How to naturally boost production of the histamine degrading DAO enzyme

DAO boosting nutrients
Please bear in mind that some foods are only high histamine because of bacteria contamination or spoilage. Any kind of virus or bacteria will stimulate an inflammatory release of histamine. This is why fermented foods are so problematic for us.Vitamin B12
Liver (I also suggest grass fed – this appears as high histamine on some lists) Salmon (fresh gutted fish or flash frozen at sea is not considered high histamine) Grass fed beef (you can do regular beef but that would be inflammatory, the grass provides the animal with omega 3 fatty acid) Eggs (duck and chicken, but they can also be inflammatory. I buy flax seed or pastured chicken eggs only) Chicken (inflammatory so I don’t eat it, pastured may be less so)Phosphorus
Sunflower seeds (some websites list these as high histamine) White beans Mung beans Grass fed beef Almonds Brown rice Broccoli Eggs (uncooked egg white is a histamine/mast cell trigger. Ask your doctor if duck eggs might be alright for you)Long chain/Omega fatty acids
Olive oil is an excellent source of long chain fatty acids. It’s also higher in the monounsaturated fat than vegetable oils, which means it’s less prone to oxidation (we don’t want that which is why we eat antioxidant foods like blueberries). I eat about a pound of salmon a week for the omega 3 fatty acids. I prefer not to take supplements due to the oxidation of the oil. If you take them, make sure to add in an antioxidant or buy one that comes with it in the capsule.Calcium
I’ve left out dairy because it’s highly inflammatory and casein is a mast cell trigger Sesame seeds (listed on some sites as high histamine) Collared greens Mustard greens Beet greens Broccoli Chard Salmon (wild caught is best if possible because farmers sometimes use antibiotics and food dye pellets to colour the salmon) Sardines (I eat them fresh only, and I mean really fresh because they are rarely gutted)Zinc
Grass fed meats and poultry (if you can find it) White beans Chickpeas Lentils Oats Salmon White fish Pistachios AlmondsMagnesium
Read the histamine magnesium post here. Chard Pumpkin seeds Kefir (fermented foods are considered high histamine) Black beans Almonds Banana (high histamine, never had a problem with them myself but always be careful please) Cacao (not high histamine but can liberate histamine from mast cells) —REFERENCES— Miyoshi, Makoto, Manami Ueno, Mari Matsuo, Yasuhiro Hamada, Michiko Takahashi, Masashi Yamamoto, Ikuko Yamamoto, Reiko Mikajiri, Satoko Tabuchi, Kumiko Wakida, Misa Yamanishi, Midori Hirai, and Makoto Usami. “Effect of dietary fatty acid and micronutrient intake/energy ratio on serum diamine oxidase activity in healthy women.” Nutrition 39-40 (2017): 67-70.
