Gluten-Free Foundations — Essentials, Swaps & Cross-Contact
What is it?
Gluten-free eating removes wheat, barley, rye (and their hybrids). This guide covers staple foods, smart flour swaps, label reading, and cross-contact basics to keep things simple and safe.
Quick start
- Base meals on naturally gluten-free foods: vegetables, fruit, plain meats/fish/eggs, legumes, nuts/seeds, dairy (as tolerated).
- Choose certified GF grains: rice, quinoa, buckwheat, corn/maize, certified GF oats*.
- Read labels every time—check for wheat, barley, rye, malt, and “contains gluten”.
*Oats: tolerance and regulations vary by country; use certified GF oats and follow local guidance.
Food lists (starter)
- Emphasise: fresh produce; potatoes, rice, quinoa; plain proteins; dairy or lactose-free options; olive oil; herbs/spices (single-ingredient).
- Use with caution: sauces, stocks, spice blends, processed meats, chips/snacks—check labels.
- Avoid: regular breads/pasta/couscous; wheat flour tortillas; barley (malt), rye bread/crackers; beer unless GF.
Flour & baking swaps
| Use for | Gluten-free swap ideas |
|---|---|
| All-purpose flour | GF all-purpose blend (with xanthan/psyllium), rice + tapioca + potato starch mix |
| Bread | GF bread mix + psyllium husk; buckwheat + sorghum blends |
| Thickening | Cornstarch, arrowroot, potato starch |
| Crumbing | GF breadcrumbs, ground almonds, crushed GF cornflakes |
Cross-contact basics
- Use a separate toaster or toaster bags; avoid shared crumbs.
- Dedicated utensils/boards or clean thoroughly before GF prep.
- Store GF staples on upper shelves; keep flours sealed to avoid dust spread.
- Fryers: shared oil can contaminate—ask if a dedicated fryer is used.
Label tips
- Scan for wheat, barley, rye, malt (incl. barley malt extract) and “contains gluten”.
- “May contain” = potential cross-contact—decide with your practitioner.
- Prefer products with certified GF logos where available.
