Does baby formula have gluten in it?
Most baby formulas are gluten free.
Why are eggs and meat gluten and casein free although many of the animals are fed with grains that may contain both.
Meat, fish, eggs are gluten-free because even if the animals are fed with gluten-containing products, gluten is not absorbed as such, hence it does not appear in their blood and cannot reach their flesh. Likewise, in humans there is no gluten detectable in our blood.
I was diagnosed with celiac disease, ate gluten free for a while, and then slowly reintroduced gluten. Is this okay?
Bad idea! If the diagnosis was correct, you should never reintroduce gluten. Even in the absence of overt symptoms your gut will get inflamed and the consequences of untreated celiac disease will once again become possible.
What is the typical length of time a celiac patient experiences symptoms after having eaten gluten?
It's unique to each person and the amount of gluten ingested—normally a couple of days. The real concern is repeated ingestion, which can cause the most damage to those with celiac disease.
