Pineapple, for one, boasts some impressive natural anti-histamine properties as a result of its bromelain content. The enzyme bromelain from pineapple has been found in some preliminary research to display anti-inflammatory and anti-allergic properties, which could literally help desensitise your airways to allergens.
One of the most common allergy-causing substances in pineapples is called bromelain. When someone with an allergy to pineapple (or other foods with this compound) consumes this fruit, their body interprets bromelain as a foreign invader and triggers a release of histamines in an attempt to fight it off.
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.
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.
These histamine liberators include kiwi fruit, strawberries, bananas, papaya, citrus fruits and pineapple as well as food additives like carrageenan; certain foods are known to block the activity of the enzyme that is involved in breaking down histamine – an enzyme called diamine oxidase (DAO).
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.
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.
Pineapple is one of the foods that help with allergies. It's full of healthy vitamin C, but the fruit's true allergy powerhouse is an enzyme called bromelain. And guess what? This enzyme fights inflammation to help reduce the swelling and irritation brought on by pollen and other seasonal allergens.
“Antihistamines” control allergy symptoms by blocking histamine activity. But our body can also produce enzymes such as histamine-N-methyltransferase and diamine oxidase (DAO) capable of inactivating histamine.
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.
They reported that pretreatment of honey (0.5, 1, and 2%) was able to inhibit the release of histamine in a concentration-dependent manner.
The histamine released during exercise appears to result from mast cell degranulation, as well as de novo synthesis of histamine. This response, a fundamental element of exercise, seems to comprise an anaphylactoid reaction and not an allergic reaction to exercise.
Polyphenols derived from apples have been reported to suppress histamine release from rat cells, reduce auricular swelling in allergic mice, and alleviate skin inflammation in atopic patients.
Bromelain is a mixture of proteolytic enzymes derived from pineapple (Ananas comosus) fruit and stem possessing several beneficial properties, particularly anti-inflammatory activity.
The juice from unripe pineapples can cause severe vomiting. Bromelain ingestion is associated with a low incidence of adverse reactions, including diarrhea, excess menstrual flow, nausea, skin rash, and vomiting. Swelling of the mouth and cheeks can result from eating large amounts of the fruit.
Natural antihistamines may help you control your seasonal 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.
– Ginger: As a powerful anti-inflammatory, ginger has the ability to reduce the release of endogenous histamine, a mechanism that occurs in allergies.
Second- and third-generation antihistamines are less likely to cause drowsiness. Of these, cetirizine works the fastest but has a higher chance of making you feel drowsy.
High Histamine Foods
Fruit: Citrus fruits, strawberries, bananas, pineapple, pears. Vegetables: Eggplant, avocado, tomatoes, olives, beans. Dairy: Cheese, yogurt, processed cheese.
Greg Panico, a spokesman for Janssen Pharmaceutica, which is owned by Johnson and Johnson, said that the withdrawal was a voluntary business decision. “The decision to voluntarily discontinue it recognises that the allergy marketplace is crowded with a number of other drugs,” Mr Panico said.
