Consider the example set by the Albanians. When you think of health and long life, you're probably not likely to consider the tiny Mediterranean country of Albania. Doctors believe it has something to do with the lifestyle of the Albanian people.
Most Albanian people eat what has recently become known as the Mediterranean diet.
In part because they aren't as wealthy as other Europeans, Albanians eat little meat. Instead, they eat a diet rich in grains and vegetables. Much of the fat in their diet comes from monounsaturated fats like olive oil, which is much more healthy than saturated fats like butter and animal fat. Albanians also have one of the lowest rates for both smoking and alcohol consumption in Europe, and a higher rate of physical activity. Similar longevity effects are seen in neighboring countries Greece and Italy, which have the same kind of diets.
