Lactose hides far beyond milk and cheese — in bread, processed meats, sauces, sweets and 'non-dairy' creamers that still contain caseinate.
PickEat reads the label and flags milk derivatives, so a quick scan tells you if a product is lactose-free.
Some 'non-dairy' coffee creamers still list sodium caseinate — a milk protein — so 'non-dairy' on the front doesn't always mean lactose-free.
Lactose intolerance isn't a milk allergy
Lactose is the natural sugar in milk, and lactose intolerance means your body makes too little of the enzyme (lactase) needed to digest it. The result is digestive discomfort — bloating, cramps, wind — rather than an immune reaction. It's also usually dose-dependent: a splash of milk in coffee might be fine, a glassful isn't.
This is different from a milk (dairy) allergy, which is an immune response to milk protein and needs total avoidance of dairy. The distinction matters at the shelf, because a 'lactose-free' product still contains milk protein — it's just had the lactose broken down — so it suits lactose intolerance but not a milk allergy.
Where lactose hides
Lactose ranges far beyond milk, cheese and yoghurt. It's used as an ingredient and a filler in bread and baked goods, processed meats, instant soups, sauces, salad dressings, sweets and chocolate. Even some 'non-dairy' creamers contain caseinate, a milk derivative.
It also appears in non-food places — lactose is a common carrier in medicines, supplements and artificial sweeteners. Whey and milk powder are everywhere in processed food. Spotting all of this by eye is tedious, which is exactly where scanning every product pays off.
The dairy you may still tolerate
Not all dairy hits the same. Hard, aged cheeses like cheddar and parmesan are naturally very low in lactose because it's largely consumed during ageing, and butter contains only traces. Many people with lactose intolerance handle these comfortably even though they're dairy.
Because tolerance is individual and dose-dependent, the useful thing is to see how much lactose a product actually carries rather than treating all dairy as off-limits. PickEat flags milk derivatives so you can match your choices to your own threshold.
Making lactose-free shopping simple
Cutting lactose is mostly a matter of catching it in the unexpected products, since the obvious dairy is easy. That's where a quick scan beats a careful read — the app already knows the milk derivatives to look for.
Scan as you shop, learn which of your staples are clear, and reach for lactose-free or plant-based versions when something isn't. When a product does contain lactose, PickEat names the source so you know what tripped it.

Frequently asked questions
Can PickEat tell me if a food contains lactose?+
Yes. PickEat scans for milk and its derivatives — whey, casein, milk powder and lactose used as a carrier — and tells you whether a product is lactose-free.
Does it catch casein in 'non-dairy' products?+
Yes — caseinate in 'non-dairy' creamers and similar items is flagged.
Is lactose-free the same as dairy-free?+
No. Lactose-free products still contain milk protein, so they suit lactose intolerance but not a milk allergy. For a milk allergy, choose dairy-free or plant-based products, which PickEat can flag too.
Can I still eat hard cheese?+
Often yes — aged cheeses like cheddar and parmesan are naturally very low in lactose. Tolerance is individual, and PickEat helps you see how much dairy a product carries.
Is it free?+
Yes, scanning is free on iOS and Android.
