How should we as parents tell whether a child has a food allergy or a food intolerance?

Allergies are generally severe, with red rashes, itching, poor breathing, local edema, etc., and if they are intolerant, they generally only have symptoms such as bloating, excessive farts, and bowel sounds.

If we want to distinguish effectively, we must closely observe the child's every move, we can also look at the child's symptoms, and if the case is serious, we must go to the hospital for relevant diagnosis and treatment.

If it is due to food intolerance, then the child may have symptoms of diarrhea, abdominal pain, and if it is due to food allergies, it can cause symptoms such as difficulty breathing, vomiting, coughing, abdominal pain, hives, etc.

There is an essential difference between the two. Allergies should be investigated for allergens.

Food allergy is generally an acute reaction, mainly an allergic reaction caused by certain ingredients in food, the symptoms are fast and obvious, and it is an acute disease. Immediately after eating, or within 2 hours, the child will have some acute allergic discomfort reactions, usually manifested as rash, vomiting, diarrhea and other gastrointestinal symptoms, and in severe cases, the child will also have anaphylactic shock.

Food intolerances, on the other hand, are mostly chronic reactions.

Although the symptoms are similar to those of food allergies, the onset and symptoms of food intolerance are not obvious, and they often eat intolerant food, which takes hours or days to appear, and its effects can spread to all systems of the body.

In addition, food allergies are associated with immunoglobulins associated with food intolerance, with allergies associated with immunoglobulin IgE and food intolerance associated with immunoglobulin IgG.

In fact, many children are not food allergies, just food intolerances, and many parents just don't understand food intolerances, so they attribute many intolerance symptoms to food allergies, and they are different.

It is recommended to do a food intolerance test for the child first to see the results, I used the food tester test, and I can test the child at home, first find out the type of food that the child is not tolerated, and then optimize the diet structure to remove the physical discomfort caused by food from the source

Few people know about "food intolerances", and even fewer know the difference between food allergies and food intolerances, and some even think that the two are the same.

In fact, food intolerance and food allergy are two completely different diseases, and although they share many similarities in clinical presentation, they are actually very distinctly different.

Wrong perceptions can lead to wrong actions, so today I will introduce you to the difference between the two to help you understand food allergies and food intolerances.

1. Different antibodies: The most important difference between food allergy and food intolerance is that they both make the body produce completely different antibodies. In food allergies, the body produces immunoglobulin mediated by IGE; In the case of food intolerance, immunoglobulin is IgG-mediated.

To put it simply, when the body is allergic to a certain food, the body will secrete antibodies to reject and resist the food; And when the body is intolerant to a certain food, the body secretes antibodies with small G. The antibodies secreted by the two are different, and the roles they play are naturally different.

2. Different allergens: food allergens are generally proteins with relatively large molecular weight, such as eggs, milk, soybeans and other foods with high protein content, and seafood is not excluded. But food intolerances can't be generalized.

For example, many people will have diarrhea or vomiting after drinking milk, which is mostly due to the lack of lactase enzyme in the body to break down lactose, which is lactose intolerance. Up to now, the allergens that have been found are salicylic acid, lactose, etc. However, even if it is a food, its composition is quite complex, so when the body has symptoms of allergies to a certain food, it is difficult to determine the origin.

3. Different attack times: food allergies occur relatively quickly, and generally different degrees of allergic reactions will occur within a short time after eating food. For example, people who are allergic to seafood will experience numbness and swelling of their lips after just a few minutes of eating seafood.

Food intolerances usually do not develop symptoms until a relatively long time after ingestion.

However, since it has been a while since people need to work or study after eating, it is difficult for people to judge by time when the symptoms occur.

4. Different symptoms: Although the above two conditions can cause rashes, diarrhea and other digestive diseases. However, when the body becomes intolerant to a certain food, the body secretes IgG antibodies to bind to the food, and its medium molecular immune conjugates can cause an increase in glomerular filtration pressure, secondary blood pressure, and cholesterol deposition, which can lead to a series of chronic diseases in the long term, such as inflammatory bowel disease, chronic gastritis, chronic cholecystitis, and liver cirrhosis.

Now we know that the difference between food allergy and food intolerance is mainly different antibodies, different allergens, different onset times, and different symptoms. I hope you will pay attention to it, if you find allergies, you will be admitted to the hospital for examination as soon as possible, cooperate with the doctor to prescribe the right medicine, pay attention to your diet, and be vigilant against moderately and highly sensitive foods.

"In a word, it can be distinguished: food intolerance ≠ food allergy, and food intolerance is chronic food allergy.

However, the symptoms are similar, and the most common ones are almost all inflammation of the respiratory, respiratory, or digestive systems.

The big difference between the two is that food allergy is related to immunoglobulin E, food intolerance is related to immunoglobulin G, and the most obvious feature is that food allergy, rapid onset, obvious symptoms, is an acute disease, and it is easy to attract people's attention in daily life. People with allergies tend to eat very little food, and within a few minutes or 2 hours, some symptoms will appear, and moreover, it is generally a lifelong allergy.

The best way to prevent this is to avoid allergenic foods.

Food allergies account for a relatively small proportion of the population, accounting for about the total population.

In case of food intolerance, the symptoms will be more slow, usually after eating the intolerant food for several hours or even days, and the symptoms are varied and involve multi-system symptoms. The relationship between symptoms and food is not so obvious, and it is not easy to be directly detected and judged, so it will be ignored by us, and it is often the food that we like to eat and eat in large quantities for a long time. "߅

You can take your child to the hospital for a blood test or an allergen test, and you can only give your child a little food every time you give your child a meal, and observe whether the child has symptoms of allergies, if the child is short of breath or has red spots on his body, it means that the child is allergic to this food.

Look at whether the child will have red spots, acne or itchy body when eating these foods, difficulty breathing and other symptoms, because these will have a certain impact on the body, and the harm is relatively high.

The first baby is not digested well after eating, not only diarrhea, but also vomiting, the second is itchy all over the body after eating, and the body feels uncomfortable, and the third or third day is sick at both ends, and there are this symptoms after eating allergies.

If the child has acne and redness after eating food, then it proves that he is allergic to food.

And the allergens of the two conditions are also different. The allergens of food allergies are often some proteins with relatively large molecular weight, such as eggs, milk, soybeans and other foods, which are relatively high in protein, and some people will be allergic to seafood. Food intolerance is more complicated, and some people will have diarrhea or vomiting when they drink milk, which is mostly due to lactose intolerance.

The main intolerant allergens found so far are salicylic acid, lactose, and so on. If you feel unwell after eating certain foods, you must go to the hospital in time.

The difference between food intolerance and food allergy is as follows. The symptoms of food allergies are a little more severe than those of food intolerances. Food allergy refers to eating food in life, the body has a severe rejection reaction, the body will have itching, redness, rash.

After allergies, some organs will experience swelling. It takes several days for the condition to heal. Food intolerance refers to the fact that the body cannot digest a certain food normally, and eating it will affect the human body.

If you are intolerant to fat, eat fried high-fat foods. Symptoms of the digestive tract such as abdominal pain, diarrhea, vomiting may occur.

Food intolerance refers to an adverse reaction to a particular food or food component. In some patients, the body is unable to fully digest some food, which causes the body to react resistantly, resulting in a series of symptoms; A food allergy is when the immune system rejects a certain food after it has been eaten. The biggest difference between the two is that the food intolerance response is slower, the process is long, and the performance is not obvious; Food allergies have a rapid outbreak and obvious symptoms.

When the child is allergic to food, you should take the child to the hospital in time to do the corresponding **, give the child vitamin C supplementation in time to reduce allergies, and in daily life, take the child to participate in more sports, enhance the child's body resistance, and the most important thing is to avoid the child from contact with allergens.

If the child is allergic to a certain food, do not give the child any more food to prevent the child from having severe allergies, and strengthen the child's physical exercise to make the child's resistance stronger.

You need to go to the hospital for a check-up to check what the allergens are, so that you can better protect your body, eat foods that are easy to allergies, and don't eat foods that contain this ingredient.

Give your child some anti-allergy medications, and you should also take your child to the hospital for a check-up to see what kind of food he is allergic to, and he should avoid some in the future.
