You make some good points, and I am very sympathetic of others suffering with allergies. But I am also not very tolerant of those who fake allergies to get out of things.
In the 44 years I have had a severe allergy, my radar goes up with others mention having severe allergies like mine. My immediate reaction is empathy; this person "understands". So when I see that person then indulging in the very allergen they previously said was deadly to them, it bothers me. While they may have their reasons, I can't deny that this type of behavior makes it more challenging for me and others like me to be taken seriously - and that needs to be called out.
Forgive me, but your posts - to me- appear almost dangerously ill-informed. This is supposed to be a thread about COVID, so i will try to keep this diversion short.
Food allergy reactions can manifest in a variety of ways. They can even come to manifest as food cravings. This is notoriously common for those with milk allergies. Caregivers unwittingly insist that children drink milk every day. Schools and daycare centers provide free milk and similarly insist children drink milk, because "Milk is healthy!" People (usually children) with milk allergies then get so accustomed to daily reaction cycle that their bodies crave it! Sadly these children are often diagnosed with behavior disorders, when really they are just experiencing an allergic reaction.
If that wasn't horrible enough, any person who is prone to have 1 food allergy is prone to having multiple food allergies, though not always.
On top of that, there is not truly reliable way to test for food allergies. Skin prick tests partly work, but not always. There can be false negatives and false positives. Both of these factors make food allergies hard to diagnose. Diagnoses is often only possible via an elimination diet that
lasts two full weeks. That = no wheat, milk, shellfish, nuts, coconut, egg, soy, fish, sesame. Nothing with any trace of any of these item, no eating out, and no cross contamination, and EVEN THEN a person can be allergic to ANY protein. They MIGHT be allergic to corn, gelatin, even beef or chicken!
Elimination diets are hard, because cross contamination is very easy. It can happen if a pot/pan is used to cook pasta, or a counter isn't wiped, a cup isn't properly washed. It can also happen when a food is processed/packaged.
Another poorly understood aspect of allergies is the idea of threshold. Allergic person A might experience a strong allergic reaction after exposure to .01grams of the allergen. Allergic person B might not experience a full reaction unless they are exposed to 5grams of the allergen (I'm making up random numbers.)
Allergies reactions are ranked on a scale, I think 1-5. But reaction level is very different from threshold. Person A might have a mild allergy (level 1 or 2) while person B has a strong (level 4 or5) allergic response.
Further...some allergic reactions are only triggered, I'm not quite sure how to say, but some reactions only occur when multiple factors occur at the same time. This is a bit tricky to explain in this space, but a person who has both a grass allergy and a milk allergy might be able to tolerate milk alone, but not MILK+GRASS TOGETHER at the same time. Again, this is part of why allergies, and related conditions, can be hard to diagnose.
A person with a - fairly severe wheat allergy may indeed be able to tolerate- at times- small amounts of wheat. They just have to carefully manage the quantity, AND they should understand
food allergy severity can change over time.
I'll toss out one more common misunderstanding: allergies are always triggered by proteins. They are NOT triggered by fats, for example. People with severe peanut allergies can often tolerate peanut OIL just fine, so long as it is HIGHLY REFINED peanut oil. HIGHLY REFINED peanut oil = almost pure oil, VERY low protein. A person with a very low threshold though may well react to even a very tiny bit of peanut protein,
so it is not safe to assume peanut oil is safe for every person with a peanut allergy.
It is therefore horribly incorrect, and very dangerous, to think that tolerating peanut OIL = that person can tolerate PEANUT PROTEIN.
Please, allergies are very complicated, confusing, and widely misunderstood. All of us would do well to be better informed, as many allergies go dangerously undiagnosed/misdiagnosed, for many years. This is a Disney forum, not a good place to get medical advice from me or anyone else. We should all seek reputable sources of information. When it comes to allergies, that can be difficult, as they are not well understood.
