In the USA, it’s estimated that about 1 in 100 people have celiac disease, a condition triggered by consuming gluten, a protein found in wheat, barley, and rye. For these individuals, gluten can wreak havoc on their gut and overall health. It's crucial for people with celiac disease to avoid gluten as it can damage their gut lining and lead to a host of unpleasant symptoms like digestive issues, fatigue, and more severe health problems over time.

While maintaining a gluten-free lifestyle is essential for those with celiac disease, others choose to go gluten-free for potential health benefits. Some find that reducing gluten improves their energy levels and digestion, although there isn’t extensive evidence supporting all the touted benefits.
