From Cookipedia(Redirected from Macadamia nuts)
The macadamia nut is the edible kernel from the nut of the macadamia tree, a small evergreen tree that is a native of eastern Australia. It is often eaten as a snack food.
As well as being delicious, they are good for you. As with all nuts, they contain no cholesterol, but they do contain high levels of monounsaturated fatty acids. Monounsaturated fatty acids reduce levels of blood cholesterol.
The macadamia nut's kernel is extremely hard to mine out of its shell (it requires about 300 psi to crack), but after some time in a warm and dry place the shell may develop cracks of its own. The nut can then be opened with a screwdriver.
Macadamia nuts are toxic to dogs. Ingestion may result in macadamia nut toxicosis, which is marked by weakness with the inability to stand within 12 hours of ingestion. Recovery is usually within 48 hours.
