Hidden Sources of Gluten: Even Your Coffee Might Have It

Think gluten is only found in bread, chapati, cake, or pasta? What if I told you it could be hiding in your morning coffee?

Yes, some instant coffee brands use malted barley as a flavour enhancer, making them unsafe for people with Celiac Disease or gluten intolerance. Similarly, some flavoured teas contain barley or wheat-based thickeners.

So, what other surprising foods might contain gluten? Let's break it down.

1. Instant coffee and some teas

If you love coffee, be careful with instant varieties. Some brands add barley for taste or use wheat-based fillers. Similarly, certain flavoured teas (like chai mixes) may contain gluten-based thickeners.

What to do: choose pure coffee beans and certified gluten-free tea.

2. Processed meats

That juicy sausage or nyama choma marinade might contain gluten-based fillers. Many processed meats use wheat or barley as a binding agent, including sausages, meatballs, ham and cold cuts, and burgers (some use breadcrumbs).

What to do: always check the ingredients label or opt for certified gluten-free meats.

3. Spices and seasoning mixes

Some store-bought spice blends contain wheat flour as an anti-caking agent. Common culprits include stock cubes, gravy powders, and masala mixes.

What to do: stick to single-ingredient spices or check labels for gluten-free certification.

4. Soy sauce and other sauces

Most soy sauces contain wheat, making them a major hidden gluten source. Other risky sauces include ketchup (some brands use malt vinegar), salad dressings, teriyaki sauce, and barbecue sauce.

What to do: look for gluten-free soy sauce alternatives like tamari or coconut aminos.

5. Sweets and chocolates

Many candies and chocolates contain gluten in the form of barley malt, wheat starch, or other additives. Common culprits include malted chocolates (like Maltesers), wafers (like Kit-Kat), liquorice and gummy candies, and some chewing gums (which use wheat-based thickeners).

What to do: opt for gluten-free certified sweets and chocolates, and always check labels.

6. French fries and fried foods

Think fries are just potatoes? Not always. Many restaurants coat them in flour to make them crispier, or fry them in the same oil as battered foods. This can cause cross-contamination with gluten-containing items like fried chicken, samosas, and onion rings.

What to do: always ask how the fries are prepared, or make your own at home.

7. Medicine and supplements

Some pills and vitamins use gluten as a binder, especially chewable tablets and some painkillers.

What to do: ask your pharmacist for gluten-free medication options.

Final thoughts: stay vigilant, stay healthy

Gluten is sneaky, but with awareness and label-checking, you can avoid accidental gluten exposure. If you're living gluten-free, always ask questions, read ingredient lists, and opt for certified gluten-free products whenever possible.
