An example of a triangle diagram appears to the right. An organizational chart is the diagram of a hierarchy within an organization, and is depicted in tree form below.
Cow's milk can range from 3.7 to 5.1% lactose, although most milk in the U.S. is around 5%. So water buffalo milk may be slightly lower in lactose but not significantly so. I certainly wouldn't call it a low lactose product.
Foods that are high in lactose are milk, cheese, yogurt and sour cream. Milk has the highest amount at 12 grams per cup. Cheese that has 1 gram of lactose per serving is considered to be low in lactose. Those cheeses include cheddar, Parmesan or Swiss, cream, cottage and ricotta.
