Introduction
Histamine is a natural compound found in foods and produced by the body. It plays a key role in digestion, immunity, and nervous system function. However, histamine intolerance can cause unpleasant symptoms such as headaches, digestive issues, skin reactions, and fatigue.
A low-histamine diet helps manage these symptoms by reducing foods high in histamine while emphasizing fresh, low-histamine alternatives. In this guide, you’ll learn everything you need about histamine intolerance, safe foods, foods to avoid, and a 7-day meal plan to get started.
What is Histamine Intolerance?
Histamine intolerance occurs when the body has difficulty breaking down excess histamine, leading to symptoms such as:
🔹 Headaches or migraines
🔹 Skin rashes, itching, or hives
🔹 Digestive problems (bloating, nausea, diarrhoea)
🔹 Fatigue and brain fog
🔹 Nasal congestion or asthma-like symptoms
This happens due to low levels of diamine oxidase (DAO)—the enzyme responsible for breaking down histamine in the gut. Following a low-histamine diet can reduce symptoms and improve overall well-being.
How a Low-Histamine Diet Works
A low-histamine diet focuses on:
✅ Fresh, unprocessed foods
✅ Low-histamine fruits and vegetables
✅ Lean proteins that are freshly cooked
✅ Dairy alternatives (coconut or almond milk)
✅ Avoiding leftovers and fermented foods
Sticking to low-histamine foods and avoiding histamine-rich triggers can help your body maintain better histamine balance and feel better.
Best Foods for a Low-Histamine Diet
1. Fresh Proteins (Low-Histamine Sources)
🐓 Fresh meats (chicken, turkey, fresh-caught fish) – Cook immediately
🥚 Egg yolks (avoid egg whites if sensitive)
🌱 Plant-based proteins (quinoa, white beans, lentils in moderation)
2. Safe Fruits
🍏 Apples & pears – Gentle on digestion
🍌 Bananas (in moderation) – Can trigger in some people
🍇 Blueberries & mangoes – Rich in antioxidants
3. Safe Vegetables
🥒 Zucchini & cucumbers – Refreshing and anti-inflammatory
🥕 Carrots & sweet potatoes – Great for gut health
🥬 Lettuce, cabbage, and asparagus – Nutrient-dense
4. Dairy Alternatives
🥛 Coconut milk & almond milk are good alternatives to regular milk
🧀 Dairy-free cheeses – Choose non-fermented options
5. Herbs & Spices (Anti-Inflammatory Options)
🌿 Basil, oregano, thyme, parsley – Flavorful and safe
🌱 Ginger & turmeric – Help digestion and inflammation
Foods to Avoid (High in Histamine)
🚫 Aged & Fermented Foods – Cheese, yoghurt, kombucha, sauerkraut
🚫 Processed & Smoked Meats – Bacon, salami, hot dogs
🚫 Certain Vegetables – Tomatoes, spinach, eggplant, avocados
🚫 Caffeinated & Alcoholic Drinks – Coffee, wine, beer, tea
🚫 Leftovers & Pre-Cooked Meals – Histamine builds up in stored food
Avoiding these foods can help reduce histamine overload and ease symptoms.
