Neither contain more than trace quantities, with the exception of ricotta cheese. However, even ricotta has relatively small amounts of lactose and is unlikely to cause problems. When people who are lactose intolerant move to a region where it is common to drink milk, each generation becomes more tolerant of lactose. Dairy products are the major source of calcium in Australia. Those who are unable to tolerate much milk, therefore need to find some other good sources of calcium.
Cheese is an excellent source of calcium.
If yoghurt is tolerated, it also supplies a rich source of calcium. Small amounts of milk will also contribute. Fish with edible bones such as canned sardines and salmon are high in calcium, although a few people eat them often enough for them to be the major contributor. Small amounts of calcium are also found in average servings of almonds, green vegetables and oranges. Contrary to popular belief, sesame seeds are not a useful source of calcium unless they are ground into tahini paste.
