True feta cheese is a product of Greece and is made from at least 70 % goat's milk. The European Union has a "Protected Designation of Origin" standard, and Greece fought to have Feta recognized as being Greek. There are types of Feta made in other countries such as Denmark, but these may be made from cow's milk so do not have the same health benefits as the real Feta cheese.
Goat's milk Feta produced in Greece has a third less calories and a third less fat than other cheeses. It has only 264 calories in 3½ ounces and 21 grams of fat in the same quantity. It contains linoleic fatty acid which has strong antioxidant properties. Feta is a good source of protein and calcium (one ounce has 140 milligrams) which is necessary for healthy bones and teeth. Linoleic acid may, according to some research, aid in the loss of abdominal fat which results in a lower risk of diabetes and cardio-vascular diseases.
