Histamine, a biogenic amine found in various food products, is frequently implicated as a potential instigator of a range of health issues. [1] These issues are often collectively referred to under the umbrella term "histamine intolerance", [1] formulated drawing parallels to "lactose intolerance", a condition resulting from lactase enzyme deficiency.
Allergies are hypersensitivity reactions of the immune system to specific substances called allergens (such as pollen, stings, drugs, or food) that, in most people, result in no symptoms. Trees within the order Fagales possess particularly potent allergens, e.g. the prototypical Bet v 1, the major white birch ( Betula verrucosa - now called B ...
During that time, many dietitians advised that a diet devoid of histamine-liberating foods was the ideal strategy to prevent symptoms of histamine intolerance from manifesting. Lists of foods deemed to be histamine-liberating were published in various scientific articles, which included fermented sausages, cured cheese, wine and beer. [11]
The quantitative allergy blood result can help determine what a patient is allergic to, help predict and follow the disease development, estimate the risk of a severe reaction, and explain cross-reactivity. [118] [119] A low total IgE level is not adequate to rule out sensitization to commonly inhaled allergens. [120]
During pregnancy, DAO helps maintaining fetal growth and development by regulating histamine levels. [11] DAO levels in the blood circulation increase vastly in pregnant women suggesting a protective mechanism against adverse histamine. [12] Histamine is a potent vasodilator and can cause uterine contractions, which can lead to premature labor.
Experts agree that a diet rich in fruits and veggies is the way to go. Fruits can provide essential nutrients, fiber and a host of other health benefits. If you enjoy fruits frequently, that's great.
Soda and juices wreak havoc on blood-sugar levels. Add some interest to seltzer by squeezing in fresh citrus, opting for flavored (but not sweetened) versions, or infusing with a sprig of fresh herbs.
In type I hypersensitivity, B cells are stimulated (by CD4 + T h 2 cells) to produce IgE antibodies specific to an antigen. The difference between a normal infectious immune response and a type 1 hypersensitivity response is that in type 1 hypersensitivity, the antibody is IgE instead of IgA, IgG, or IgM.
