(HealthDay News) -- If you are lactose-intolerant, you know you need to monitor your diet to prevent uncomfortable gas and bloating.

But dairy products aren't the only culprits. The National Digestive Diseases Information Clearinghouse lists these non-dairy foods that may also contain lactose:

• Margarine and different types of salad dressing.
• Deli meats (except kosher meats).
• Snack foods, including candy.
• Breads, baked products and processed cereals.
• Soups, meal-replacement supplements, instant potato products and instant breakfast drinks.
• Cookie, pancake and biscuit mixes.
