What is Food Intolerance | Food Allergies- Should You be Worried?- Thomas DeLauer
Are you allergic to that food or are you just intolerant? I think we need to understand the immune system here and help you understand exactly what is happening inside your body when you have an allergic response to something versus an intolerance that might trigger some inflammation later on down the line. This is all very important stuff. Whether you’re doing a ketogenic diet, whether you’re fasting, or whether you’re just trying to live a healthy lifestyle, understanding how the immune system works when it comes down to our response to food is going to make your life a lot easier, but it’s also some pretty fun information in the first place. Hey, if you haven’t already, make sure you subscribe to my channel posting anywhere from three to seven videos a week, all kinds of crazy stuff, stuff when it comes down to keto, when it comes down to fasting, when it comes down to just general health. Also make sure you turn on notifications.
All right. Let’s get into the fun stuff. The first thing that I really want to talk about is a food allergy and what happens inside your body. Okay? A food allergy is a reaction that begins with a food shortly after eating it. You’ve probably heard of a food allergy before and you know what ends up happening. You might get them in the way of hives, you might get them in the way of maybe some rashes, or maybe you end up having to run to the bathroom or you end up getting some bloating. You know if you have a reaction to a food. You’ve probably experienced it before. Now that’s the simplicity of it, but let’s talk a little bit more about what’s actually happening.
You see, at the very, very root of it, when you have an allergy, it’s just a simple substance that is harmless that your body is responding to as if it was a harmful foreign invader. Basically, your body sees a food come in and it thinks that it’s bad, so it triggers a reaction, but there’s a pretty interesting process that occurs when it comes down to that. You see, that response that actually happens with that food is coming from something known as IgE. It’s a specific kind of protein, and we’re going to talk about these all in a second. They’re called immunoglobulins. Now in this particular case, this IgE protein attaches itself to the foreign invader, in this case, the harmless food that is labeled as a foreign invader. The IgE protein attaches itself to the foreign invader, and then from there it triggers multiple chemical responses, one of which is usually histamine. Now if you’ve ever taken an antihistamine before, this is what you’re fighting. You’re not fighting the IgE response. You’re fighting the histamine response. So here’s what’s interesting.
If you have allergies to multiple different foods, a lot of times you might find the reactions are similar amongst all those foods. Let’s say, for example, you’re allergic to shellfish and you’re allergic to peanuts. You might find that if you eat shellfish, you end up with your throat closing up. Well, you might find that if you eat peanuts, you end up having the same kind of reaction, and that’s simply because your reaction is to the histamine. It’s not really to the food. There’s a deeper problem going on where your body tends to recognize the shellfish or the peanuts as a foreign invader, triggering this already built-in mechanism that’s causing your throat to close up.
