Frequently Asked Questions (FAQs)

1. Can people with celiac disease absorb calcium?

People with celiac disease may experience impaired calcium absorption, leading to bone alterations. The loss of villous cells in the proximal intestine, where calcium is actively absorbed, can contribute to this issue. Calcium malabsorption is particularly observed in acute celiac disease.

2. How can I get calcium without gluten or dairy?

There are several sources of calcium that are gluten-free and dairy-free. Some options include chia seeds, soy milk, almonds, dried figs, tofu, white beans, sunflower seeds, and broccoli rabe. These foods provide a good amount of calcium and can be incorporated into a gluten-free diet to ensure adequate calcium intake.
