More than 160 foods can cause allergies. Therein, 8 foods are principal. Many countries, such as US, Canada, EU, Japan, Australia and New Zealand obligation to write clear these components, which cause allergic on the packaging of all kinds of food:
- Cow milk
Cow milk is the main culprit causing food allergies in children. About 2-3percent of babies allergy to milk. Fortunately, in 6 years old, 90 percent of these children will completely cure.
Cow milk allergy relates to an immune response against either or both of the milk protein, including casein and whey protein. These proteins are also present in the milk of other mammals. So your baby is allergic cow milk, goat milk and sheep’s milk.
Allergic cow milk protein causes often an expression of outside skin (rash, hives, dermatitis, eczema), the gastrointestinal symptoms (abdominal pain, dyspepsia), and respiratory (breathing difficulties, asthma) within hour after using. The seriously allergic cases can cause anaphylaxis, a high risk of death. Clinically, cow milk allergy is often mistaken with cow milk intolerance. A disease has the genetic cause by enzyme deficiency lactose.
Allergic cow milk increases the risk of allergy to other foods as well as a nasal allergy. Up to 10 percent of food allergies in children to cow milk. They will react with beef.
The egg is the second common cause of food allergies in children, about 1.5 percent of babies are allergic egg. This condition is rarely in adult, 80 percent of babies who escape allergic egg when they are 6 years old.
Most protein allergens belong to egg whites, while the protein in egg yolk is less allergy. The similar between egg protein and other types of eggs, people with egg allergy are usually allergic duck’s egg, swan’s egg … Using chicken meat or duck meat does not cause any trouble.
Egg allergy cause often an expression of outside skin (dermatitis, hives) and gastrointestinal (abdominal pain, nausea, vomiting). First skin reactions can occur within minutes after using egg, while the gastrointestinal expression is often a difference in the time of appearance, heavy and stretching level. Anaphylaxis and respiratory reaction (difficulty breathing, coughing, asthma) after eating eggs, have also recorded.
High temperature doesn’t reduce the ability of egg allergy.
Fish allergy begins usually in adulthood, children with allergy get rarely rid of this situation. Common diseases occur in which people eat fish.
Although fish is very diverse, allergic components of all kinds of fish are protein parvalbumin. People respond with a fish, they are also allergic to other fish.
Fish allergy cause often an expression of outside skin and digestive. It appears immediately after eating. Sometimes there may be systemic reactions, including anaphylaxis.
High temperature doesn’t destroy the allergy of parvalbumin. So you should avoid eating fish. This is the only method to prevent.

Allergic symptoms include mild local reactions in the mouth (oral and throat itching) to systemic reactions, life-threatening. Sometimes there may express of gastrointestinal and respiratory.
High temperature doesn’t reduce allergic of this food group. So children with allergy should avoid all kinds of shrimp and crab.
0.4 percent children get allergic wheat. About 80 percent will completely treat when they are 6 years old. Wheat allergy is an especial reaction of the immune system with some protein in wheat.
The expression includes often mild local reactions of the skin, throat, and intestines; anaphylaxis are rare. Difficult to distinguish the clinical symptoms by allergic cause with case of gluten intolerance or gluten malabsorption syndrome (Celiac disease). Gluten intolerance causes heavy gastrointestinal symptoms. However, it does not cause hurt intestines as Celiac disease. Gluten is a protein kind in wheat, oats, barley, rye…
