Bread and Crackers

Some manufacturers add lactose to bread or crackers, often as a sweetener. Whey may also appear—it’s a good preservative that keeps bread moist. Be sure to scan the ingredients list. It can be helpful to shop in the vegan section, especially if you’re unsure what a certain ingredient means.

Baked Goods and Frosting

OK, if you’re a baker, this probably isn’t so surprising. But most desserts, from cookies to cakes, contain some form of dairy. Cookies often contain butter, cake may contain butter and yogurt or milk, frosting is often made with milk or cream. If you’re offered a baked good at a party or restaurant, double-check before indulging. (If your kid is dairy-free, this can be a bummer, so you may want to pack a dairy-free treat from home.)

Getting discouraged? Here are delicious dessert recipes that DON’T contain dairy.

Hot Dogs and Sausages

Weird, right? Even “all beef” hot dogs sometimes contain dairy, as can sausages and even cold cuts. Look for kosher varieties to be sure they’re dairy-free. If your butcher makes sausage or roasts deli meat on-site, those products are less likely to contain added ingredients like dairy. Always ask!

Salad Dressings

Yep, those creamy salad dressings may get their creamy texture from lactose. Reduced sugar dressings in particular lean on added lactose to add a sweet, rich flavor. Luckily, it’s easy to make your own salad dressing, and most keep in the fridge for several days.

Canned Tuna

Here’s one of the most surprising foods that contain dairy. Some canned tuna brands add casein, a milk protein, to tuna as a filler. Always check the label, because it’s often listed as “hydrolized caseinate.”

Soup and Broth

Canned or boxed soups and meat or vegetable broths may contain some form of dairy, often milk solids. This includes the obvious cream-of-soups, but any soup or even plain broth isn’t a sure bet.

Instead, find a dairy-free dinner to serve the family.

One of the most surprising sources of dairy may be chewing gum. Look for “Recaldent,” sometimes found in Trident, or casein on the label.

Other Names for Milk and Dairy

Always read the ingredient label! In addition to milk, butter, and cream, dairy may appear as whey, casein, curds, milk by-products, milk solids or dry milk powder. If you see a product labeled with creamy-sounding words—creamed, cheese-flavored, chocolate-flavored—it will likely contain some lactose. The safest rule of thumb is assume you can’t eat something until you prove otherwise.
