Some dairy products may be OK for the lactose intolerant

Are you lactose intolerant? There’s a good chance that you can still eat foods like cheese and butter (often considered off-limits for people with lactose intolerance) without adverse — and potentially embarrassing — side effects.
One-half cup of vanilla ice cream has 4.9 grams of lactose.
A little background info: Lactose is a naturally occurring sugar that’s found primarily in dairy products, and it requires an enzyme called lactase in order to be digested.
People who don’t make enough of the lactase enzyme often experience symptoms of lactose intolerance, such as abdominal pain, gas, bloating and diarrhea, when they eat or drink lactose-containing foods such as milk or ice cream. Not a pleasant experience, to say the least.
Here’s why many people with lactose intolerance may still be able to indulge in certain dairy products without issue: Butter and many cheeses contain zero grams of carbohydrate, which means they contain zero grams of sugar. And zero sugar means zero lactose, or at least close to it. (Current labeling laws say that if a food contains less than 0.5 grams of carbohydrate or sugar per serving, these can be listed as zero on the nutrition facts label).
Compared to the 12-13 grams of lactose in a single cup of milk, less than 0.5 grams per serving isn’t much.
Yogurt is another popular dairy product often unnecessarily avoided by people with lactose intolerance. It contains more natural sugars than cheese (approximately 13 grams of lactose per cup of plain low-fat yogurt and 8-9 grams of lactose per cup of plain Greek yogurt), but the probiotics in yogurt actually help to digest the lactose for us.
Other dairy-based products that may be well-tolerated, depending on a person’s lactose sensitivity, include 100-percent whey protein powder (generally less than 1 or 2 grams of lactose per serving), half and half (less than 1 gram of lactose per 2-tablespoon serving), and cottage cheese (3 grams of lactose per half cup).
Fortunately, diagnosing lactose intolerance doesn’t have to be a guessing game. If you suspect that you may be lactose intolerant, try eliminating all types of lactose-containing foods and see if your symptoms improve. Gradually add products back in, one-by-one, starting with very-low-lactose foods like hard cheeses. As you add more and more lactose-containing foods, you’ll be able to determine your threshold for how much lactose you can tolerate. For example, you may find that cheese and yogurt are just fine, but milk and ice cream are a no-no’s.
If you find that even lower-lactose food and drink result in uncomfortable side effects, you still have plenty of options when it comes to dairy products and dairy substitutes.
Taking the lactase enzyme (in the form of Lactaid pills, for example) before eating or drinking dairy products can help to digest the lactose. And try lactose-free versions of milk, yogurt, cheese, and cottage cheese. (And if the lactose-free varieties still cause trouble, it’s possible that lactose intolerance isn’t the culprit, but that another type of intolerance or allergy is to blame).
Soy milk is naturally lactose-free, with nearly the same calcium and protein content as cow’s milk (other milk alternatives such as flax, almond, coconut and rice milks are often fortified with calcium and vitamin D, but have less protein). And although goat milk contains lactose (just slightly less than cow’s milk), many people report that they digest it better than cow’s milk.
The bottom line: Lactose intolerance doesn’t mean that you must eliminate dairy altogether. The key is to experiment to see what works, what doesn’t, and to know your limits.
