Vitamin C Vitamin C boosts the immune system. It also acts as a natural antihistamine. According to a 2018 study on vitamin C in the treatment of allergies, oxidative stress plays a key role in allergic diseases. As vitamin C is a powerful antioxidant and anti-inflammatory, it may act as a treatment for allergies.
Common ones are stinging nettle, vitamin C, quercetin, butterbur, bromelain, and probiotics. Some alternative practices—such as acupuncture, nasal irrigation, and exercise—may also help you manage symptoms.
Vitamin C is a natural antihistamine, which means it can lower histamine levels and mitigate allergic reactions and symptoms. Consume plenty of Vitamin C rich foods, like tropical fruits, citrus fruits, broccoli and cauliflower, and berries.
Drinking plenty of water every day is essential for all bodily functions, including the regulation of histamine levels. Water does aid in the removal of histamines from the body as more that 95% of excess histamines are removed from the body through the urine.
Vitamin B6 and Vitamin C, in particular, have been shown to reduce symptoms of seasickness and histamine intolerance.
Bananas are not directly high in histamine, but many people have reported that bananas are still a trigger for their histamine intolerance symptoms. Such a food is known as a “histamine liberator,” and should therefore be treated like a high histamine food.
Honey has been used for medicinal purposes around the world for thousands of years. It may help some people manage their allergy symptoms, but there isn't enough evidence to show that it can replace antihistamines and other standard allergy treatments.
Helps Fight Allergies: Red Apples
An apple a day keeps the allergist away. Red produce like apples contains a compound called quercetin. This compound is responsible for the red color and works as a natural antihistamine in your body.
Allergists recommend long-acting, non-sedating antihistamines — ones that won't make you sleepy — for everyday use. Though you may know them by their brand names, the generic versions tackle the same problems: Cetirizine (Zyrtec®, Aller-Tec®, Wall-Zyr®). Fexofenadine (Allegra®, Aller-ease®, Aller-Fex®, Wal-Fex®).
High Histamine Foods
Fruit: Citrus fruits, strawberries, bananas, pineapple, pears. Vegetables: Eggplant, avocado, tomatoes, olives, beans. Dairy: Cheese, yogurt, processed cheese.
Is coffee an antihistamine? No, coffee is not an antihistamine, but it's generally considered to not be good for those with histamine intolerance.
Coffee contains histamines in low amounts, but for people who are sensitive to them, it contains plenty to get a reaction out of them. While the natural histamine content in coffee is low, some coffee processes can increase histamine levels.
Your body releases higher levels of histamine naturally at night as well as after meals so taking activated charcoal at night (about two hours after an early dinner) sweeps up excess histamine and can alleviate some, if not all of the symptoms associated with high histamine at night.
Avocados are naturally very high in histamine and such high levels can be problematic for people with histamine intolerance. If you suspect that you may have histamine intolerance, it is best to avoid foods high in histamine, such as avocados.
Vitamin C is a powerful antioxidant and anti-inflammatory that helps reduce histamine levels by acting as a natural antihistamine and stabilizing mast cells. This can help alleviate allergy symptoms such as runny nose, itchy eyes, and wheezing.
Citrus Fruit
Though citrus fruits such as lemons, limes, and oranges are not actually high in histamine, they can trigger the release of histamine in your body. Many health care professionals recommend limiting citrus fruits and juices as part of a low-histamine diet.
So, water actually has the power to regulate your histamine levels. This does not mean drinking water can act to prevent or treat an allergic reaction, but it's good to know that avoiding dehydration by drinking water will help to maintain normal histamine activity.
Eggs are low in histamines, this makes them ideal for the low-histamine diet. Chickpeas, peanuts, and lentils have been found to have low concentrations of histamines and may be safely consumed in a low-histamine diet.
Histamine levels are another potent downstream target. Allergic symptoms exacerbate during nighttime and plasma histamine levels exhibit nocturnal peaks.
