When individuals do not know of the protein-immune-system connection, they concoct a variety of theories by what actually causes food allergies. A few of these theories are valid to particular point, others rarely apply, and some are simply plain bunk.
Can genetically engineered foods trigger allergies? They sure can, even though occurrences are rare. To genetically engineer a food, scientists introduce genetic material from one food into another. When they mistakenly introduce an allergenic protein from one food into another, the receiving food also includes the allergenic protein, which could also trigger a reaction.
Throughout an allergic attack, your immune system produces histamines that trigger symptoms, therefore it makes sense that consuming histamines would trigger similar symptoms, and consuming histamines sometimes does just that. Several foods contain histamine or histamine-like substances that belongs to them:
Scombroid fish: The Scombridae family of fish, including tunas and mackerels as well as their close cousins, bluefish and mahi-mahi, have a toxic histamine generated by bacterial degradation of substances in the muscle protein. This natural spoilage process is believed release a additional by-products that intensify the toxic effect and may cause scombroid poisoning.
Strawberries: Those who have "allergic reactions" to strawberries in many cases are simply more responsive to the histamines they contain.
Tomatoes: When tomatoes produce symptoms much like the ones from a hypersensitive reaction, histamines might be at fault.
Chocolate: A food allergy to chocolate is rare, but chocolate could have higher amounts of histamines that can trigger allergic-like symptoms.
Wine and beer: Some wines and beers contain elevated amounts of histamines. Wine producers have grasped this plus some now offer histamine-low or histamine-free wine. Red wines typically contain more histamines than white wines.
The amount of histamine present in these food types are often incompetent at causing reactions however they can and occasionally do cause allergic-like reactions. Scombroid poisoning may cause severe reactions, but reactions with other foods that contain elevated histamine levels are usually mild, when they even occur.
