (OPCs) have been found to counteract the negative effects of high dietary histamine in American eels. A study showed that OPC supplementation alleviated growth retardation and improved serum biochemical parameters, suggesting that OPCs could be a potential feed additive to mitigate histamine’s adverse effects10.
Conclusion
Histamine-rich foods can have significant health impacts, particularly for individuals with histamine intolerance, atopic dermatitis, asthma, and other conditions. Understanding the role of dietary histamine and managing its intake can help mitigate adverse symptoms and improve overall health. Further research is needed to explore effective dietary interventions and potential therapeutic agents to counteract the negative effects of histamine.
