Yes, it certainly can! My daughter has a reaction from just playing with Playdough. She doesn't get GI symptoms at first, just psychological mostly. It can get really bad. It's like night/day behavior. My daughter is eight, but started showing signs around 6.

The easiest way to remember the difference between the cholesterol types is HDL;   H=healthy equals healthy (omega 3, 7, limit 6 & 9 MCFA'S =Medium Chain Fatty Acids. 3= coconut oil, 7= sunflower oil, avocado. The higher your HDL the healthier you are & less likely to experience strokes, clogged arteries Etc. You can even use cold expeller pressed coconut oil on your skin and that is the best kind of coconut oil to eat as well. You want your HDL much higher than your LDL, it will help you stay healthy.   LDL;    L=Lousy. Meat fats, processed fats.  The higher your LDL is the more likely you will have strokes, clogged artery is, heart disease, fatty liver.   Then there's lipids... they are the culprit to be blamed for many heart attacks and things like that they are very small round particles that transport fats. You can have a low overall cholesterol reading and most of it be healthy cholesterol and have a ton of lipids and there's nothing you can do to change the lipid count. High number of lipids is very dangerous.   I'm going on statins is extremely dangerous if you ask me it's just completely my opinion, because I have seen so many of my elderly friends bleed to death internally because of the statins. I mean you wouldn't take all the oil and grease out of your car or a motorcycle and then try to drive it that way would you? You see that's what statins do they remove all of your bodies fats and it doesn't matter whether it's healthy fats or a lousy fats. It removes all of them and then your body can't function properly. You have to have fats to keep your skin supple and to stay warm. Your body also needs fats to digest & process certain nutrients, amino acids & vitamins.   Your brain is composed of fat so is that something you really want to remove with a pill every morning and night?   The thing about statins is that they also make the blood vessels and capillaries permeable. So this is how my friends who were on cardiac medication for a long time and statins ended up bleeding internally to death.   If you want to make sure that your heart is healthy, take odorless garlic at night and magnesium, vitamin K & calcium.     

It's also a symptom of EPI.

Yes.  Proportionately a small piece to a toddler is like a whole slice to an adult.  This is an important clue.  She was doing well, accidentally ate gluten and later the old behavior returned. I remember reading posts here of people reacting to a kiss from someone who had just eaten gluten. Recent research indicates that 40% of first degree relatives of someone with Celiac have undiagnosed Celiac Disease.  Father, mother, siblings.  There is a whole list of symtoms of "silent celiac".  Here is an article of symptoms possibly mistaken for other causes than Celiac Disease.  When I finally stopped gluten at 63 years old, I counted 19 things that improved, including lifelong mouthbreathing.  I never smelled bad things, so I as a kid, I learned to respond to the other kid's response in order to not seem weird. I really recommend you pursue testing for all the family if you can, and the whole family following GFD.  It is difficult at first, but the benefits will be worth it.  

I get these but where we are, they are called chicken potstickers. I would obviously suggest that it is the ginger in the product that is causing a stimulative digestive effect! So you might want to do what I do, just cook one of them with the rest of your meal so you don't have the same effect. I love the Feel Good products but they are on the expensive side. (I also drink Reed's ginger brew so in general, ginger is a friend of mine..when delivered at the right dose). Hope this helps and have a warm healthy week!
