What do you know about food intolerance and what is different from a food allergy?

Food reactions are common, but most are caused by a food intolerance rather than a food allergy. A food intolerance can cause some of the same signs and symptoms as a food allergy, so people often confuse the two.

A true food allergy causes an immune system reaction that affects numerous organs in the body. It can cause a range of symptoms. In some cases, an allergic food reaction can be severe or life-threatening. In contrast, food intolerance symptoms are generally less serious and are limited to digestive problems.

what i know about food tolerance  is that some people don't have enzymes in their bodies that they can't  digest some type of food moleculs such as lactose intolerance so these is a type of food intolerance that the persone's body can't produce the β-galactosidase wich digest the molecule of lactose so this person will vomit everytime when he or she drinks milk, about food allergy i don't have clear information but i guess that the food molecules causes allergies while interaction with the body anticorps so their bodies behaves the same as if it's a bacterias or virus (well i'm not sure but this is my analysis hhh :) )

Intolerance is digestive form of allergy.

While allergical reaction is hypersensation against protein agent makes the body produce more histamine that causing blood patches under skin in the form of itching and periferal vasodilatation may lead to death in severe cases.

Food intolerance is known that food can cause many different types of reactions in the body.  These may be evident in the skin (such as hives, rashes, itchiness, or swellings); the gut (such as reflux, vomiting, tummy pains, wind, diarrhoea, and constipation); when breathing (such as shortness of breath or a tight chest) or through generally feeling unwell.  Some people put up with symptoms for years, which could get better if the foods causing these symptoms were cut out of the diet.

If you have a food allergy, even a tiny amount of the offending food can cause an immediate, severe reaction. Digestive signs and symptoms may include nausea, vomiting, cramping and diarrhea. Other signs and symptoms can include a tingling mouth, hives, and swelling of the lips, face, tongue and throat. A life-threatening allergic reaction known as anaphylaxis can cause breathing trouble and dangerously low blood pressure. If you have a food allergy, you'll need to avoid the offending food entirely.

Food intolerance (or non-allergic food hypersensitivity) is a detrimental reaction, often delayed, to a food, beverage,food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but it is not a true food allergy. A true food allergy requires the presence of immune mechanisms (as for instance Immunoglobin E - IgE antibodies) against the food, and a food intolerance does not.

Food intolerance symptoms generally come on gradually and don't involve an immune system reaction. If you have a food intolerance, you may be able to eat small amounts of the offending food without trouble. You may also be able to take steps that help prevent a reaction. For example, if you have lactose intolerance, you may be able to drink lactose-free milk or take lactase enzyme pills that aid digestion (such as Lactaid).

Causes of food intolerance include:

·         Absence of an enzyme needed to fully digest a food.Lactose intolerance is a common example.

·         Irritable bowel syndrome. This chronic condition can cause cramping, constipation and diarrhea.

·         Food poisoning. Toxins such as bacteria in spoiled food can cause severe digestive symptoms.

·         Sensitivity to food additives. For example, sulfites used to preserve dried fruit, canned goods and wine can trigger asthma attacks in sensitive people.

·         Recurring stress or psychological factors. Sometimes the mere thought of a food may make you sick. The reason is not fully understood.

 

·         Celiac disease. Celiac disease has some features of a true food allergy because it does involve the immune system. However, symptoms are mostly gastrointestinal, and people with celiac disease are not at risk of anaphylaxis. This chronic digestive condition is triggered by eating gluten, a protein found in wheat and other grains.

Allergies in general defined as an immediate response to any stimulus, in response to which the immune system produces antibodies against molecules offenders.

 

During intolerance suggest slow reaction to food (often it occurs only in a few days), which manifests itself in the form of a variety of symptoms, the first opinion, even unrelated

Food intolerance is known that food can cause many different types of reactions in the body.  These may be evident in the skin (such as hives, rashes, itchiness, or swellings); the gut (such as reflux, vomiting, tummy pains, wind, diarrhoea, and constipation); when breathing (such as shortness of breath or a tight chest) or through generally feeling unwell.  Some people put up with symptoms for years, which could get better if the foods causing these symptoms were cut out of the diet.

Enjoy fruits, whole grains and milk have beneficial effects for health, but it may also be the cause of some health problems, so if a person could not afford some of the contents, which is known medically not afford food. The disease is not dangerous, but can live with it; where the patient can continue to eat foods that cause trouble, but in limited quantities, unlike what happens when food allergy. The German nutrition scientist Harald Seitz: "When the injury not to carry food the patient is suffering from allergic responses as a result of intolerance to certain types of foods due to the inability of the body's ability to address some of the components of this food and absorbed properly." He explained Seitz, an expert with the consumer information center aid the city of Bonn, that the cause of the injury not to carry certain types of food is due mostly to a congenital deficiency in digestive enzymes, pointing out that it may also arise as a result of certain intestinal diseases or as a result of changes in Flora intestine. For its part, the German nutrition expert Doreen Nadenh Hecht confirmed, that the incidence of non-food intolerance does not require cutting out eating foods that cause them fully, contrary to what occurs when a food allergy, which is often confused with food intolerance. Sensitivity or intolerance? And the difference between food allergy and food intolerance, Hecht, a member of the German Society for Nutrition, said: "When allergies issued immune system allergic responses to some of the substances found in food, which is suffering patient of sensitivity towards him, and configures the antibodies to it, knowing that few quantities of the causes of fumbling enough for the emergence of severe and immediate allergic responses. " But when the injury not to carry food, orders from the response resulting from eating, which the body is not able to afford the intensity, the amount of the food itself also vary from satisfactory to another case. And pick up a nutrition scientist German Bettina Halbach party talk, pointing out that the symptoms of food intolerance not to show a little bit late and be less severe allergy symptoms, knowing that often appear in the image of the digestive system troubles. Halbach and stressed the need to take the risk not to carry food seriously, warning, saying: "If a patient does not avoid eating foods that are not borne by, then he can not get rid of the trouble caused by them easily, and will worsen the situation." It also underestimated the disease can lead to injury for many health problems; where they can cause damage, for example, membrane mucous lining of the stomach and intestines, leading for example to the incidence of disturbances in the body's absorption of food and increased susceptibility to infection as well as infections. So Halbach stressed the need to pay attention to signs warning function on this disease and response immediately. , And in order for the patient to discover the quality of food that cause him trouble in the incidence of those, the German expert recommended foods covered by the registration of a day in the notebook, should also consult a doctor and undergo necessary to clarify the cause of this trouble accurately tests. If the injury has been verified not to carry a certain quality of the foods on the basis of the results of the examination, then the food should be adjusted to the patient behavior commensurate with its ability to endurance.
