How much lactose is there in cheese?
The good news for the lactose-intolerant is that there is much less lactose in cheese than in milk. A cup of cow’s milk contains about 10-12 grams of lactose. An ounce of Swiss or Cheddar cheese contains less than one gram of lactose. Most of the lactose found in cheese is removed with the whey during the cheese making process. The rest is consumed by the culture in the first few weeks of aging.
